Solve the problem.A projectile is fired from a height of 7.5 feet with an initial velocity of 195 ft/sec at an angle of 52° with the horizontal. The parametric equations for the path of the projectile are x = (195 cos 52°)t, and y = 7.5 + (195 sin 52°)t - 16t2,where x and y are in feet and t is in seconds. Determine the maximum height reached by the projectile. Round your answer to the nearest tenth of a foot.
A. 383.9 ft B. 376.4 ft C. 745.4 ft D. 368.9 ft
Provide an appropriate response.Use the method of Lagrange multipliers to find the critical points of f(x, y, z) = 4x + 2y - 4z subject to the constraint x2 + y2 + z2 =1.
What will be an ideal response?
Write the equation of the graph after the indicated transformation(s). The graph of y =
