Hi there I am having trouble with these. I know its a lot to ask :/ sorry
any help is appreciated.** Please include steps if possible**, thank you-Natalia
Use the 1-1 property of exponential functions to solve the given equation.
1. 5^1-x=125
2. 3^x+2=81/3x
Determine the balance B if a principal of P dollars is deposited in an account for t years at an annual rate of interest r compounded n times per year. Give the answers to the nearest cent.
P=$2500, t=5, r=8%
a. n=1
b. n=4
c. n=12
d. n=365
e. compounded continuously
1. Grandparents wish to determine whether the CD they purchased will pay for their new grandchild's college education. The CD is 5000 and the interest rate is 8%. Assuming that 1 year at their alma matter currently costs $15000 and the amount is likely to increase an average of 5% per year. Use the formula for interest compound annually to estimate what 1 year of college will cost in 18 years.
