Answer:
-2
Step-by-step explanation:
The axis of symmetry divides the quadratic exactly in half. If one x-intercept is 8, then the other will be the same distance on the other side of it. 8 is 5 from 3 where the axis of symmetry is. So 3-5 = -2. -2 will be the other intercept.
A. 15.7 ft
circumference = 2πr
radius= half the diameter 5/2=2.5
2(3.14)(2.5)=15.7 ft
V= 14.13
Information needed:
V= 4/3r^3
= 3.14
r= 3/2
Solve:
V= 4/3(3.14)(3/2)^3
V= 4/3(3.14)(27/8)
16
(10-6)^2
4^2=16
