Please Help its my birthday !!! Part A: Without using a graphing calculator, which equation could be represented by the accompanying graph?

Question 10 options:

y=2x

y=2−x

y=x2−2

y=−2x

Part B: Explain how you selected the equation in Part A

Question 11 options:

none

Step-by-step explanation:

Because they are all straight angle line

Y=2x —> positive line

Y=2-x —> negative line

Y=x2-2 —> positive line

Y=-2x —> negative line

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
