For each one-year period after a car was purchased, its value at the end of the year was 17% less than its value at the beginning of the year. State whether the value of the car as a function of time after it was purchased is best modeled with a linear function, a quadratic function, or an exponential function and explain why. Enter your answer and your explanation in the space provided. If the value of the car 2 years after it was purchased is $17,842.51, what was the value of the car when it was purchased?
Answer:
The value of the car as a function of time after it was purchased is best modeled with an exponential function.
The Value of car when it is purchased = $25,900
Step-by-step explanation:
As given,
The value at the end of the year was 17% less than its value at the beginning of the year.
⇒ value at the end of the year = (100% - 17% ) = 83% of value at the beginning of the year.
Now,
Let the Value of car when it is purchased = x
So,
Price at the end of 1 year = 83% of x = 0.83x
Price at the end of 2 year = 83% of 0.83 x = (0.83)² x
Price at the end of 2 year = 83% of (0.83)² x = (0.83)³ x
and so on
Price at the end of n years = (0.83)ⁿ x
∴ we get
The value of the car as a function of time after it was purchased is best modeled with an exponential function.
Now,
Value of car after 2 year = (0.83)² x = $17,842.51
⇒0.6889x = $17,842.51
⇒x = [tex]\frac{17,842.51}{0.6889}[/tex] = $25,900
∴ we get
The Value of car when it is purchased = x = $25,900

The two prisms below are similar. What is the value of x?
10
15
A. 1
B. 15
C. 10
D. 5
The correct option is D, the value of the missing side x is 5.
How to find the value of x?If the two prism are similar, then there is a scale factor that when multiplied by the dimensions of the blue prism, we get the dimensions of the green one.
If that scale is k, then we can write:
3k = 15
Solving for k:
k = 15/3
k = 5
Now, the correspondent side to the one that measures x, has a measure of 1 unit (in the blue prism), then the value of x is:
1*k = x
1*5 = x
5 = x
The correct option is D.

Lucas has a 39-foot-long rope. He uses all the rope to outline this T-shape in his backyard. All the angles in the figure are right angles. (Work out and answer number 13 and number 14, please.)
Answer:
Step-by-step explanation:
The area of a shape is the amount of space it can occupy, while the perimeter is the sum of its sides.
The value of x is 7.5 ftThe area of the shape is 57 square feetGiven that:
[tex]P = 39[/tex] --- the perimeter of the shape
The value of x
The perimeter is the sum of all sides.
So, we have:
[tex]P = x + x + 3.5 + 3.5 + 3 + 3 + 9 + (9 - 3.5 - 3.5)[/tex]
Substitute 39 for P
[tex]x + x + 3.5 + 3.5 + 3 + 3 + 9 + (9 - 3.5 - 3.5) = 39[/tex]
[tex]2x + 24 = 39[/tex]
Collect like terms
[tex]2x = -24 + 39[/tex]
[tex]2x = 15[/tex]
Divide through by 2
[tex]x = 7.5[/tex]
The area of the shape
The shape can be divided into two rectangles
A 9ft by 3ft rectangleA (9 - 3.5 - 3.5)ft by x ft rectangleSo, the area of the shape is:
[tex]Area = 9ft \times 3ft + (9 - 3.5 - 3.5)ft \times x ft[/tex]
[tex]Area = 27ft^2 + 2ft \times x ft[/tex]
Substitute [tex]x = 7.5[/tex]
[tex]Area = 27ft^2 + 2ft \times 15 ft[/tex]
[tex]Area = 27ft^2 + 30 ft^2[/tex]
[tex]Area = 57 ft^2[/tex]
Hence, the area of the shape is 57 square feet.

What are the coordinates of the point in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6? PLS HELP!!!!
Answer:
The coordinates of the point X:
(x, y) = (-1, -7)Step-by-step explanation:
Let X be the point.
As the point X is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6
i.e.
[tex]\left(x_1,\:y_1\right)\:=\:\left(-2,-8\right)[/tex]
[tex]\left(x_2,\:y_2\right)=\left(5,-1\right)[/tex]
Rise = y₂ - y₁
[tex]= -1 - (-8)[/tex]
[tex]= -1 + 8[/tex]
[tex]= 7[/tex]
Run = x₂ - x₁
[tex]= 5 - (-2)[/tex]
[tex]= 5 + 2[/tex]
[tex]= 7[/tex]
1 : 6 ratio means the point X lies at
[tex]\frac{1}{6+1}=\frac{1}{7}=14\%[/tex]
Thus,
rise for X [tex]=\:7\:\times \:14\%=1[/tex]
run for X [tex]=\:7\:\times \:14\%=1[/tex]
Thus, coordinates of X will be:
[tex]x = -2 + 1 = -1[/tex]
[tex]y = -8 + 1 = -7[/tex]
Therefore, we conclude that:
The coordinates of the point X:
(x, y) = (-1, -7)The point (-1, -7) divide the segment from (-2,-8) to (5,-1). in the ratio 1:6.
What is distance?If a point O(x, y) divides the line segment AB in the ratio of n:m, where the endpoints of the line is A(x₁, y₁) and B(x₂. y₂), the point O is at:
[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]
Given the ratio 1:6, let O(x, y) divide the segment from (-2,-8) to (5,-1). Hence:
[tex]x=\frac{1}{1+6}(5-(-2))+(-2)=-1\\\\y=\frac{1}{1+6}(-1-(-8))+(-8)=-7[/tex]
O = (-1, -7)
The point (-1, -7) divide the segment from (-2,-8) to (5,-1) in the ratio 1:6.

Write a ratio, in the simplest form and a percent for the shaded area (there's a 5x4 box and 6 cubes are shaded)
Answer:
[tex]\%Percent = 30 \%[/tex]
Step-by-step explanation:
Given
[tex]Shaded = 6\ cubes[/tex]
[tex]Box = 5\ x\ 4[/tex]
Required
Determine the percentage of the shaded cubes
First, we calculate the number of boxes:
[tex]Box = 5\ x\ 4[/tex]
Express as multiplication
[tex]Box = 5\ *\ 4[/tex]
[tex]Box = 20[/tex]
This implies that there are 20 cubes in the box.
The percentage of the shaded cubes is:
[tex]\%Percent = \frac{Shaded}{Box} * 100\%[/tex]
[tex]\%Percent = \frac{6}{20} * 100\%[/tex]
[tex]\%Percent = \frac{6* 100}{20} \%[/tex]
[tex]\%Percent = \frac{600}{20} \%[/tex]
[tex]\%Percent = 30 \%[/tex]
30% were shaded
