- The 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_forwardFind the quadratic approximation to f(x) = /x + 3 near a = 1. Graph f, the quadratic approximation, and the linear approximation from Example 1 on a common screen. What do you conclude?arrow_forwardWhich of the following is a true statement? d (10) = 5 (104) da O The equation of the tangent line to the parabola y = x2 at (-2, 4) is y – 4 = 2x (x + 2). O The slope of the tangent line to y = 4x + 1 is never 0. O The nth derivative da" d" (5x3 + 2x + 5) equals O for every integern> 3. O If f is continuous at x = a, then f is differentiable at x = a.arrow_forward
