C = 2 x pi x r
divide each side by 2 x pie to get r by itself.
45/(2(3.14)) = r
r = 7.17
Graph of y = -3/2x - 7 has a slope of -3/2.
For perpendicular lines the product of the slopes is -1.
m1m2 = -1
-3/2m2 = -1
m2 = -1/(-3/2) = 2/3
The required equation,
y - (-2) = 2/3(x - 3)
y + 2 = 2/3x - 2
y = 2/3x - 4
C. 26.14
you just have to subtract rope B from rope A and you’ll get your answer :)
10/5 =2
7-2+4^2 =5+16=21
2*21=42
