Andrew has a fish tank in the shape of a rectangular prism, and he needs to know the volume of water necessary to fill the tank.

Alex

Answer:

The correct option is D.

Step-by-step explanation:

Domain is the set of all posible

The volume of a rectangular prism is

$V=\text{Base area}\times height$

where,

$\text{Base area}=length\times width$

Dimensions can not be negative. So, the width and volume are always positive.

From the graph it is noticed that

In interval $(-\infty, -5)$ , width and volume is negative, so $(-\infty, -5)$ interval is not the domain.

In interval (-5,0), width is negative, so (-5,0) interval is not the domain.

In interval (0,3), volume is negative, so (0,3) interval is not the domain.

In interval $(3,\infty)$ , width and volume is negative, so $(3,\infty)$ interval is not the domain.

Therefore the correct option is D.

Can u plz help me with this one

pshichka [43]

6x-2(3x+2)=-4.
that would reduce after distributing the negative two to the parentheses as:
6x-6x-4=-4.
that can be reduced because the x’s cancel out. when you move the -4 over by adding 4, those cancel out too. therefore, the answer is infinite. hope this helps!!
