Part a)

Price of car is $32,000 and the value of Car is depreciating at a rate of 8.5% per year. This means the worth of car is decreasing. Hence it is a decay.

Part b)
Worth of car in 5 years.

Current Price = P = $32000
Decay rate = r = 0.085
Time = t = 5 years

Formula to be used:

A=P(1-r)^{t} \\  \\ 
A=32000(1-0.085)^{5} \\  \\ 
A=20523.69

This means, the worth of car after 5 years will be reduced to $20,523.69

Part c)
When the car will be worth half of its original amount.

Half amount = $16,000
Using the values in above formula, we get

16000=32000(1-0.085)t^{2} \\  \\ 
0.5=(0.915)^{t} \\  \\ 
t=7.8

This means, after 7.8 years the car be worth half of what Carson paid

Determine the intercepts of the line.<br> y=5x-13<br><br> Y-Intercept ( , )<br> X-Intercept ( , )
Arte-miy333 [17]

Answer:

Y-intercept is (0, -13)

X-intercept is at (13/5, 0)

Step-by-step explanation:

When it's in this form, y = mx + b, you automatically know what the y-intercept is (b).

So the y-intercept is (0, -13)

To algebraically find this, you'd plug in a 0 for x, since the y intercept is when it crosses the y-axis, which is located at x = 0.

To find the x intercept, you'd do the opposite of the y-intercept, which is plugging in a 0 for y and solving for x. The x-axis is located at y = 0.

0 = 5x - 13

13 = 5x

x = 13/5

The x-intercept is at (13/5, 0)

I hope this helped!

What element in the domain has image 7 in the function f(x) = x²– 2?<br><br>a. 3 b) 9 c) -1 d) 4
blagie [28]

Here,

f(x) = 7

x = ?

Now,

f(x) = x^2 - 2

or, 7 = x^2 - 2

or, 7 + 2 = x^2

or, x^2 = 9

◆ x = 3

a) 3

I hope it's help you...
