In general, in polar coordinates (r, ω) = (-r, ω+π), because when you add π radians to an angle you are turning 180 degrees and then need to change the sign of the radius to preserve the original point.
Then (-5, π/4) = (5 , π/4 + π) = (5, 5π/4)
Answer: (5, 5π/4)
Answer: Ogro that is 2727
Step-by-step explanation:
Answer:
21 hours
Step-by-step explanation:
First, multiply 18 by 27 to represent the painting. You should get 486.
Then, subtract 486 from 738. You should get 252
Lastly, divide 252÷12. You should get 21.
Hope this helped!
Answer:
9 ^ (-15)
Step-by-step explanation:
9^-3/9^12
We know that a^b/ a^c = a^(b-c)
9^-3/9^12 = 9 ^(-3-12)
=9^(-15)
