Answer:
5
Step-by-step explanation:
34.05
34.05 x 10 to the power of six = 3405000
decimal point needs to move 5 places to go after the last zero
11.25
The equation for a parabola is:
y − k = 1/(4p) (x − h)²
where (h, k) is the vertex and p is the distance from the focus to the vertex.
1/(4p) = 1/45
4p = 45
p = 11.25
The distance from the vertex to the focus is 11.25 inches.
1. k = 15
2. d = 20
3. n = 3
