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.

Sin 3A = cos (A – 70ᵒ), where A is an acute angle then<br> A = ________________ ᵒ.
romanna [79]

Answer:

A = 40°

Step-by-step explanation:

\sin 3A =  \cos (A – 70ᵒ) \\  \\  \cos(90 \degree -  3A) =  \cos (A – 70ᵒ) \\   \{\because \: \cos(90 \degree -   \theta) =  \sin \theta \} \\  \\ (90 \degree -  3A) =   (A – 70ᵒ)  \\  \\ 90 \degree  + 70ᵒ  =   3A  +  A  \\  \\ 160 \degree = 4A \\  \\ A =  \frac{160 \degree}{4}  \\  \\ \huge \red{ \boxed{A =  40 \degree}}

What does the graph of y=(x + 2)(x + 1)(x - 3)2 do near the point (3,0)?
IRINA_888 [86]

Check out the graph below. We see that (3,0) is a root or x intercept. More specifically, the graph only touches the x axis at this point, rather than cross over (in contrast to a root like (-2,0) ). We say that the root here is of multiplicity 2. The multiplicity is due to the exponent of 2 over the (x-3) factor.

You can also say that the graph is decreasing on the left side of (3,0) and then it bounces off the root x = 3 to increase afterward. In this region, the graph never goes below the x axis.

You cannot combine any the terms because x and y are two different variables. that is the most simplified you can get.
