suter [353]3 years ago
8 0
The correct answer for this would be the second option. The equation that is used in the process in completing the square is this: <span>(x - 4)2 = 13.
The solution is this:
(x-4)(x-4) = 13
x^2 - 4x - 4x + 16 = 13
x^2 - 8x +16 = 13
x^2 - 8x = 13 -16
x^2 - 8x = -3
x^2 - 8x + 3 = 0
Hope this answers your question. Have a great day!</span>

If f(x) = 1 – x, which value is equivalent to |f(i)|?l
LenaWriter [7]

Answer:

Square root ( 2 )

Step-by-step explanation:

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: 1 inch = 20 feet

Step-by-step explanation: You can answer this question using Unit Rate. Khan Academy explains it better, but basically you take the ten inches and divide it by ten to get one. and to get the scale, you have to divide 200 by ten to get the unit rate where 1 inch equals 20 feet.
