an ellipse has a center at the origin, a vertex along the major axis at (13, 0), and a focus at (12, 0). What is the equation of
yan [13]
Hi, as the elipce has a center at the origion and tha major distance is the axis

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

But, 

c = 12        Distance of focus

a = 13   ->  Major distance

b = ?  -> 

But, 

\\ b^2 + c^2 = a^2
 \\ 
 \\ b^2 + 12^2 = 13^2
 \\ 
 \\ b^2 + 144 = 169
 \\ 
 \\ b^2 = 169 - 144
 \\ 
 \\ b^2 = 25
 \\ 
 \\ b =  \sqrt{5} 
 \\ 
 \\ b = 5



Then,


\\  \frac{x^2}{(13)^2} +  \frac{y^2}{(5)^2} = 1
 \\ 
 \\ or
 \\ 
 \\  \frac{x^2}{169} +  \frac{y^2}{25} = 1

Can someone help with this please
crimeas [40]

Answer:

3^2

Step-by-step explanation:

\frac{3^8*\:3^4}{3^2*\:3^8}

Apply Exponent rule: a^b\cdot \:a^c=a^{b+c}

\frac{3^{12}}{3^8* \:3^2}

\frac{3^{12}}{3^{10}}

Apply exponent rule: \frac{x^a}{x^b}=x^{a-b}

3^{12-10}=3^2
