Answer:
Step-by-step explanation:
The surface area of the cone shaped roof is:
The cost of roofing per square feet is: (USD stands for US dollar)
The domain is the value of x, the range is the value of y.
A parabola opens infinitely to the right and left, so x can be any number, the domain is all real numbers
Vertically, however, a parabola opens only one way, either upward or downward. when it opens upward from a a certain level, say, the lower point (the vertex) has a y coordinate of 2, we say the range is all real numbers larger than or equal to 2, or y≥2. When it opens downward, we say the range is all real numbers smaller or equal to 2, y≤2
Your answer will be:
The total number of marbles that are not black.
It could be:
2/4
4/8
8/16
3/6
5/10
