Question 1: tan x = 3/4 and 0 Question 2: sin x 7/25, and 0 < x < pi/2, what is cos ( x - 3pi/2 )

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
