Answer:
2√37
Step-by-step explanation:
Given some complex number z, |z| is what's called <em>magnitude </em>of a complex number -- its distance from 0. Unlike the more straightforward process of finding the absolute value of a real number (a number on the number line) complex numbers are <em>two-dimensional</em>, and so to talk about their magnitude, we need to bring in the Pythagorean theorem.
The real and imaginary part of the complex number 12 - 2i represent the point (12, -2) on the complex plane. Drawing lines perpendicular to the real and imaginary axes and joining them with a line from the origin to the point gives us a right triangle with legs 12 and 2. Using the Pythagorean theorem, the hypotenuse, |12 - 2i|, must be equal to . We can pull a 4 out of the 148 to give us
Answer:
2
Step-by-step explanation:
<em>"How many ways can we choose a Senator from a chosen state?"</em>
Each state has 2 Senators. So there are 2 ways we can choose a Senator from any selected state.
<em>"How many ways can we choose 3 states to be represented?"</em>
The order in which the states are selected isn't important, so the number of ways 3 states can be selected is:
₅₀C₃ = 19,600
<em>"How many ways can the 3-Senator committee be formed such that no 2 Senators are from the same state?"</em>
The number of ways a committee can be formed is:
2×2×2×19,600 = 156,800
