(7-(-1))^2 +(-2)^2=60 Answer should be B
To solve this problem you must apply the proccedure shown below:
1. You have the followin quadratic equation given in the problem above: <span>x^2+3x+1
2. Therefore, you have:
x^3+3x=-1
(b/2)^2=(3/2)^2=9/4
x^2+3x+9/4=-1+9/4
(x+3/2)^2=5/4
Therefore, as you can see, the answer is: </span>(x+3/2)^2=5/4
38.4/x=100/32.5
multiple both sides of the equation by x
38.4=3.07692307692*x
divide both sides by the big number to get x
38.4/(big number)=x
x=12.48
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
