The answer to this is common sense, chill out man. I was joking.

Ohh.....so did I pass?? 

I may not be able to explain any better...but I will try!

Here is just a graph of the point (21, 48).

Theta is the angle that a line from the origin to the point makes with the positive x-axis.

The second one is the same graph, just with some more markings on it.

Look at the second picture. This is just a right triangle! And...in every right triangle,

tan = opposide / adjacent

So..

tan θ = 48/21

θ = atan(48/21)

θ ≈ 66.371º

And we can use the Pythagorean theorem to find the hypotenuse...which is r.

21² + 48² = r²

r = \(\sqrt{441+2304}\approx52.393\) ...just as you found!

Whats wrong Penny??

I KNOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It was a quiz!!!!!!!!!!!!

itz 3,077,056,399

btw i b different guest

79^5 = 3,077,056,399

You can type it into the calculator on the home page just like that: 79^5

no no no

I think this must be a parabola we are dealing with. The general form of a parabola in vertex form is:

y = a(x - h)² + k, where (h, k) is the vertex.

We know the vertex...h = -4, and k = -1

y = a(x + 4)² - 1

We know x = -6 and y = -13 makes the equation true. So plug these in and solve for a.

-13 = a(-6 + 4)² - 1

-12 = a(-2)²

-12 = 4a

-3 = a

Now we know h, k, and a. So the equation is:

y = -3(x + 4)² - 1

I forgot to mention that the original coordinates are rectangular, sorry!

\(\frac{15}{18}=\frac{x}{100}\\~\\ 100*\frac{15}{18}=x \\~\\83\frac13=x\)

So...15 is      \(83\frac13\%\)      of 18...Guest #2 is right
