You subtract the withdraw amount and the ATM fee from your balance and that would give you your check register balance
These are known as simultaneous equations,,
2x + y= -3 take this as 1st equation
x-2y=-4 take this as 2 nd equation
therefore x - 2y= -2 should be multiplied by 2 inorder to cut off 2x and 2x from the first and second equations.
by multiplying we get 2x - 4y = -4
therefore 3rd equation should be substracted from 1st equation...
now, 2x -4y - 2x -y = -4-(-3)
therefore, -2x and +2x is cut.
as a result -5y= -1
therefore y = 1 /5
then let us find x
2x + y = -3
::: 2x + 1/5= -3
therefore 2x= -3-1/5
finally, x= -16/5÷2
then x= 8/5
You need to divide this problem into two parts
first part is when it was accelerating.. that time use the equation of motion and calculate what is the total angle covered and hence you get the number of revolutions
then find the time of acceleration..so you ll understand for how much did you do the above calculation
for the rest of the time, the speed is constant (final angular speed).. so now you just use
w= theta/ time.. and get theta and again calculate the number of revolutions!
No it is not a perfect square
Answer:
The prefix dodeca- means 12. I hope this helped! :-)
