Four joggers start at the same point; Ryan, Megan, Ethan, Ari. For each runner write a multiplication equation that describes their journey.

a. Ryan runs for 15 seconds at 6.2 meters per second. What is his finish point?

b. Megan runs for 20 seconds and finishes at 400 meters. What is her velocity?

c. Ethan runs for 25 seconds at -6.4 meters per second. What is his finish point?

d. Ari runs for 15 seconds and finishes at -285 meters. What is her velocity?

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
