Answer:

$19219.

Step-by-step explanation:

We have been given that Alex purchased a new car for 28,000. The cars value depreciates 7.25% each year.

We will use exponential decay function to solve our given problem.

y=a\cdot b^x, where,

a = Initial value,

b = For decay b is in form (1-r), where r represents decay rate in decimal form.

Let us convert our given rate in decimal form.

7.25\%=\frac{7.25}{100}=0.0725

Upon substituting our given values in above formula we will get,

y=\$28,000\cdot(1-0.0725)^5

y=\$28,000\cdot(0.9275)^5

y=\$28,000\cdot 0.686387856528418

y=\$19218.8599\approx \$19219

Therefore, the value of car 5 years after it is purchased will be $19219.

If depreciation is 7.25% per year, then the common factor is (1-0.0725), or 0.9275.

Thus, the car's value after 5 years will be:

V = $28000(0.9275)^5 = $28000(0.6864) = $19218.86, or (to the nearest dollar) $19218 (answer)

When 80% of a is added to the number, the result is 252. What is the number
wariber [46]
Use the equation .8x + x = 252
x is the number, and .8 is the decimal equivalent of 80%.

1.8x = 252

x = 140

Anyone know? <br> A. 99 <br> B. 100 <br> C. 121<br> D. Cannot be determined
Verizon [17]

Since, it is given that the pentagon ABCDE is congruent to pentagon FGHIJ.

By being congruent, the corresponding angles and sides are equal.

Therefore, \angle A = \angle F, \angle B = \angle G, \angle C = \angle H, \angle D= \angle I, \angle E = \angle J.

By using \angle A = \angle F

So, 100^\circ = \angle 1

Therefore, the measure of angle 1 is 100 degrees.

So, Option B is the correct answer.
