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.

On the coordinate plane below, what is the length of AB? A coordinate plane is shown with a rectangle with the following points

love history [14]

The length of AB wit the coordinate (-6, 5) and (8,5). is 14 units

<h3>Distance between two points</h3>

A rectangle is a quadrilateral with 4 sides and angles

Taking the length of AB.

Since AB is slant line, the length of AB will be determined using the distance formula as shown;

D = √(-6-8)² +(5-5)

D = √(-14)²

D = AB = 14 units

Hence the length of AB wit the coordinate (-6, 5) and (8,5). is 14 units
