You have been asked to build a scale model of a restaurant out of bottle caps. the restaurant is 20 feet tall. your scale is 2.4 cm : 1 foot. you are out of bottle caps, and decide to use popsicle sticks instead. you measure them, and they are 15.2 cm tall. how many popsicle sticks tall will your model be?

Ok, so here you can do it a few different ways, and since I am the kind of person that does things to her logic, I will do it my way.

Ok, so here it is telling you that you are going to build a scale model of a building. Doesn’t matter what kind of building. In this case, it’s a restaurant. It tells you that your scale is 2.4

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.

It is b as the correct answer is 0.088, you are able to work these out on a calculator or without a calculator if you type in the exact sum that is given for harder questions like these!
