Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

For $x\leq -2$ -----> the interval is (-∞,-2]

$f(x)=-3$

For $-2 < x \leq 1$ -----> the interval is (-2,1]

$f(x)=x$

For $x > 1$ -----> the interval is (1,∞)

$f(x)=2$

The local carnival grounds are in the shape of a rectangle. The area of the grounds is 0.125 square mile. The length of the grou

Sliva [168]

Answer:

Step-by-step explanation:

Width = x

Length = 2x

Area of the ground = 0.125 square mile

length * width = 0.125

2x * x = 0.125

2x² = 0.125

x² = $\frac{0.125}{2}\\\\$

= 0.0625

$x^{2}=\frac{625}{10000}\\\\x=\sqrt{\frac{625}{10000}}\\\\ x=\frac{25}{100}\\\\x=0.25$

Width = 0.25 miles

Length = 2* 0.25 = 0.50 miles
