Solve: sec b cosec b=2 cosec b

Answers

Answer:

b = 60° or 300°

Step-by-step explanation:

We can solve the equation $sec b csc b=2 csc b$ in terms of sin and cos as follows:

We can write sec b and csc b in terms of sin and cos:

$\sf sec \:b = (1)/(\:cos\: b)$

$\sf csc b = (1)/(sin \:b)$

Substituting these expressions into the equation, we get:

$\sf (1)/(cos b) \cdot (1)/(sin b) = 2 \cdot (1)/(sin b)$

Multiplying both sides of the equation by sin b cos b, we get:

$\sf 1 = 2\cdot (cosb\cdot sinb)/(sinb)$

$\boxed{\sf (sin b)/(sinb)=1}$

so,

$\sf 1 = 2\: cos b$

Dividing both sides of the equation by 2, we get:

$\sf (1)/(2) =cos b$

$\sf cos 60^\circ = cos b$

Since cos is positive in 1st and 4th quadrant, so

$\sf cos 60^\circ \:\:or\:\:cos(360^\circ-60^\circ)= cos b$

Therefore, the solutions to the equation $sec b \csc b=2 \csc b$ for b is 60° or 300°

hello

Step-by-step explanation:

A teacher wrote the equation 3y + 12 = 6x on the board. For what value of b would the additional equation 2y = 4x + b form a system of linear equations with infinitely many solutions?b = –8
b = –4
b = 2
b = 6

Answers

Answer: First option.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept

We need to write each equation in Slope-Intercept form:

First equation

$3y + 12 = 6x\n\n3y=6x-12\n\ny=2x-4$

Second equation

$2y = 4x + b \n\ny=2x+(b)/(2)$

Since, by definition, a system of linear equations has infinitely many solutions when the lines are the same, we can say that:

$y=y\n\n2x-4=2x+(b)/(2)$

Then, solving for "b", we get:

$-4=(b)/(2)\n\n(-4)(2)=b\n\nb=-8$

Answer:

-8

Help me find the equation for the dimensions of a window, please!

Answers

On the sheet, it's not even asking you for the dimensions.
It's just asking you to set up the equation that you would use
to find the dimensions. That's a great way to do it, because
nobody actually needs the answers, the whole thing is only
meant to help you learn HOW to find them.
==========================================
Call the width of the window 'W' .

We know that the length is 5 feet more than the width, so the length is (W + 5).

The area is (length times width).

Area = (W + 5) times (W).

36 = (W + 5) W

36 = W² + 5W

Subtract 36 from each side:

W² + 5W - 36 = 0

That's choice-4 .
