g(f(2))=g(4)=−3. g(f(2))=g(4)=−3. Question 14 1.67 / 1.67 pts Suppose a quantity Q can be modeled by a cosine function. The maximum value over one period is 40 and the minimum value is -10. Calculate the amplitude of the function. 20 Correct! 25 50 40 30 The amplitude is half the distance between the minimum and maximum values. For this problem that distance is 50, so the amplitude is 25. Question 15 1.66 / 1.66 pts Solve for t t using natural logarithms. 36=12(1.25) t 36=12(1.25)t

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
