a limited-edition poster increases in value each year with an initial value of $18. after 1 year and an increase of 15% per year, the poster is worth $20.70. which equation can be used to find the value, y, after x years? (round money values to the nearest penny.)
which option?
y = 18(1.15)x
y = 18(0.15)x
y = 20.7(1.15)x
y = 20.7(0.15)x

Equation used to find the value, y, after x years is y = 18(1.15)^x, Option A is correct.

Step-by-step explanation:

Initial value of poster = $ 18

After 1 year amount of increase = $ 20.70

Rate = 15% = 0.15

Which equation can be used to find the value, y, after x years?

Future Value = y

Years = x

y = 18(1.15)^x

is the correct answer.

After 1 year the price is $20.7

Checking by putting in equation

y = 18(1.15)^1

y = 20.7

Equation used to find the value, y, after x years is y = 18(1.15)^x

So, Option A is correct.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
