Aferris wheel is 35 meters in diameter and boarded at ground level. the wheel makes one full rotation every 8 minutes, and at time t = 0 you are at the 9 o'clock position and descending. let f(t) denote your height (in meters) above ground at t minutes. find a formula for f(t).

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
