Suppose the value of a car depreciates 8% every year. To the nearest dollar, what will a car that cost $23,995 be worth after 5

Vanyuwa [196]

Answer:

The car will worth $15815 after 5 years.

Step-by-step explanation:

The formula is: $A=P(1+r)^t$ , where P = Initial cost, A = Final cost, r = Rate of change in cost per year and t = Number of years.

Here, $P= 23995, t= 5$

and $r= 8\%=0.08$

As here the value of the car depreciates every year, so we need to plug the value of $r$ as negative. So, $r=-0.08$

Now plugging the above values into the formula, we will get.....

$A=23995(1-0.08)^5\\ \\ A=23995(0.92)^5\\ \\ A=15814.6611... \approx 15815$

(Rounded to the nearest dollar)

So, the car will worth $15815 after 5 years.

The area of the trapezoid is 108 in2. What is the height of the trapezoid?

dezoksy [38]

The area of the trapezoid is given by the formula A= (a+b)/ 2 * h

in this question a= 8, b= 10, A= 108 inches², and h is what we have to find, substitute what we have got into the formula and you will have:

108= (8+10) /2 *h

108= 9 *h

h= 108/9

h= 12 inches
