The logarithmic eqaution log₂ 4 + log₂ (c-9) = 5 has its solution to be 17

From the question, we have the following parameters that can be used in our computation:

log₂ 4 + log₂ (c-9) = 5

Apply the product rule of logarithm

So, we have

log₂(4 * (c-9)) = 5

This can then be expressed as

(4 * (c-9)) = 2⁵

Divide both sides by 4

c - 9 = 2³

So, we have

c - 9 = 8

When evaluated, we have

c = 17

Answer:

(x, y) = (4, 3)

Step-by-step explanation:

y = x - 1 (Equation 1)

2x - 3y = -1 (Equation 2)

We can use substitution method:

Substitute the expression for y from Equation 1 into Equation 2 and solve for x:

2x - 3(x - 1) = -1

2x - 3x + 3 = -1

-x = -4

x = 4

Now that we have found the value of x, we can substitute it back into Equation 1 to find y:

y = x - 1

y = 4 - 1

y = 3

Therefore, the solution to the system of equations is (x, y) = (4, 3).

The comparison of each expression is completed as shown below

The expanded form of log4(4 / [7x^2]) is 1 - log4(7) - 2 * log4(x)

To expand the expression log4(4 / [7x^2]), we can use logarithmic properties to simplify it. First, we can rewrite the numerator as a power of the base 4:

log4(4) - log4(7x^2)

Since log4(4) is equal to 1 (since 4 raised to the power of 1 equals 4), the expression becomes:

1 - log4(7x^2)

Next, we can apply the logarithmic property log_a(b^c) = c * log_a(b) to simplify the logarithm of a product:

1 - (log4(7) + log4(x^2))

Using another logarithmic property log_a(b^c) = c * log_a(b), we can simplify the expression further:

1 - (log4(7) + 2 * log4(x))

Therefore, the expanded form of log4(4 / [7x^2]) is:

When paying off Credit card debt, it is best to pay off high-interest credit cards

When paying off credit card debt, it is best to pay off high-interest credit cards first. High-interest credit cards typically have higher annual percentage rates (APRs) compared to other credit cards. By prioritizing the repayment of high-interest credit cards, you can minimize the amount of interest you accrue and potentially save money in the long run.

Focusing on paying off high-interest credit cards first allows you to reduce your overall debt faster. By eliminating high-interest debt, you can free up more funds to tackle other debts or allocate towards savings and investments.

It's important to note that each individual's financial situation is unique, and the best approach to paying off credit card debt may vary. Some individuals may choose to prioritize paying off credit cards with the smallest balances first (the snowball method), while others may opt for the highest interest rate (the avalanche method). It's essential to assess your financial goals and capabilities to determine the most effective strategy for your situation.

Consulting with a financial advisor or credit counseling service can provide personalized guidance and help you develop a debt repayment plan that aligns with your financial goals and circumstances.

Answer:

Step-by-step explanation: Compound interest formula = P*(1+r/n)^n*t, where:

- P = principal amount (initial investment amount).

- r = nominal annual interest rate.

- n = number of times interest is principally entered per year.

- t = number of years borrowed money.

Applying the above compound interest formula, after 10 years, you will get the amount:

= 15,000 * (1+4%/12)^(12*10) = 22363.49024

If Brenda deposits `₱15,000.00` in a savings account that pays `4%` interest compounded monthly, the accumulated interest after `10` years can be calculated using the formula for compound interest: `A = P(1 + r/n)^(nt)`, where `A` is the future value of the investment, `P` is the initial principal amount, `r` is the annual interest rate (as a decimal), `n` is the number of times the interest is compounded per year, and `t` is the number of years the money is invested for.

In this case, `P = 15000`, `r = 0.04`, `n = 12` (since the interest is compounded monthly), and `t = 10`. Plugging these values into the formula, we get:

```

A = 15000(1 + 0.04/12)^(12 * 10)

A ≈ 22265.07

```

So after `10` years, the accumulated interest would be `A - P = 22265.07 - 15000 = ₱7265.07`.

As an assessor, it is essential to objectively evaluate the Bonus payment, taking into account industry standards, the relationship between Dawa and Zeko, and compliance with tax laws.

As an assessor, it is important to approach this case with objectivity and fairness. The key factors to consider are the nature of the bonus payment, the relationship between Dawa and Zeko, and any relevant tax laws or regulations.

Firstly, it is necessary to determine if the bonus payment was reasonable and consistent with industry standards. Assessors often compare the bonus amounts given by similar enterprises in the same industry to establish a benchmark. If the bonus amount falls within a reasonable range, it is more likely to be considered as a legitimate business expense.

Secondly, the relationship between Dawa and Zeko should be evaluated. In this case, Dawa is identified as the son of Zeko, which raises questions about potential conflicts of interest or nepotism. Assessors must carefully examine whether the bonus payment to Dawa was based on his merit and contribution to the enterprise or if it was primarily due to their familial relationship. If there is evidence of favoritism or the bonus is disproportionate to Dawa's role and responsibilities, it could be deemed as personal income rather than a legitimate business expense.

Lastly, assessors need to adhere to relevant tax laws and regulations. The bonus payment should be assessed in accordance with the tax code of the jurisdiction where Zeko Enterprise operates. This involves ensuring that the appropriate taxes are paid on the bonus amount and that it is properly reported in the company's financial records.

Overall, as an assessor, it is essential to objectively evaluate the bonus payment, taking into account industry standards, the relationship between Dawa and Zeko, and compliance with tax laws. The focus should be on determining the legitimacy of the bonus payment as a business expense and ensuring that proper taxes are paid.

The difference in design and fit between left and right shoes is essential for providing comfort, support, and functionality during physical activities such as training for an obstacle course.

If Helena accidentally purchased two left shoes instead of a left and a right shoe, the comparison between the shoes would change. Instead of the right shoe looking like a reflection of the left shoe, both shoes would look the same, with neither shoe resembling a reflection of the other.

When placing the shoes on the floor next to each other, Helena would notice that both shoes have the same design, structure, and orientation. The left shoe and the right shoe would be identical, and there would be no visual distinction between them.

When Helena initially placed the shoes on the floor and observed that the right shoe looked like a reflection of the left shoe, it implied that there was a clear distinction between the left and right shoes. The right shoe would have mirrored the design and features of the left shoe, creating a symmetrical appearance.

However, if Helena had purchased two left shoes, there would be no mirror image effect or reflection between the shoes. Both shoes would appear identical and would lack the characteristic differences between left and right shoes. This means that both shoes would have the same design, features, and overall appearance.

As a result, Helena would notice that there is no shoe that corresponds to the opposite foot. When trying to wear the shoes, she would find that both shoes fit on the same foot, causing discomfort and impracticality.

In this scenario, Helena would likely realize her mistake and need to exchange or return the shoes for a proper pair with a left shoe and a right shoe. The difference in design and fit between left and right shoes is essential for providing comfort, support, and functionality during physical activities such as training for an obstacle course.

The Quadratic function has a minimum value of -8.5 at the axis of symmetry x = 2.5.

There is a minimum or maximum value to the quadratic function f(x) = 2x^2 - 10x + 4, we can look at the coefficient of the x^2 term, which is positive (2 in this case). A positive coefficient for the x^2 term indicates that the quadratic function opens upwards and has a minimum value.

To find the value of the minimum point and the axis of symmetry, we can use the formula:

Axis of Symmetry = -b / (2a)

Value at the Minimum Point = f(Axis of Symmetry)

In our quadratic function, a = 2 and b = -10. Plugging these values into the formulas, we get:

Axis of Symmetry = -(-10) / (2 * 2) = 10 / 4 = 2.5

To find the value at the minimum point, we substitute the axis of symmetry (x = 2.5) into the function:

f(2.5) = 2(2.5)^2 - 10(2.5) + 4

       = 2(6.25) - 25 + 4

       = 12.5 - 25 + 4

       = -8.5

Therefore, the minimum value of the quadratic function f(x) = 2x^2 - 10x + 4 is -8.5. The axis of symmetry is x = 2.5.

the quadratic function has a minimum value of -8.5 at the axis of symmetry x = 2.5.

The probability that a randomly chosen battery will last more than 3.664 years is 0.9673.

(a) The probability that a randomly chosen battery will last fewer than 5 years is 0.8413. This is calculated by subtracting the cumulative probability of 4.2 years (the mean life of the battery) from the cumulative probability of 5 years. We can calculate the cumulative probability using the z-score formula: z = (x - μ) / σ, where μ is the mean and σ is the standard deviation. We can also use the standard normal table to find the cumulative probability.

Z = (5 - 4.2) / 0.8 = 0.75

Cumulative probability of 5 years = 0.7734 (from the standard normal table)

Cumulative probability of 4.2 years = 0.7257 (from the standard normal table)

Therefore, the probability that a randomly chosen battery will last fewer than 5 years = 0.7734 - 0.7257 = 0.8413

(b) The probability that a randomly chosen battery will last between 1.8 and 6.6 years is 0.9545. This is calculated by subtracting the cumulative probability of 1.8 years from the cumulative probability of 6.6 years.

Z = (1.8 - 4.2) / 0.8 = -1.5

Cumulative probability of 1.8 years = 0.0668 (from the standard normal table)

Z = (6.6 - 4.2) / 0.8 = 1.75

Cumulative probability of 6.6 years = 0.9619 (from the standard normal table)

Therefore, the probability that a randomly chosen battery will last between 1.8 and 6.6 years = 0.9619 - 0.0668 = 0.9545

(c) The probability that a randomly chosen battery will last more than 3.664 years is 0.9673. This is calculated by subtracting the cumulative probability of 3.664 years from the cumulative probability of 1.

Z = (3.664 - 4.2) / 0.8 = -0.55

Cumulative probability of 3.664 years = 0.7118 (from the standard normal table)

Cumulative probability of 1 = 0.8413 (from the standard normal table)

Thus, 0.8413 - 0.7118 = 0.9673

Therefore, the probability that a randomly chosen battery will last more than 3.664 years is 0.9673.

Step-by-step explanation:

Let's break down the information provided and write out the mathematical statement step by step.

The electrician purchased 15 dimmer switches, each costing $20. This can be represented as:

Cost of dimmer switches = 15 * $20

The electrician also received a credit of $8 for each of the two duplex receptacles she returned. The total credit received can be calculated as:

Total credit = 2 * $8

To find the total amount of money she spent, we need to subtract the total credit from the cost of the dimmer switches:

Total amount spent = (Cost of dimmer switches) - (Total credit)

Now, let's calculate the total amount of money she spent:

Cost of dimmer switches = 15 * $20 = $300

Total credit = 2 * $8 = $16

Total amount spent = $300 - $16 = $284

Therefore, the electrician spent a total of $284.
