Ajump rope held stationary by two children, one at each end, hangs in a shape that can be modeled by the equation h=0.01x^2 - x + 28, where h is the height (in inches) above the ground and x is the distance (in inches) along the ground measured from the horizontal position of one end. how close to the ground is the lowest part of the rope?

3 inches.

Step-by-step explanation:

As the equation has a positive coefficient of , the graph is a parabola that open up. So, the minimun height value will be the y value of the vertex. Now, the vertex is

where b=-1 and a=0.01. Then,

Then, the lowest part of the rope (50) is 3 inches close to the ground.

25
