Tikiro places a wrench on a nut and applies a downward force of 32 pounds to tighten the nut. If the center of the nut is at the origin, the force is applied at the point (0.65, 0, 0.3). Find the torque.

Step-by-step explanation:

Assuming "downward" is in the -k direction.

Torque is the cross product of the radius vector and the force vector.

τ = r × F

τ = (0.65 i + 0.3 k) × (-32 k)

τ = 20.8 j

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
