Step-by-step explanation:
Answer: an improper fraction
Step-by-step explanation: An improper fraction is a fraction that is larger than 1 7/3 is larger than one because 7, the numerator is larger than the denominator so 7/3 is an improper fraction
4x-y=3
-y=-4x+3
y=4x-3
Since it is perpendicular, the slope must be a negative reciprocal.
therefore the slope is -x/4
Substituting the x and the y values (to find the b)
6=5/4+b
6-5/4=b
19/4=b
therefore the equation of the line is
y=-x/4+19/4
Answer:

Step-by-step explanation:
The work is define as the integral of the force times distance. So we have:

Now, we can write the force in terms of density.

V is the volume (V=2*1*1=2 m³)
So the work will be:

The limit of integration is between 0 and 0.5 because we want to pump half of the water out of the aquarium.


I hope it helps you!
