Answer:
7
Step-by-step explanation:
In general, the point of an inverse function is to show you the value that gives a particular function value. That is, ...

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>
Answer:
£17253.53 to the nearest hundredth.
Step-by-step explanation:
Decreasing by 9,5% is equivalent to multiplying by 1 - 0.095 = 0.905.
19064.67 * 0.905
= £17253.52635.
Answer:
Option C is the correct option.
Step-by-step explanation:
Considering the triangle ABC, the slope of the line CA is given by 
Again, considering the triangle CDE, the slope of the line EC is given by

Since CA and EC represents the same straight line so, we can write

Therefore, option C is the correct option. (Answer)
