I kinda forgot my trig (kinda)
Ipatiy [6.2K]
\sec^2\theta=1+\tan^2\theta\implies \sec\theta=\pm\sqrt{1+\tan^2\theta}

Since \cos\theta>0 for 0, we have \sec\theta>0, so we take the positive root. Now,

\sec\theta=\sqrt{1+\left(\dfrac{12}5\right)^2}=\dfrac{13}5

- - -

\tan\theta=\dfrac{\sin\theta}{\cos\theta}
\cos^2\theta=1-\sin^2\theta

In the first quadrant, cosine is positive, so

\cos\theta=\sqrt{1-\sin^2\theta}

and in turn,

\sin\theta=\dfrac35\implies\cos\theta=\sqrt{1-\left(\dfrac35\right)^2}=\dfrac45
\implies\tan\theta=\dfrac{\frac35}{\frac45}=\dfrac34

- - -

In the previous problem, we had \cos\theta=\dfrac45, so we must have \tan\theta=\dfrac34, which means

\cot\theta=\dfrac1{\tan\theta}=\dfrac1{\frac34}=\dfrac43

Look at the picture I really need help understanding!​
o-na [289]

Answer:

I believe it is

1) yes

2) no

3) no

4)no

Step-by-step explanation:

It can only be a solution if you put the x in from the table into the x of the equation and the y in from the same ordered pair into the equation for y and if you get 1 for the fist equation it is a solution but you also have to get 7 for the second equation for it to fully be a solution. Also, you can go to desmos and enter the equations and then substitute the x's and y's... you will have to delete the =1 and =7 in order for the website to tell you what it equals.
