The <u>absolute value</u> of the <u>complex number</u> z=a+bi is |z|=\sqrt{a^2+b^2}.

Consider the complex number z=-4-\sqrt{2}i. For this complex number a=-4 and b=-\sqrt{2}.

Therefore, the absolute value of this complex number is

|z|=\sqrt{(-4)^2+(-\sqrt{2})^2}=\sqrt{16+2}=\sqrt{18}=3\sqrt{2}.

Answer: correct choice is B

You can use the expression 2e+2w to find the perimeter of a rectangle where e is the length and w is the width. Interpret the co
In-s [12.5K]

Answer: The coefficient of terms is 2 represents length of 2 equal and opposite sides of rectangle.

Step-by-step explanation:

A rectangle is a 4 sides closed quadrilateral where opposite sides are equal .

So , length of one pair of opposite is represented by 'l'  [l= length]

Such that sum of these two sides = l+l=2l

The other pair of opposite sides s represented by 'w'  [w= width]

Such that sum of these two sides = w+w=2w

Perimeter is the sum of sides.

So, perimeter of rectangle = 2l+2w.

The coefficient of terms is 2 represents length of 2 equal and opposite sides of rectangle.

The figure below shows segments KL and MN which intersect at point P. Segment KM is parallel to segment LN:
DerKrebs [107]

Answer:

Angle KMP is congruent to angle LNP because they are alternate interior angles.

Step-by-step explanation:

Alternate interior angles are angles inside the parallel lines and on opposite sides of the transversal.

KM and NL are parallel to one another.  KMP and LNP both fall between the parallel lines; this makes them interior.

KL is a transversal for the two parallel lines.  KMP and LNP are on opposite sides of the transversal; this makes them alternate.

Therefore they are alternate interior angles.
