The complex conjugate of 13-21i is 1.3+ 2i.
In general the conjugate of a+bi is a - bi
and the conjugate of a-bi is a + bi
        
             
        
        
        
Answer:
710
Step-by-step explanation:
 
        
             
        
        
        
The reference angle is 
pi/3. 
At 180 it would be 9pi/3 so going past that is 10pi/3. 
        
             
        
        
        
I believe the answer should be approximately 6,147 because you would plug into the equation y=20,000(.95)^t, where t=23.
        
             
        
        
        
Hi i'd be glad to help you with this equation. 
basically all we have to do is find (65%) of 455*. 
65% of 455* = 295.75 
Next. 
455 + 295.75 = 750.75 
So, to check my work I have 750.75 miles in total. 
I have already driven 455 miles of 750.75 miles. 
Using subtraction we subtract our distance from our total. 
750.75 - 455 = 295.75 
So, in total your answer to this problem is (295.75) 
Hope this helps. 
Have a great day!
