    A = s² \[A = 5^\frac{ 2 }{ 5 }*5^\frac{ 2 }{ 5 }\] When you multiply numbers with the same base, add the exponents

    Samantha puts an initial $500 into a savings account. The account has a 4% annual compound interest rate. What is the function that best represents Samantha's account and how much does she have in savings after 5 years? Round your answer to the nearest dollar. Hint: Use the formula, f(x) = P(1 + r)x. f(x) = 500(1.4)x, $2,689 f(x) = 500(0.04)x, $512 f(x) = 500(1.04)x, $608 f(x) = 500(1.04)x, $527

    P is the initial amount, 500. r is the interest rate in decimal, 0.04, so the foumula is \[P=500(1+0.04)^x\] \[P=500(1.04)^x\] Plug in 5 for x to get the amount after 5 years
