Answer:
0.122
Step-by-step explanation:
9882/81 = 122
122/1000 = 0.122
For x +iy absolute value = √(x² + y²)
Absolute value of -4-√2i = -4-i√2, comparing x = -4, y= -√2
<span>
Absolute value = </span>√( (-4)² + (-√2)²),
(-4)² = (-4)*(-4) = 16, (-√2)² = -√2 * -√2 = 2
<span>
= </span><span>√( (-4)² + (-√2)²)
</span><span>
</span>= √(16 + 4) = √20
√20 = √(4*5) = √4 * √5 = 2√5
Absolute value = <span>2√5</span>
Answer: 1, 3, both show a change in temp
