Answer:
<em>Her rate of change is 75 ft/h</em>
Step-by-step explanation:
<u>Rate of Change</u>
It measures how one quantity varies with respect to another. The second variable usually is the time.
The climber is hiking. We are given two points of her progress: At 2 hours, she is at 400 ft. This corresponds to the point (2,400).
At 6 hours, she is at 700 ft. This is the point (6,700)
The rate of change is the slope between these two points or the quotient of the variations of each variable:



Her rate of change is 75 ft/h
Answer:
x = pi/2..only
Step-by-step explanation:
The equation states that...,
tan^2x.sin x = tan^2x
;we simplify the equation by dividing both sides by tan^2x...which then leaves our equation as,
; sin x = 1
; x = sin^-1 (1)
; Hence x = pi/2
