General formula of the parabola in vertex form is
f(x) =(x-h)² +k, where (h,k) is a vertex of the parabola.
f(x) = (x + 5)²- 28
h= -5, k = -28,
so (-5, -28) is a vertex of the given parabola.
Answer is A.
Part 1:
180 = 5p+98 + 9p-2
180 = 14p + 96
84 = 14p
6 = p
part 2:
angle S will be the same as angle Q, so:
9p-2
9(6)-2
54-2
M
