Three hundred ninety one thousand thirty two
Answer: 15c
Step-by-step explanation:
When you come across any question that mentions [the product of a and b] means a × b
- the product of 6 and 7 is 42, 6 × 7=42
- the product of x and y is xy, x × y=xy
<u>Solve:</u>
The product of 15 and c
<h2>15 × c=15c</h2>
The vertex of a quadratic occurs when the velocity, dy/dx=0.
dy/dx=2x+8, so dy/dx=0 only when:
2x+8=0
2x=-8
x=-4, now you find the y coordinate which is:
y(-4)=(-4)^2+8(-4)+12
y(-4)=16-32+12
y(-4)=-4 so the vertex is at the point:
(-4,-4)
