Solve the problem.Two recording devices are set 2200 feet apart, with the device at point A to the west of the device at point B. At a point on a line between the devices, 300 feet from point B, a small amount of explosive is detonated. The recording devices record the time the sound reaches each one. How far directly north of site B should a second explosion be done so that the measured time difference recorded by the devices is the same as that for the first detonation?

Solve the problem.A projectile is fired from a height of 6.2 feet with an initial velocity of 174 ft/sec at an angle of 46° with the horizontal. The parametric equations for the path of the projectile are x = (174 cos 46°)t, and y = 6.2 + (174 sin 46°)t - 16t2,where x and y are in feet and t is in seconds. Find the height of the projectile after 4 seconds. Round your answer to the nearest tenth of a foot.
