Answer:
The graph should be stretched rather than become narrower.
Step-by-step explanation:
To figure this out, just create some example points.
At x = 0, your y-value will always be 0. But if you were to plug in the value 1, you would get a y-value of 1 in y=x^2, but a value of 0.5 in y=0.5x^2. If you were to plug in a value of 2, you would get a value of 4 in y=x^2, but a value of 2 in y=0.5x^2.
If you continue this pattern for a few more points, then plot them, you will see that adding a coefficient of 0.5 simply stretches the graph
I believe the correct answer is 29.3
In total, he ran 10,000 meters. The way you can find this is by finding how many meters are in a kilometer (which is 1,000), after that you need to convert everything to meters, so running 8km is now running 8,000 meters, sprinting 500 meters doesn't change, and climbing bleachers for 1.5km is now 1,500 meters.
If you add all of these numbers up you will get your answer of 10,000 meters
