Answer:

r = $\frac{A + 32}{\pi }$

Step-by-step explanation:

A = πr-32

using algebraic manipulation to isolate r

A + 32 = πr-32 + 32

A + 32 = πr

(A+32)/π = πr/π

r = $\frac{A + 32}{\pi }$

Solve x^2+4x+8. What is the vertex?

LenKa [72]

Answer:

$(-2,4)$

Step-by-step explanation:

Well to start with there is a vertex formula which is $-\frac{b}{2a} =h\\$ , $f(h)$

Your initial equation is $x^2+4x+8$ where $ax^2+bx+c$ . So you would plug in your numbers $-\frac{4}{2(1)}$ $=-\frac{4}{2} =-2$ we know know that $h=-2$ so plug in h in $f(-2)$ which would be (-2)^2+4(-2)+8 = 4-8+8 = 4 which would make the vertex $(-2,4)$
