Solve the problem.A satellite dish is in the shape of a parabolic surface. Signals coming from a satellite strike the surface of the dish and are reflected to the focus, where the receiver is located. The satellite dish shown has a diameter of 8 feet and a depth of 3 feet. The parabola is positioned in a rectangular coordinate system with its vertex at the origin. The receiver should be placed at the focus src="https://sciemce.com/media/4/ppg__10625191630__f1q291g3.jpg" alt="" style="vertical-align: -4.0px;" />
The value of p is given by the equation 
How far from the base of the dish should the receiver be placed?

The function s gives the displacement (in ft) of an object as a function of time (in seconds). Calculate values of the average velocity for the given values of t and find the instantaneous velocity at the indicated value of t by noting the limit of the average velocities.s = 5t - 4; when t = 4; use values of t of 3.5, 3.9, 3.99, 3.999
A. Average velocities: 19.5, 19.9, 19.99, 19.999
v = 20 ft/s
B. Average velocities: 20, 20, 20, 20
v = 20 ft/s
C. Average velocities: 5, 5, 5, 5
v = 5 ft/s
D. Average velocities: 4.5, 4.9, 4.99, 4.999
v = 5 ft/s
Find an equation that shifts the graph of f by the indicated amounts.f(x) = x2 + 2x - 7; left 2 units, down 11 units
A. y = (x + 2)2 + 2(x - 2) - 18 B. y = (x - 2)2 + 2(x + 2) + 18 C. y = (x - 2)2 + 2(x - 2) + 18 D. y = (x + 2)2 + 2(x + 2) - 18
