                        A ski slope drops at an angle of 24 degrees with respect to the horizontal and is 500 m long. A 60 kg skier skis down from the top to the bottom of the slope. A.) Determine the change in gravitational potential energy of the skier+earth system. b.) If 20%...

                        I'm supposed to fill in a table. The angle of incedence in air is given (starting with zero degrees and then at 10, 20, 30, 40, 50 and 60 degrees. Using the sin function on my calculator, I'm supposed to figure out the angle of refraction in an acrylic bl...

                        Word problem: Wes saw fireworks at 28 degrees; Abby (who was standing 20 m away from him) saw the same fireworks at a 40 degree angle. Where was Abby standing? (The answer is 61.8m, but I don't know how to figure it out or sketch the triangle).

                        The formula for the area of a trapezoid is 1/2(b_1 + b_2)h where h = delta (x) Therefore, A = 1/2(4+k)2 + 1/2(k+8)2 + 1/2(8+12)2 = 54 Solving that equation yields k = 10.

                        Pretty much nothing. I'm really lost. I don't even know how to use my calculator with that SIN function.

                        Its 2/3 because if you do rise/run it is 8/12. 8/12 is equivelent to 2/3
