RUDIKE [14]3 years ago

The data is larger for intermediate values of x, so the parabola opens downward. That leaves only the 2nd and 4th choices, where the x² coefficient is negative.

To determine which of those is appropriate, it is only necessary to consider x=1. The 2nd choice will give a y-value near 100; the 4th choice will give a y-value near 250.

The fourth choice is appropriate:

... y = -9.16x² +73.04x +183.3

_____

Alternatively, you can consider that for the x-coordinate of the vertex to be positive (it's about +4), the coefficients of the x² and x terms must have opposite signs. Using this consideration, you don't even need to evaluate the expression to determine that the 4th choice is the correct one.

Volume of a hemisphere formula?
Allisa [31]
To find the volume of a sphere you use...

V = 4/3 pi r^3

"Hemi-" means half. So we would divide by 2.

V= (4/3 pi r^3) / 2
