The polar form of the given complex number is:
[tex]W = \sqrt{12}* e^{-i*0.52}[/tex]
How to get the polar form of the complex number?
Here we have:
W = -3 + √3i
To get the polar form we first need the module of W it is:
|W| = √( (-3)^2 + (√3)^2) = √12
And now we need to find the bearing, that is given by the Arctangent of the quotient between the imaginary part and the real part.
Arctan(√3/-3) = -0.52 rad
Then the polar form is:
[tex]W = |W|*e^{-i*0.52} = \sqrt{12}* e^{-i*0.52}[/tex]

T-shirts that usually sell for $28.99 are on sale
for $17.39. What percent off are they?
Answer: i think it is 46.38 %
Step-by-step explanation: add both numbers ( decimals) and just put the percentage. hope this will help u stay safe :)
Answer:
38.3%
Step-by-step explanation:
We have two equations to find the answer.
1. Discount = OG Price * Discount by 100%
2. Final Price = OG Price - Discount
So fill in the first equation :
Discount = 28.99 * 38.3/100
Discount = 28.99 * 0.38
Saved = $11.10
Now for the second equation :
Final Price = 28.99 - 11.10317
Final Price = $17.89
Therefore the discount is 38.3%

The vegetable garden has 95 ripe plants. The number of tomatoes is 16 fewer than twice the number of squashes. How many of each vegetable are ripe?
Answer:
Tomatoes = 39.5
Squash = 55.5
Step-by-step explanation:
T (tomatoes) = S - 16
S + T = 95
we plug it in now
S + (S - 16) = 95
2s = 95 + 16
2s = 111
s = 55.5??
hm. Let's go with it
T = 55.5 - 16
T = 39.5
39.5 + 55.5 = 95
