The function f(t)= 15000(1.08)^t models the value of an investment t years from now. what is the meaning of the value of f(10) a the value of the investment 10 years ago b the value of the investment in 10 years c the initial value of the investment d the interest rate the investment earns

in the f(t) = 15000(1.08)ᵗ, which is a form of a compounded interest formula, t = years, so

f(t) = 15000(1.08)¹⁰ , is the value of it when t = 10, after 10 years.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
