Unformatted text preview: Sketch the graphs of each of the following functions by hand. Use a graphing calculator to check your answer. 11. 13. 15. 16. 17. 108 y = —2sin(x + 7:) 12. f(x) = %sin(3x) f(x)=cos(4(x—%)) 14. y=3cos(x+%)+3 f(x)= 7sin(]:x)— 3 A wooden water wheel makes ten revolutions every minute. At its lowest point it dips down 2 feet below the surface of the water and at its highest point it is 18 feet above the water. A snail attaches to the edge of the wheel when the wheel is at its lowest point and rides the wheel as it goes around. Use this information to write an equation that gives the height of the snail over time. To keep baby Cristina entertained, her mother often puts her in a Baby Jump Up. It is a seat on the end of a strong spring that attaches in a doorway. When her mom puts Cristina in, she notices that the seat drops to just 8 inches above the floor. Cristina starts to jump and 1.5 seconds later, the seat reaches its highest point of 20 inches above the ground. The seat continues to bounce up and down as time passes. Use this information to write the an equation that gives the height of Cristina’s Baby Jump Up seat over time. (Note: You can start the graph at the point where the seat is at its lowest point.) © 2015 CPM Educational Program. All rights reserved. Core Connections Integrated III ...

    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.
