John and Phil were playing tennis. They each hit a tennis ball at the same time and measured the how high the tennis balls went and how long it took for each one to
land on the tennis court. The graph represents the height of the tennis ball 1
seconds after it was hit by john

The function f given by $ (1) = (-161 – 2) (1 – Zepresents the height of the
tennis ball t seconds after it was hit by Phil. In both functions, height is measured in feet.
Part 1. Whose tennis ball hit the tennis court first? When did that happen?
Part 2. Phil's tennis ball reached its maximum height after a seconds. Did Phil's
tennis ball reach a higher maximum than John's tennis ball?
Part 3. What was the maximum height of Phil's tennis ball? Round your answer to
the nearest whole number.

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.

83-45=38

38 was the other number

hope your goes well, here's a turkey

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
