Write each complex number in rectangular form.
hram777 [196]
Hello,

A)
cos 135°=- cos 45°=-√2/2
sin 135°=sin45°=√2/2
2(cos 135°+i sin 135°)=-√2 + i*√2

B)
cos 120°=-cos 30°=-√3 /2
sin 120°=sin 30°=1/2

3(cos 120° + i sin 120)=-3/2*√3 +i*3/2

C)
cos (5π/4)=-cos (π/4)=-√2 /2
sin (5π/4)= -sin(π/4)=-√2 /2
5(cos (5π/4)+i sin (5π/4))=-5/2*√2 +i *5/2*√2

D)
cos(5π/3)=cos(π/3)=√3 /2
sin (5π/3)=-sin(π/3)=-1/2

4(cos(5pi/3)+i sin (5pi/3))
=2√3- 2*i

ALL I NEED HELP WITH IS WITH PART D, HOW DO I GET THAT
Sauron [17]

Step-by-step explanation:

<u>Step 1:  Factor the equation</u>

f(x) = -16x^{2} + 22x + 3\\f(x) = -(8x + 1)(2x - 3)

<u>Step 2:  Find the x-intercepts of the graph of f(x)</u>

<u />-8x - 1 + 1 = 0 + 1\\-8x / -8 = 1 / -8\\x = -1/8

2x - 3 + 3 = 0 + 3\\2x / 2 = 3 / 2\\x = 3/2

<u>Step 3:  Describe the end behavior of the graph of f(x)</u>

Since the function is to the power of 2, that means that it is a parabola.  And since the leading coefficient is negative, means that the arrows will be pointing down therefore, the end behavior of this graph is as x goes to infinity, f(x) goes to negative infinity and as x goes to negative infinity, f(x) goes to negative infinity.

<u>Step 4:  What are the steps you would use to graph f(x)</u>

The first step that I would do is factor the equation.  Then I would find the x-intercepts of the graph and plot them on the graph.  I would then plug in 0 for all of the x values to get the y intercept.  After doing that I would get the vertex using the vertex formula plotting it on the graph.  Finally, I would connect all of the dots together to form the graph of the equation.
