If sin θ = 3 over 7 and tan θ < 0, what is the value of cos θ?

AnnZ [28]

$if\ \sin\Theta \ \textgreater \ 0\ and\ \tan\Theta \ \textless \ 0\ then\ \Theta\in\underbrace{(90^o;\ 180^o)}_{\left(\dfrac{\pi}{2};\ \pi\right)}\\\\therefore\ \cos\Theta \ \textless \ 0.$

$\text{Use:}\ \sin^2x+\cos^2x=1\\\\\left(\dfrac{3}{7}\right)^2+\cos^2\Theta=1\\\\\dfrac{9}{49}+\cos^2\Theta=1\ \ \ |-\dfrac{9}{49}\\\\\cos^2\Theta=\dfrac{40}{49}\to\cos\Theta=-\sqrt{\dfrac{40}{49}}\\\\\cos\Theta=-\dfrac{\sqrt{40}}{\sqrt{49}}\\\\\cos\Theta=-\dfrac{\sqrt{4\cdot10}}{7}\\\\\boxed{\cos\Theta=-\dfrac{2\sqrt{10}}{7}}$

“Each set below has 3 expressions. There is ONE expression in EACH set that DOES NOT BELONG. Try to find the expression that doe

SCORPION-xisa [38]

Answer:

Set 1: 3(2x)

Set 2: 1/2 (-4x)

Set 3: 2 (12x + 4y)

Step-by-step explanation:

Set 1: 3(x+2) and 3x+6 are the same//3(x+2) =3x+6

Set 2: 1/2 (2x - 6) and x - 3 are the same//1/2 (2x - 6) = x-3

Set 3: 24x + 8y and 8(3x + y) are the same//2x+8y = 8(3x + y)

A movie theater is located on a map of a city represented by a coordinate plane. The location of the movie theater is at (−4, 2)

Romashka [77]

See the graph

<h2>Explanation:</h2>

Remember to write complete questions in order to get good and exact answers. Here you haven't provided any option, but it's easy to plot this point on a coordinate system in order to know the location of the movie theater. We know that this theater is at the point:

$(-4,2)$

So let's plot this point in the cartesian plane:

The x-coordinate is -4
The y-coordinate is 2.

So the graph is shown below. Remember that the horizontal axis is called the x-axis while the vertical axis is called the y-axis.

x > 0 for the x-values to the right of the origin.

x < 0 for the x-values to the left of the origin.

y > 0 for the y-values above the origin

y < 0 for the y-values below the origin.
