A ball is launched from a platform. The equation for the ball's height h at time t seconds after launch is h(t)= -16t^2+153.6t +393.12, where h is in feet. What is the initial height of the ball before launch?

The initial height of the ball before launch is 393.12 feet.

Step-by-step explanation:

The ball's height (), in feet, as a function of time (), in seconds, is represented by . The initial height of the ball before launch is the height of the ball evaluated at :

The initial height of the ball before launch is 393.12 feet.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
