Ariel threw a ball from the height of 6 feet into a pond. The function h (t)= –16t2 + 48t + 6 is used to calculate the amount of time the balls in the air before it hits the ground. How long was the ball in the air? How many solutions does this quadratic function have? PLEASE HELP ME

What are the relative frequencies to the nearest hundredth of the columns of the two-way table?

Need on this one asap im almost done with this subject
