- Repeat the previous exercise to find the formula forthe APY of an account that compounds daily. Usethe results from this and the previous exercise todevelop a function I(n)for the APY of any accountthat compounds n times per year.arrow_forwardThe formula for the amount A in an investmentaccount with a nominal interest rate r at any timet is given by A(t)=a(e)rt, where a is the amount ofprincipal initially deposited into an account thatcompounds continuously. Prove that the percentageof interest earned to principal at any time t can becalculated with the formula I(t)=ert1.arrow_forwardWhen a certain drug is taken orally, the concentration of the drug in the patient's bloodstream After t minutes is given by C(t)=0.06t0.0002t2 where 0t240 and concentration is measured in mg/L .When is the maximum serum concentration reached, and what is that maximum concentration?arrow_forward
- The rate of change of an autocatalytic chemical reaction is kQxkx2 where Q is the amount of the original substance, x is the amount of substance formed, and k is a constant of proportionality. Factor the expression.arrow_forwardThe population P (in millions) of Texas from 2001 through 2014 can be approximated by the model P=20.913e0.0184t, where t represents the year, with t=1 corresponding to 2001. According to this model, when will the population reach 32 million?arrow_forwardx2 +1 Find a formula for the tangent line for y = at x = 1. x + 1 e rational function does not simplify.arrow_forward
- When fertilizer is introduced to a lake, it may or may not affect the kilograms of algae that are in the lake. In each of the cases below, write a formula for, A(t), the kilograms of algae in the lake t days after the fertilizer is introduced, Assume there are 90 kilograms of algae in the lake when t = 0. (a) the kilograms of algae remain constant each day. A(t)- (b) the kilograms of algae decrease at a continuous rate of 4%i each day A(t)- (C) the kilodrams of algae increase by a factor of 1.14 each day Alt)-arrow_forwarde* 3. For the function f(x) = find f'(x) two different ways – one using the product rule and the other 4x* using the quotient rule. Fully simplify including reducing fractions to lowest terms.arrow_forward18 Select the correct answer. A population's instantaneous growth rate is the rate at which it grows for every instant in time. Function r gives the instantaneous growth rate of a bacterial culture x hours after the start of an experiment. r(x) = 0.01(x + 2)(x2 - 9) How many hours after the experiment began was the instantaneous growth rate equal to 0?
