Answer:
y = -3x²
Is a concave down with a maximum turning point at (0,0)
y = ⅓(x²)
Is a concave up with a minimum turning point at (0,0)
(y+1)=-8/10 (x-6)
5y+5=-4x+24
5y=-4x+19
Answer: V=9651 ft^3
Explanation: This is a volume question and the formula for volume of a cylinder is πr^2h.
The radius is the diameter divided by 2, which is 8.
We can put the equation in terms of π by doing π*(8^2*48)=3072π.
Solving this gives us about 9650.972632, which you can round to get 9651.
Hey there!

Good luck on your assignment and enjoy your day!
