First, you would create an equation for this problem.
-27 + 13

Now, all you would have to do is solve it.
-27 + 13 = -14

By 2 pm the temperature was -14 degrees.

I hope this helps!

What is the equation of a circle centered at the origin with radius 20.. i cant find the answer and i even tried?

KIM [24]

General equation of a circle with centre (h, k) is given by:

$(x - h)^{2} + (y - k)^{2} = r^{2}$

Now, the origin is the centre and radius is 20, so substituting these points in yields:
$x^{2} + y^{2} = 20^{2}$
$x^{2} + y^{2} = 400$
