Shota invests $2000 in a certificate of deposit that earns 2% in interest each year

write a function that gives the total value V(t), in dollars, of the investment t years from now

Step-by-step explanation:

To solve the problem, we use the compound interest formula.

The formula that gives the total value V(t) of the investment after t years is:

where

is the initial value of the investment

r is the interest rate

t is the time (in years)

V(t) is the value of the investment after t years

In this problem:

is the initial investment

is the interest rate

Substituting, we find the final expression for this problem:

which can be reduced to

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
