this is the ans.
Answer:
None of the option
Step-by-step explanation:
Given :
(7-3i)+[tex](x-2i)^{2} -(4i^{2} +x^{2} )[/tex]
(7-3i)+([tex]x^{2}[/tex]+4[tex]i^{2}[/tex]-4xi)-(-4+[tex]x^{2}[/tex]) Since, [tex]i^{2} =-1[/tex]
(7-3i)+[tex]x^{2}[/tex]-4-4xi +4-[tex]x^{2}[/tex]
7-3i-4xi
7-i(3+4x)
Therefore, None of the option is correct.

What relationship do you notice between the total number of fish each has caught after each hour?
Answers
Answer:
Scott always has 2 more fish per hour or S=M+2
Step-by-step explanation:
5-3 = 2, 9-7 = 2,...
For any given hour, Scott has reeled in 2 more fish compared to Megan.
We can see this by subtracting Scott's amount and Megan's amount for any row.
Row One: 5-3 = 2Row Two: 9-7 = 2Row Three: 13-11 = 2Row Four: 17-15 = 2Because any given row has the same difference, this tells us that the slopes of each are the same.
The equation for Megan is y = 4x-1 while Scott's equation is y = 4x+1
x = number of hours, y = number of fish caught
Lines with equal slopes indicate parallel lines. If these trends keep up, then Megan will never catch Scott (she'll always be 2 fish behind him).

Option C is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
To complete the square, we add and subtract the square of half of the coefficient of x, i.e., (10/2)² = 25, inside the parentheses:
8(x²+ 10x + 25 - 25) = -5
Simplifying the expression inside the parentheses.
8(x + 5)² = 200
Dividing both sides by 8.
(x + 5)² = 25
Taking the square root of both sides.
x + 5 = ±5
Solving for x.
x = -10 or x = 0
Thus,
The missing number is 25.

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB=20 and AD=10, what is the length of AC?
Answers
Answer:
mAC = 40
Step-by-step explanation:
Use similar triangles,
BAC and DAB are similar
therefore
CA/AB = BA/AD
CA/20 = 20/10
cross multiply
AC = CA = 20*20/10 = 40
Or use metric relations
CA*AD = BA^2
CA = BA^2/AD = 20^2/10 = 40

73,205 vinyls
Step-by-step explanation:
To calculate the number of vinyls sold we need to calculate the compounded increase. To do this we simply raise the number of times that the initial value increases by the number of difference in years from the start to the current year. Then we multiply this number by the initial number of vinyl records. Since there are 4 years between 2012 and 2016, the formula would be the following...
50,000 * [tex]1.1^{4}[/tex] = x
50,000 * 1.4641 = x
73,205 = x
Finally, we can see that there will be a total of 73,205 vinyls in 2016

7 7/8 is my answer
Step-by-step explanation:
All you need to do is turn you mixed numbers into improper fractions 4 1/2 as an improper fraction is 9/2 and 1 3/4 as an improper fraction is 7/4. Then, you would mulitply them which will give you 63/8. After that, you would divide 63 by 8 which is 7 is you is your answer but you also have 7 as a remainder, which is good. That would be your numerator and the other 7 would be your mixed number. The 8 we were just talking about, would stay as your numerator. So, your answer is 7 7/8.

Your company is considering offering 600 employees the opportunity to transfer to its new headquarters in Ottawa and, as personnel manager, you decide that it would be fairest if the transfer offers are decided by means of a lottery. Assuming that your company currently employs 200 managers, 300 factory workers, and 900 miscellaneous staff, find the following probabilities, leaving the answers as formulas.
(a) All the managers will be offered the opportunity.
C(___,___)
C(___,___)
(b) You will be offered the opportunity.
C(___,___)
C(___,___)
Answers
Answer:
Probability of 100 managers being selected= 100C100*1100C800/1200C900
Probability of selecting just one manager = 1C100*1199C899/1200C900
Explanation:
Given 100 managers, 200 factory workers, 900 miscellaneous workers, and workers bring transferred 900
To find probability of 100 managers leaving given that probability = number of favorable outcomes/total number of outcomes
We use combination since order doesn't matter:
Combination formula= n!/r!(n-r)! Where n= total number of outcomes and r is number of outcome at one time and ! is factorial
Probability of 100 managers using nCr formula for each item = 100C100*1100C800/1200C900
Probability of 1 manager also applying nCr formula as above =1C100*1199C899/1200C900
The probability is the ratio of the favorable event to the total number of events. The probabilities are as follows;
a. P = ¹⁰⁰C₁₀₀ × ¹¹⁰⁰C₈₀₀ / ¹²⁰⁰C₉₀₀
b. P = ¹⁰⁰C₁ × ¹¹⁹⁹C₈₉₉ / ¹²⁰⁰C₉₀₀
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

using the image,find angle x and y
Answers
Answer:
x =55 degrees
y = 35 degrees
Step-by-step explanation:
We know that the distance from the center of the circle to the circumference is the radius
that means the triangle starting out from O is isosceles since two of the sides are radii and thus the angle of those sides are the same
Let us call one of the angles z
we know that the sum of the angles in a triangle is 180 degrees
That simply means;
80 + 2z = 180
2z = 180-80
2z = 100
z = 100/2
z = 50 degrees
So the angles at each upper end of the cyclic quadrilateral are;
x + 50 and y + 50
we know that the angles that face each other in a cyclic quadrilateral are supplementary
Thus;
95 + y+ 50 = 180
y= 180-95-50
y= 180-145
y = 35 degrees
Now, for x, the angle supplementary to the angle that faces x+ 50 equals x + 50
Thus;
x + 50 = 105
x= 105-50
x = 55 degrees
