Answer:

W = 19600 N m

Step-by-step explanation:

W = force * distance

The force is the weight times gravity since it is hanging down

W = 40 kg* 9.8 m/s^2 * 50m

    19600 kg m^2/s^2

A newton is  kg m/ s^2

W = 19600 N m

The sum of all angles in a regular octagon is 1080 degrees. Because all sides are the same (regular octagon), all of the eight angles are the same too, so we simply divide 1080 by 8 and that is the solution.

1080/8 = 135

A line is represented by the equation y = x + 2. Suppose the slope of the line was doubled and the value of the y-intercept was
Hitman42 [59]

Answer:

A.y=2x+1

Step-by-step explanation:

y = x+2

This is in the form y= mx+b

where m is the slope and b is the y intercept

m=1  we are doubling it

m=2

The y intercept is 2, we are dividing by 2

2/2 =1

b=1

y = mx+b

y = 2x+1
