Answer:

Step-by-step explanation:

The magnitude of the complex number is expressed as;

|z| = √x²+y²

Given the complex number z = 4i+3j, x = 4 and y = 3

Substitute

|z| = √x²+y²

|z| = √3²+4²

|z| = √9+16

|z| = √25

|z| =5

Hence the magnitude is 5

The equation that could be used to determine x is ([tex]x^{2}[/tex] + 8x - 308).

As per the question, the small integer is x. So, the large integer will be (x + 8).

Also, the question mentions that their product is 308. Representing the given information in mathematical equation form -

x (x + 8) = 308

Performing multiplication on Left Hand Side of the equation

x² + 8x = 308

Shifting 308 from Right Hand Side to the Left Hand Side of the equation. the equation that will form is -

x² + 8x – 308 = 0

On solving this quadratic equation, we will get the negative numbers, which will validate our formed equation.  

x² + 8x – 308 = 0

x² + 22x - 14x – 308 = 0

x (x + 22) - 14 (x + 22) = 0

(x + 22) (x - 14) = 0

x = -22 and 14

Since the numbers are negative, hence, value of small number is -22.

Large number = -22 + 8

Large number = -14

Thus, the small and large number is -22 and -14.

Therefore, the correct equation is x² + 8x – 308 = 0.

Two negative integers are 8 units apart on the number line and have a product of 308. Which equation could be used to determine x, the smaller negative integer? x² + 8x – 308 = 0 x²  – 8x + 308 = 0 x²  + 8x + 308 = 0 x²  − 8x − 308 = 0

Answer:

x = 3

4^2 + x^2 = 5^2

solve for x

16 + x^2 = 25

x^2 = 25-16

x^2 = 9

sqrt of x^2 = 3

Answer: Willis will take 3 hours to paint the room by himself.

Step-by-step explanation:

Given: Time taken by James to complete job by himself = 6 hours

Let Time taken by Willis to complete job by himself = t hours

Together they take 2 hours.

[tex]\dfrac{1}{6}+\dfrac{1}{t}=\dfrac{1}{2}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{2}-\dfrac{1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{3-1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{2}{6}\\\\\Rightarrow\ t=\dfrac{6}{2}\\\\\Rightarrow\ t=3[/tex]

So,  Willis will take 3 hours to paint the room by himself.

Answer:

$21.78

Step-by-step explanation:

We know that each pack of milk costs $3.96, so if we buy 5.5 of these, we will have to pay $3.96 5.5 times. In other words, we must multiply 3.96 by 5.5:

3.96 * 5.5 = 21.78

Thus, Mandy spends $21.78 in all.

Answer:

a = 9r²

Step-by-step explanation:

Given

r = [tex]\frac{\sqrt{a} }{3}[/tex] ( multiply both sides by 3 to clear the fraction

3r = [tex]\sqrt{a}[/tex] ( square both sides )

(3r)² = ([tex]\sqrt{a}[/tex] )²

not sure what your question is but if youre trying to solve for the system of equations your awnser is (5,3/2)

Answer:

x= 5, y= 3/2

Step-by-step explanation:

5x -4y =19 (Equation 1)

x+ 2y=18 (Equation 2)

Using substitution method,

From equation(2),make x the subject of formula

x= 8-2y (Equation 3)

Substitute equation 3 into equation 1

5x -4y= 19

5(8-2y) -4y = 19

40 -10y -4y = 19

40-14y=19

Collect like terms

40-19=14y

21=14y

y= 21/14 = 3/2

Substitute for y in equation 3

x= 8 -2y

   8- 2(3/2)

  =8 -3

x = 5

Answer:

If there are no restrictions, the domain is all real numbers.

- infinity < x < infinity

Answer:

Step-by-step explanation:

Functions are a correspondence between two sets, called the domain and the range. When defining a function, you usually state what kind of numbers the domain (x) and range (f(x)) values can be. But even if you say they are real numbers, that doesn’t mean that all real numbers can be used for x. It also doesn’t mean that all real numbers can be function values, f(x). There may be restrictions on the domain and range. The restrictions partly depend on the type of function.

In this topic, all functions will be restricted to real number values. That is, only real numbers can be used in the domain, and only real numbers can be in the range.
