Answer:
The answer to your question is below
Step-by-step explanation:
First way
20 = 5(-3 + x) expand
20 = -15 + 5x simplify like terms
5x = 20 + 15
5x = 35 divide both sides by 5
5x/5 = 35/5
x = 7
Second way
20/5 = 5/5 (-3 + x) Divide both sides by 5
4 = -3 + x Add +3 in both sides
4 + 3 = -3 + 3 + x Simplify like terms
7 = x
I think it’s A or D not sure. Hope I helped.

===============================================
Explanation:
The two endpoints are (-3,1) and (-1,-4)
Apply the distance formula
So the approximate distance is roughly 5.38 units and the exact distance is units.
--------------
As a slight alternative, you can plot the point (-3,-4) and draw a right triangle. Then apply the pythagorean theorem to find the length of the hypotenuse. The vertical and horizontal legs are 5 and 2 units respectively.
It turns out that the distance formula is essentially a modified form of the pythagorean theorem.
It is given in the question that the formula of volume of cone is
Where V is the volume, r is the radius and h is the height.
And we have to find an expression for h.
First we multiply both sides by 3, and on doing that we will get
Now to isolate h, we have to get rid of pi r square by dividing.
Therefore the correct option is B.
