Please help with both. Please show all work in a clear format so that I may have a better understanding.

Use the information to find and compare Ay and dy. (Round your answers to four decimal places.) V = x* +3 x = -5 Ax = dx = 0.01 Ay = dyThe period of a pendulum is given by the equation shown below, where .L is the length of the pendulum in feet, g is the acceleration due to gravity, and Tis the time in seconds. T=211 i lulg The pendulum has been subjected to an increase in temperature such that the length has increased by 2% (a) Find the approximate percent change in the period. % (b) Using the result in part (a), nd the approximate error in this pendulum clock in 1 day. min
