A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit. The correct option is D.
What is a complex number?A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit, and satisfies the equation i² = -1; every complex number may be represented as a + bi, where a and b are real numbers.
To find the conjugate of a complex number, we change the sign of the complex part of the number. Therefore, the conjugate of -14-2i is -14+2i.
The modulus of the given complex number -14-2i is,
|z| = √[(-14)²+(-2)²]
= √(196 + 4)
= √200
= 10√2
Hence, the conjugate and modulus of –14 – 2i are -14+2i and 10√2, respectively.

A plane traveled 336 miles to Carson City and back. The trip there was with the wind. It took 4 hours. The trip back was into the wind. The trip back took 6 hours. What is the speed of the plane in still air? What is the speed of the wind?
Answer:
Thus, train speed = 70 mph while wind speed is. y = 14 mph
Step-by-step explanation:
Let x = speed of the plane in mph.
Let y = speed of wind in mph.
We are told that The trip there was with the wind. It took 4 hours. The trip back was into the wind. The trip back took 6 hours.
Formula for distance is;
Distance = speed × time
Thus;
(x + y)4 = 336
(x + y) = 84 - - - - (1)
Also;
(x - y)6 = 336
Divide both sides by 6
(x - y) = 56 - - - (eq 2)
Add eq 1 and 2 to give;
2x = 84 + 56
2x = 140
x = 140/2
x = 70 mph
Plug in 70 mAh for x in eq 1.
(70 - y) = 56
y = 70 - 56
y = 14 mph
Thus, train speed = 70 mAh while wind speed is. y = 14 mph

8. A tire dealer sells Supreme tires for $48 each and Prestige tires for $56 each. During one week, the sales for both tires totaled $2008. If 11 Prestige tires were sold, write and solve a linear equation to find the number of Supreme tires sold.
Answer:
31 Supreme tires were sold.
Step-by-step explanation:
Cost of one Supreme tire = $45
Cost of one Prestige tire = $56
Total sales = $2008
Let x represent quantity of supreme tyre
Let y represent quantity of Prestige tyre
So, the equation will be:
[tex]45x+56y=2008[/tex]
11 Prestige tires were sold, write and solve a linear equation to find the number of Supreme tires sold.
So, we are given y= 11 and we need to find value of x using above equation
[tex]45x+56y=2008\\45x+56(11)=2008\\45x+616=2008\\45x=2008-616\\45x=1392\\x=\frac{1392}{45}\\x=30.933\\ x\approx31[/tex]
So, 31 Supreme tires were sold.

a rectangle has a length of x3y4 inches and a width of xy7 inches . Which expression represents the ratio of the length of the rectangle to do width of the rectangle? (NEED HELP ASAP)
Answer:
A. x²/y³
Step-by-step explanation:
Given the following data;
Length = x³y⁴
Width = [tex] xy^{7}[/tex]
Ratio = length/width
[tex] Ratio = \frac{x^{3}y^{4}}{xy{^7}}[/tex]
Simplifying the equation by applying the law of indices (division), we have;
[tex]\frac{x^{3}}{x} = x^{3} - x^{1} = x^{3-1} = x^{2} [/tex]
[tex]\frac{y^{4}}{y^{7}} = y^{4} - y^{7} = y^{4-7} = y^{-3} [/tex]
Hence, rearranging the above values;
[tex] Ratio = \frac{x^{2}}{y^{3}}[/tex]
Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³.
