The polynomial w^2+18w+84 cannot be factored

The perfect square trinomial is w^2+18w + 81

----------

The reason the original can't be factored is that solving w^2+18w+84=0 leads to no real solutions. Use the quadratic formula to see this. The graph of y = x^2+18x+84 shows there are no x intercepts. A solution and an x intercept are basically the same. The x intercept visually represents the solution.

w^2+18w+81 factors to (w+9)^2 which is the same as (w+9)(w+9). We can note that w^2+18w+81 is in the form a^2+2ab+b^2 with a = w and b = 9

================================================

b.

The polynomial y^2-10y+23 cannot be factored

The perfect square trinomial is y^2-10y + 25

---------

Using the quadratic formula, y^2-10y+23 = 0 has no rational solutions. The two irrational solutions mean that we can't factor over the rationals. Put another way, there are no two whole numbers such that they multiply to 23 and add to -10 at the same time.

If we want to complete the square for y^2-10y, we take half of the -10 to get -5, then square this to get 25. Therefore, y^2-10y+25 is a perfect square and it factors to (y-5)^2 or (y-5)(y-5)

Preventing identity theft involves securing personal items like credit cards and wallets, using strong passwords, monitoring credit history, and being cautious when sharing personal information, especially during job searches or online interactions.

Best Practices to Prevent Identity Theft

Identity theft, or 'True-name Fraud,' is a significant threat where criminals use stolen personal information to commit fraud. Protecting oneself from identity theft involves a number of crucial steps:

Answer:

x = 8

y = 146

Error = 4.86%

Step-by-step explanation:

Number of business class passenger = x

and the economy class passenger = y

Total number of passengers = 154

x + y = 154 ------(1)

Cost of business class tickets and economy class tickets are €320 and €85 respectively.

Total amount received by airlines is €14970.

320x + 85y = 14970

64x + 17y = 2994 --------(2)

Multiply equation (1) by 17 and subtract from equation (2)

(64x + 17y) - (17x + 17y) = 2994 - 2618

47x = 376

x = 8

From equation (1),

8 + y = 154

y = 154 - 8

y = 146

Airline officer wrote down the amount received as €14270

Then difference from the actual amount received = 14970 - 14270

                                                                                   = €700

% Error =  [tex]\frac{\text{Difference in amount}}{\text{Actual amount}}\times 100[/tex]

            = [tex]\frac{700}{14970}\times 100[/tex]

            = 4.676

            ≈ 4.68%

Therefore, x = 8 and y = 146

             and % error = 4.68%

Answer:

The last one

Step-by-step explanation:

The first one would be multiplication because you want to find the total thickness, the second one is division because it gives the total value and the amount of bags, the third one is addition because it gives you a starting value and says that they work this amount more in this month, and the last one is subtraction because he first pays with a gift card, and then with cash.

The situation that can be represented by the equation 15 - x = 63.75​ is (d)

The equation is given as:

15 + x = 63.75

The above equation is a addition equation.

This means that the situation or scenario that describes the situation must illustrate addition.

From the list of given option, the option (d) perfectly describes the scenario.

This is so because 15 represents the worth of gift card, 63.75 represents the total amount and x represents the amount spent in cash

D

Step-by-step explanation:

On the graph, the first action you see is a straight line going up. The key word you look for in the word explanations are "increase" and "constant rate". Then, the 2nd action you see is a straight line not going up or down, just staying on the same level. This could be called "remaining the same" or stopping/resting. Then, you see a straight line going down. You look for "decrease" at a "constant rate." D matches all of those.

Answer:

x = 2   days

y = 250  $

Step-by-step explanation:

We call "y"  total renting costs  and  "x" total vacation days

according to that in first case we have:

y  =  100*x  + 50

And for the second case

y  =  120*x +  10               (1)

That two equation system represent the equation system of the situation, therefore if we solve that system we will determine the choises with same costs

equating these two equations:

100*x  +  50  =  120*x + 10

50 - 10  = 120*x - 100*x

20*x = 40

x = 2   days

Plugging that value in any of the equation (1) or (2) we get y value

y  =  120*2  +  10

y = 250  $

Answer: The teacher's age increases the mean.

Step-by-step explanation:

14.2 + 27 = 41.2 years

41.2/2 = 20.6 years

20.6 years > 14.2 years

Adding the 27-year-old teacher to the student book club, which has a current mean age of 14.2 years, will increase the mean age of the club.

When a 27-year-old teacher is invited to join the book club with an average age of 14.2 years, the teacher's age will increase the mean (average) age of the club members. This occurs because the mean age is calculated by adding all of the ages together and dividing by the total number of individuals in the group. Adding a number that is significantly higher than the current mean will raise the overall total, which, when divided by the new total number of individuals, will result in a higher average age than 14.2 years. We do not have the exact number of original club members, so we cannot calculate the new mean exactly, but we can confidently say the mean age will increase due to the addition of the 27-year-old teacher's age.

If [tex]\(y = \log_b(x)\)[/tex], then [tex]\(b^y = x\)[/tex] is the equivalent exponential form.

The logarithmic equation [tex]\(y = \log_b(x)\)[/tex] is equivalent to the exponential form [tex]\(b^y = x\)[/tex]. These two forms are related by the definition of logarithms.

In the logarithmic form [tex]\(y = \log_b(x)\)[/tex], [tex]\(b\)[/tex] is the base of the logarithm, [tex]\(x\)[/tex] is the argument of the logarithm, and [tex]\(y\)[/tex] is the exponent to which the base [tex]\(b\)[/tex] must be raised to obtain [tex]\(x\)[/tex].

In the exponential form [tex]\(b^y = x\)[/tex], [tex]\(b\)[/tex] is the base, [tex]\(y\)[/tex] is the exponent, and [tex]\(x\)[/tex] is the result of raising the base [tex]\(b\)[/tex] to the power of [tex]\(y\)[/tex].

So, if [tex]\(y = \log_b(x)\)[/tex], then [tex]\(b^y = x\)[/tex] is the equivalent exponential form.

The probable question may be:

"What is the exponential form equivalent to the logarithmic equation [tex]\(y = \log_b(x)\)[/tex], where [tex]\(b\)[/tex] is the base of the logarithm, [tex]\(x\)[/tex] is the argument, and [tex]\(y\)[/tex] is the exponent? Provide the expression in the form [tex]\(b^y = x\)[/tex]."

The equation [tex]\(y = \log_b^x\)[/tex] can be represented in exponential form as [tex]\(b^y = x\).[/tex]

When dealing with logarithms and exponential functions, there exists an inverse relationship between them. The logarithm is the inverse of the exponential function, and vice versa. In the given equation [tex]\(y = \log_b^x\),[/tex] the logarithm is in base \(b\) with an exponent of \(x\). To rewrite this equation in exponential form, we need to switch from logarithmic notation to exponential notation.

In exponential form, the base[tex](\(b\))[/tex]is raised to the power of the logarithm ((y)), resulting in [tex]\(b^y\).[/tex] The result of this exponential expression is the value (x\), which is the argument of the logarithm. This transformation showcases the fundamental relationship between logarithms and exponentials, demonstrating that they are different representations of the same mathematical concept.

Expressing the equation as[tex]\(b^y = x\)[/tex]in exponential form clarifies how the logarithmic statement[tex](\(y = \log_b^x\))[/tex] translates into an equivalent exponential form. It emphasizes the reciprocal relationship between logarithms and exponentials, providing a clear understanding of how these forms interrelate in mathematics.

This transformation from logarithmic to exponential form serves to simplify expressions, solve equations, and understand the fundamental connection between logarithms and exponentials in mathematical operations.
