Jean throws a ball with an initial velocity of 64 feet per second from a height of 3 feet. write an equation and answer the questions below. show all your work for full credit. use the correct units with your answers

This is a problem of projectile motion. A projectile is an object you throw with an initial velocity and whose trajectory is determined by the effect of gravitational acceleration. The general equation in this case is described as:

Where:

So:

Finally, the equation is:

The rocket will reach the maximum height at the vertex of the parabola described by the equation . Therefore, our goal is to find at this point. In math, a parabola is described by the quadratic function:

So the x-coordinate of the vertex can be calculated as:

From our equation:

So:

So the rocket will take its maximum value after 1.99 seconds.

From the previous solution, we know that after 1.99 seconds, the rocket will reach its maximum, so it is obvious that the maximum height is given by . Thus, we can find this as follows:

So the maximum height the rocket will reach is 66.68ft

The rocket is in the air until it hits the ground. This can be found setting , so:

We can't have negative value of time, so the only correct option is and rounding to the nearest hundredth we have definitively:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

7 is the median   7.875 is the mean
