Answer:
![2228 \: {ft}^{2}](https://tex.z-dn.net/?f=%202228%20%5C%3A%20%20%7Bft%7D%5E%7B2%7D%20)
Step-by-step explanation:
Required flooring cover
= Area of the school playground
= Area of square with side 40 ft + Area of semicircle with radius (40/2) i.e. 20 ft
![= {(40)}^{2} + \frac{1}{2} \times 3.14 \times {(20)}^{2} \\ \\ = 1600 + \frac{1}{2} \times 3.14 \times 400 \\ \\ = 1600 + 3.14 \times 200 \\ \\ = 1600 + 628 \\ \\ = 2228 \: {ft}^{2}](https://tex.z-dn.net/?f=%20%3D%20%20%7B%2840%29%7D%5E%7B2%7D%20%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%203.14%20%5Ctimes%20%20%7B%2820%29%7D%5E%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%201600%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%203.14%20%5Ctimes%20400%20%5C%5C%20%20%5C%5C%20%20%3D%201600%20%2B%203.14%20%5Ctimes%20200%20%5C%5C%20%20%5C%5C%20%20%3D%201600%20%2B%20628%20%5C%5C%20%20%5C%5C%20%20%3D%202228%20%5C%3A%20%20%7Bft%7D%5E%7B2%7D%20)

Because in both graphs the shaded region is above the curve, the correct option is C.
<h3>
Which pair of inequalities is graphed?</h3>
On the graph we can see two parabolas, such that the y-intercepts of these are:
y = 6
y = -4
So we just need to find the pair of options with these y-intercepts, and noticing that for both cases, we must have:
y > parabola.
Because both shaded regions are above the parabolas.
The only option that meets these requirements is option C. Where there is a mistake, as you can see both curves have dashed lines, and always when we have dashed lines we should use the symbols > or <, while in that option we have a ≥ symbol

Answer:
The last graph.
Step-by-step explanation:
The last graph because it shows the continum of time, and it shows him getting closer to the school (decrease in distance), then it shows him picking up Janet (staying constant), then it shows him going back home to grab his books (increase in distance), all as time goes on.
The median as a measure of center since his data is constant.
