Use the formula @ = to find the value of the missing variable. @ = 0.9509 radians per sec, t= 11.63 sec The missing variable is 0 = radians. (Type an integer or decimal rounded to the nearest hundredth as needed.)

Use a right triangle to simplify the given expression as shown. Assume x 7 0.

Jeremy boards a Ferris wheel at the 3- o'clock position and rides the Ferris wheel for multiple revolutions. The Ferris wheel rotates at a constant angular speed of 7.3 radians per minute and has a radius of 50 feet. Let t represent the number of seconds since the Ferris wheel started rotating. a. Write an expression (in terms of t) to represent the varying number of radians Jeremy has swept out since the Ferris wheel started rotating. Preview b. Write a function f that determines Jeremy's distance above the center of the Ferris wheel (in feet) in terms of t. f(t) = Preview c. How long does it take for Jeremy to complete one full revolution on the Ferris wheel? Preview minutes
