Answer:

First one: C. Second One:C.

Step-by-step explanation:

Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years?

a) $13,935.76

b) $12,874.57

c) $13,792.99

To solve this this is an exponential function. The price started at $23,000 and depreciates at 12% so the equation is f(x) = (23,0000)(1-0.12)^4. When calculated results with 13792.99328 which is C.

A rare coin is currently worth $450. The value of the coin increases 4% each year. Determine the value of the coin after 7 years.

a) $613.98

b) $546.78

c) $592.17

To solve this this is also an exponential function. The price started at $450 and  the coin increases 4% each year so the equation is f(x) = (450)(1+0.04)^7. When calculated results with 592.169300656 which is c.

9. Find the length of a base of a triangle with<br>an Area of 100 and a height of 25.​
liraira [26]

Answer:

8 (units)

Step-by-step explanation:

The formula to find the area of a triangle is A = 1/2(b*h). Since we know the area already, we can substitute that value in to calculate the answer backwards.

Plug in the numbers known:

A = 100

h = 25

Equation: 100 = 1/2(b*25)

Now solve:

100 = 1/2(b*25)

200 = b * 25

<em>8 = b</em>

So, the answer to your question is 8 (units).

Hope this helps!

The sum of 8 times a number 4 and 5 equals .
Tema [17]

Answer:

37

Step-by-step explanation:

This may look like a complicated problem but it's some simple analyzing of the problem to get the job done:

"The sum" tells that we are going to be adding together the next two phrases separated by "and"s.

That is "8 times a number 4"  <em>and</em>  "5"

Therefore, we need to add 2 groups:

(8*4) + (5)

Now, we simply use PEMDAS (or GEMDAS) to solve the expression:

(8*4) + (5)

= (32) + (5)

= 32 + 5

= <u>37</u>
