Look at the conversion table below. kg lbs 1: 2.2 2: 4.4 3: 6.6 4: 8.8 5: 11.0 6: 13.2 7: 15.4 8: 17.6 9: 19.8 You are asked to lift something that is 15 kg. How many pounds is it? lbs You pick up something that weighs 48.4 lbs. How many kilograms is this? kg

The answer is -pie over 2

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.

Iam not good at math i wish i could

I'm sorry your problems aren't showing up on my end but i'd love to sorry
