Exercise #3: A farmer has 30 feet of fencing that he is using for the rectangular pen shown below that also requires fencing for a dividing pen. The variables xandy are related by the equation. 3x+2y=30 (a) solve this equation for y in terms of x

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

With out knowing the functions you have to chose form, this could be one.y = 5.00xx = hours worked and y = the money he will earn.
