The expression of logarithmic function, f(x) = ln (1/gᵏ) after all possible expansion is equals to the f(x) = - k × ln( g).

In mathematics, the logarithmic function is defined as inverse function to exponent function and defined as f(x) = logₐx where a is base of function. Properties of Logarithmic Functions :

We have, a natural logarithmic function, i.e., base = 10, f(x) = ln (1/gᵏ) and we have to expand it. To expand logarithms means write them as a sum or difference product of logarithms. The order to apply rules is quotient rule, product rule and then power rule. So, f(x) = ln (1/gᵏ)

applying quotient rule,

=> f(x) = ln(1) - ln( gᵏ)

Appling power rule,

=> f(x) = ln(1) - k ln( g)

Applying Zero Exponent Rule,

=> f(x) = 0 - k × ln( g)

Hence, the required expansion is f(x) = - k × ln( g).

Answer:

Domain: {1,2,4}

Step-by-step explanation:

The domain is the input values

We normally list the value in order from smallest to largest and only list the values one time if they appear more than once

Domain: {1,2,4}

Take the input values as domain.

→ 2,1,2,4

Now pick a number once if it is repeated and arrange in ascending order.

Then the domain will be,

→ 1,2,4

Hence, {1,2,4} is the domain of the pairs.

(a) To compute the experimental probability of rolling a 1 or 6 from Latoya's results, we need to determine the number of times a 1 or 6 was rolled and divide it by the total number of rolls Latoya made.

Let's assume that Latoya rolled the dice 100 times and obtained 20 1's and 10 6's. The total number of successful outcomes (rolling a 1 or 6) is 20 + 10 = 30.

Therefore, the experimental probability of rolling a 1 or 6 is 30/100 = 0.3 or 30%.

(b) Assuming the cube is fair, the theoretical probability of rolling a 1 or 6 can be determined by considering the favorable outcomes (rolling a 1 or 6) divided by the total possible outcomes (rolling any number from 1 to 6).

Since there are two favorable outcomes (1 and 6) out of six possible outcomes (1, 2, 3, 4, 5, 6), the theoretical probability is 2/6 = 1/3 or approximately 0.3333.

(c) The correct statement is B. As the number of rolls increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal. This is due to the law of large numbers, which states that as more trials are conducted, the experimental probability tends to converge towards the theoretical probability. However, it is not necessary for them to be exactly equal. Random variations can cause some discrepancy, but with a larger number of rolls, the experimental probability should approach the theoretical probability more closely.

Answer:

Step-by-step explanation:

the degree of a polynomial determines 1:1 the number of solutions.

a quadratic equation (degree 2) has 2 solutions.

the general solution is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = -4

b = -4

c = -1

so,

x = (4 ± sqrt((-4)² - 4×-4×-1))/(2×-4)

when we look at the square root

16 - 16

we see that it is 0.

the square root of 0 is 0, and there is no difference between -0 and +0.

so, we get only one (real) solution : 4/-8 = -1/2

but : formally, there are still 2 solutions (as this is a quadratic equation). they are just identical.

The angles x and 148° are vertical angles and si the measure of the vertical angle x is equal to 148°.

Vertical angles also called vertically opposite angles are formed when two lines intersect each other, the opposite angles formed by these lines are vertically opposite angles and are equal to each other.

The angles 148° and x form vertical angles, so x = 148°

The revised Doubtful Debts Provision should be, $4,555.

Now, Using a net debtors value of $91,100 and a provision rate of 5%, use the calculation to get the adjusted Provision for Doubtful Debts (PDD):

Net Debts x Provision Rate equals Adjusted PDD.

The computation would then be:

= $91,100 x 0.05

= $4,555 is the adjusted PDD.

Because of the additional $550 in bad debt and the revised net debtors value of $91,100, the Provision for Doubtful Debts must be raised by ,

= $4,555 - $3,500

= $1,055

What is unit conversion?

Unit conversion is the process of converting a quantity expressed in one unit of measurement to an equivalent quantity expressed in another unit of measurement.

We can convert mm² to cm² by dividing the area in mm² by the square of the conversion factor, which is (10 mm / 1 cm) = 100 mm² / cm². Therefore, we have:

11700 mm² / (100 mm² / cm²) = 117 cm²

3/4 divide by 9 = 0.75/9 = 0.083 yard for each doll's hair ribbon

Step-by-step explanation:

Each doll's hair ribbon will be 0.083 (yards)

The length of each of the daughter's dolls hair ribbon is \(\frac{1}{12} \ yards\)

The given parameters:

amount of ribbon Kristen has \(= \frac{3}{4}\) yards

number of her daughter's dolls = 9

To find:

To have equal length of ribbons for each of the doll's hair, we divide the total amount of ribbons by 9, since there 9 dolls.

\(Length \ of \ each \ doll's \ ribbon = (\frac{3 }{4} \times \frac{1}{9})\ yards\\\\Length \ of \ each \ doll's \ ribbon = (\frac{3}{36} ) \ yards\\\\Length \ of \ each \ doll's \ ribbon = \frac{1}{12} \ yards\)

Value of Vertical Analysis;

⇒ Net sales = 100%

⇒ Earnings before taxes = 5.6%

⇒ Net earnings = 3.4%

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Now, We can find as;

Horizontal Analysis:

Here, Calculate the dollar change by subtracting the previous year's figure from the current year's figure for each item:

Net sales = $40,580 million - $35,475 million

              = $5,105 million increase

Earnings before taxes = $2,291 million - $1,313 million

                                  = $978 million increase

Net earnings = $1,378 million - $921 million

                    = $457 million increase

Hence, Calculate the percentage change by dividing the dollar change by the previous year's figure and multiplying by 100 as;

Net sales = ($5,105 million / $35,475 million) x 100

               = 14.4% increase

Earnings before taxes = ($978 million / $1,313 million) x 100

                                  = 74.4% increase

Net earnings = ($457 million / $921 million) x 100

                   = 49.6% increase

And, Vertical Analysis:

Calculate the percentage of each item in relation to the net sales by dividing each item by the net sales and multiplying by 100:

Net sales = $40,580 million / $40,580 million x 100

               = 100%

Earnings before taxes = $2,291 million / $40,580 million x 100

                                  = 5.6%

Net earnings = $1,378 million / $40,580 million x 100

                    = 3.4%

Thus, Value of Horizontal Analysis:

⇒ Net sales = 14.4%

⇒ Earnings before taxes = 74.4%

⇒ Net earnings = 49.6%

Value of Vertical Analysis;

⇒ Net sales = 100%

⇒ Earnings before taxes = 5.6%

Answer:

We'll start with the left-hand side (LHS) of the identity, which is:

sin x (1 + cot^2 x)

We can rewrite cot^2 x as (cos x / sin x)^2, since cotangent is the reciprocal of tangent. Substituting this into the LHS, we get:

sin x (1 + (cos x / sin x)^2)

Now we can simplify the expression in the parentheses by using the identity:

tan^2 x + 1 = sec^2 x

Rearranging this identity, we get:

tan^2 x = sec^2 x - 1

Substituting this into our expression, we get:

sin x (1 + (cos x / sin x)^2) = sin x (1 + (cos^2 x / sin^2 x))

= sin x (sin^2 x / sin^2 x + cos^2 x / sin^2 x)

= sin x ((sin^2 x + cos^2 x) / sin^2 x)

= sin x (1 / sin^2 x)

= sin x / sin^2 x

= 1 / sin x

Now we'll simplify the right-hand side (RHS) of the identity, which is:

csc x

We know that csc x is the reciprocal of sin x, so we can rewrite the RHS as:

1 / sin x

This is the same as the expression we obtained for the LHS, so we have shown that:

sin x (1 + cot^2 x) = csc x

And this proves the identity!

Remember, when you're proving trigonometric identities, it's important to be familiar with the fundamental trigonometric identities and the basic algebraic rules of manipulating equations

Answer: y=1.25

Step-by-step explanation:

First things first you have to find what is in the bracket things (i don’t know what it’s called) So 3 - 7 is -4y but since it’s absolute it’s going to be 4y.

So now you’ve got 4y - 10 = -5. Your going to want to eliminate 10 so, subtract 10 to both sides giving you 4y = -5

Lastly to get y by itself you need to divide it by its self so, 4y divided by 4. Do it to both sides. This gives you…
