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.

11 more than y is equal to 7

fomenos

We first have to come up with an equation that satisfies this. The equation is y+11=7.

Then we subtract 11 from both sides. y+11-11=7-11.

Then we get the answer y=-4.

The graph of f(x) = x2 was transformed to create the graph of g(x) = (x − 7.5)2. Which of these describes this transformation?

QveST [7]

Answer:

A. A horizontal shift to the right 7.5 units

Step-by-step explanation:

Replacing x with x-7.5 shifts the graph 7.5 units to the right.

In general, g(x) = f(x-h)+k will shift h units right and k units up. In this problem there is no vertical shift.
