Answer:
No
Step-by-step explanation:
y^2 = x^2 + 5
Rewriting
y^2 - x^2 = 5
This is a hyperbola
We can use the vertical line test to show that it is not a function since a vertical line passes through more than one point.
Answer:
-1/3
Step-by-step explanation:
By using this equation: 
, we can find the slope of the line. We get -1/3.
This is a right triangle. To find the length of the hypotenuse a^2 + b^2 = c^2.
21^2 + 18^2 = c^2
441 + 324 = c^2
765 = c^2

Ferromagnetic (for the purposes of this page, at least) means that they will align themselves with a magnetic field. That being the case, iron filings are an excellent way to display the magnetic field of one or multiple bar magnets.
