II. Ferris Wheel The height of a chair on a Ferris wheel follows the equation y =5.7sin(0.31x)+ 7.9 , where y is the height (in meters) and x is the time (in seconds). Where necessary round all answers to 2 decimal places
a) What is the maximum height the Ferris wheel reaches?
b) What is the minimum height the Ferris wheel reaches?
c) How long does it take the Ferris wheel to make 1 complete cycle?
d) How high is the Ferris wheel after 12.5 seconds?
e) In the during the first rotation of the Ferris wheel, at what time(s) does the it reach 10 m?

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.

Which diagram shows lines that must be parallel lines cut by transversal?

(01.03 mc) which of the following is a step in simplifying the expression x multiplied by y to the power of 2 over x to the power of negative 3 multiplied by y to the power of 3, the whole to the power of negative 4. select one: a. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 7 multiplied by y to the power of negative 1. b. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of 12 multiplied by y to the power of negative 12. c. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of negative 3 multiplied by y to the power of 3. d. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 3 multiplied by y to the power of 3.
