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.) y = 18(1.15)x

Answer:

y = 18 * 1.15^x

Step-by-step explanation:

Given

a = 18 --- initial

r =15\% -- rate

Value after a year = $20.70

Required

Expression to calculate its value after y years

This is calculated using:

y = ab^x

Where

b=1 +r

Substitute r =15\% in b=1 +r

b = 1 + 15\%

b = 1 + 0.15

b = 1.15

Substitute b = 1.15 and a = 18 in y = ab^x

y = 18 * 1.15^x

Answer:

1.  V = 94 meters cubed

2. V = 8 feet cubed

3.  V = 57 inches cubed

Step-by-step explanation:

The volume of a cone is 1/3 the volume of a cylinder. So all you need to do is plug the numbers into the formula for the volume of a cylinder and then you have the answer.

The formula for a cylinder is V= (3.14 or pi) * radius squared * height

The formula for a cone is V= (3.14 or pi) * radius squared * height * 1/3

So here you go.....

1. V= 3.14 x 9 x 10 x 1/3                V = 94 meters cubed

2. V= 3.14 x 4 x 2 x 1/3                   V = 8 feet cubed

3. V = 3.14 x 9 x 6 x 1/3                  V = 57 inches cubed

Please give me brainiest!

STUV~CBED.<br> What is the similarity ratio of STUV to CBED?
ASHA 777 [7]

The similarity ratio of STUV to CBED is 0.5

<h3>How to determine the similarity ratio of STUV to CBED?</h3>

For the shapes to have a similarity ratio, it means that:

The shapes are similar (not necessarily congruent)

From the diagram, the following sides are corresponding sides

ST and CB

Where

ST = 2

CB = 1

The similarity ratio of STUV to CBED is calculated as:

Ratio = CB/ST

Substitute the known values in the above equation

Ratio =1/2

Evaluate

Ratio = 0.5

Hence, the similarity ratio of STUV to CBED is 0.5
