In tennis a lob can be used to buy time to get into position. The approximate height s (feet) for a tennis ball that is hit at upward at voft/sec from a height of soft is modeled by s = 16t² + vot + So If the ball is hit at 55 feet per second from a height of 5.2 feet, approximately how long will the tennis ball be in the air before it strikes the ground?

Q9: please answer all the parts to this question with each answer clearly indicating which answer is for which part and please make sure to round to the right decimal places. Prednisone is a corticosteroid used to treat many inflammatory diseases such as asthma, ulcerative colitis, arthritis, or acne. However, prolonged use of the drug can cause patients to develop osteoporosis, low bone density. Recently a new drug, prednisolone has been developed that acts as anti-inflammatory with fewer side effects. To compare the drugs impact on bone density a study was done in which two groups of cats received equivalent doses of prednisone or prednisolone for an equivalent time period. At the end of the treatment period the bone density of both groups was measured. Each measurement represents an individual cat that was given either prednisone or prednisolone. Now the researchers want to use a t-test to see if the data show any differences between the treatments. Ho: There is no difference in…
