D 59. Simple use of order of operations were needed.
We know that
<span>When two chords intersect each other inside a circle, the products of their segments are equal
</span>
so
CP*PD=AP*PB
x*y=2*PB-----------> 28=2*PB----------> PB=14
the answer is
PB=14
H = -16t² + 64t + 80 (:16)
H = -t² + 4t + 5
/\ = b²-4ac
/\ = 4²-4.(-1).5
/\ = 16+20
/\ = 36
Yv = -/\ / 4a
Yv = -36/4.(-1)
Yv = -36/-4
Yv = 9
