1. Given the equation model
F(x) = 62 + 35 log(x) - 4
x represents a girl's age from 5 to 15 years.
F(x) represents the percentage of adult height.
Determine approximately what percentage of her adult height would the girl be at age 13?
2. Use the compound interest formula
A = p(1+r/n)^(nt)
to solve the problem. Find the accumulated value of an investment of 20,000 for 5 years at interest rate 60%, if the money is
a. compounded semiannually,
b. compounded quarterly, and
c. compounded monthly.
1. Substituting the value for x, we have:
F(13) = 62 + 35 log(13) - 4
F(13) = 62 + 38.99 - 4
F(13) = 96.99
2. a. Using the ...
