Answer:

F(1,5)

Step-by-step explanation:

This is a vertical parabola.

The vertex is at (1,4).

The directrix is y=3.

The distance from the vertex to the directrix is p=1

The focus is (1,4+p), which is (1,4+1)

Therefore the focus is (1,5)

bogdanovich [222]

Answer:

11 pounds of deluxe, 35 pounds of regular

Step-by-step explanation:

d ≥ 11

d + r ≥ 46

C = 7d + 5r

d = 11

r = 35

C = 252
