now, b is -3, and a is 3
or in rectangular if you wish, y = -3 and x = 3.... on what quadrant is "y" negative and "x" positive? well, the 4th quadrant
so, using our reference angle, that'd be
so, let's use the first one
![\bf (3,3i)\implies \begin{array}{llll} r[cos(\theta)+i\ sin(\theta)]\\\\ 3\sqrt{2}\left[ cos\left( \frac{7\pi }{4} \right)+i\ sin\left( \frac{7\pi }{4} \right) \right] \end{array}](https://tex.z-dn.net/?f=%5Cbf%20%283%2C3i%29%5Cimplies%20%0A%5Cbegin%7Barray%7D%7Bllll%7D%0Ar%5Bcos%28%5Ctheta%29%2Bi%5C%20sin%28%5Ctheta%29%5D%5C%5C%5C%5C%0A3%5Csqrt%7B2%7D%5Cleft%5B%20cos%5Cleft%28%20%5Cfrac%7B7%5Cpi%20%7D%7B4%7D%20%5Cright%29%2Bi%5C%20sin%5Cleft%28%20%5Cfrac%7B7%5Cpi%20%7D%7B4%7D%20%5Cright%29%20%5Cright%5D%0A%5Cend%7Barray%7D)
Answer:
10400km
Step-by-step explanation:
We know that the scale on a map is 1cm for every 400km. So to find the actual distance for 26cm on the map, we take 26 multiplied by 400km. This gives 10400km.
First:
Subtract 5 on each side of the equals sign to cancel it out. You should get 13x=144.
Next:
Divide 13 from each side of the equals sign to get x by itself.
Answer:
X=11.0769230769. You may need to round it up to 11.08 or 11.1 depending on how your teacher normally has you answer
Answer: 5 and 7.
Step-by-step explanation: I’m sorry I don’t know what kind of equation to do but I’ll show how I got the answer if that’s what you mean.
First I made a list of numbers that when multiplied equal 35
Then I went through the list and took out all the options that were not one number being 2 more than the other.
The only option left is 5 x 7 (5*7)
what kind of equation do you want? Like 5*7 = 35 and 5 + 2 = 7?
Your answer would be 4000000000 your welcome :D
I think.....
