{25 POINTS]

1 answer:

7 0

The point (3, -4) is on the terminal side of the Ø implies that the hypotenuse has a length of 5, by the pythagorean theorem.
Now recall cos<span>Ø = x / r where r is the hypotenuse.
So </span>cosØ = 3 / 5.

Q1: Identify the graph of the equation and write an equation of the translated or rotated graph in general form.

marin [14]

Answer:

C. hyperbola; $9x^2-25y^2-250y-850=0$

Step-by-step explanation:

The given conic has equation:

$9x^2-25y^2=225$

Divide through by 225.

$\frac{9x^2}{225}-\frac{25y^2}{225}=\frac{225}{225}$

$\frac{x^2}{25}-\frac{y^2}{9}=1$

This is a hyperbola centered at the origin.

The hyperbola has been translated from the origin to (0,5).

The translated hyperbola will have equation;

$\frac{(x-0)^2}{25}-\frac{(y-5)^2}{9}=1$

Multiply through by 225.

$9(x-0)^2-25(y-5)^2=225$

Expand

$9x^2-25(y^2-10y+25)=225$

$9x^2-25y^2+250y-625=225$

Rewrite in general form;

$9x^2-25y^2+250y-625-225=0$

$9x^2-25y^2+250y-850=0$

You are knitting a blanket. You want the area of the blanket to be 24 feet squared . You want the length of the blanket to be 2

Sauron [17]

Think of it this way: x multiplied by a number that is two more than x is y.
So, look at the factors. 3 and 8 wouldn't work, because 8 is 5 longer than 3. 1 and 24 wouldn't work, because 24 is 23 more than 1. 12 and 2 is also not going to work; 12 is 10 more than 2. What you have left is 4 and 6. 6 is 2 more than 4, and they both multiply to get 24.

So, the correct answer is 6 feet long and 4 feet wide.
