If an object is dropped from a height of 85 feet, the function h(t)=-16t^2+85 gives the height of the object after t seconds. Approximately, when will the object hit the ground? A...
the formula s(t) = −16t2 + v0t. (a) If the object hits the ground after 12 seconds, find its initial velocity v0. v0 = ft/sec (b) Find...
two tennis balls are dropped, one from a height of 16 feet and the other from a height of 100 feet. write the two height functions and use a graphing caculator to compare their graphs.
Complete the square to write the function in f(x) = a(x − h)2 + k form. Determine the vertex and the axis of symmetry of the graph of the function. f(x) = 2x2 + 12x + 10...
Complete the square to write the function in f(x) = a(x − h)2 + k form. Determine the vertex and the axis of symmetry of the graph of the function. f(x) = x2 + x − 6 &nbs...
Complete the square to write the function in f(x) = a(x − h)2 + k form. Determine the vertex and the axis of symmetry of the graph of the function. f(x) = x2 + 4x − 5 equation...
a baseball player hit a ball with an upward velocity of 46ft/s. its height h in feet after t seconds is given by the function h=-16t2 +46t+6
part b) if a 4 by 4 by 4 cube is assembled the same way. how many small cubes will have exactly one face painted? c) 5 x 5 x 5??? 6 x 6 x 6???
A) y=-4x^2+8 B) y=4x^2-8 C) y=8-4x^2 D) y=4x^2+8
The cost C of manufacturing x wheels at Ravi's Bicycle Supply is given by the function C(x)=0.5x^2-170x+25,850 What is the minimum cost of manufacturing wheels? Do...
A person standing close to the edge on top of a 60-foot building throws a ball vertically upward. The quadratic function h(t) = -16 t^2 + 68 t + 60 models the ball's height about the ground,...
A tour operator believes that the profit P, in dollars, from selling x tickets is given by P(x)= 50x − 0.25x2. Using this model, what is the maximum profit the tour operator can expect?
The height s, in feet, of a rock thrown upward at an initial speed of 64 ft/s from a cliff 49 ft above an ocean beach is given by the function s(t) = −16t2 + 64t + 49, where t is the time...
For the quadratic function (x)=-1/3(x+6)(x+6)+3, tell whether the graph opens up or down; wider or narrower; vertex and axis. Ok so I think I have the idea for this Vertex:...
Suppose you throw a ball straight up from the groin with a velicity of 80 ft/s. As the ball moves upward, gravity slows it. Eventually the ball begins to ball back to the ground. The height h...
