Write an equation of the line that passes through (-1,7) and is perpendicular to the line y=-1/8x -1

y = 8x + 15

Step-by-step explanation:

Step 1: Find slope of perpendicular line

Take the negative reciprocal of the 1st equation

m = 8

y = 8x + b

Step 2: Find b

7 = 8(-1) + b

7 = -8 + b

b = 15

Step 3: Rewrite perpendicular equation

y = 8x + 15

5.5

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
