We get to the conclusion that the response is 10x after examining the two sides.

The above equation's roots are 5 + 3i and 5 - 3i.

This indicates that x - (5+3i) and x - are the two factors of the provided polynomial (5 - 3i). The original statement must be the sum of the elements. We can thus write:

x² - (answer) + 34 = (x - 5 -3i)(x - 5 + 3i).........(1)

Simplifying the right hand side:

[tex]& (x-5-3 i)(x-5+3 i) \\[/tex]

[tex]& =x^2-5 x+3 x i-5 x+25-15 i-3 x i+15 i-9 i^2 \\[/tex]

The mSBY is the measure of the interior angle formed when three lines meet at a point. In this case, the three lines are a regular pentagon, a regular octagon, and SBY.

To calculate the mSBY, we must first calculate the measure of each of the other two angles. A regular pentagon has five sides, and each angle measures 108°. A regular octagon has eight sides, and each angle measures 135°. To calculate the mSBY, we must use the formula mSBY = 180° - (mP + mO). Using this formula, we can calculate that the mSBY is 37°: 180° - (108° + 135°) = 37°.

To visualize this, imagine three lines coming together at a point, forming an interior angle. The measure of the interior angle is the mSBY. The measure of the regular pentagon angle is 108°, and the measure of the regular octagon angle is 135°. When these two angles are added together, they equal 243°. Since the sum of the interior angles of a triangle is 180°, the measure of the interior angle must be 180° - 243°, which is 37°.

Since, the formula for variance is Variance = (σ)², where σ denotes standard deviation, the statement "the standard deviation is the positive square root of the variance" is false.

What is standard deviation?

The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability.

The dispersion of the set of data values is measured by the standard deviation. The sigma symbol (σ) serves as its symbol.

This indicates that the data values tend to be more dispersed over a greater range for a higher standard deviation. While a lower number of standard deviation results from data being closer to its mean.

Variance, which is the expectation of the squared standard deviation, is a measure of how widely distributed the data are with respect to their mean.

As a result, the relationship between standard deviation and variance can be expressed numerically as, Variance = (σ)².

Therefore, standard deviation is not square root of variance.

When two linear equations in two variables have no solution, it means that the equations are not compatible. This means that the equations cannot be solved simultaneously, as there is no set of values that can satisfy both equations. This can be seen by graphing the equations on a coordinate plane. If the two lines are parallel, then they will never intersect, and thus, there is no solution. If the two lines are the same line, then they will intersect at every point, and thus, any point on the line is a solution.

In the case of two linear equations in two variables, if the equations are not parallel and not the same line, then the equations will intersect at one point. This point is the solution to the two equations. If the equations are not parallel and not the same line, but do not intersect, then there is no solution. This means that the equations are incompatible and cannot be solved simultaneously.

What is an orthogonal vector?

An orthogonal vector is a vector that is perpendicular to another vector in a given space. In other words, two vectors are orthogonal if their dot product is equal to zero.

To find a vector orthogonal to both 2, 2, 0 and 0, 2, 5 of the form 1, we can take the cross product of the two vectors, which results in a vector that is orthogonal to both. The cross product of 2, 2, 0 and 0, 2, 5 is given by:

(2, 2, 0) x (0, 2, 5) = (20, -10, -4)

So, a vector orthogonal to both 2, 2, 0 and 0, 2, 5 is given by (20, -10, -4). We can normalize this vector by dividing it by its magnitude, which is equal to sqrt(20^2 + (-10)^2 + (-4)^2) = sqrt(444). The normalized vector will be of the form 1:

Answer: 1 7/10

Step-by-step explanation:

The range of possible values for the third side of the triangle is d)6 < x < 26.

The third side of an acute triangle must be shorter than the sum of the other two sides and longer than the difference between the other two sides. By using the Pythagorean Theorem, we can find the range of possible values for the third side.

The Pythagorean Theorem states that the sum of the squares of the two sides of a right triangle equals the square of the hypotenuse. So, for this triangle, we have 10^2 + 16^2 = x^2.

Solve for x: x^2 = 256, so x = √256 = 16.

The third side must be shorter than the sum of the other two sides. So, the maximum value for x is 16 + 10 = 26.

The third side must be longer than the difference of the other two sides. So, the minimum value for x is 16 - 10 = 6.

Therefore, the range of possible values for the third side of the triangle is 6 < x < 26.

"Owning a home provides a partial tax shelter for housing-related expenses" the following is an advantage of purchasing and owning a home.

Hence, option (B) is correct choice.

The Benefits of Owning a Home:

Interest rates are low.

Creating equity: The difference between what you can sell the house for and what you owe is your equity. As you pay down your mortgage, your equity rises. Over time, more of your monthly payments will be applied to the loan balance rather than the interest, resulting in more equity.

Federal tax breaks: Mortgage interest is deductible on the first $750,000 of the house's purchase price, as are home equity loan interest, property taxes up to $10,000 if married ($5,000 if married filing separately), and various closing fees at the time of purchase.

Greater privacy: Because you own the property, you may renovate it to your desire, something tenants do not have.

Home office: The work-at-home craze may persist after the epidemic has passed, implying that more of us will require a home office. The appropriate configuration affects both comfort and productivity.

Monthly payments that are predictable: A fixed-rate mortgage requires you to pay the same amount each month for principle and interest until the loan is paid off. Rents are subject to rise with each annual lease renewal. Changes in property taxes or homeowner's insurance can affect monthly payments, although not as often as rent hikes.

Stability: People tend to stay in a house they own for a longer period of time, if only because purchasing, selling, and relocating is difficult.

Due to the triangle being translated 1 unit down and 3 units to the right, the new x-coordinate of R is now -2+3 = 1.R's x-coordinate was 2, thus 2 Plus 3 equals 1.

Triangle PQR is formed by points P (2, 1), R (2, 5) and Q (6, 5) and is then translated 1 unit downward and 3 units to the right. This indicates that all three points move three units to the right and one unit down. We may utilise R's initial x-coordinate, which was -2, to determine its new x-coordinate. Then, as R is being translated three units to the right, we add three to it. Consequently, R's new x-coordinate is now -2 + 3 = 1. Triangle PQR has been translated one unit down and three units to the right, giving rise to a new x-coordinate of R of 1.

N = log((100,000 / 1500) + 1) / log(1 + 0.011)

N = log(66.67) / log(1.011)

N = 4.67 quarters

In conclusion, It will take Naomi approximately 4 quarters and 8 months, or 4.67 quarters to reach her goal.

The probability that the system works under these conditions is 0.81 (0.90 x 0.90 = 0.81).

This question uses the concept of independent probabilities, Independent probabilities refer to the likelihood of two or more events occurring independently of each other.

In other words, the probability of one event occurring does not influence the probability of another event occurring.

This means that if the probability of one event occurring is known, the probability of the other event occurring can be calculated independently.

given below

Step 1: Determine the probability that both components A and B will work.

Step 2: Multiply the probability that component A will work by the probability that component B will work.

Step 3: The result of Step 2 is the probability that the system will work under these conditions.

a. independent event  P(AuB)=P(A)+P(B) b. mutually exclusive event  P(AuB) = P(A) + P(B) - P(AnB) c.  independent event P(A and B) = P(A).P(B)

d.   complement P(A') = 1 - P(A)

a. For two events A and B the union of the two sets is  simply all the elements present in both set. This can be expressed as

P(AuB)=P(A)+P(B)

b. Two events are said to be mutually exclusive if they cannot occur at the same time. i.e no same element must be present in both events at a time. This can be expressed as

P(AuB) = P(A) + P(B) - P(AnB)

c.  event A and event B are said to be independent if the incidence of event A  does not affect the probability of the event B.

This can be expressed as

P(A and B) = P(A).P(B)

d. complement of an event are simply all the occurrence not in he set but in the universal set.

the complement of set A can be expressed as

P(A') = 1 - P(A)
