52. Find a formula for d dx f (3 x 2 ) assuming f is differentiable. 53. What is the 45th derivative of y = sin( x )? 54. Find a formula for f ( n ) ( x ) if f ( x ) = xe x . Recall that f ( n ) denotes the n th derivative of f . 55. Find a formula for g ( n ) ( x ) if g ( x ) = 1 x . Recall that g ( n ) denotes the n th derivative of g . 56. Find an equation of the tangent to the graph of y = f 0 ( x ) at x = 1 where f ( x ) = x 5 - 3 x 2 + x . 57. For each of the graphs below, provide a rough sketch of the derivative of the corresponding function. Related Rates 58. Suppose x and y are differentiable functions of t and are related by y = x 2 - 1. Find dy/dt when x = 2 given that dx/dt = 3. 59. A rock is dropped into a calm pond, causing ripples in the shape of concentric circles. The radius of the outer ripple is increasing at a rate of 12 cm/s. When the radius is 30 cm, at what rate is the total area of the outer ripple changing? 60. A spherical balloon is deflated so that its volume decreases at a constant rate of 3 in 3 / s. How fast is the balloon’s diameter decreasing when the radius is 2 inches? 61. A 10-foot ladder is leaning against a building. If the top of the ladder slides down the wall at a constant rate of 2 feet per second, how fast is the acute angle that the ladder makes with the ground decreasing when the top of the ladder is 5 feet from the ground? (Give your answer in radians per second.)

At what rate is the distance between the cars increasing two hours later?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
