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>
By factoring the expression the answer is (3x-2)(x+4). Hope that is helpful.
No need for the diagram (though it helps)
P(AUB) = P(A) + P(B) - P(A and B),
P(A) = 0.61 - 0.41 + 0.18 = 0.38
So, D!!

Important: Please express exponents properly: -2x^2 Correct
-2x2 Not correct
Rewrite <span>(-2x2 -6x + 7) - (3x3 - 5x + 14)
as
</span><span>- 2x^2 -6x + 7
</span><span>- (3x^3 - 5x + 14)
__________________
Even better, write each power of x in its own column:
</span>- 2x^2 -6x + 7 - 2x^2 -6x + 7
- 3x^3 + 5x -14 - 3x^3 + 5x -14
