Answer:
r = 6 mph and f = 11 mph
Step-by-step explanation:
Representations:
1) speed of faster cyclist: f = r + 5
2) speed of slower cyclist: r
Distances covered:
(r + 5)(5 hr) + r(5) = 55 mi (total distance covered)
Then 5r + 25 + 5r = 55, or, after reducing this equation:
r + 5 + r = 11, or
2r = 6
Then r = 6 mph and f = 11 mph

Answer:
-3.5
Step-by-step explanation:
It is halfway between -3 and -4
- R = -3 + (-4) / 2
- R = -7/2
- R = -3.5
A standard form of the equation of a rotated parabola is
(y - k)² = 4p(x - h)
where
(h, k) is the location of the vertex.
(h+p, k) is the location of the focus.
The directrix is the line x = h - p
Because the focus is at (-1, 4), therefore
h + p = -1 (1)
k = 4 (2)
Because the directrix is x = 5, therefore
h - p = 5 (3)
Add equations(1) and (3) to obtain
h + p + (h - p) = -1 + 5
2h = 4
h = 2
From (1), obtain
p = -1 - h = -1 - 2 = -3
The equation of the parabola is
(y - 4)² = -12(x - 2)
Answer: (y - 4)² = -12(x - 2)
