R.A. Moyer of lowa State College found. in comprehensive tests carried out on 41 wet pavements, that the braking distance d(in feet) for a particular automobile traveling at v miles per hour was given approximately by
\(d=0.0212v^{\frac{7}{3}}\)
Approximate the braking distance to the ncarest foot for the car traveling on wet pavement at 70 miles per hour.

Using the given equation, substitute v=70 and solve for dd:
\(d=0.0212(70)^{\frac{7}{3}}\)
Use a calculator:
\(d≈428\rightarrow428 feet\)

Sheila is in Ms. Cai's class . She noticed that the graph of the perimeter for the "dented square" in problem 3-61 was a line . "I wonder what the graph of its area looks like ," she said to her teammates .
a. Write an equation for the area of the "dented square" if xx represents the length of the large square and yy represents the area of the square.
b. On graph paper , graph the rule you found for the area in part (a). Why does a 1st−quadrant graph make sense for this situation? Are there other values of xx that cannot work in this situation? Be sure to include an indication of this on your graph, as necessary.
c. Explain to Sheila what the graph of the area looks like.
d. Use the graph to approximate xx when the area of the shape is 20 square units.
