These three roots are sufficient to enable us to form a 3rd degree polynomial:
f(x) = (x+4)(x-4)(x-2) = (x^2 - 16)(x-2) = x^3 - 2x^2 - 16x + 32 (answer)
The third graph represents a function.
In a function, every input (x value) has <em>exactly</em> one output (y value). If even a single input has zero or two outputs, the graph does not represent a function.
A good way of testing this is using a vertical line. As you move a vertical line from left to right across a graph, it should always be touching exactly one point on the graphed line.
In this case, every graph fails this vertical line test except for the third graph, so the third graph represents a function.
Answer:
$204.98
Step-by-step explanation:
Step 1: Add both item cost

Step 2: Find the sales tax of the result

- Step 1: Convert 8% to fraction

- Simplify

- Step 2: Convert 189.80 to a fraction

- Step 3: Set it up

- Step 4: Cross divide

- Step 5: Multiply the result

Step 3: Add the result from the total cost of both items

The total cost of the hats and boots including sales tax is 204.98 dollars
Air? Unless you mean like a toy boat? IDK, I do know that huge ships like the Titanic are able to float because they have trapped oxygen. Think about if you're swimming; often when you hold your breath you float a bit better than if you were heavily breathing. Sorry i know its not alot to go off of, did i help you a little?
