The correct option is B - Where the given data is plot correctly.
Answer:
Step-by-step explanation:
Hint: 1- 2sin²x = Cos 2x
LHS = 1 - 2Sin² (π/4 - Ф/2)
= Cos 2 *(π/4 - Ф/2)
= Cos 2*π/4 - 2*Ф/2
= Cos π/2 - Ф
= Sin Ф = RHS
Answer: 2.727 miles per hour
Step By Step:
4 ft/sec X 3600 sec/hour = 14400 ft/hour
14400 ft/hour / 5280 ft/mile = 2.727 miles/hour
