Answer:

option A

The base is e^-1

Step-by-step explanation:

Given in the question a function, f(x) = (1/e)^{x}

This function can also be write as.

f(x) =(e^{-1})^{x}

by using Negative Exponent Rule

x^{-n}=\frac{1}{x^{n}}

This says that negative exponents in the numerator get moved to the denominator and become positive exponents.

You deposit $2000 each year into an account earning 7% interest compounded annually. How much will you have in the account in 30
SVETLANKA909090 [29]

The amount that will be in the account after 30 years is $188,921.57.

<h3>How much would be in the account after 30 years?</h3>

When an amount is compounded annually, it means that once a year, the amount invested and the interest already accrued increases in value. Compound interest leads to a higher value of deposit when compared with simple interest, where only the amount deposited increases in value once a year.

The formula that can be used to determine the future value of the deposit in 30 years is : annuity factor x yearly deposit

Annuity factor = {[(1+r)^n] - 1} / r

Where:

  • r = interest rate
  • n = number of years

$2000 x [{(1.07^30) - 1} / 0.07] = $188,921.57
