In triangle abc, m_a = 45°, mzb = 40°, and a = 7. which equation should you
solve to find b?
a. c0545º = cos40
b. sin45º = sin40
c. 62 = 72 - 2(7) bcos40°
d. sin45º = singo

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.
