What is the equation of the following graph?

This is a vertical ellipse since it's taller than it is wider. That means that y is the transversal axis, aka the major axis. The formula for this type of ellipse is

where h and k are the center of the ellipse and a is the number of units from the center along the minor axis to the outside of the ellipse and b is the number of units from the center along the major axis to the outside of the ellipse. Here, our h and k are, respectively, (0, -3), a = 1 and b = sqrt(3). Fitting those values into our formula we have the equation as

.

That's your answer!

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
