I Need Help On Question 6 And Simple Explanation Please (8th Grade Algebra)

Answers

Answer 1

ANSWER

Linear function

EXPLANATION

6) To solve this, we have to observe the given data.

Notice that as each term comes, the circles are dropped by a specific factor:

Term 1: 16

Term 2: 8

Term 3: 4

Term 4: 2

Therefore, we see that the number of circles reduces by a certain factor which is ¹/ ₂.

Hence, there is a proportional relationship between the term and the number of circles.

Therefore, a proportional function will be used to model the pattern:

[tex]y=\frac{1}{2}x[/tex]

This is also the form of a linear function without the constant. Hence, the answer is a linear function.

One of the largest carnivals has 25 rides and accommodates 120 people on each ride. If every ride was was completely full 4 nights this week, how many people will the carnival accommodate during those 4 nights?

Answers

The carnival has 25 rides

Each ride accomodates 120 people (when full)

Each ride was completelly booked for 4 nights .

Step one, calculate how many people can the carnival accomodate in one night by multiplying the number of people by ride by the number of rides:

120*25= 3000

This means that in one night, the carnival can accomodate 3000 people in all 25 rides.

Step two, multiply the value obtained by the number of nights the carnival will be full:

3000*4=12000

The carnival will expect to accomodate 12000 people for 4 nights with all rides full booked.

36 inches 23 inches is what fraction of a yard

Answers

If a yard contains 36 inches, then 21 inches is the 7/12 fraction of a yard

A yard contains 36 inches

We know

One yard = 36 inches

Here we have to use the unitary method for the conversion

The unitary method is the method of the value of a single unit.

36 inches = 1 yard

Then one inch = 1 / 36 yard

21 inches = (1 / 36) × 21

Multiply the terms

= 21 / 36

Divide both numerator and denominator by 3

= (21 / 3) / (36 / 3)

Divide the terms

= 7 /12 yard

Hence, if a yard contains 36 inches, then 21 inches is the 7/12 fraction of a yard

The complete question is

A yard contains 36 inches. 21 inches is what fraction of a yard ?

Find the circumference and area of each. Round for the nearest tenth:

1) a circle has a radius of 2 meters
2) a circle has a diameter of 16 cm
3) a circle has a radius of 8ft
4) a circle has a diameter of 11 cm

Answers

Answers:

1) C = 12.6 m

A = 12.6 m²

2) C= 50.3 cm

A = 201.1 cm²

3) C= 50.3 ft

A = 201.1 ft²

4) C= 34.6 cm

A = 95.0 cm²

Explanation:

The circumference and area of a circle with radius r can be calculated as:

[tex]\begin{gathered} \text{Circumference = 2}\pi r \\ Area\text{ = }\pi r^2 \end{gathered}[/tex]

Where π is approximately 3.1416

Then, for each option, we get:

1) Replacing the radius by 2 m, we get:

[tex]\begin{gathered} \text{Circumference}=2(3.1416)(2m)=12.6m \\ \text{Area}=(3.1416)(2m)^2=(3.1416)(4m^2)=12.6m^2 \end{gathered}[/tex]

2) If the diameter is 16 cm, the radius is 8 cm because the radius is half the diameter. So, replacing r by 8 cm, we get:

[tex]\begin{gathered} \text{Circumference = 2(3.1416)(8cm) = 50.3cm} \\ \text{Area = (3.1416)(8cm)}^2=(3.1416)(64cm^2)=201.1cm^2 \end{gathered}[/tex]

3) Replacing r by 8 ft, we get:

[tex]\begin{gathered} \text{Circumference = 2(3.1416)(8ft) = 50.3ft} \\ \text{Area = (3.1416)(8ft)}^2=(3.1416)(64ft^2)=201.1ft^2 \end{gathered}[/tex]

4) If the diameter is 11 cm, the radius is 11/2 = 5.5 cm, so:

[tex]\begin{gathered} \text{Circumference = 2(3.1416)(5.5cm) = 34.6 cm} \\ \text{Area = (3.1416)(5.5cm)}^2=(3.1416)(30.25cm^2)=95.0cm^2 \end{gathered}[/tex]

¿Cual es el resultado de efectuar (2x+5)³ + (x-2)(x-2)?

Answers

The equation (2x+5)³ + (x-2)(x-2) we get 8x³ + 60x² + 150x +129.

What is meant by binomial equation?

A binomial number is an integer that can be produced by evaluating a homogeneous polynomial with two terms in mathematics, more specifically in number theory. It is a Cunningham number that has been generalized.

Let the equation be (2x + 5)² + (x -2)(x- 2)

By using binomial formula we get,

(a + b)³ = a³ + 3a²b + 3ab² + b³

The coefficient multipliers are located in row 3 of Pascal's triangle.

(2x + 5)³ + (x - 2)(x - 2)

= 8x³ + 60x² + 150x +125(x - 2)(x - 2)

8x³ + 60x² + 150x + 125 + x(x - 2) - 2(x-2)

8x³ + 60x² + 150x + 125 + x² - 2x - 2x +4

simplifying the above equation, we get

8x³ + 60x² + 150x + 125 + x² - 4x +4

8x³ + 60x² + 150x +129 + x² - 4x

8x³ + 60x² + 150x + 129 - 4x

8x³ + 60x² + 146x + 129

= 8x³ + 60x² + 150x +129

Therefore, by simplifying the equation (2x+5)³ + (x-2)(x-2) we get 8x³ + 60x² + 150x +129.

Rewrite each equation in slope-intercept form, if necessary, then determine whether the lines are parallel , perpendicular, or neither.A.) y=2×+1B.)2x+y=7The slope line A is _The slope of line B is _Lines A and B are _

Answers

You have the following equation of two lines:

A) y = 2x + 1

B) 2x + y = 7

the general form of an equation of a line is given by:

y = mx + b

where m is the slope and b is the y-intercept.

The equation A is already written in the slope-intercep form. By comparing the equation with the general form you can notice that the slope is:

mA = 2

Next, you rewrite the equation B:

2x + y = 7 subtract 2x both sides

y = -2x + 7

by comparing with the general fom you have that the equation B has the following slope:

mB = -2

In order to determine if the lines are parallel,perpendicular, or neither, you calculate the quotien between the slopes of the lines.

mA/mB = 2/(-2) = -1

The quotient between the slopes is -1, this means that the lines are perpendicular

Answers

It is given that h(x)=fog(x) and h(x)=4(x+1)^2.

So it follows:

[tex]\text{fog(x)}=4(x+1)^2[/tex]

For option A, f(x)=x+1,g(x)=4x^2

So the value of fog(x) is given by:

[tex]f(g(x))=g(x)+1=4x^2+1[/tex]

So A is incorrect.

For option B, f(x)=(x+1)^2,g(x)=4x^2

So the value of fog(x) is given by:

[tex]f(g(x))=g(x)+1=(g(x)+1)^2=(4x^2+1)^2[/tex]

So B is incorrect.

For option C, f(x)=4x^2,g(x)=x+1

So the value of fog(x) is given by:

[tex]f(g(x))=4\lbrack g(x)\rbrack^2=4(x+1)^2[/tex]

So C is correct.

A projectile is launched from the ground at 128 feet per second and will hit the ground after a certain amount of time. It models the function g(x) = -16x2 + 128x, where x represents the time of the of the flight (in seconds) of the projectile. What is an appropriate domain for this model? 00 0

Answers

[tex]g=-16x^2+128x[/tex]

time can only take values ​​greater than or equal to zero, so the domain starts on 0

the las point of the domain is when the projectile hit the ground, this means when g=0

now we will replace g=0 o find the last value of the domain

[tex]\begin{gathered} g=0 \\ -16x^2+128x=0 \end{gathered}[/tex]

solve x to know the last time

[tex]\begin{gathered} 16x(-x+8)=0 \\ -x+8=\frac{0}{16x} \\ -x+8=0 \\ -x=-8 \\ x=8 \\ \end{gathered}[/tex]

Math answers and how you got the answer to solve

Answers

Hello there. To solve this question, we'll have to remember some properties about functions.

Given the functions:

[tex]\begin{gathered} f(x)=x^3 \\ g(x)=6x^2+11x-2 \end{gathered}[/tex]

We have to determine:

[tex]\begin{gathered} (f+g)(x) \\ (f-g)(x) \\ (fg)(x) \\ (ff)(x) \\ \left(\frac{f}{g}\right)(x) \\ \left(\frac{g}{f}\right)(x) \end{gathered}[/tex]

And their domain.

Let's do each separately:

(f + g)(x)

In this case, this function is the same as adding f(x) and g(x):

[tex](f+g)(x)=f(x)+g(x)=x^3+6x^2+11x-2[/tex]

And as it is a polynomial function, it has no holes or asymptotes, therefore its domain is all the real line. We write:

(f - g)(x)

In the same sense, it is equal to the difference between f and g:

[tex](f-g)(x)=f(x)-g(x)=x^3-(6x^2+11x-2)=x^3-6x^2-11x+2[/tex]

Again, as it is a polynomial function, its domain is all the real line, just as before.

(fg)(x)

In this case, it is the same as the product of f and g:

[tex](fg)(x)=f(x)\cdot g(x)=x^3\cdot(6x^2+11x-2)=6x^5+11x^4-2x^3[/tex]

Once again, its domain is all the real line.

(ff)(x)

In this case, it is the product of f and itself:

[tex](ff)(x)=f(x)\cdot f(x)=x^3\cdot x^3=x^6[/tex]

As before, its domain is entire real line.

(f/g)(x)

In this case, it is the quotient between f and g, respectively:

[tex]\mleft(\frac{f}{g}\mright)(x)=\frac{x^3}{6x^2+11x-2}[/tex]

But in this case, its domain is not the entire real line. We have to get rid of the holes and vertical asymptotes of the function.

This function has no holes, since we cannot simplify any terms in the fraction, but it has at least two vertical asymptotes (that we'll find by taking the roots of the denominator).

In fact, the name vertical asymptote stands for the values of x in which the function would not exist (its limit goes to either infinity, -infinity or would not exist).

These roots are given by:

[tex]6x^2+11x-2=0[/tex]

Using the quadratic formula, we get:

[tex]\begin{gathered} x=\frac{-11\pm\sqrt[]{11^2-4\cdot6\cdot(-2)}}{2\cdot6}=\frac{-11\pm\sqrt[]{121+48}}{12}=\frac{-11\pm\sqrt[]{169}}{12} \\ \Rightarrow x=\frac{-11\pm13}{12} \\ \Rightarrow x_1=\frac{-11+13}{12}=\frac{2}{12}=\frac{1}{6} \\ x_2=\frac{-11-13}{12}=\frac{-24}{12}=-2 \end{gathered}[/tex]

The roots are 1/6 and -2. They are the vertical asymptotes of the function.

The domain of (f/g)(x) is then given by subtracting these values from the real line:

Or also in interval notation:

We do the same to (g/f)(x):

It is equal to the quotient between g and f, respectively, thus

[tex]\left(\frac{g}{f}\right)(x)=\frac{g(x)}{f(x)}=\frac{6x^2+11x-2}{x^3}[/tex]

And again in this case, we have no holes, but we do have a vertical asymptote.

Taking the roots of the denominator:

[tex]x^3=0[/tex]

The only solution to it is:

[tex]x=0[/tex]

And the domain is then given by:

Answers

Javier has purchased the laptop 57 days ago, and the store's policy for items returned within 60 days is a 90% refund of the original price. Since Javier returned the item today, which is exactly 57 days right after his purchase, the 90% refund will be made. To solve the refunded price, we just multiply the cost of the laptop by the percent refund. We have ($385) x (90%) = $346.5.

Hence, Javier gets $346.5 as a refund on returning the laptop today.

500 books were sold the first day it went on sale. 150 books were sold each day after that. Write an equation to represent the total number of books sold. How many books were sold after 50 days?

Answers

Let x represent the number of days after release and y represent the number of books sold.

The first day there were 500 books sold, after that, 150 books were solf each passing day.

This means that for the first day y=500 ann each passing day 150 books were added, the equation is:

y=500+150x

Using this equation you have to calculate the number of books solf after x=50 days.

To do so replace in the equation above:

y=500+150*50

y=8000

After 50 days 8000 books were sold
