I need help with these questions

1.

If a rock is dropped from a height of 116 ft, its poistion t seconds after it is dropped until it hits the ground is given by the function 5(t) = 16%2 + 116. Round values below to 3 decimal places. How long does it take the rock to hit the ground? Find the average velocity of the rock from when it is released until when it hits the ground. What time after the rock is thrown will its instantaneous velocity be equal to its average velcity? (Apply the Mean Value Theorem) :] seconds after it is thrown 2 Find all local extreme values of an) = 53:3 + 8w2 303: 100. The FIRST local extreme value, moving from left to right on the graph, is a at :i- The SECOND extreme value, moving from left to right on the graph, is a at :i- For the above rational function f( x ) = C]
