Find the vertices and foci of the hyperbola with equation (x-5)^2/81 -(y-1)^2/144 = 1
vesna_86 [32]
Given the equation of an hyperbola in the form:
\frac{(x-a)^2}{b^2}- \frac{(y-c)^2}{d^2}=1
Then the focus of the hyperbola is (\pm\sqrt {b^2+d^2},0)
Compute like this:
\sqrt{81+144}=15
So the two focus points are (\pm15,0)
The vertices are given by the formula: (\pm a,0)
We deduce the two vertices of the given hyperbola: (\pm9,0)
since \sqrt{81}=9

Answer:

-\dfrac{2}{17} + \dfrac{9}{17}i

Step-by-step explanation:

(2 + i) \div (1 - 4i) =

= \dfrac{2 + i}{1 - 4i}

= \dfrac{2 + i}{1 - 4i} \times \dfrac{1 + 4i}{1 + 4i}

= \dfrac{(2 + i)(1 + 4i)}{(1 - 4i)(1 + 4i)}

= \dfrac{2 + 8i + i + 4i^2}{1 + 16}

= \dfrac{2 + 9i - 4}{17}

= \dfrac{-2 + 9i}{17}

= -\dfrac{2}{17} + \dfrac{9}{17}i
