What is 100-34= helll

Measures of the angle of r, 31 s (x+4) t (3x+9)

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.

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle
