NEED QUICK HELP.

Mathematics

Hello!

The equation for an exponential deprecation model like this is y = a(1-r)^{x}, where a is the starting value, x is the number of years passed, and r is the amount the value deprecates each year.

We know what a and r are: a = 1600, as that is the original cost of the computer, and r = .18, as that's how much it decreases by. Substitute these two into the equation.

We get y = 1600(1-.18)^{x}. Now, subtract 1 - .18 to get our final answer.

y = 1600(.82)^{x} is therefore the final model.

Hope this helps!

Normal form [see attachment]
musickatia [10]

I just did one of these. I guessed that normal form is


x \cos \phi + y \sin \phi -  p = 0


Here' that's


x (\sqrt{3}/2) + y (1/2) - 10 = 0


\sqrt{3} x + y - 20 = 0


Choice b
