Is 5 gallons greater than, less than, or equal to 18 quarts

4 quarts equal one gallon... so 5 gallons is more than 18 quarts

There would be 4 quarts in 1 gallon.

4 × 5 = 20 quarts.

What would be greater, 20 quarts = 5 gallons, or 18 quarts.

It's clear that 5 gallons would be greater.

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.
