The correct answer is A.
Answer:
The wax will fill the mold a bit more than halfway.
Step-by-step explanation:
The volume of a sphere with radius is:
.
The radius of this sphere of wax is ; Its volume would be:
.
Assume that the wax here does not evaporate, combust, or otherwise disappear. .
The volume of a rectangular prism is equal to .
For this mold with a rectangular prism shape:
.
Half of that would be:
.
Compare these two volumes to the volume of wax available:
.
In other words, the wax will fill the mold a bit more than halfway, but not completely.
The quadratic equation y = -x^2 - 4x - 3 has a degree of 2
The vertex of the function is (-2,1)
<h3>How to graph the function?</h3>
The equation of the function is:
y = -x^2 - 4x - 3
Differentiate
y' = -2x - 4
Set to 0
-2x - 4 = 0
Solve for x
x = -2
Substitute -2 for x in y = -x^2 - 4x - 3
y = -(2)^2 - 4(-2) - 3
y = 1
The above means that the vertex of the function is (-2,1)
See attachment for the graph of the function

The answer would be y = 6x.
The reason for this is that when we add a number in front of x, it makes it go up vertically by the factor of that number. So if we are to stretch the graph vertically, the only way we can do it is by making 6 the coefficient.
