8. The Millennium Ferris wheel in London has a radius of 66 meters. The wheel moves rather slowly
it takes 30 minutes to travel around the wheel. At the highest point the riders are 135 meters off of
the ground. Write an equation involving sinusoidal function to model the elevation of a rider above
the ground as a function of the number of minutes since getting on the Ferris wheel at the lowest
point. Draw a diagram to assist you with the problem. Clearly show your work

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
