Answer:

6

Step-by-step explanation:

Substitute a = 2 , b = 4 into the expression

\frac{b^2-2a}{a}

= \frac{4^2-2(2)}{2}

= \frac{16-4}{2}

= \frac{12}{2}

= 6

The zebra mussel, Dreissena polymorpha, filters particulate organic carbon (POC) from water
Temka [501]

The number of milligrams per liter of POC were in the bay when the zebra mussels were first introduced is 0.4 milligrams per liter.

The expression is an equation

<h3>What is an equation?</h3>

An equation is a mathematical expression that shows the relationship between two quantities.

<h3>How to find  how many milligrams per liter of POC were in the bay when the zebra mussels were first introduced?</h3>

Now, since the concentration, c, of POC (in milligrams per liter) remaining in a particular bay m months after the introduction of a population of zebra mussels can be estimated using the following equation c = 0.4 - 0.9m

Now, to find  how many milligrams per liter of POC were in the bay when the zebra mussels were first introduced, this would be the initial value of m at 0 months.

So, substituting m = 0 into the equation, we have

c = 0.4 - 0.9m

c = 0.4 - 0.9(0)

c = 0.4 - 0

c = 0.4 milligrams per liter

So, the number of milligrams per liter of POC were in the bay when the zebra mussels were first introduced is 0.4 milligrams per liter.

A prism with a base that is a regular hexagon
Katyanochek1 [597]

Answer:

Look at explanation

Step-by-step explanation:

The surface area (x^2) that you will be provided as the base is made from the formula (3\sqrt(3)/2)s^2. s is the length of one side of the hexagon. In order to get surface area, you will also be provided the height of the prism. From there, set x^2=(3\sqrt(3)/2)s^2 and solve for s. Then multiply s * the height of the prism *8. Then, add 2x^2 to that value for total surface area/
