It's 6 because 13 times 6 -3 is 75. i'm pretty sure that's how you would do it... lol
The percentage increase is about 1%.
The explanation is using the higher or new value and divide it by the inceptive value which equals about 1%
9.80 divided by 9.69 = 1%
Height of the water increasing is at rate of
<h3>How to solve?</h3>
With related rates, we need a function to relate the 2 variables, in this case it is clearly volume and height. The formula is:
There is radius in the formula, but in this problem, radius is constant so it is not a variable. We can substitute the value in:
Since the rate in this problem is time related, we need to implicitly differentiate wrt (with respect to) time:
In the problem, we are given
So we need to substitute this in:
Hence, Height of the water increasing is at rate of
