Take the coordinates on each line and find their related slopes:
Slope formula m= (y₂-y₁)/(x₂-x₁)
1st . The two given coordinates of the LOWER line are: (-1,-1) and (1,-2)
them m = (-2+1)/1+1) = -2/2 = -1
2nd. The two given coordinates of the HIGHER line are: (-1,2) and (1,1)
them m = (1-2)/(1+1) = -1/2
3rd. The two given coordinates of the SECANTE are: (1,0) and (2,2)
them m = (2-0)/(2-1) = 2/1 = 1
We notice that the 1st line has m = -1 and the 3rd (secant), m = 1, then only the 1st line and the secant are perpendicular because the product of their slope is equal - 1 (this is the condition to have perpendicular lines)
Answer:
That would be option C.
Step-by-step explanation:
I literally just took the quiz and got it right.
The probability you won't be a hobbit is 2/3, and the probability you won't use an umbrella is 4/5.
The radius of that circle would be 6 feet. 70/360 is going to be .19444(repeated) and the Math:Fraction of that is 7/36. Pi*Radius²=36 means the radius is 6.
