<em>Good</em><em> </em><em>luck</em><em> </em><em>on</em><em> </em><em>your</em><em> </em><em>assignment</em>
Answer:
the vertex represents a maximum
Vertex is (4,7)
f(x)=-(x-4)^2+7
Step-by-step explanation:
Given the function ![f(x)=-x^2+8x+9](https://tex.z-dn.net/?f=f%28x%29%3D-x%5E2%2B8x%2B9)
Equation is in the form of y=ax^2+bx+c
![a=-1](https://tex.z-dn.net/?f=a%3D-1)
When 'a' is negative, then vertex is maximum
when 'a' is positive, then vertex is minimum
is negative, so the vertex represents a maximum
, factor out negative
Take out negative sign in common
Hello There!
Surface area of a sphere formula:
4πr²
SA = 4π14.21²
SA = 2537.5mm³
Surface area of a cone formula:
1/3πr²5
SA = 1/3π3²15.1
SA = 142.3in³
Pyramid:
SA = 124.3
Hope This Helps You!
Good Luck :)
