The zeros are the x-intercepts, which are -2 and 4.
The axis of symmetry is x = 1
The vertex of the graph is (1,9)
Answer:
area = 19.2325
perimeter = 19.495
Step-by-step explanation:
circular cake diameter = 14 in
radius = d / 2 = 14/2 = 7 in
cut into 8 equal slices
so area of 1 slice = Total area / 8
A = pi * r^2
= 3.14 * 7 * 7
= 3.14 * 49
= 153.86
so area of one slice = 153.86/8 = 19.2325
so for perimeter also it is 1/8 of the total cake perimeter and two times the radius
cake perimeter = P = 2*pi*r
= 2 * 3.14 * 7
= 43.96
so perimeter of slice = 2*r + 1/8 * 43.96
= 2*7 + 1/8 * 43.96
= 19.495
