Answer:
8000π mm^3/s ≈ 25,133 mm^3/s
Step-by-step explanation:
The rate of change of volume is found by differentiating the volume formula with respect to time.
V = 4/3πr^3
V' = 4πr^2·r'
For the given numbers, this is ...
V' = 4π(20 mm)^2·(5 mm/s) = 8000π mm^3/s ≈ 25,133 mm^3/s
_____
<em>Additional comment</em>
By comparing the derivative to the area formula for a sphere, you see that the rate of change of volume is the product of the area and the rate of change of radius. This sort of relationship will be seen for a number of different shapes.
Answer: a 20% chance
Step-by-step explanation:
All you need to do is 2/10 = .2 = 20%
We do this because if 2 chose to read and there are 10 kids.
Answer:
6x - 11 feet
Step-by-step explanation:
Dale is standing (2x + 7) feet height from the base of the tower.
And the tower is given to be (8x - 4)feet tall.
We have to find the distance between Dale and the top of the tower.
Now, the distance between dale and the top of the tower = height of the tower - height of Dale = (8x - 4) - (2x + 7) = (6x - 11) feet. (Answer)
Answer:
ok so it would take more effort to lift the 1 newton that is 4 m
Step-by-step explanation:
Work is done when a an object with a certain weight is moved at a given distance;
It is the product of force and distance and therefore varies directly to both distance and force.
Work = Force × distance;
For a 4 N box 0.5 m;
Work = 4 × 0.5
= 2 Joules
For a 1 N box 4 m
Work = 1 × 4
= 4 Joules
Therefore, Lifting a 1 N box for 4 m, will take more work
hope this helps

have a nice day :D
Direct variation is when 
is the same for each coordinate.
