Sphere volume = PI * diameter^3 / / 6=
PI * 9^3 /6 =
PI * 729 / 6 =
381.70
So, answer is A
Answer:
pus$y
Step-by-step explanation:
You need to find the vertex of the function.
The easiest way to do this is to graph it on a calculator like desmos.
but you can find the line of symmetry with this equation. x=-b/2a
x=-112/2(-16)
x= 3.5
Then plug that into the equation.
-16(3.5)^2+112(3.5)+30
226
226ft is the maximum height.
You have 2 points with the same x value of 2 and 2 points with the same y value of 4.
You now need 2 points with the same x value of 4 ( you are given 1) and 2 y values of 1 ( you are given 1.
The missing point would need to be (4,1)
The width would be x2-x1 = 4-2 = 2 units
The length would be y2-y1 = 4-1 = 3 units
Area = 3x 2 = 6 square units
Multiply -2 and x, and you’ll have -2x. Then multiply -2 and 5, and you’ll have -10. Therefore, -2x-10=4, but we’re not done yet. We need to get x by itself, so what we’re gonna have to do is add 10 to both sides. Now you’ll have -2x=14, and when you divide both sides by -2, you’ll have x=-7 which will be your answer
