Let f(z) = 8x + 15 - 1let. Then the equation of the tangent line to the graph of f(z) at the point (0, 4) is given by y = me + b for n Given f(z) = 4e3z -3 df dz Use the chain rule to find the derivative of y = 3e -525 +10r10 Find a -(37). Type In(x) for the natural logartihtm function. Differentiate f(t) = 7-5t +6 f' (t) = Find the derivative of f (z) = 2625.51 f' (2) = Use implicit differentiation to find - without first solving for y. x'ty = ey dy Question Help: Virden MM- An isotope of the element erbium has a half-life of approximately 13 hours. Initially there are 10 grams of the isotope present. a. Write the exponential function that relates the amount of substance remaining, A(t) measured in grams, as a function of t, measured in hours. A(t) = grams b. Use part a. to determine the rate at which the substance is decaying after t hours. A' (t) = grams per hour c. Use part b. to determine the rate of decay at 4 hours. Round to four decimal places. A' (4) = grams per hour Let f(x) = 5In(7z) f' (x) = f' (2) = Question Wala
