Answer:
y = √{(a - x)/2b}
Step-by-step explanation:
x=a-2by²
2by² = a - x
divide through by 2b
y² = (a - x)/2b
y = √{(a - x)/2b}
I don’t really understand for question 11 to 13
An 180-degreee rotation would return the square to its original position.
Take 3/7 and multiply it by 2 to find out how much she knits in one hour. Then take that value and multiply by 12 to find out how much she knits in 12 hours.
3/7 x 2 = 6/7
6/7 x 12 = 72/7 or 10 2/7.
Answer:
The imaginary part is: z = 19
Step-by-step explanation:
For real numbers a and b, a number written in form a+bi is called a acomplex number. The value a is called the real part and b is called the imaginary part of complex number.
