The focus is above the directrix, so the parabola opens upward—its vertical scale factor is positive (+1/12). The line of symmetry is x=-5, so the vertex form of the equation will have the factor (x -(-5))² = (x+5)². The choice that meets both these requirements is
D. f(x) = (1/12)(x + 5)² + 2
Answer:
1 1/8
Step-by-step explanation:
3/8 * 3
3/8 * 3/1
9/8
change to a mixed number
8 goes into 9 one time with 1 left over
1 1/8
In order going down:
5 3/5
6 5/6
4 2/3
10 1/3
11 2/3
The answer is D 75% of the original volume is left.
