use the formula for compound interest: A= P (1+r/n) ^nt

If $8,000 is invested at 5 % annual interest compounded semiannually, how much will the investment be worth in 6 years?

Give your answer to the nearest dollar.

One of the complementary angles is 4 degrees mor than the other. find the angles (recall that complementary angles are angles whose sum is 90 degrees.) which of the following can not be used to solve the problem if x represents one of the angles? a. 2x-4=90 b. 2x+4=90 c. x+4=90

Solve the equation for b: a= (1/2)(b)(h)

The sum of two numbers is 0. twice the smaller number subtracted from 3 times the larger number is 10. let x represent the larger number and y represent the smaller number. what is the equation
