Answer:
<em>The work done by the force is 42.4 Joules</em>
Step-by-step explanation:
The force F = 7 pounds
angle to the horizontal that the force acts ∅ = 30°
The object is moved a distance d = 7 feet
The coordinate (0 comma 0 )to (7 comma 0 ), indicates that the movement started from the origin, and is along the x-axis.
The work done by this force = F cos ∅ x d
==> 7 cos 30° x 7
==> 7 x 0.866 x 7 =<em> 42.4 Joules</em>
Answer:
Step-by-step explanation:
The formula for the sum of n terms of an arithmetic sequence is
aₙ = a₁ + (n-1)d
If a₁ = -40, d = -7, and n = 22
Answer:
x = 7 m and x = −7 m
Step-by-step explanation:
|x|−2+2=5+2
|x|=7
x= −7 and the only answer that has both of them is the last one
The answer is D, -3.
3 and -3 cancel each other out when added.
