A mathematician stands on a beach with his dog at point A. He throws a tennis ball so that it hits the water at point B. The o as quickly as possible, runs along the straight beach line to point D and then swims from point D to point B to retrieve his b edge of the beach closest to the tennis ball (see figure).

Question
A mathematician stands on a beach with his dog at point A. He throws a tennis ball so that it hits the water at point B. The dog, wanting to get to the tennis ball
as quickly as possible, runs along the straight beach line to point D and then swims from point D to point B to retrieve his ball. ASsume C is the point on the
edge of the beach closest to the tennis ball (see figure). Complete parts (a) through (d) below.
B
D.
C.
a. Assume the dog runs at speed r and swims at speed s, where r>s and both are measured in meters/second. Also assume the lengths of BC, CD, and AC are x, y, and z, respectively. Find
a function T(y) representing the total time it takes for the dog to get to the ball.
T(y) =
