I think I could help you
Have fun and feel free to ask me something new.
Or we can prove some properities without calculating by details
The Greatest Common factor is 11x^2y so the factors are
11x^2y(x^2 - 2y)
C.
This is because the amount is more than what he needs to save, considering that he is probably has some money in his bank already.
We have to determine which value is equivalent to | f ( i ) | if the function is: f ( x ) = 1 - x. We know that for the complex number: z = a + b i , the absolute value is: | z | = sqrt( a^2 + b^2 ). In this case: | f ( i )| = | 1 - i |. So: a = 1, b = - 1. | f ( i ) | = sqrt ( 1^2 + ( - 1 )^2) = sqrt ( 1 + 1 ) = sqrt ( 2 ). Answer: <span>C. sqrt( 2 )</span>
