Answer:
The answer would be 30.
Step-by-step explanation:
180/6 = 30.
a) is correct
b) y = -a(x - 2.5)² + h
(5.5,0)
0 = -a(5.5-2.5)² + h
h = 9a
a = h/9
48 = -a(0-2.5)² + h
h = 48 + 6.25a
h = 48 + 6.25(h/9)
h = 157.0909090681
Range: [0,157]
c) (80-144)/(4.5-3)
= -42⅔ or -42.67
x=771
−771 + x = 0
x − 771 = 0
x − 771 + 771 = 0 + 771
Answer: At least 13
