Explain how you would graph the point (2,-6) and which quadrant it would be in.<br> Nour answer

Gwar [14]

Answer:

It would he in quadrant 4

Step-by-step explanation:

First off you should know 2 represents x and -6 represents y since it is (x,y). To graph this we must find positive 2 on the x line which in the horizontal line. Then we must point -6. Since this term is negative, we move 6 points down since down is negative and up is positive.

I don't even know how to figure this out. I don't have a formula for this

yuradex [85]

Answer:

$\sin\theta=\dfrac{15}{17}$

$?=15$

Step-by-step explanation:

Use the trigonometry formula

$\cos^2\theta+\sin^2\theta=1$

You are given that

$\cos \theta=\dfrac{8}{17}$

Substitute into the first formula

$\left(\dfrac{8}{17}\right)^2+\sin^2\theta=1\\ \\\dfrac{64}{289}+\sin^2\theta=1\\ \\\sin^2\theta=1-\dfrac{64}{289}=\dfrac{289-64}{289}=\dfrac{225}{289}\\ \\\sin \theta=\pm \dfrac{15}{17}$
