A football is punted into the air. It’s height h, in meters, after t seconds is given by the equation h=-4.9t^2+24.5t+1. Find the maximum height of the ball to one decimal place. PLEASE HELP MY TEACHER WONT TEACH ME(with explanation please)

step-by-step explanation:

me! what did you put for this question?

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

can i see the following ?
