Compound interest is given by the formula A = P ( 1 + r ) t . Where A is the balance of the account after t years, and P is the

starting principal invested at an annual percentage rate of r , expressed as a decimal. Alex is investing money into a savings account that pays 2% interest compounded annually, and plans to leave it there for 15 years. Determine what Alex needs to deposit now in order to have a balance of at least $40,000 in his savings account after 15 years. Alex will have to invest a minimum of $ now in order to have a balance of at least $40,000 in his savings account after 15 years. Round your answer to the nearest dollar.

If FE measures 20 centimeters, the approximate area of circle B is what
MAXImum [283]

If FE measures 20 cm, then the area is 314 cm², if BE measure 3.5 cm, then the area is 38.5 cm², if AB measures 11 cm, then the area is 380 cm² and is EF measures 12 cm, then the area is 113 cm².

Area of a circle:

A = π r²

r = 1 /2 of diameter.

FE is the diameter

r = 20 / 2

r = 10 cm

Area of circle using FE:

A =  π ( 10 )² = π × 100 = 314 cm²

BE is a radius:

Area = π × 3.5² = π × 12.25 = 38.465

A = 38.5 cm²

AB is a radius:

Area = π × 11²
A = π × 121

A = 379.94 = 380 cm²

EF is a diameter:

r = 12 / 2 = 6 cm

Area = π × 6²

A = π × 36

A = 113.04 = 113 cm²

Therefore, if FE measures 20 cm, then the area is 314 cm², if BE measure 3.5 cm, then the area is 38.5 cm², if AB measures 11 cm, then the area is 380 cm² and is EF measures 12 cm, then the area is 113 cm².

sesenic [268]

First, find a common denominator (the bottom number) Then add the tops as usual. Four and five have a common denominator of 20 so: 8/20+5/20=13/20
