A bird caught a fish on the waters surface and flew in a straight line diagonal to the water for 100 yards. Then, it dropped the fish straight down. The fish landed at a spot 50 yards away horizontally from the point where the bird caught it.
The bird flies at an angle of degrees from the water, and its height from the ground when it drops the fish is yards.

What is the inverse of the function f(x)=4x+8

Solve for x where 0 equation: cot^2x+2cotx+1=0

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
