Jane launched a toy rocket into the air. The rockets path is projected as h(t) = -2t2 + 4t + 2, where h is the height in feet and t is the time in
seconds.

$12. that is my answer.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

- "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."

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it
