Answer:
D
Step-by-step explanation:
The answer is D because a circle has at least a 360 degree and a 180 is a half circle.
Answer:
A
Step-by-step explanation:
The answer is 586.17 cm^2
It has a minimum value at x = 3 and f(x) = 4
Vertex form is
f(x) = a(x - 3)^2 + 4 where a is some constant to be found
From the graph when x = 5 f(x) = 15, so
15 = a * 2^2 + 4
a = 15-4/4 = 11/4
so our equation is f(x) = 11/4(x - 3)^2 + 4
