Through: (5, -5), perp, to y= 2x + 2

y = -1/2x - 2.5 or y = -0.5x - 2.5

Step-by-step explanation:

You want to first find the slope of this perpendicular lie which is the negative reciprocal.

Original slope = 2

New slope = -1/2

So now you want to plug in the (5,-5) to find the y-intercept

y=-1/2x+b

-5 = -1/2 (5) + b

-5 = -2.5 + b

b = -2.5

So, your new equation is y = -1/2x - 2.5

y = -1/2x - 2.5

Step-by-step explanation:

y=-1/2x+b

-5 = -1/2 (5) + b

-5 = -2.5 + b

b = -2.5

y = -1/2x - 2.5

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
