The long jump record, in feet, at a particular school can be modeled by f(x) = 20.4 + 2.1ln(x + 1) where x is the number of years since records began to be kept at the school. What is the record for the long jump 8 years after record started being kept? Round your answer to the nearest tenth and do not enter the units.

An arrow is shot into the air with an upward velocity of 48 feet per second from a hill 32 feet high. The function that gives the height of the arrow at any time t is h(t) = 32 + 48t - 16t^2. Find the times at which the arrow will be 64 feet above the ground. Include pictures, drawings, and graphs to support your solution.
