Orca J-43 is sighted in Pudget Sound at the following depths (in feet) at certain times t (in minutes) measured from sea level. D(t) =    59 0 ≤ t < 5 t 2 − 22t + 144 5 ≤ t < 10 24 10 ≤ t < 18 8(t − 15) 18 ≤ t ≤ 22 (a) What is the range of the function D? Strategy then final result, no algebra steps (b) Another orca, K-97, also shows her presence in Pudget sound. If her depths (measured at the same time as above) is given by g(t) = 2t + 1, at which times are both whales at the same depth? Strategy then final result, no algebra steps

Certain species of blind fish living in perpetual darkness in the ocean depths have evolved from ancestors that could see. Research indicates that the brain centers for vision in these fish is degenerating, whereas the brain centers controlling other senses are enlarging. What might be the MOST probable reason for the loss of vision in these fish? A. exposure to mutagens that caused the loss of vision B. progressive selection of genetic variants in the population leading to blindness as...

A 100 foot long horizontal pipeline transporting benzene develops a leak 43 feet from the high-pressure end. The diameter of the leak is estimated to be 0.1 inch. At the time, the upstream pressure in the pipeline is 50 psig and the downstream pressure is 40 psig. Estimate the mass flow rate of benzene through the leak. The specific gravity of benzene is 0.8794.
