Locate a point c on the x-axis such that ac+bc is minimized. c=). the endpoints of ab are:

1) a(1,4) and b(4,-1)
2) a(-3,2) and b(-6,-4)
3) a(-2,3) and b(-4,0)
4) a(1,-3) and b(-1,1)

i really need , i have no clue what i am doing. : -)

Your answer is C

Step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
