f and g are both continuous for all real numbers, and g is strictly increasing. The function h is given by h(x)=g(f(x)). Explain why there must be a value r for 1<r<3 such that h(r)=8.
since f and g are both continuous, that means h is also continuous. And since h(1)<8<h(3), there exists a value "r" such that h(r)=8 on [1,3]
A rectangle has a width of 16 inches, and a length of 18 inches, What is the optimum volume of the box?
361.097 inches3
After an exam, students begin posting memes at a rate of m(t)=231sin(pi(t)/24) for 0<t<24, where m is measured in students per hour and t in hours after the exam ends. after 12 hours, the teacher begins cancelling the grades of those who have made memes at a rate of C(t)=3e0.26439t^2/24 for c is is measured in students per hour and t is in hours. Let S(t) equal those who have posted memes, but have not yet had their scored canceled. At t=19, is S(t) getting larger or smaller, and explain?
S(19) is getting smaller because S'(19)=-19.4296, which is less than 0.
