Answer:

y=-2/3x +1

Slope = The change in y over the change in x so to do this you can use the two points To find the change in y to be -1-3=4 And the change in x to be 3 -(-3)=6 so you get -4/6 which can be simplified to -2/3 Then to find the next part find the y intercept which is y=1 at x=0

Which of the following is NOT equal to sin pi/3

Yanka [14]

Answer:

D) $sin(\frac{4\pi }{3} ) = sin(\pi +\frac{\pi }{3} ) = -sin\frac{\pi }{3}$

Step-by-step explanation:

$sin(\frac{2\pi }{3} ) = sin ( \pi - \frac{\pi }{3} ) = sin\frac{\pi }{3}$

$cos (\frac{\pi }{6} ) = cos ( \frac{\pi }{2} - \frac{\pi }{3} ) = sin(\frac{\pi }{3})$

$cos (\frac{11\pi }{6} ) = cos ( \frac{3\pi }{2} + \frac{\pi }{3} ) = sin(\frac{\pi }{3})$

$sin(\frac{4\pi }{3} ) = sin(\pi +\frac{\pi }{3} ) = -sin\frac{\pi }{3}$

The graph of y = tan ⁡(x − π / 2) compared to the graph of y = tan ⁡x has:

vodomira [7]

Answer:

Last Option moved $\frac{\pi}{2}$ units right

Step-by-step explanation:

If we have a function f(x) and we want to move it horizontally then we make the transformation:

$y = f (x + h)$

If $h$ then the graph of f(x) moves horizontally h units to the right

If $h> 0$ then the graph of f(x) moves horizontally h units to the left.

In this case we have the function $y = tan (x)$ and the transformation is performed to obtain $y = tan(x- \frac{\pi}{2})$

Notice that in this transformation

$h$

<u><em>Then the graph of $y = tan (x)$ moves horizontally $\frac{\pi}{2}$ to the right</em></u>

Given cosα = −3/5, 180 < α < 270, and sinβ = 12/13, 90 < β < 180

torisob [31]

I got

$- \frac{6 3}{65}$

What we know

cos a=-3/5.

sin b=12/13

Angle A interval are between 180 and 270 or third quadrant

Angle B quadrant is between 90 and 180 or second quadrant.

What we need to find

Cos(b)

Cos(a)

What we are going to apply

Sum and Difference Formulas

Basics Sine and Cosines Identies.

1. Let write out the cos(a-b) formula.

$\cos(a - b) = \cos(a) \cos(b) + \sin(a) \sin(b)$

2. Use the interval it gave us.

According to the given, Angle B must between in second quadrant.

Since sin is opposite/hypotenuse and we are given a sin b=12/13. We. are going to set up an equation using the pythagorean theorem.

${12}^{2} + {y}^{2} = {13}^{2}$

$144 + {y}^{2} = 169$

$25 = {y}^{2}$

$y = 5$

so our adjacent side is 5.

Cosine is adjacent/hypotenuse so our cos b=5/13.

Using the interval it gave us, Angle a must be in the third quadrant. Since cos is adjacent/hypotenuse and we are given cos a=-3/5. We are going to set up an equation using pythagorean theorem,

$( - 3) {}^{2} + {x}^{2} = {5}^{2}$
