Answer:
1.) different, subtract, 14
2.) same, add, -33
3.) same, add, -70
4.) different, subtract, 0
5.) different, subtract, -10
6.) different, add, 12
7.) same, subtract, 3
8.) different, subtract, -4
9.) different, subtract, -4
10.) 14
11.) Mark has more, he has $14 more
12.) 9
13) -13 - 12 = -25
14) 200 - 40 = 60
15) 12 - 3 = 8
8+5+8=21 coins in total.
8/21*7/20=
56/420=
2/15. Hope this helps, and PM me if something's not clear!
An ordered pair is written as (x, y)
P(-3) = 18
The -3 is the x value and the 18 is the y value
Answer: (-3,18)
Answer:
The complex number 
has Cartesian form
.
Step-by-step explanation:
First, we need to recall the definition of 
when 
is a complex number:
.
Then,
. (I)
Now, recall the definition of the complex exponential:
.
So,
(we use that 
.
Thus,
Now we group conveniently in the above expression:
.
Now, substituting this equality in (I) we get
.
Thus,
![\exp\left(\cos(2+3i)\right) = \exp\left(\cosh 3\cos 2\right)\left[ \cos(\sinh 3\sin 2)-i\sin(\sinh 3\sin 2)\right]](https://tex.z-dn.net/?f=%5Cexp%5Cleft%28%5Ccos%282%2B3i%29%5Cright%29%20%3D%20%5Cexp%5Cleft%28%5Ccosh%203%5Ccos%202%5Cright%29%5Cleft%5B%20%5Ccos%28%5Csinh%203%5Csin%202%29-i%5Csin%28%5Csinh%203%5Csin%202%29%5Cright%5D)
