Lauren ‘tutored’(i think that’s what the question said idk) 4 students. take the 3/4 and multiply it by the value of time(6 hours). the calculated answer is 4.5, but you can’t half-tutor a student, and you can’t round up, so the answer is 4
Since
h(x) = g(f(x)), h'(x) = g'(f(x))×f'(x) (Chain rule).
Setting x=3 we get
h'(3) = g'(f(3))×f'(3)
Plugging in values we get
h'(3) = g'(4)×7
h'(3) = 2×7
h'(3) = 14
You need more information, which one is the adjacent and opposite (it’s either 5/12 or 12/5)
