A sign company is building a sign with the dimensions shown.
What is the area of the sign?

Answer:

Below

Step-by-step explanation:

With roots   -4   and 6  

the equation is   a * (x+4)(x-6) = 0  

     'a' can be any real number (I'll choose '1')

Expand to  x^2 -2x - 24 = f(x)

we have

f(x)=6x+2

g(x)=-5x-9

Find out the product

so

f(x)*g(x)=(6x+2)*(-5x-9)

Applying distributive property

f(x)*g(x)=(6x)*(-5x)+(6x)*(-9)+(2)*(-5x)+(2)*(-9)

f(x)*g(x)=-30x^2-54x-10x-18

combine like terms

f(x)*g(x)=-30x^2-64x-18

We are looking at what type of variables are given. Let's analyze it one by one to check which one suits it best.

(a) Temperature

Temperature is measured by numbers, hence, this is categorized as a quantitative variable. Temperature does not have a non-finite value since it changes as time goes by, hence, the level of measurement for this type of variable is ratio.

Answer: Quantitative and ratio

(b) Dosage of the medication

The dosage of medication is measured in milligrams, which means we are dealing with numbers, hence, this is a quantitative variable. In the case of dosage, we are dealing with fixed values, hence, the level of measurement for this type of variable is interval.

Answer: Quantitative and interval

(c) Stock exchange

Stock exchanges are types of group variables. These are represented as categories, hence, this variable is classified as categorical. The exchanges are ranked in some specific order. When dealing with categorical variables that have rank order, we have ordinal variables.

Answer: Categorical and ordinal

Note that:

• All numbers whose final digit is 0 or an even number are divisible by 2

• All numbers whose final digit is 0 are divisible by 10

• 498 is divisible by 2 but not divisible by 5 and 10

• 151 is not divisible by any of 2, 5, or 10

• 150 is divisible by al of 2, 5, and 10

Shifts on x, where x and k form a binomial, are horizontal shifts. If k is positive, it is a left shift. If k is negative, it is a right shift.

The constant final term of the equation acts in the opposite way. It will be a vertical shift, and positive will mean up, negative will mean down.

So here, where there is a positive horizontal shift of 2 and a negative vertical shift of 7, the function is shifted 2 units to the left and 7 units down.

Answer:

7 would be the closest meter when rounded 7 times 3 is 21 so its one-off but the closest you can get so the answer is 7 meters

Step-by-step explanation:

I divided 22 by three because the way to solve for the area is length times width so it'd be area divided by width for length

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given functions

STEP 2: Describe the transformations

Translation to the left/right: Horizontal translation refers to the movement toward the left or right of the graph of a function by the given units. The shape of the function remains the same. It is also known as the movement/shifting of the graph along the x-axis.

To shift, move, or translate horizontally, replace y = f(x) with y = f(x + c) (left by c) or y = f(x - c) (right by c).

Translations up/down: The graph of a function can be moved up, down, left, or right by adding to or subtracting from the output or the input. Adding to the output of a function moves the graph up. Subtracting from the output of a function moves the graph down.

To translate the function up and down, you simply add or subtract numbers from the whole function. If you add a positive number (or subtract a negative number), you translate the function up. If you subtract a positive number (or add a negative number), you translate the function down.

STEP 3: Define the first transformation

STEP 4: Define the vertical transformation

STEP 5: Define the final transformation

Hence, the transformations of f(x) to g(x) are:

Translated 2 units left

Translated 3 units down

Reflected over the x-axis (yes)

The ratio of WXYZ to EFGD can be determine by taking the ratio of any of the simila side of WXYZ to EFGD.

That is;

Since EFGD is a rectangle, using the property of the rectangle that state " opposite sides are congruent, we can deduce that ED = EG = 6

Hence,

ANSWER

1/2

Let the width of the field = w

∵ The length is four times as the width

∵ The width = w

∴ The length = 4w

∵ The length is decreased by 10 feet

∴ The new length = 4w - 10

∵ The width is increased by 2 feet

∴ The new width = w + 2

The new perimeter is 80 feet

∵ The perimeter of the rectangle = 2(length + width)

Let us simplify it

Now equate it by 80

Add 16 to both sides

Divide both sides by 10

The length is 4 times the width

The length is 38.4 feet and the width is 9.6 feet

Answer: To do that, we divide both sides by 3. Thus, the answer to "3 times what equals 27?" is 9. To double-check our work, multiply 9 by 3 to see that it equals 27.

The domain and the range of the function are {−5, −2, 1 ,5} and {−26, −14, −2} respectively

From the question, we have the following parameters that can be used in our computation:

Function: f(x) = 4x - 6

Table of values

x −5 −2 1 5

y −26 −14 −2 −14

The set of x values is the domain

So, we have

Domain = {−5 −2 1 5}

Rewrite as

Domain = {−5, −2, 1 ,5}

The set of y values is the range

So, we have

Range = {−26 −14 −2 −14}

Rewrite as

Range = {−26, −14, −2}

Hence, the range is {−26, −14, −2}

In this question, we are given two similar triangles ABC and DEF.

Similar triangles:

The triangles are similar if they have congruent corresponding angles and the corresponding sides of triangles are in proportion.

Therefore, the proportion of all sides should be the same. To proportion (k) can be found using:

k = Side AB / side DE

k = 9/6

or

k = 3/2

Similarly, the 'k' should be the same for side BC and side EF. Therefore,

k = side BC/ side EF

Now, put the values in the equation

Therefore, the value of x would be 4.

The mass of the object that the star is orbiting is 1.0659 × 10³⁷ kg.

One of the fundamental quantities and the most fundamental feature of matter is mass. The quantity of matter in a body is referred to as its mass. The SI unit of mass is the "kilogram," or kg, while there are other units for determining mass, such as grams, pounds, pounds, etc. A good conversion formula can be used to convert any mass unit to another without changing the meaning or essence of the quantity being measured.

Given, the speed of the orbiting star is 1400 km/s.

Converting the speed in meter per second.

speed = 1.4 × 10⁶ m/s

The radius of the circular orbit is 14-day light.

Converting the radius in meters,

radius = 3.626 × 10¹⁴ m

We know that the gravitational constant = 6.67 × 10⁻¹¹ N.m²/kg².

Now, find the mass of the object:

mass = ((1.4 × 10⁶)² × 3.626 × 10¹⁴)/6.67 × 10⁻¹¹

         = (1.96 × 10¹² × 3.626 × 10¹⁴)/6.67 × 10⁻¹¹

         = (7.10696 × 10²⁶)/6.67 × 10⁻¹¹

         = 1.0659 × 10³⁷ kg

Therefore, the mass of the object that the star is orbiting is 1.0659 × 10³⁷ kg.

Answer:

Step-by-step explanation:

Just did it on khan academy.

To find the equation of the line that goes through the point (4, -7) and is perpendicular to the line y + 6 = -2/5 (x - 1), we can use the fact that two lines are perpendicular if their slopes are negative reciprocals of each other.

The slope of the line y + 6 = -2/5 (x - 1) is -2/5, so the slope of the line that is perpendicular to it must be -5/2. We can use this slope and the point (4, -7) to write the equation of the line in slope-intercept form.

To do this, we can use the point-slope formula, which is: y - y1 = m(x - x1), where (x1, y1) is the point through which the line passes, and m is the slope of the line. In our case, the point is (4, -7) and the slope is -5/2, so the equation of the line is: y - (-7) = (-5/2)(x - 4).

We can simplify this equation to get: y + 7 = -5/2 x + 10. Finally, we can rearrange the terms to get the equation in slope-intercept form, which is: y = -5/2 x - 25/2.

Therefore, the equation of the line that goes through the point (4, -7) and is perpendicular to the line y + 6 = -2/5 (x - 1) is y = -5/2 x - 25/2 in slope-intercept form.

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]y+6=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{2}{5}}(x-1)\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{\cfrac{-2}{5}} ~\hfill \stackrel{reciprocal}{\cfrac{5}{-2}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{5}{-2}\implies \cfrac{5}{2}}}[/tex]

so we're really looking for the equation of a line whose slope is 5/2 and that it passes through (4 , -7)

[tex](\stackrel{x_1}{4}~,~\stackrel{y_1}{-7})\hspace{10em} \stackrel{slope}{m} ~=~ \cfrac{5}{2} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-7)}=\stackrel{m}{ \cfrac{5}{2}}(x-\stackrel{x_1}{4}) \implies {\large \begin{array}{llll} y +7= \cfrac{5}{2} (x -4) \end{array}}[/tex]
