Hue's boat used 5 gallons of gasoline in 4 hours. at this rate, how many gallons of gasoline will the boat use in 10 hours?

Gallons used = hours

5 = 4
x = 10
Now cross multiply

5*10=4*x
50=4x
50/4=x

x= 12.5 gallons

Ask google i believe they can you with that question

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.
