In a basket ball game, Tamara made 16 out of 20 shots from the free throw line. What percent of her shots did she make?

You divide how many shots she made by how many shots she did in total 16/20= .8
=80%

She made 80% of her shots! You can just go in your calculator and divide 16 by 20 to get 0.8 which equals 80%. Hope this helps!!

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.

If the diameter is 8 than the radius is 4 because 2r or 2*radius equals the diameter. 4*2=8. 8/2=4.
