A cable is installed around two edges of the rectangular field that is 860 feet long and 340 feet wide, as shown below. Suppose
raketka [301]

Answer:

<em>a. 2,520,000.00</em>

<em>b. $1,942,017.51</em>

<em>c. $577,982.49</em>

Step-by-step explanation:

<u>Distances in a Rectangle</u>

a.

Running the cable along the edges of the field would need a total length of 860 ft + 340 ft = 1,200 ft of cable. The unit cost of the cable is $2,100 per foot, thus the cost of the total lenght of cable was 2,100*1,200= $2,520,000.

b. If the cable ran along the diagonal, the distance must be computed by

D=\sqrt{x^2+y^2}

where x = 860 ft and y = 340 ft, thus

D=\sqrt{860^2+340^2}=924.77

D = 924.77 ft. The cost of the cable would be 2,100*924.77= $1,942,017.51

c. The savings if the cable were installed along the diagonal of the field instead of around the edges of the field would be

$2,520,000 - $1,942,017.51 = $577,982.49

Y=9x+3&gt;&gt; is this true, false, or open??
AfilCa [17]
First you have to know the value of either x or y. If x is 2, and y is 20, it would be false.

But if x is 2 and y is 21, it would be true.

So, the equation is open!
