Walt grew 10 centimeters in 1 year he is now 1.6 meters tall how tall was he 1 year ago

He is 1.5 1 meter is 100 centimeters so therefore 1.6 meters would be 160 centimeters if he grew 10 centimeters a year and is currently 1.6 or 160 centimeters subtract 10 centimeters and its 1.5 meters or 150 centimeters.

Walt was 1.5 meters tall. There are 100 centimeters in 1 meter. So when you convert the 10 centimeters to meters, you get 0.1 meter. You can then subtract 1.6 - 0.1 to get 1.5 meters.

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.
