B. (5 + 4i) (3 – 4i)
oc. (x + 2√2)
D. (x + 2/2i)(x – 2/2i)
Answers
The expression x²+8 is equivalent to ( x + 2√2i) ( x - 2√2i).The correct option is D.
What is an Expression?An expression is a statement consisting of variables, constants, and mathematical operators.
The expression x²+8 can be written as
( x )² - ( 2√2i)²
This is representing the binomial Identity
a² - b² = ( a+b) (a-b)
here a = x , b =2√2i
The expression can be written as
( x )² - ( 2√2i)² = ( x + 2√2i) ( x - 2√2i)
Therefore, The correct option is D.

Angle W measures 68 degrees more than angle F. Angles Wand
Fare supplementary. What is the measure of angle W?
Answers
Answer: The measure of angle W is 124°.
Step-by-step explanation:
Given: Angles W and F are supplementary.
We know that the sum of two supplementary angles is 180 degrees.
So, ∠W + ∠F = 180° (i)
As per given,
∠W = ∠F + 68° (ii)
Put value of ∠W from (ii) in (i)
∠F + 68°+∠F = 180°
⇒ 2 ∠F = 180°- 68°
⇒ 2 ∠F = 112°
⇒ ∠F = 56°
From (ii),
∠W = 56° + 68°
⇒ 124°
Hence, the measure of angle W is 124°.

Answers
Answer:
D
Step-by-step explanation:
So you are looking for the inverse equation. The original can be written as y=1/2x-6. For the inverse, your variables switch places. It's reflecting across the line y=x (that's what the inverse does). So you write it as x=1/2y-6. Now solve for the new equation:
Move 6 over: x+6=1/2y
Isolate y: 2(x+6)=y
This gets you D.

Any hypothesis that an analyst has accepted to be true and which forms the basis of an assessment is a: ______
Answers
Answer:
The correct answer is the alternate hypothesis.
Step-by-step explanation:
A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.
It is a hypothesis of no difference.
It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.
For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.
Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.
The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.
It is also known as the research hypothesis and is denoted by Hₐ.
Thus, the correct answer is the alternate hypothesis.

So, I am solving your concept based on an assumed graph which I have attached. It would anyways clear your concept.
Answer:
Please check the explanation!
Step-by-step explanation:
Given the attached graph below, it is clear that the right angle triangle ABC is shown.
Here are some of the information we can get from the right angle triangle ABC such as:
The angle at C = 30°side AB = 8 unitsWe have to determine the unknown side 'x' using the trigonometric ratios
As
tan Ф = opp/adjacent
From the diagram it is clear that
Ф = 30°
opp=8
adjacent = BC = x
so
tan Ф = opp/adjacent
tan 30 = 8/x
1/√3 = 8/x
x = 8×√3
x = 13.9
Therefore, the missing length will be: x = 13.9

An electronics store has a current inventory of 50 stereo systems. The lowest priced stereo system in the store sells for $800, The lowest priced stereo system in the store sells for 800 dollars, and the highest priced stereo system sells for $3000. and the highest priced stereo system sells for 3000 dollars. Which of the following is the maximum amount of $3000 systems on hand Which of the following is the maximum amount of 3000 dollar systems on hand if the current inventory totals $111,000?
The answer is 32, I need an explanation how to find the answer.
Answers
Explanation:
let H = number of expensive high price stereo
systems
let L = number of less expensive low price
stereo systems
H +L = 50 =
3,000H + 80OL = 110,000
H = 50 - L (now replace)
3,000 (50 - L) + 800 L = 110,00
150,000 - 3,000L + 800L = 110,000
150,000 - 110,000 = 3,000L - 800L =
40,000 = 2,2OOL
L = 40,000 / 2,200 = 18.18 = 18 lower priced = =
stereo systems H = 50 - 18 = 32 higher priced stereo systems
=
=
(3,000 x 32) + (800 x 18) = 96,000 + 14,400 = 110,400
Even though the answer is not exact, if you had 33 high cost stereo systems, your inventory's cost = $112,600 which is $1,600 off

Answer:
[tex]3\sqrt{2}[/tex]
Step-by-step explanation:
The Magnitude of a Complex Number
A complex number is expressed in rectangular form as:
[tex]Z=a+ b\mathbf{ i}[/tex]
The absolute value or magnitude of Z is calculated as follows:
[tex]\mid Z\mid=\sqrt{a^2+b^2}[/tex]
We are given the number
[tex]Z=-4-\sqrt{2}\mathbf{ i}[/tex]
Here: a= -4, b=[tex]-\sqrt{2}[/tex]
Calculating the absolute value:
[tex]\mid Z\mid=\sqrt{(-4)^2+(-\sqrt{2})^2}[/tex]
Operating:
[tex]\mid Z\mid=\sqrt{16+2}=\sqrt{18}[/tex]
Factoring 18:
[tex]\mid Z\mid=\sqrt{3^2*2}[/tex]
Taking the square root of 3^2:
[tex]\mid Z\mid=3\sqrt{2}[/tex]
