Answer:

She shaded area?

12 x 10 = 120

6 x 7 = 42

42 divided by 2 = 21

Now we subtract both areas:

120 - 21 = 99 of the shaded region.

Solve the trigonometric equation in the interval [0, 2π). Give the exact value, if possible; otherwise, round your answer to two
svp [43]

Answer:

θ∈{\frac{\pi }{8},\frac{5\pi }{8},\frac{9\pi }{8},\frac{13\pi }{8}}

Explanation:

The given equation is

sin(2\theta )-cos(2\theta )=0

\Rightarrow sin(2\theta )=cos(2\theta )\\\\\therefore \frac{sin(2\theta )}{cos(2\theta )}=1\\\\tan(2\theta )=1\\\\\therefore 2\theta =n\pi +\frac{\pi}{4}\\\\\therefore \theta =\frac{n\pi }{2}+\frac{\pi }{8}

Applying values on 'n' we obtain values of θ that beling to [0,2π)

For n=0, θ=\frac{\pi }{8}

For n=1, θ =\frac{5\pi }{8}

For n=2,θ =\frac{9\pi }{8}

For n=3,θ =\frac{13\pi }{8}

Graph the equation using the slope and y-intercept y = -x + 3
Ulleksa [173]

Answer:

<h3>Explained Below:</h3><h3 />

Step-by-step explanation:

Your y-intercept is a positive three, so your starting point would start on positive three on the y-axis. Since your slope is a negative one, your line should be heading towards the bottom right corner (much like your last question).

To find the next point on the graph, you need to go down one and over one. Or, one space.
