DOES ANYONE KNOW HOW TO DO THIS? DUE AT 11 TONIGHT PLS HELP!

High demand cars that are also in low supply tend to retain their value better than other cars. The data in the table are for a car that won a resale value award.

Enter a function to represent the car's value over time, assuming that the car's value is linear for the first 5 years.


According to your model, how much did the car's value drop the day it was purchased and driven off the lot?




Do you think the linear model would still be useful after 10 years? Explain.


uppose you used months instead of years to write a function. How would your model change

Answer 1

Answer:

No because its -10 per year so after 10 years the car value will go below zero which makes it useless

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Given the table of values where it represents the relationship between the change in value of a car and number of years.

Slope:

Before we can establish the linear equation, we need to determine its slope by using two ordered pairs from the table.  

Let (x₁, y₁) = (1, 84)

     (x₂, y₂) = (3, 64)

Substitute these values into the following slope formula:

m = (y₂ - y₁)/(x₂ - x₁)

m = (64 - 84)/(3 - 1)

m = -20/2

m = -10

Therefore, the slope of the linear function is -10.

1. Enter a function to represent the car's value over time, assuming that the car's value is linear for the first 5 years.

Assuming that the car's depreciation in value is linear for the first 5 years, then we can establish the following function:

Next, using one of the given ordered pairs from the table, (1, 84), and the slope, m = -10, substitute these values into the slope-intercept form to solve for the value of the car at x = 0 (the y-intercept, b ):    

84 = -10(1) + b

84 = -10 + b

Add 10 to both sides to isolate b:

84 + 10 = -10 + 10 + b

94 = b

Therefore, the linear function is f(x) = -10x + 94.

To verify whether this is the correct function to represent the given linear model, substitute the values for year 5, where the car's value is at 44%:

f(5) = -10(5) + 94

f(5) = -50 + 94

f(5) = 44  ⇒ This matches the value from the given table, where it implies that at year 5, the value of the car is 44%.           

2. According to your model, how much did the car's value drop the day it was purchased and driven off the lot?

Since the car's value is expressed in percentage (%), then it means that at year = 0, the car's value is 100%.  The value of the car in year 1 is 84%.

Therefore, the car's value will decrease by 16% from the day it was purchased (at year = 0) through year 1.    

To determine the value of the car the day it was purchased and driven off the lot:

Let x = 1 out of 365 days = 1/365 = 0.0027

f(0.0027) = -10(0.0027) + 94

f(0.0027) = -10(0.0027) + 94

f(0.0027) = -0.027 + 94

f(0.0027) = 93.973

The car's value at Day 1 is 93.97%, which means that it decreased by 6%.              

3. Do you think the linear model would still be useful after 10 years? Explain.

In order to determine whether the linear model would still be useful after 10 years, let x = 10:

f(x) = -10x + 94

f(10) = -10(10) + 94

f(10) = -100 + 94

f(10) = -100 + 94

f(10) = -6

The value of the car by the 10th year will be -6%, implying that it is no longer useful by year 10.  The linear model is only useful up to the 9th year:

f(9) = -10(9) + 94

f(9) = -90 + 94

f(9) = 4 ⇒ The car's value by the 9th year is 4%.

4. Suppose you used months instead of years to write a function. How would your model change?

Since in the original function, x represents the number of years, and there are 12 months in a year:

Let 12x = 12 months × 1 year

Substitute 12x as an input into the original function:

f(x) = -10x + 94

f(x) = -10(12x) + 94

f(x) = -120x + 94 ⇒ This represents the function that models linear relationship between the percentage value of a car relative to the number of months that the car is driven.

Answer:

Cleo is: 25 years old

Range of their ages: 7 years

Step-by-step explanation:

Supposing that they are all around roughly the same age, say, Ahmed was 18 and Beth was 20. The mean/average, is taking both ages, and dividing it by how many people there were. Which was just two. So, 18+20=38. 38/2 gets you 19. To get Cleo's age, we would do,

18+20+ Cleo's age. to get a number, divide it by 3, and get 21. Saying that the mean/average is 21, he would definetly be older. So plug in ages. 24+20+18=62. 62/3 gets you 20.67. 25+20+18=63. 63/3 gets you 21. Therefore, he must be 25.

The range is calculated by subtracting the largest number, by the smallest number. And, given that the median, or, middle is 20, we can know that the previous answer is correct. 25-18 to get 7 as the range.

Answers

Answer:

Make me as brain liest plz

The perimeter of triangle DEF is; 30 cm

We are given dimensions of Triangle ABC as;

AB = 9 cmBC = 6 cmCA = 7.5 cm

Thus;

Perimeter of Triangle ABC = 9 + 6 + 7.5 = 22.5 cm

We are told that Triangle DEF is similar to Triangle ABC.

This means that the ratio of corresponding sides must be equal to the ratio of their perimeter.

Side EF corresponds to side BC. Thus;

Perimeter of Triangle DEF/22.5 = 8/6

Cross multiply to get;

Perimeter of Triangle DEF = (22.5 × 8)/6

Perimeter of Triangle DEF = 30 cm

Answers

Answer:

last year = 530570

this year = 424456

decreased plants = 530570-424456 = 106114

decreased percent = 106114÷530570×100%

= 20%

The missing length of the given triangle divided into two right-angled triangle is 24.

The ratio 60:36:x is a ratio of 2:1:x. This means that the ratio of the lengths of the three segments is 2:1:x. The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.

Here is the solution in more detail:

The ratio 60:36:x can be written as 2:1:x.

This means that the ratio of the lengths of the three segments is 2:1:x.

The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.

Therefore, the missing length is 24.

Find the measures of the interior angles of the triangle.

Answers

Answer:

∠ A = 59°, ∠ B = 48° , ∠ C = 73°

Step-by-step explanation:

The interior angles of a triangle sum to 180°

sum the 3 angles and equate to 180

x + x - 11 + 73 = 180

2x + 62 = 180 ( subtract 62 from both sides )

2x = 118 ( divide both sides by 2 )

x = 59

Then

∠ A = x = 59°

∠ B = x - 11 = 59 - 11 = 48°

∠ C = 73°

Answer:

<A = 149*

<B = 138*

<C = 73*

Step-by-step explanation:

There are 360* total inside a triangle.

We subtract 73 from 360 to find the combined number of both angles a and b.

360-73 equals 287, so we know that both angles a and b add up to equal 287.

Since angle a equals x and angle b equals x - 11, we would combine the two expressions to find x. When we find x, it will allow us to know what both angles a and b equals to. So we combine x and x- 11, set it equal to 287, and solve for x.

x + x - 11 = 2x-11.

287 = 2x - 11

(Add eleven to both sides)

298 = 2x (divide both sides by two)

X = 149

Since angle a equals x, we know that angle a Is 149*.

And since angle b is x - 11, we take 149, subtract it by 11, and we get 138.

Answers

It would be graph A if I did it correct

Answer:

B) Graph B

Step-by-step explanation:

The quadratic equation in vertex form is represented by: y = a(x - h)² + k, where:

(h, k) = vertex

x = h : axis of symmetry

a = indicates a reflection in the x-axis; it also determines the graph's vertical stretch or shrink.

a > 0  the graph opens up.a < 0: the graph opens down.

h =  indicates a horizontal translation.

k =  indicates a vertical translation.

Given the given quadratic equation, y = (x - 2)² - 16:

The vertex occurs at point, (2, -16), and a = 1. Since the value of a is positive, then it implies that the graph opens upward, and the vertex is its minimum point.  The axis of symmetry occurs at h = 2.

To determine another point to use as a reference (and also for graphing) is solving for the equation's y-intercept, which is the point where it crosses the y-axis (where x = 0).

Y-intercept: set x = 0:

y = (x - 2)² - 16

y = (0 - 2)² - 16

y = (-2)² - 16

y = 4 - 16

y = -12

Therefore, the y-intercept is (0, -12).

Therefore, the graph that matches these given descriptions is Graph B.    

Attached is the graphed quadratic equation where it shows the vertex, y-intercept, and the axis of symmetry.

Answer:

A

Step-by-step explanation:

We can calculate the equation of the lines based on two points. First line m:

y = ax +b

where a is the slope and b is the y-intercept. To find the slope we use the x and y of the points as:

a = [tex]a = \frac{y_1-y_2}{x_1-x_2} = \frac{4- -32}{2- -4} = \frac{36}{6} = 6.[/tex]

So:

y = 6x + b

we can find the y intercept by substituting the x and y for one of the points:

solving for b:

b=-32-(6)(-4)= -8.

So the equation is:

y = 6x - 8.

We can change it to:

y + 8 = 6x

8 = 6x - y.

So it’s (A).
