What is the center of the hyperbola whose equation is (y+3)^2/81-(x-6)^2/89=1?

xxMikexx [17]

We have been given an equation of hyperbola $\frac{(y+3)^2}{81}-\frac{(x-6)^2}{89}=1$ . We are asked to find the center of hyperbola.

We know that standard equation of a vertical hyperbola is in form $\frac{(y-k)^2}{b^2}-\frac{(x-h)^2}{a^2}=1$ , where point (h,k) represents center of hyperbola.

Upon comparing our given equation with standard vertical hyperbola, we can see that the value of h is 6.

To find the value of k, we need to rewrite our equation as:

$\frac{(y-(-3))^2}{81}-\frac{(x-6)^2}{89}=1$

Now we can see that value of k is $-3$ . Therefore, the vertex of given hyperbola will be at point $(6,-3)$ and option D is the correct choice.

Find the degree of this polynomial? <br> 13-4ab+5a^3b

Anastasy [175]

Let's take a peek of each term, to be specific, the exponent of the variables only, to see what degree each term is

$\bf 13-4ab+5a^3b\quad 
\begin{cases}
13\impliedby \textit{no variable, degree is 0}\\
4ab\to 4a^1b^1\impliedby \textit{1+1, degree is 2}\\
5a^3b\to 5a^3b^1\impliedby\textit{3+1, degree is 4}
\end{cases}$

so...which term has the highest degree? well, that one, is the degree of the polynomial
