An Aircraft Factory Manufactures Airplane Engines. The Unit Cost C (the Cost In Dollars To Make Each

Answers

Answer 1

There are 320 engines must be made to minimize the unit cost.

What is an expression?

Expression in math's is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that;

The unit cost is given by the function,

⇒ C(x)= 0.3x²- 192x + 47,470

Now,

Since, The unit cost is given by the function,

⇒ C(x)= 0.3x²- 192x + 47,470

Hence, We get;

⇒ dC/dx = 0.6x - 192

Put dC/dx = 0

⇒ 0 = 0.6x - 192

⇒ 0.6x = 192

⇒ x = 320

And, d²C/dx² = - 192 < 0

Hence, This gives the maximum value.

So, The number of engines which must be made to minimize the unit cost = 320

How to determine the length of missing side and the measure of the missing angle

In this question we have a geometric system formed by a equilateral triangle divided into two triangles by a line segment. The missing sides and angles can be found by means of algebra properties, Euclidean geometry and trigonometry.

First, obtain the missing side by taking approach of properties for equilateral triangles:

y = 46 - 16

y = 30

Second, find the length of line segment by law of cosine:

l = √(46² + 16² - 2 · 46 · 16 · cos 60°)

l ≈ 40.447

The missing length is approximately 40.447.

Third, the measure of the missing angle by law of sine:

16 / sin x = 40.447 / sin 60°

sin x = (16 / 40.447) · sin 60°

sin x = 0.343

find the slope of the line that passes through T(-2,11) U(3,11)

Answers

Answer:

Step-by-step explanation:

use equation [tex]\frac{y2-y1}{x2-x1}[/tex] to calculate the slope, in this case the slope would be [tex]\frac{11-11}{3-(-2)}=\frac{0}{6} =0[/tex]

The slope would be 0 for the line,

another way we can tell the slope is 0 is that we can see the two sets of coordinates are on the y=11, they just have different x coordinates.

But the equation above shows the complete work and supported the answer.

Answer:

Slope (m) = 0

Step-by-step explanation:

Given coordinates,

→ T(-2, 11)

→ U(3, 11)

Formula we use,

→ Slope = (y2 - y1)/(x2 - x1)

Now required slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (11 - 11)/(3 -(-2))

→ m = (0)/(3 + 2)

→ m = 0/6

→ [ m = 0 ]

Therefore, the slope is 0.

The probability of a seed not growing is 0.46, because if it has a 54% chance of growing, then  100% - 54% to find the odds that it will not grow, which is 46%.

The probability of 7 seeds growing is equivalent to asking what the probability is of a seed growing and another seed growing and another seed growing and another seed, and so on until I say a total of 7seeds. The point is that "and" in probability means to multiply.

To calculate the likelihood of seven seeds growing,

Definitions

An open circle indicates the value is not included in the interval.A closed circle indicates the value is included in the interval.An arrow shows that the function continues indefinitely in that direction.

Interval notation

( or ) : Use parentheses to indicate that the endpoint is excluded.[ or ] : Use square brackets to indicate that the endpoint is included.

The domain is the set of all possible input values (x-values).

The range is the set of all possible output values (y-values).

Question 32

From inspection of the graph, the endpoints of the continuous curve are:

(-6, 0) and (6, -6)

As the endpoints are open circles, the x-values are excluded from the domain.  Therefore, the domain in interval notation is:

Domain:  (-6, 6)

The smallest y-value is y = -6 and the greatest y-value is y = 2.  

y = -6 is excluded from the range since it is the y-value of the open circle endpoint, whereas y = 2 is included in the range.  Therefore, the range in interval notation is:

Range:  (-6, 2]

The graph is a function as is each input (x-value) is related to exactly one output (y-value).

Question 33

From inspection of the graph, the endpoints of the continuous line are:

(-6, -1) and (6, 5)

As the graph is a straight line, the x and y values of the endpoints are the x and y values of the domain and range.

As the (-6, -1) endpoint is an open circle, the values are excluded from the domain and range.

As the (6, 5) endpoint is a closed circle, the values are included in the domain and range.

Therefore, the domain and range in interval notation are:

Domain:  (-6, 6]Range:  (-1, 5]

The graph is a function as is each input (x-value) is related to exactly one output (y-value).

This is in contrast to a positive slope, where as the value of x increases, the value of y also increases. So, if the slope of the line y = x is changed to a negative value, the line will still have the same general shape, but it will be flipped upside-down and will slope downward from left to right

You want the different names for the angles shown, and for their parts.

This question is about naming bits of geometry. Here, you're mainly naming rays and combinations that form angles. A ray is always named by naming its end point first, then another point on the ray. An angle is formed by two rays with a common end point.

(a) ∠2

An angle can be named by naming rays that form it (with the vertex in the middle of the name), by naming the vertex alone (if that is unambiguous), or by using a designator, such as ∠2.

Angle 2 is made from rays FH and FE, so can be named either of ...

∠HFE∠EFH

If ray FG were not present, it could also be named angle F, the name of the vertex point.

(b) ∠GFE

The 3-letter angle name tells you the names of the sides. The end point of each ray must be named first in the ray name. It is named in the middle of the angle name.

Jacket and Jill are planning to meet at the top of the hill. Jack is 2 miles away and Jill is 3 miles away. Jill walks 1.5 miles per hour faster than Jack. It takes them the same amount of time to get there. What are their rates and how long will it take?

Answers

Answer:

Jacks Rate: 3 miles per hour

Jills Rate: 4.5 miles per hour

Time: 40 minutes or 2/3 of an hour

Step-by-step explanation:

Setting up the Algebraic Expressions:

This problem in it self isn't necessarily too complex, but a crucial part of it is taking the context given and somehow making that into a algebraic expression which we can then use to solve the equation.

Assigning Unknowns and Variables:

So let's first assign two unknowns to the rates at which Jack and Jill walk. Since both of there names start with J, I'll use a subscript to differentiate between the two.

[tex]\text{let }J_a=\text{Jack's walking rate}\\\text{let }J_i = \text{Jill's walking rate}[/tex]

Notice that both have a J, but there is a little letter to the right and below, which is a subscript. This way we can easily tell which person we are referring to while not having to write out their entire name as a variable.

Now let's assign two variables. First let's assign distance: [tex]D=\text{distance from top of hill}[/tex]

and let's also assign time to a variable: [tex]t = \text{time in hours}[/tex]

Deriving Equations:

Now let's start making some equations! If jack is two miles away from the top of the hill, in general, the distance from the hill can be calculated using the following equation: [tex]D=2-t*j_a[/tex]

Essentially, Jack starts off with a distance of two miles away, and after one hour, Jack will walk [tex]j_a[/tex] miles, this is his rate, what Jake travels in one hour. After another hour passes, he will do the same thing, but twice. So this is why we're multiplying by time. Since for each hour that passes, he will walk a further: [tex]j_a[/tex] miles, meaning he will be that much closer, so we subtract it from 2, the initial distance.

The same logic can be applied to Jill, except with an initial distance of 3 miles and using the unknown: [tex]j_i[/tex] which is Jill's rate. So we get the following equation: [tex]D=3-t*j_i[/tex]

If we're looking for when they reach the top of the hill, that means that the distance from the hill is zero. So let's set both equations to zero.

[tex]0=3-t*j_i\\0=2-t*j_a[/tex]

From here let's solve for time for both equations. So let's start with the first equation.

[tex]0=3-t*j_i[/tex]

From here let's subtract 3 from both sides to get rid of the 3 on the right side.

[tex]0-3=(3-3)-t*j_i\implies-3=-t*j_i[/tex]

from here let's divide both sides by Jill's rate.

[tex]\frac{-3}{j_i} = \frac{-t*j_i}{j_i} \implies \frac{-3}{j_i}=-t[/tex]

From here let's divide both sides by -1 to get t isolated.

[tex]\frac{\frac{-3}{j_i}}{-1} = \frac{-t}{-1} \implies \frac{3}{j_i}=t[/tex]

We can essentially apply the same steps to the equation we derived from Jack's rate.

[tex]0=2-t*j_a\\\\(0-2)=(2-2)-t*j_a \implies -2 = -t*j_a\\\\ \frac{-2}{j_a} = \frac{-t}{j_a} \implies \frac{-2}{j_a} = -t\\\\\frac{\frac{-2}{j_a}}{-1} = \frac{-t}{-1} \implies \frac{2}{j_a} = t[/tex]

Now we have the equations:

[tex]\frac{2}{j_a} = t\\\\\frac{3}{j_i} = t[/tex]

and this represents the time needed to reach the top of the hill (since we set both equations equal to zero)

Substituting and Solving:

From here we need to look once more at the question, specifically where it says: "It takes them the same amount of time to get there". So we set the equations equal to each other.

[tex]\frac{2}{j_a} = \frac{3}{j_i}[/tex]

Now we use our last piece of needed context: "Jill walks 1.5 miles per hour faster than Jack".  We can set up one more equation: [tex]J_i = J_a+1.5[/tex].

This is super useful to have, since we can now make a substitution give this equation, converting our two-variable equation into a one-variable equation, allowing us to solve for one numerical value.

We have: [tex]\frac{2}{j_a} = \frac{3}{j_i}[/tex] and we know that: [tex]J_i = J_a+1.5[/tex], so let's simply plug in [tex]J_a+1.5[/tex] for [tex]j_i[/tex].

This gives us the equation:

[tex]\frac{2}{J_a}= \frac{3}{J_a + 1.5}[/tex].

Cross Multiply:

[tex]2(J_a+1.5) = 3(J_a) \implies 2J_a + 3 = 3J_a[/tex].

Subtract [tex]2J_a[/tex]:

[tex]3=J_a[/tex].  

We can solve for Jills value, since Jill's value is just 1.5 miles per hour more than this, so [tex]J_i = 3+1.5=4.5[/tex]

Now let's take Jacks value and substitute it into his time equation

[tex]t = \frac{2}{3}[/tex]

we can keep this in hours, or we can convert this into minutes. We can convert this in to minutes by multiplying the amount of minutes in an hour by 2/3, so: [tex]60 * \frac{2}{3} = \frac{120}{3} = 40\text{ minutes}[/tex]

Find the equation of the exponential function represented by the table below:

Answers

The equation of the exponential function represented by the table will be:

[tex]f(x) = 2(4)^{x}[/tex]

An exponential function is a Mathematical function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

We know the equation of exponential function such as

[tex]f(x) = ab^{x}[/tex]

Put x=0, and y=2 in the function

[tex]2 = ab^{0} \\2 = a[/tex]

Also x=1, and y=8 in the function

[tex]8 = 2b^{1} \\b = 4[/tex]

Thus,

[tex]f(x) = ab^{x} \\f(x) = 2(4)^{x}[/tex]

Therefore, the equation of the exponential function represented by the table will be:

[tex]f(x) = 2(4)^{x}[/tex]

The Banana Apple company sells its Golden, Macintosh, and Red Ida apples in mixes Box A costs 3€, Box B 3€ and Box C 4€. Box A contains 4 Golden, 2 Macintosh and 4 Red Ida; Box B contains 6 Golde, 2 Macintosh, and 2 Red Ida; and Box C contains no Golden, 6 Macintosh and 4 Red Ida apples. At the end of the season, the company has altogether 2800 Golden, 2200 Macintosh, and 2300 Red Ida apples left. Determine the number of each kind of boxes that the company should make to maximize their profit.

Answers

Answer:

To maximize profit, the Banana Apple company should determine the number of each kind of apple box that they should make. To do this, they need to know the number of each type of apple that they have, as well as the price of each box.

Based on the information provided, the company has 2800 Golden apples, 2200 Macintosh apples, and 2300 Red Ida apples. This means that they can make 700 Box A's (2800 / 4 = 700), 1100 Box B's (2200 / 2 = 1100), and 575 Box C's (2300 / 4 = 575).

The price of each box is also given: Box A costs 3€, Box B costs 3€, and Box C costs 4€. This means that if the company makes 700 Box A's, they will earn 2100€ (700 x 3 = 2100€), if they make 1100 Box B's, they will earn 3300€ (1100 x 3 = 3300€), and if they make 575 Box C's, they will earn 2300€ (575 x 4 = 2300€).

To maximize profit, the company should make as many of the most profitable box as possible. In this case, the most profitable box is Box B, which earns 3€ per box. The company should make 1100 Box B's, which will earn them a total of 3300€.

Answer:

To solve this problem, we need to determine how many boxes of each type the company should make to maximize their profit. We can set up a system of equations to represent the number of apples in each box and the total number of apples the company has.

Let's call the number of boxes of type A x, the number of boxes of type B y, and the number of boxes of type C z. We can represent the number of apples in each box using the following equations:

x + y + z = 2800

4x + 6y + 0z = 2200

2x + 2y + 6z = 2300

To maximize the profit, the company should make as many boxes as possible while still having enough apples to fill all the boxes. We can solve this system of equations using substitution to find the values of x, y, and z that maximize the profit.

First, we can solve the first equation for z in terms of x and y:

z = 2800 - x - y

Next, we can substitute this expression for z into the second and third equations to eliminate z:

4x + 6y + 0(2800 - x - y) = 2200

4x + 6y = 2200

2x + 2y + 6(2800 - x - y) = 2300

2x + 2y + 17600 - 6x - 6y = 2300

2x + 2y = -15300

We can then solve this system of equations using substitution. From the second equation, we have:

4x + 6y = 2200

2x + 2y = -15300

We can solve the second equation for y in terms of x:

y = -15300/2 - x/2

We can substitute this expression for y into the first equation to solve for x:

4x + 6(-15300/2 - x/2) = 2200

4x - 45300 - 3x = 2200

x = (2200 + 45300) / (4 - 3)

x = 13600/1

x = 13600

We can then use this value of x to find the value of y:

y = -15300/2 - 13600/2

y = -13650

Finally, we can use these values of x and y to find the value of z:

z = 2800 - 13600 - (-13650)

z = 1650

Therefore, the company should make 13600 boxes of type A, -13650 boxes of type B, and 1650 boxes of type C to maximize their profit.

PLEASE ANSWER I NEED HELP

Answers

a. The orthocenter for the coordinates (0,0), (6,3), and (3,24) is (24, 2).

b. The orthocenter for the coordinates (5,3), (8,6), and (4,10) is (8, 6).

What is an orthocenter?

The orthocenter is the point where the altitudes of the triangle coincide. An obtuse triangle, will be outside the triangle. For a right triangle, it will be the right angle vertex. Of course, each altitude is a line through a vertex and perpendicular to the opposite side.

The equation can be written as,

y -y₃= -(x₂ -x₁)/(y₂ -y₁)(x -x₃)

This can be rearranged to something resembling standard form:

(x₂ -1x₁)(x -x₃) +(y₂-y₁)(y -y₃) = 0

(x₂ -x₁)x +(y₂ -y₁)y = (x₂ -x1)x₃ +(y₂ -y1)y₃ . . . . line through P3, ⊥ to P1P2

Part(a).

For the first altitude, we choose P1 = (0, 0), P2 = (7, 3), and P3 = (3, 51). This gives,

(x₂-x₁) = 7 -0 = 7

(y₂ -y₁) = 3 -0 = 3

altitude equation = 7x +3y = 7·3 +3·51 = 174

For the second altitude, we choose P1 = (0, 0), P2 = (3, 51), and P3 = (7, 3). This gives,

(x₂ -x₁) = 3 -0 = 3

(y₂ -y₁) = 51 -0 = 51

altitude equation = 3x +51y = 3·7 +51·3 = 174

Finding the point of intersection of these two equations can be done in a number of ways. Cramer's Rule provides a quick solution:

x = ((3)(-174) -(51)(-174))/(7·51 -3·3) = 8352/348 = 24

y = ((-174)(3) -(-174)(7))/348 = 696/348 = 2

The orthocenter for the triangle is (24, 2).

Part(b).

We can use the method just described, or we can verify the triangle is a right triangle, as it appears to be when the points are plotted.

The slope of P1P2 is (6 -3)/(8 -5) = 3/3/ = 1.

The slope of P2P3 is (10 -6)/(4 -8) = 4/-4 = -1

These slopes have a product of -1, so the segments are perpendicular. The vertex P2 has the right angle, hence the orthocenter.

The orthocenter for the triangle is (8, 6).

A simple random sample of 500 individuals provides 250 Yes responses. a. What is the point estimate of the proportion of the population that would provide Yes responses (to 2 decimals)? b. What is your estimate of the standard error of the proportion (to 4 decimals)? c. Compute the 95% confidence interval for the population proportion (to 4 decimals).

Answers

a) The point estimate of the proportion of the population that would provide Yes responses is; 0.50

b) The estimate of the standard error of the proportion is; 0.0224

c) The 95% confidence interval for the population proportion is; CI = (0.4569, 0.5431)

How to calculate the confidence interval?

a) The point estimate of proportion in a sample of n out of which x belongs to the favorable event is;

p^ = x/n

Thus, we are given; x = 250 and n = 500

p^ = 250/500

p^ = 0.5

b) The standard error  is defined as a statistical term that measures the accuracy with which a sample distribution represents a population by using standard deviation. It is given by the formula;

S = √(p^(1 - p^)/n)

Plugging in the relevant values gives;

S = √(0.5(1 - 0.5)/500)

S = 0.0224

c) A confidence interval is defined as the mean of your estimate plus and minus the variation in that estimate. The confidence interval is given by the formula;

CI = p^ ± z√(p^(1 - p^)/n)

where z is z-score at confidence level

z at 95% confidence level = 1.96

Thus;

CI = 0.5 ± 1.96√(0.5(1 - 0.5)/500)

CI = 0.5 ± 0.04312

CI = (0.4569, 0.5431)

You want to format a 64GB USB disk to use it in Windows. Which file system should you use? FAT FAT32 ONTFS​

Answers

Answer: FAT32

you're welcome :D

Answer:

use fat32

FAT32 is regarded as the default file system for external drives, especially the removable USB flash drives and SD memory cards. It's the most compatible file system that can be used on major devices and operating systems like Windows and macOS. So, the advantage of using FAT32 is portability.

However, FAT32 has some disadvantages, or let's say limitations as well. First and foremost, if you use a single file over 4GB in size, you'll need to convert FAT32 to NTFS or exFAT; What's more, due to the manufacturers' specifications, FAT32 can only be used to format drives between 2GB and 32GB, and that's why native tools on Windows have that limit, too. When you try to format a USB drive over 32GB in Windows Explorer, there is no "FAT32" option at all.
