Answer:

Circ = 2 x pi x r

28.3 = 2 x 3.14 x r

r = 28.3 / (2 x 3.14) = 4.51 cm

r = 4.5 cm

Answer:

a. 0.81

b. v = 28000(0.81^n)

c. 2757.36

Step-by-step explanation:

a. The growth factor is 1 more than the growth rate. Here, the growth rate is -19% (per year), so the growth factor, the multiplier, is ...

1 -0.19 = 0.81

b. The equation sets value equal to the original value multiplied by the growth factor to the power of the number of years:

value = (original value) × (growth factor)^n

v = 28000(0.81^n)

c. For n=11, this is ...

v = 28000(0.81^11) ≈ 2757.36

The value of the truck after 11 years is about $2757.
