If the area of a room is 132.9 square feet and one side of the room is 10.9 feet, how long is the other side of the room?
Ghella [55]

Answer:

The other side is about 12.2 feet

Step-by-step explanation:

The area is found by multiplying length times width. So, since you already have one of the sides of the room, you just divide the area by by that side. 132.9 ÷ 10.9 = 12.2

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

How do you do simplify this -9 -11
zheka24 [161]

Answer:

-9 + -11=-20

Step-by-step explanation:

Since subtracting is the same as addition of the oppositie, just putting a negative symbol is easier because you are only working with negative numbers, instead of one negative and one positive.

Did that help?
