state restrictions for the given equation below

The price range of the Chevrolet HHR retro will be $14,500.

The range of the data is defined as the difference between the maximum value of data and the minimum value of the data.

The given data as:

$8,500, $8,500, $8,500, $9,900, $10,800, 10,800, 11,000, 12,500, $12,500, $13,000, 13,000, $14,500, and $23,000

According to the given information, the required solution would be as:

The maximum value of data = $23,000

The minimum value of data = $8,500

The range of the data = The maximum value of data - The minimum value of data

Substitute the values in the above formula,

The range of the data = 23,000 - 8,500

Apply the subtraction operation to get the answer

The range of the data = 14,500

Therefore, the price range of the Chevrolet HHR retro will be $14,500.

The domain and range of the relation shown in the table include the following: A. domain:{−3, −1, 2, 4}, range:{0, 2, 4}.

In Mathematics, a domain can be defined as the set of all real numbers for which a particular function or relation is defined.

This ultimately implies that, a domain is the set of all possible input values (x-values) to a relation, and the domain of a graph comprises all the input values which are located on the x-coordinate from the least to the greatest.

Additionally, a range is the set of all real numbers that is associated with the elements of a domain i.e all of the y-values shown on the y-coordinate of the graph of a relation, from the least to the greatest.

By critically observing the table of this relation shown, we can reasonably infer and logically deduce the following:

Domain = {−3, −1, 2, 4}.

Range = {0, 2, 4}.

The transformation rule used to transform Triangle PQR to P'Q'R' is; (x, y) → (⁵/₂x, ⁵/₂y)

We are given from the question that the triangle P'Q'R' was transformed from the triangle PQR.

We see from the image that the coordinates of the original triangle PQR are;

P(-1, 1)

Q(2, 0)

R(-1, -2)

We also see that the coordinates of the transformed triangle P'Q'R' are;

P(-5/2, 5/2)

Q(5, 0)

R(-5/2, -5)

The option that shows the equation for the line in the graph is

A graph is a pictorial representation of data. The graph shows a linear function which will be written in the slope intercept form  form as

y = mx + c

where

m = slope

c = intercept

x = input variables

y = output variables

calculation of slope

The points used for the slope is gotten from the graph as B(-5. 5)  (-2, -4)

m = (y₂ - y₁) / (x₂ - x₁)

substituting the values

= ( -4 - 5 ) / ( -2 - -5 )

= -9 / -2 + 5

= -9 / 3

= -3

y intercept, c

this is a point where the graph cuts the y axis

c = -10

hence the equation is written using y = mx + c and substituting the values

y = -3x - 10

Answer:

4.5 miles

Step-by-step explanation:

0.5 of a mile per 1/9 of an hour.

rate x time=distance and you need to find distance for one hour not 1/9 so multiply it by 9 so

0.5*9=4.5, 1/9*9=1

rate   time   distance

4.5  *    1   =  d

4.5*1=d

4.5=d

so the distance traveled in one hour is 4.5 miles

Answer:

4.5 miles

Step-by-step explanation:

Given:

Let x be the distance Julia rides in one hour.

Create an equivalent ratio of miles to hours:

[tex]\implies \dfrac{1}{2}:\dfrac{1}{9}=x:1[/tex]

[tex]\implies \dfrac{\frac{1}{2}}{\frac{1}{9}}=\dfrac{x}{1}[/tex]

[tex]\implies \dfrac{1}{2}\times \dfrac{9}{1}}=x[/tex]

[tex]\implies \dfrac{9}{2}=x[/tex]

[tex]\implies x=4.5[/tex]

Therefore, Julia rides 4.5 miles in one hour.

The length of the base edge of the pyramid is 1.71 feet

In order to find the total surface area, we will need to add up the areas of the base and the three other sides. SA=B+12(P×h), where B is the area of the base of the pyramid, P is the perimeter of the base, and h is the slant height of the pyramid.

If l is the length of the square base and h is the height of the pyramid, then h =2/3l

from the formula, SA= B+12(P×h)

the perimeter of a square is 4l

the base area of square is l^2

therefore 96= l^2+ 12(4l×2/3l)

96= l^2+ 12×8/3l^2

96=l^2+32l^2

96= 33l^2

divide both sides by 33

l^2= 96/33

l=√2.91

l=1.71 feet

therefore the length of the base edge is 1.71 feet

The compound interest earned by Evelyn in one year is $9.

Evelyn has a bank account. She deposited $90 in her account. She earns 10% interest on her deposited money. The interest earned is compounded annually. We need to calculate the interest earned by her in one year, to the nearest cent.

We need to calculate the compound interest. The formula is given below.

B = p(1 + r)^t

The variables 'B', 'p', 't', and 'r' represent the final amount, the initial amount, the time duration, and the rate of interest, respectively.

B = $90(1 + 0.1)^1

B = $90*1.1

B = $99

The final amount in her bank account after one year is $99. The interest earned is the difference between the final and the initial amount. Let the variable 'I' represent the interest earned.

I = B - p

I = $99 - $90

I = $9

The given function are

r(x) = 2 - x²    and     w(x) = x - 2

(w*r)(x) can be obtained by multiplying the both function together

So, (w*r)(x) = w(x) * r(x) = (x-2)*(2-x²)

(w*r)(x) = x (2-x²) - 2(2-x²)

           = 2x - x³ - 4 + 2x²

∴ (w*r)(x) = -x³ + 2x² + 2x - 4

It is a polynomial function with a domain equal to R

The range of (w*r)(x) can be obtained by graphing the function

To graph (w*r)(x), we need to make a table between x and (w*r)(x)
