  a)  t = 2 seconds

  b)  6.05 meters

Step-by-step explanation:

I prefer a graph for questions like this, but I have attached a table, too. Here, the table is created using a graphing calculator to evaluate the function. A spreadsheet can do this nicely, too.

The maximum height occurs at t=0.9 seconds, and the ball hits the ground at a time that is slightly more than double that, 2.0 seconds.

The maximum height is 6.05 meters.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram
