Answer:

\boxed{\boxed{x=\dfrac{\pi}{3}\ \vee\ x=\pi\ \vee\ x=\dfrac{5\pi}{3}}}

Step-by-step explanation:

\cos(3x)=-1\iff3x=\pi+2k\pi\qquad k\in\mathbb{Z}\\\\\text{divide both sides by 3}\\\\x=\dfrac{\pi}{3}+\dfrac{2k\pi}{3}\\\\x\in[0,\ 2\pi)

\text{for}\ k=0\to x=\dfrac{\pi}{3}+\dfrac{2(0)\pi}{3}=\dfrac{\pi}{3}+0=\boxed{\dfrac{\pi}{3}}\in[0,\ 2\pi)\\\\\text{for}\ k=1\to x=\dfrac{\pi}{3}+\dfrac{2(1)\pi}{3}=\dfrac{\pi}{3}+\dfrac{2\pi}{3}=\dfrac{3\pi}{3}=\boxed{\pi}\in[0,\ 2\pi)\\\\\text{for}\ k=2\to x=\dfrac{\pi}{3}+\dfrac{2(2)\pi}{3}=\dfrac{\pi}{3}+\dfrac{4\pi}{3}=\boxed{\dfrac{5\pi}{3}}\in[0,\ 2\pi)\\\\\text{for}\ k=3\to x=\dfrac{\pi}{3}+\dfrac{2(3)\pi}{3}=\dfrac{\pi}{3}+\dfrac{6\pi}{3}=\dfrac{7\pi}{3}\notin[0,\ 2\po)

Find the distance between (-1,4) and (-1,12)
lukranit [14]

Answer:

8 units

Step-by-step explanation:

Since both are on the same place in terms of the x-axis, this makes it much easier. Just go from (-1,4) and move upwards upon the graph until your at (-1,12). You counted 8 units. *mic drop*

Help even tho it’s multiple choice make sure you are correct... I beg you lol

Answer:

The equation of the line is:

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

Therefore, option a is the correct answer.

Step-by-step explanation:

Given the points

  • (-2, 2)
  • (4, -1)

Finding the slope

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-2,\:2\right),\:\left(x_2,\:y_2\right)=\left(4,\:-1\right)

m=\frac{-1-2}{4-\left(-2\right)}

m=-\frac{1}{2}

As the point-slope form of the equation of the line is

y-y_1=m\left(x-x_1\right)

where m is the slope

substituting the values m=-\frac{1}{2} and the point (-2, 2)

y-y_1=m\left(x-x_1\right)

y-2=\frac{-1}{2}\left(x-\left(-2\right)\right)

y-2=\frac{-1}{2}\left(x+2\right)

y-2=-\frac{1}{2}\left(x+2\right)       ∵\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}

Add 2 to both sides

y-2+2=-\frac{1}{2}\left(x+2\right)+2

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

Hence, the equation of the line is:

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

Therefore, option a is the correct answer.
