Atwenty-five foot ladder just reaches the top of a house and forms an angle of 41.5° with the wall of the house. how tall is the house? round your answer to the nearest 0.1 foot.

So to find this we must use cos(41.5 degrees) so the equation is cos(41.5)=x/25 we times both sides by 25. We also find out what cos 41.5 is in this step. so 0.75x25 = x. Therefore x=18.8. the house is 18.8 feet tall

The answer is harsh laws are needed to control the society

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.
