From the observation deck of a skyscraper, Jamal measures a 51 angle of depression to a ship in the harbor below. If the observation deck is 1123 feet high, what is the horizontal distance from the base of the skyscraper out to the ship? Round your answer to the nearest hundredth of a foot if necessary.

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
