Mathematics

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

On a hot day, a fan has a mark on the tip of one blade. The equation y
stellarik [79]
<h3>Answer:  5 cm</h3>

===================================================

Explanation:

Recall that the range for cosine is from -1 to 1, including both endpoints. The smallest cosine value is what we're after, since we want the height to be as small as possible (to allow the blade be closest to the table).

Effectively, this means we replace the cos(x) with -1 so that it's as small as possible. Then we compute to get:

20*cos(x)+25

20*(-1) + 25

-20 + 25

5

The height of the fan tip is 5 cm when it is the closest to the table.

Side note: On the flip side, the furthest away the fan tip can get is 20*(1) + 25 = 45 cm. Therefore, the range of y values is 5 \le y \le 45
