Hyperbola equation opening horizontally:
\frac{x^2}{a^2} - \frac{y^2}{b^2} = 1
Asymptotes:
y = \pm \frac{b}{a} x

'a' is distance vertex is from center --> a = 9
'c' is distance focus is from center  --> c = 15
a^2 + b^2 = c^2 \\  \\ b^2 = 15^2 - 9^2 = 144 \\  \\ b = 12

Asymptotes are:
y = \pm \frac{12}{9} x = \pm \frac{4}{3} x

How many different ways can the letters in the word objects be arranged?
DiKsa [7]
The best way to think of this is how many options there are for each letter. There are 7 possibilities for the first letter. Then there are 6 possibilities (out of the remaining letters) for the second latter. Then 5 possibilities for the next, and so on. The total number of possibilities will be 7x6x5x4x3x2x1, which equals 5,040. So there are 5,040 different ways to arrange 7 letter words.
