Solve the problem.A baseball player hit a baseball with an initial speed of 140 feet per second at an angle of 40° to the horizontal. The ball was hit at a height of 3 feet off the ground. Find parametric equations that describe the motion of the ball as a function of time. How long is the ball in the air? When is the ball at its maximum height? What is the distance the ball traveled?
A. x = 107.24t, y = -16t2 + 90.02t + 3 5.659 sec, 2.813 sec, 1021.812 feet B. x = 107.24t, y = -16t2 + 90.02t + 3 5.659 sec, 2.813 sec, 606.871 feet C. x = 107.24t, y = -16t2 + 90.02t + 3 5.593 sec, 2.813 sec, 599.793 feet D. x = 107.24t, y = -16t2 + 90.02t + 3 11.319 sec, 2.813 sec, 1213.85 feet
Determine whether the graph is that of a function. If it is, use the graph to find its domain and range, the intercepts, if any, and any symmetry with respect to the x-axis, the y-axis, or the origin.
A. function domain: all real numbers range: {y|-1 ? y ? 1} intercepts: (-?, 0), (0, 0), (?, 0) symmetry: origin B. function domain: {x|-? ? x ? ?} range: {y|-1 ? y ? 1} intercepts: (-?, 0), (0, 0), (?, 0) symmetry: origin C. function domain: {x|-1 ? x ? 1} range: {y|-? ? y ? ?} intercepts: (-?, 0), (0, 0), (?, 0) symmetry: none D. not a function
