Since 0, -180 is the rotation and if you look at the other rotations like 90, 180 the first rotation would be different. so 0, 180 is the same as 0, -180 because they both would be a full rotation of a 180 rotation. The first number "0 ," would have to be the same.

Let z= -5 sqrt 3/2 + 5/2i and w=1 + sqrt 3i

MrRissso [65]

$z=-\dfrac{5\sqrt3}2+\dfrac52i=5\left(-\dfrac{\sqrt3}2+\dfrac12i\right)=5e^{i5\pi/6}$

$w=1+\sqrt3\,i=2\left(\dfrac12+\dfrac{\sqrt3}2i\right)=2e^{i\pi/3}$

b. Not exactly sure how DeMoivre's theorem is relevant, since it has to do with taking powers of complex numbers... At any rate, multiplying $z$ and $w$ is as simple as multiplying the moduli and adding the arguments:

$zw=5\cdot2e^{i(5\pi/6+\pi/3)}=10e^{i7\pi/6}$

c. Similar to (b), except now you divide the moduli and subtract the arguments:

$\dfrac zw=\dfrac52e^{i(5\pi/6-\pi/3)}=\dfrac52e^{i\pi/2}$

The sum of two consecutive integers is no more than 209. what is the larger of the two integers? enter your answer in the box.

puteri [66]

209÷2=104.5
104.5 is the number between the two consecutive integers, therefore the first number would be 104 and the other would be 105
104+105=209

Given the functions f and g, explain why you cannot find f⋅g.

Delvig [45]

We can't write the product because there is no common input in the tables of g(x) and f(x).

<h3>Why you cannot find the product between the two functions?</h3>

If two functions f(x) and g(x) are known, then the product between the functions is straightforward.

g(x)*f(x)

Now, if we only have some coordinate pairs belonging to the function, we only can write the product if we have two coordinate pairs with the same input.

For example, if we know that (a, b) belongs to f(x) and (a, c) belongs to g(x), then we can get the product evaluated in a as:

(g*f)(a) = f(a)*g(a) = b*c

Particularly, in this case, we can see that there is no common input in the two tables, then we can't write the product of the two functions.

Cos 4θ − cos 2θ = sin θ

hichkok12 [17]

$cos(4\theta) - cos(2\theta) = sin(\theta)$
$-2sin(\frac{4\theta + 2\theta}{2})sin(\frac{4\theta - 2\theta}{2}) = sin(\theta)$
$-2sin(\frac{6\theta}{2}sin\frac{2\theta}{2}) = sin(\theta)$
$-2sin(3\theta)sin(\theta) = sin(\theta)$
$\frac{-2sin(3\theta)sin(\theta)}{-2sin(\theta)} = \frac{sin(\theta)}{-2sin(\theta)}$
$sin(3\theta) = -\frac{1}{2}$
$sin^{-1}[sin(3\theta)] = sin^{-1}(-\frac{1}{2})$
$3\theta = -30$
$\frac{3\theta}{3} = \frac{-30}{3}$
$\theta = -10$

PLEASE HELP 20 POINTS IF YOU HELP AND WILL BE MRAKED BRAINLEST!!!!!!!!!!!!!!!!The two-way table below shows the number of studen

Yuliya22 [10]

Your answer is the last option, 6.

We can work this out by looking for the total of people that like tennis in the table, and subtracting it from the total amount of people that like baseball.

This gives us a total of 46 people that like baseball, subtract 40 people that like tennis, and 46 - 40 = 6.

I hope this helps!
