Answer:

You will pay $1,300 in interest.

The final price of the car is of $14,300

Step-by-step explanation:

Simple interest formula:

$I=P\ast r\ast t$

In which:

I is the interest

P is the principal(initial value of the investment, amount borrowed,...)

r is the interest rate, as a decimal

t is the time, in years.

In this question:

Borrow $13,000, so P = 13000

4 years, so t = 4

Interest rate of 2.5%, so r = 0.025

$I=13000\ast0.025\ast4=1300$

You will pay $1,300 in interest.

Final price of the car:

Principal plus interest.

$T=P+I=13000+1300=14300$

The final price of the car is of $14,300

The 13-foot string is arranged into a rectangle. Let L denote the length of the rectangle,

soldi70 [24.7K]

The expressions for the width, W, and area, A, of the rectangle in terms of L are:

W = $\frac{13}{2}$ - L
A = $\frac{13L - L^{2} }{2}$

The expression for the perimeter of a rectangle is given as:

P = 2(L + W)

where L is its length and W its width

a. Given that the perimeter of the rectangle is 13 feet, then;

13 = 2(L + W)

divide through by 2

$\frac{13}{2}$ = L + W

So that;

W = $\frac{13}{2}$ - L

The required formula for the width as a function of L is: W = $\frac{13}{2}$ - L

b. Area of a rectangle can be expressed as;

A = L * W

substitute the expression for width in that of area to have

A = L * ( $\frac{13}{2}$ - L)

= $\frac{13}{2}$ L - $L^{2}$

A = $\frac{13L - L^{2} }{2}$

The expression for the area A is: A = $\frac{13L - L^{2} }{2}$
