1. a child launches a toy rocket from the top of a slide at the park. suppose the equation
-16t^2+28t+8=0
can be used to find how many seconds it will take for the rocket to hit
the ground.
a. write the equation in factored form.
b. use the zero product property to solve the equation. show all the steps needed
to find both answers.
c. explain how the solution relates to this situation.

answer: i think the answer is etheir c or d but i don't know which one but have a good day!

step-by-step explanation:

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man

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."
