consider the running track which consists of 2 straight paths each measuring 84 meters in length and 2 semicircles with diameter. what is the diameter in meters, if the distance around the track is 400 meters

The answer is 127.32

Step-by-step explanation:

400= Pi multiplied Diameter

D=   400/Pi= 127.32

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.
