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:
11 years old
Step-by-step explanation:
Maggie's age is x
Maggie's brother = 4x - 7
The sum is 48
x + 4x - 7 = 48
5x - 7 = 48
5x = 55
x = 11
2x-4y=8
2x=4y+8
x=2y+4
^^^^^^^
