31.4 cm
Step-by-step explanation:
the radius is 5 so the diameter is 10 so you'll have to multiply 3.14 by 10 not 5
5x+(-4)-5x=6x+4-5x
-4=x+4
x=-8
To get rid of 5x on the left side.

all of order. I'll have to confirm this though
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
Step-by-step explanation:

But we know that

and

so this leaves us with just
