The quadratic function y(t) = 13.5t - 4.9t2 gives the distance y, in meters, a golf ball travels in the vertical direction in t seconds. Graph the function on the grid by plotting the zeros of the function and several other points to fill out the shape of the curve. Use the graph to approximate the time at which the golf ball reaches its maximum height.

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

one set of data has more variation than the other. hope this !
