Answer:

$area = 2(area \: of \: trapezium) - 2(area \: of \: triangle) \\ = 2( \frac{1}{2} h(a + b)) - 2( \frac{1}{2} bh) \\ = 4(4 + 6) - (4 \times 2) \\ = 40 - 8 \\ = 32 \: {ft}^{2}$

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 $-\frac {-4\sqrt 3 }9$

Simplify. (y3)5 · y4

igomit [66]

I'm assuming ya want us to simplify $(y^3)^5*y^4$

reemember some exponential rules

$(a^b)^c=a^{bc}$

$(a^b)(a^c)=a^{b+c}$

so

$(y^3)^5*y^4=$

$y^{15}*y^4=$

$y^{15+4}=$

$y^{19}$

You graph the function f(x)=-|×|-12

Firlakuza [10]

Answer:

See attachment

Step-by-step explanation:

We want to graph $f(x)=|x|-12$ on the interval -10 to 10.

Let $g(x)=|x|$ be the parent absolute value function.

We can easily graph $f(x)=|x|-12$ , if we use translation.

When the parent function is shifted downwards by 12 units, we obtain the graph of $f(x)=|x|-12$ .

The parent function is a v-shaped graph with vertex at the origin.

We shift the parent function down so that its vertex is now at (0,-12) to get the graph of $f(x)=|x|-12$ .

See attachment for the graph of $f(x)=|x|-12$ on the specified interval.
