We are basically asked to perform the product of expressions that contain complex numbers a s roots of polynomials. So it is essential to identify the complex root in order to facilitate our products that otherwise could be really time consuming.
First product:
(x + 3 + 5i) (x + 3 - 5i) we are going to write as: ((x +3) +5i) ((x+3) - 5i). So this is going to be interpreted as a difference of squares (a + b) ( a - b) = a^2 - b^2:
((x +3) +5i) ((x+3) - 5i) = (x+3)^2 - (5i)^2 = (x+3)^2 - (-25) = (x+3)^2 + 25
We are using the fact that (i)^2 = -1 to convert - 25 (i)^2 = + 25
Now we solve the square of the binomial (x+3) , that is:
(x+ 3)^2 = x^2 + 6x + 9
Now this combined with + 25 gives: x^2 + 6x + 34 This is one of the options in blue background shown at the tops (the fourth one starting from the left)
Second product:
(x - 4i) (x + 4i) which is an easirer product than the one above because we can solve it just using difference of squares: (a - b) (a + b) = a^2 - b^2:
(x - 4i) (x + 4i) = x^2 - (4i)^2 = x^2 - 16 (i)^2 = x^2 +16
This is the second expression in blue background from left to right.
Third product:
(x - 6 + i) (x - 6 - i) for which we apply the same technique as in the first product we solve above:
(x - 6 + i) (x - 6 - i) = ((x - 6) + i) ((x - 6) - i) = (x-6)^2 - (i)^2 = (x-6)^2 - (-1) = (x-6)^2 + 1 = x^2 - 12 x + 36 + 1 = x^2 - 12 x + 37 which is the very first expression in blue background in the image you uploaded.

Let f be the function given by f(x)=∣∣x2−2∣∣(x+0.4)(x2−2)(x+0.4). On which of the following open intervals is f continuous?
Answers
Using the continuity concept, it is found that the function is continuous on the following interval:
C. (0, 1).
What is the continuity concept?A function f(x) is continuous at x = a if it is defined at x = a, and the lateral limits are equal, that is:
[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]
In the context of this problem, the numeric values are especially relevant, as the function not continuous at the zeros of the denominator.
The denominator of the function is given as follows:
(x² - 2)(x + 0.4).
Hence the discontinuity points are:
x² - 2 = 0 -> x = -1.41 and x = 1.41.x + 0.4 = 0 -> x = -0.4.Hence the only interval in which the function is continuous over the entire interval is given by option C.

The equation is y=5x+16.
How to form the required equation?The formula y=mx+b is expressed in slope-intercept form. We are aware of the slope (m) as well as a point (-2,6). We now require the y-intercept (b).We need to enter the information we are aware of in order to solve the y-intercept (b).Y = 6, M = 5, and X = -2 are known values. The equation must be like this: 6=5(-2)+bContinuing, 5(-2) is just 5 times -2, or -10. The new formula is 6=-10+b.Since we must repeat this process for both sides, we must add 10 to the right side to cancel it out and 10 to the left to obtain b. 6+10=-10+10+bB must therefore be 16 because of this.The last step is to construct the equation, where all that is required is to correct the values of m and b in the slope-intercept equation y=mx+b. We know that m is 5 and b is 16.y - 6 = 5(x - (-2)) y=5x+16Therefore, y=5x+16 is the solution.To learn more about equations, refer

At mid-semester Savannah scored 118 out of 150 points on quizzes, 73, 89, and 97 on the first three exams,each worth 100 points. She got extra credit on her project with a score of 28 out of 25 possible points, and she had perfect attendance to class. Compute Savannah's grade percentage in the class so far.
Answers
Savannah's grade percentage in the class so far is 92.28%.
What is the grade percentage?
Percentage is a measure of frequency that is used in mathematics. The sign that represents percentage is %. In order to convert a number to percentage, multiply the fraction of that amount by 100 or by the given percentage.
Savannah's grade percentage can be determined by adding her percentage score in each component that makes up the total grade.
Percentage score in quizzes = (score obtained / maximum score) x percentage allocated to quizzes
(118 / 150) x 15% = 11.80%
Percentage score in the three exams = (average of the three scores / maximum score) / percentage allocated to exams
Average of the three scores = (73+ 89 + 97) / 3 = 86.33
(86.33 / 100) x 55% = 47.48%
Percentage score in the project = (score in the project / maximum points) x percentage allocated to project
(28 / 25) x 25% = 28%
Percentage score in attendance = 5%
Total grade percentage so far: 5% + 28% + 47.48% + 11.80% = 92.28%

How can the standard error mean be obtained?The formula N provides the standard error mean. We must be aware that the standard error means in the given question is denoted by the letter M.
Applying the formula now, we get the following:
σM = 64/√64
64 divided by its square root gives us the number 8.
The standard error means is thus equal to 64 divided by 8, or 8.

) Let us assume that the interest was compounded annually. The formula for calculating compound interest is expressed as
A = P(1 + r/n)^nt
where
A is the amount after t years
P is the principal or initial amount invested
r is the interest rate
n is the number of compounding periods in a year
t is the number of years
From the information given,
P = 130
r = 4% = 4/100 = 0.04
n = 1 because it was compounded once in a year
t = 10
By substituting the values into the formula, we have
A = 130(1 + 0.04/1)^1 * 10
A = 130(1.04)^10
A = 192.43

Let the number of people be x and the total charges be y
So, we have
y = 20x
The above equation is a linear function
The domain and the rangeFrom the question, we have
Total number of people per seat = 5
So, the domain is 0 <= x <= 5
