36x2 + 49y2 = 1,764 The foci are located at

Vaselesa [24]

Answer:

The foci are located at: $(-\sqrt{13},0)$ and $(\sqrt{13},0)$

Step-by-step explanation:

The given conic has equation: $36x^2+49y^2=1764$

Divide each term by 1764

$\frac{36x^2}{1764}+\frac{49y^2}{1764}=\frac{1764}{1764}$

$\implies \frac{x^2}{49}+\frac{y^2}{36}=1$

$\implies \frac{x^2}{7^2}+\frac{y^2}{6^2}=1$

Comparing to:

$\frac{x^2}{a^2}+\frac{y^2}{b^2}=1$

We have a=7 and b=6

We use the relation $a^2-b^2=c^2$ to find c.

$\implies 7^2-6^2=c^2$

$\implies 49-36=c^2$

$\implies 13=c^2$

$\implies c=\pm \sqrt{13}$

The foci are located at: $(-\sqrt{13},0)$ and $(\sqrt{13},0)$
