A line passes through the point ( -10, 4) and has a slope of 1/2

qwelly [4]

Answer:

$y-4=\frac{1}{2} (x+10)$

Step-by-step explanation:

Point-slope form: $y-y_1=m(x-x_1)$ when the given point is $(x_1,y_1)$ and the slope is $m$

$y-y_1=m(x-x_1)$

Plug in the point (-10,4)

$y-4=m(x-(-10))$

Two negatives make a positive

$y-4=m(x+10)$

Plug in the slope

$y-4=\frac{1}{2} (x+10)$

I hope this helps!

Given sin theta = 1/3 and 0 theta pi/2 find tan 2 theta

Kazeer [188]

Answer:

$\tan2\theta=\pm\dfrac{4\sqrt{2}}{7}$

Step-by-step explanation:

Given: $\sin\theta = \dfrac{1}{3}$

$0\leq \theta \leq \dfrac{\pi}{2}$

Theta lie in first quadrant.

Multiply both sides by 2

$0\leq 2\theta \leq \pi$

2theta lie in I and II quadrant.

$\tan2\theta$ is positive in I and negative in II quadrant.

$\sin\theta=\dfrac{1}{3}$

$\cos\theta=\dfrac{2\sqrt{2}}{3}$

$\sin2\theta=2\sin\theta\cos\theta$

$\sin2\theta=2\cdot \dfrac{1}{3}\cdot \dfrac{2\sqrt{2}}{3}=\dfrac{4\sqrt{2}}{9}$

$\cos2\theta=\pm \sqrt{1-\sin^22\theta}=\pm\dfrac{7}{9}$

$\tan2\theta=\dfrac{\sin2\theta}{\cos2\theta}$

$\tan2\theta=\pm\dfrac{4\sqrt{2}}{7}$

Hence, The value of $\tan2\theta=\pm\dfrac{4\sqrt{2}}{7}$
