Find the volume of the tank:

Volume = 1 x 4 x7 = 28 cubic feet.

Divide number of fish by volume:

18/28 = 9/14 fish per cubic foot.

Answer:

0.643 fish / cubic foot to the nearest thousandth.

Step-by-step explanation:

The volume of the tank = 1 * 4 * 7

= 28 ft^3.

The population density = the number of fish / the volume of the water

= 18/28

= 0.643.

There are no restrictions on the domain of - 2x - 5, thus

domain is all real numbers

Describe how the graph of the equation relates to the graph of y = x2.<br> f(x) = -x + 5)2
Kobotan [32]

Answer:

Step-by-step explanation:

It's y = x^2, not y = x2.  The graph of y = x^2 is a parabola with vertex (0, 0) and which opens up.

The graph of y = (x + 5)^2 has the same shape as that of y = x^2, but has been translated 5 units to the left.
