Answer:

<h2>Function is y = x.</h2><h2>Domain: $-3 \leq x \leq 2$ .</h2><h2>Range: $-5 \leq y \leq 4$ .</h2>

Step-by-step explanation:

In the given image, the line passes through (-1, -1) and (1, 1).

Let the equation of the line is $y = mx + c$ , where m is the tangent of the line and c is a constant.

Putting the co-ordinates of the points in the equation, we get $-1 = -m + c$ and $1 = m + c$

From the two equations we get, c = 0 and m = 1.

Hence, the function is y = x.

Domain is $-3 \leq x \leq 2$ .

Range is $-5 \leq y \leq 4$

Answer:

659.6 ft

Step-by-step explanation:

x = 140 / tan 23

x = 329.82(rounded to hundredth)

so total ground distance between the cables = 2x = 2(329.82) = 659.64 feet
