Tom spent $17,886 for a new car. The car will depreciate 11% each year. What will the car be worth after 11 years? Round your answer to the nearest cent. Do not include the dollar sign in your answer.

495.62

Step-by-step explanation:

Given data

Amount=$17,886

Rate = 11%

TIme= 11 years

Let us apply the compounding expression

A=P(1-r)^tThe negative sign is due to decreasing value

substitute

A= 1786(1-0.11)^11

A=1786(0.89)^11

A=1786*0.2775

A=495.615

Hence the approximate Amount will be 495.62

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
