Answer:
Step-by-step explanation:
In the figure attached,
Vertices of the triangle ABC are A(-4, 4), B(-1, 4) and (-1, 2)
When we reflect this figure across a line y = 1
Vertices of the image triangle A'B'C' will be
Coordinates of A'
A(-4, 4) → A'[(1 + 5), 4]
→ A'(6, 4)
Coordinates of B'
B(-1, 4) → B'(-1 + 4, 4)
→ B'(3, 4)
Coordinates of C',
C(-1, 2) → C'[(-1 + 4), 2]
→ C'(3, 2)
Graph these points and join them to form the image triangle A'B'C'.
Sounds like 10.0 ft refers to the height/diameter of the wheel, in which case its radius is 5.0 ft.
In one complete revolution, a point on the edge of the wheel travels 2π*(5.0 ft) = 10π ft, so the point's linear speed (and thus the current's speed) is
(5.0 rev/min) * (10π ft/rev) = 50π ft/min
Convert this to mi/h using
1 mi = 5280 ft
1 h = 60 min
==> (50π ft/min) * (1/5280 mi/ft) * (60 min/hr) = 1.8 mi/h
