Answer:
Balance of savings account at the end of 3rd month = $753.13
Step-by-step explanation:
Balance at the end of 1st month :
Principal = $250 , Time = 1 month , n = 12 , APR = 2.5%

Balance at the end of second month :
Principal = 250 + 250.52
= 500.52
Time = 1 month, APR = 2.5%, n = 12

Balance at the end of third month :
Principal = 250 + 501.56
= 751.56
Time = 1 month, APR = 2.5%, n = 12

Hence, Balance of savings account at the end of 3rd month = $753.13
I just guessed and it is 108
So, I'm going to break it down to help you understand it a bit more.
If it starts at (0,-2) and crosses through (1,0) that means it moved to the right once and up twice. Which means, that the slope will be 2. If it were one it would be to the right 1 up one, if it were 4 it would be to the right 1 up 4, and finally if it were 1/2 it would be to the right 2 up 1.
So, your answer is C. or 2.
Answer:
Step-by-step explanation:
think of complex numbers as going along the x axis for 5 and along the y axis for 12..... now do you know how to find the magnitude? think Pythagoras
