What is the product of 11 ft x 285 ft

Sam claims that cos x =sin y if x and y are congruent angels. is sam correct ?

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9
