A swimming pool is 20 ft wide, 40 ft long, 3 ft deep at the shallow end, and 9 feet deep at its deepest point. If the pool is be

Using implicit differentiation, it is found that the water level is rising a rate of 0.001 ft/sec.

The volume of a pool of length l, width w and height h is given by:

$V = lwh$

Applying implicit differentiation, the rate of change of the volume is given by:

$\frac{dV}{dt} = wh\frac{dl}{dt} + lh\frac{dw}{dt} + lw\frac{dh}{dt}$

Neither the width nor the length changes, hence $\frac{dl}{dt} = \frac{dw}{dt} = 0$ , and:

$\frac{dV}{dt} = lw\frac{dh}{dt}$

We are given that:

$\frac{dV}{dt} = 0.3, l = 20, w = 40$ , hence:

$\frac{dV}{dt} = lw\frac{dh}{dt}$

$0.8 = 20(40)\frac{dh}{dt}$

$\frac{dh}{dt} = \frac{0.8}{800}$

$\frac{dh}{dt} = 0.001
$

Water level is rising at rate of 0.001 ft/sec.

1. 3 x 2 = 6 2/3 x 2 = 4/3 which is 1 whole and 1/3 so the answer is 6 + 1 1/3 = 7 1/3
2. 3 1/2 x 4 1/7 = 58
3. 1/6 x 4 you only times the first number so 4/6 which is simplified is 2/3
4.
5. 4 -:- 2 = 2 2/7 you only divide the first number (the 2 which makes it 1/7)
Hope this helps I will finish number four in a few minutes but this is it in the mean time
