$36000. For every year after it is purchased, the car loses 17% of its value due to depreciation. What is the value of the car after 64 months? find in exponential function grade 11 math

Step-by-step explanation:

The expression for depreciation is

V=C(1-r)^t ,

where V is the value of the car after t years,

C is the original cost, and

r the rate of depreciation. If a car

given

C=$36000

r=17%= 0.17

t in years 64/12= 5.33years

Substituting to the formula we have

V=36000(1-0.17)^5.33

V=36000(0.83)^5.33

V=36000*0.370

V=13,320

the value will be $13,320

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
