(1+cos2x)/(1-cos2x) = cot^2x

sesenic [268]

We will turn the left side into the right side.

$\dfrac{1 + \cos 2x}{1 - \cos2x} = \cot^2 x$

Use the identity:

$\cos 2x = \cos^2 x - \sin^2 x$

$\dfrac{1 + \cos^2 x - \sin^2 x}{1 - ( \cos^2 x - \sin^2 x)} = \cot^2 x$

$\dfrac{1 - \sin^2 x + \cos^2 x }{1 - \cos^2 x + \sin^2 x} = \cot^2 x$

Now use the identity

$\sin^2 x + \cos^2 x = 1$ solved for sin^2 x and for cos^2 x.

$\dfrac{\cos^2 x + \cos^2 x }{\sin^2 x + \sin^2 x} = \cot^2 x$

$\dfrac{2\cos^2 x}{2\sin^2 x} = \cot^2 x$

$\dfrac{\cos^2 x}{\sin^2 x} = \cot^2 x$

$\cot^2 x = \cot^2 x$

The state fair charges $14 for

Scrat [10]

Answer:

$s=6r+14$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$s=mr+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

$m=\$6\ per\ ride$

The y-intercept is equal to

$b=\$14$

substitute the given values

$s=6r+14$

An emu that measures 22 inches in height is 14 inches less than 2 times the height of a stuffed toy canary. What is the height o

OlgaM077 [116]

Answer: The height of the stuffed toy canary is 18 inches so Jesus is right.

Step-by-step explanation:

We can represent the first statement by the equation 22= 2x - 14 where x is the height of the stuffed toy canary so solve for x

22 = 2x -14 Add 14 to both sides

+14 +14

36 = 2x Divide both sides by 2

x = 18

Jesus is right.
