Math
The horizontal range, R, is modeled by this formula: R(x)=(v^2*sin2(x))/32 The initial velocity (v) is 90ft per second. The ball is pitched at an angle of x degrees with the horizontal. When x=26 degrees, the ball travels 200ft. At what other value of x will the ball travel 20...

Geometry
Two forces are pushing on an object, one at 12 lbs of Force and one at 5.66 lbs of Force. The angle between them is 35° (each is 72.5 from horizontal, such that the forces make a v with the object in the center). 17. What is the total Force on the object? 18. What is the s...
