Answer: -91
Step-by-step explanation:
(2-5)^2-(4*5^2)
Follow the order of operations.
2-5=-3 Which uses the property of parentheses
(-3)^2-(4*5^2)
(-3)^2=9 which uses the property of exponents
5^2=25 which uses the property of exponents
9-(4*25)
4*25=100 which uses the property of multiplication
=9-100 which uses the property of subtraction
=-91
Answer:
Plot and connect (5,4), (3,0) and (7,0).
Step-by-step explanation:
This is in factored form and can be graphed directly from the equation. The equation shows the x-intercepts.
The x-intercepts are found by solving for x using the zero product rule.
(x-3)=0 so x = 3
(x-7) = 0 so x = 7
The intercepts are (3,0) and (7,0). Plot the points. The vertex will occur halfway between these points. 7-3 / 2 = 4/2 = 2. This means the axis of symmetry is at x = 5 and this is the x-coordinate of the vertex too.
Substitute x = 5 into the equation and solve for y.
-(5-3)(5-7) = -(2)(-2) = 4
The vertex is (5,4). Plot it and connect the points.

or
4000π
Step-by-step explanation:
the equation is 50π×80
this is because you have to find the area of the circle which is diameter times pi and then you multiply that by the height of the cylinder
