Answer:

The equation of hyperbola : $\frac{y^{2} }{49 } - \frac{x^{2} }{32 }$

Step-by-step explanation:

Given - This hyperbola is centered at the origin.

Foci: (0,-9) and (0,9) Vertices: (0,-7) and (0,7)

To find - Find its equation.

Solution -

We know that,

Equation of Hyperbola is represented by

$\frac{y^{2} }{a^{2} } - \frac{x^{2} }{b^{2} }$

Now,

Given that,

Foci : F(0, -9) and F'(0, 9)

So,

c = 9

And

Vertices : A(0,-7) and A'(0,7)

So,

a = 7

Also, we know that,

c² = a² + b²

⇒b² = c² - a²

⇒b² = 9² - 7²

⇒b² = 81 - 49

⇒b² = 32

So,

The equation of hyperbola becomes

$\frac{y^{2} }{49 } - \frac{x^{2} }{32 }$

A share of stock in the Lofty Cheese Company is quoted at 25 1/4. Suppose you hold 30 shares of that stock, which you bought at

baherus [9]

Since each share was purchased when it was still quoted at 20 1/4, then when the stock value increases, it gains (25 1/4 - 20 1/4) = $5.00 for each stock. Since you're to sell 30 shares of your stock, that means you'll be making a profit of (30 x 5 ) = $150.00. Thus, the answer is C<span>.</span>
