114.5 because if he’s 13 he should weigh about 100-110 pounds so it’s 114.5
You will get $2.03 back in change
To find the volume of the whole, you will use the formula for finding the volume of a cone. V = 1/3 x r^2 x h.
You will first need to find the radius by using the information given about the circumference and the circumference formula.
C = pi x d
44 = 22/7 d
d = 14 feet.
Then use the diameter to find the radius of 7 feet.
V = 1/3 x r^2 x h
1/3 x 7^2 x 3
V = 49 cubic feet
To determine the maximum value of a quadratic function opening downwards, we are going to find the vertex; then the y-value of the vertex will be our maximum.
To find the vertex (h,k) (where h=x-coordinate and k=y-coordinate) of a quadratic function of the form

we'll use the vertex formula:

, and then we are going to replace that value in our original function to find k.
So, in our function

,

and

.
Lets replace those values in our vertex formula:



Now that we know the x-coordinate of our vertex, lets replace it in the original function, to get the y-coordinate:



We just prove that the vertex of

is (2,1), and for the graph we can tell that the vertex of

is (-2,4). The only thing left is compare their y-coordinates to determine w<span>hich one has the greater maximum value. Since 4>1, we can conclude that </span>

has the greater maximum.
