- When the shot whose path is shown by the red graph on the previous page is released at an angle of 65°, its height, g(x), in feet, can be modeled byg(x) =-0.04x2+2.1x+6.1,where x is the shot’s horizontal distance, in feet, from its point of release. Use this model to solve parts (a) through (c) and verify your answers using the red graph.a. What is the maximum height, to the nearest tenth of a foot, of the shot and how far from its point of release does this occur?b. What is the shot’s maximum horizontal distance, to the nearest tenth of a foot, or the distance of the throw?c. From what height was the shot released?arrow_forwardQ3-Please help me with this problem and needed all parts to be answered please, will be highly appreciated.arrow_forward3.

Thank you!arrow_forwardSolve the simultaneous equations y = 1 + 3x - x2 and y = 3 – x graphically. Plot your graphs for -1arrow_forwardA trough is 9 feet long and 1 foot high. The vertical cross-section of the trough parallel to an end is shaped like the graph of y=x8y=x8 from x=−1x=-1 to x=1x=1 . The trough is full of water. Find the amount of work in foot-pounds required to empty the trough by pumping the water over the top. Note: In this problem, use 62 pounds per cubic foot as the weight of water.arrow_forward1.
