45
15 is a multiple of 3
30 is a multiple of 3
45 is NOT a multiple of 3
60 is a multiple of 3
Ect.
Answer: 60 decrease or 150 decrease
Step-by-step explanation:
<u>Part A</u>
<u />
So, the x-intercepts are 
<u>Part B</u>
The vertex will be a minimum because the coefficient of
is positive.
The x-coordinate of the vertex is 
Substituting this back into the function, we get 
So, the coordinates of the vertex are 
<u>Part C</u>
Plot the vertex and the x-intercepts and draw a parabola that passes through these three points.
The graph is shown in the attached image.
A whole number is a fraction with a denominator of one
16 pi? well... 16 pi = 50.2654824574. So... the diameter would be 16 and the radius would be 8. I think!
