Determine the amount needed such that when it comes time for retirement, an individual can make semiannual withdrawals in the am
Alex787 [66]

Answer:

--------------------------------------------------------------------------------------------------------------

$535,528.03

Since the semiannual withdrawals will be made for 35 years, the annuity will have two payments per year.

You may use a financial calculator to calculate the balance that will match the present value of your annuity distributions when you retire. The following are the inputs:

N = 35*2 = 70 semi-annual withdrawals total time

I/Y = 4.5 percent /2 = 2.25 percent semi-annual interest rate

FV = 0 (future value) (use 0 in annuity if not given)

PMT = 15,265; semi-annual payment

Enter the functions to find PV: CPT PV = 535,528.026

As a result, the person will need $535,528.03 in cash.

Solve the following exponential equations.<br> 2(4^x )+ 4^(x+1 )= 342
Cloud [144]

Answer:

  x ≈ 2.91644500708

Step-by-step explanation:

The equation can be simplified to ...

  2(4^x) +4(4^x) = 342

  6(4^x) = 342

  4^x = 57

Taking logarithms, we get ...

  x = log₄(57) = log(57)/log(4)

  x ≈ 2.91644500708

A=3.14r^2 and d=12 A=?
zvonat [6]

\huge\boxed{113.04}

Diameter (d) is equal to twice the radius (r). So, find the radius by dividing \frac{12}{2}. The radius, or r, is 6.

Substitute in the value. A=3.14*6^2

Follow the order of operations and solve the exponent first. A=3.14*36

Multiply. A=\boxed{113.04}
