a linier functin of h models a relationship in which the dependent varible increses 1 unit every 5 units the independent varible decreses the value of the function at 0 is 3

The answer is 41.7 because 1.39 times 30 is 41.7

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.
