Answer:

The hyperbolas which open horizontally are:

(x+2)^2/3^2-(2y-10)^2/8^2=1

(x-1)^2/6^2-(2y+6)^2/5^2=1

Step-by-step explanation:

A hyperbola with equation of the form:

(x-h)^2/a^2-(y-k)^2/b^2)=1 opens horizontally

Then, the hyperbolas which open horizontally are:

(x+2)^2/3^2-(2y-10)^2/8^2=1

(x-1)^2/6^2-(2y+6)^2/5^2=1

Answer:

\frac{(x-2)^2}{3^2}-\frac{(2y-10)^2}{8^2}=1

and

\frac{(x-1)^2}{6^2}-\frac{(2y+6)^2}{5^2}=1

Step-by-step explanation:

There are 2 types of hyperbolas:

Horizontal:

\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1

Vertical:

\frac{(y-k)^2}{a^2}-\frac{(x-h)^2}{b^2}=1

If the x term is positive then parabola is horizontal.

If the y term is positive then parabola is vertical.

so, only first two equations are in which x term is positive.

hence, equations are

\frac{(x-2)^2}{3^2}-\frac{(2y-10)^2}{8^2}=1

and

\frac{(x-1)^2}{6^2}-\frac{(2y+6)^2}{5^2}=1

In a U. S . Poll 8 out of 12 citizens said they were happy with the job Obama is doing. If 126 people were surveyed...
Solnce55 [7]

8 out of 12 people were happy.

8/12 reduces to 2/3 of the people were happy.

Multiply the total people surveyed by 2/3:

126 x 2/3 = (126 x 2) /3 = 252/3 = 84

84 people were happy.
