given: sin theta= 2/3 and theta is in the second quadrant; evaluate the following expression. sin2theta
andre [41]

The value of \sin(2\theta) is -\frac {-4\sqrt 3 }9

<h3>Sine ratio </h3>

The sine ratio is given as:

\sin(\theta) = \frac23

<h3>Trigonometry</h3>

In trigonometry, we have the following ratio

\sin^2(\theta) + \cos^2(\theta) = 1

Substitute \sin(\theta) = \frac23 in the above equation

\frac 23 + \cos^2(\theta) = 1

Collect like terms

\cos^2(\theta) = 1 -\frac 23

Evaluate

\cos^2(\theta) =\frac 13

Take square roots

\cos(\theta) =\pm\frac 1{\sqrt 3 }

Rationalize

\cos(\theta) =\pm\frac {\sqrt 3 }3

From the question, \theta is in the second quadrant, and cosine is negative.

So, we have:

\cos(\theta) =-\frac {\sqrt 3 }3

In trigonometry, we have:

\sin(2\theta) = 2\sin(\theta)\cos(\theta)

So, we have:

\sin(2\theta) = 2\times \frac 23 \times -\frac {\sqrt 3 }3

\sin(2\theta) =  -\frac {-4\sqrt 3 }9

Hence, the value of \sin(2\theta) is -\frac {-4\sqrt 3 }9

Graph 3x +4y=12 please
earnstyle [38]

To help us to graph the 3x + 4y = 12, we can isolate y

\begin{gathered} 3x+4y=12 \\  \\ 4y=12-3x \\  \\ y=\frac{12}{4}-\frac{3}{4}x \\  \\ y=3-\frac{3}{4}x \end{gathered}

Therefore it's a line with equation

y=3-\frac{3}{4}x

We have y = 3 when x = 0, and x = 4 when y = 0, therefore
