Step-by-step explanation:

When writing a proof , by copying the “given” statement(s) from the original problem

Given data ,

A true assertion that is provided in the problem or is known to be true should be the first statement in a proof. The subsequent logical argument has this as its foundation.

We can provide the groundwork for the proof and proceed to the desired conclusion by duplicating the "given" statement(s) from the original problem.

Once the first statement is established, we can move on to writing additional statements that are each logically supported by the first statement.

The logical evolution of the preceding assertions demonstrates that the last statement should be the intended conclusion.

Answer:

D

Step-by-step explanation:

Because the transformation of the quadratic equation is outside of parentheses, it can be concluded that the line is either above or below each other. Next, since we are determining how much higher of lower f(x) is according to g(x), we can determine that it is above since the f(x) is a + and g(x) is a -.

The inverse function of f(x) is:

\(g(x) = \sqrt[3]{(x +1)/64}\)

Here we have the function:

\(f(x) = 64*x^3 -1\)

We want to find the inverse, we will say that is of the form:

\(g(x) = \sqrt[3]{a*x + b}\)

If we evaluate f(x) on g(x), we get:

\(f(g(x)) = 64*(\sqrt[3]{ax + b})^3 - 1\\ \\f(g(x)) = 64*(ax + b) - 1\)

If these are inverses, that must be equal to x:

\(64*(ax + b) - 1 = x\\\\64*a*x + 64*b - 1 = x\\\)

Then:

64*a = 1

a = 1/64

64*b - 1 = 0

b = 1/64

So the inverse function is:

\(g(x) = \sqrt[3]{(x +1)/64}\)

Jane has 6 - 14 - 12 = -20 boxes of beads left.

Jane initially had 6 boxes of beads.

She used 14 of those boxes to make face mask holders and gave 12 boxes to her sister.

To find out how many boxes of beads she has left, we need to subtract the boxes used and given away from the initial number.

First, let's calculate the total number of boxes used and given away:

Total boxes used and given away = Boxes used for face mask holders + Boxes given to sister

Total boxes used and given away = 14 + 12

Total boxes used and given away = 26

Next, we can subtract the total boxes used and given away from the initial number of boxes Jane had:

Boxes left = Initial number of boxes - Total boxes used and given away

Boxes left = 6 - 26

Boxes left = -20

The result is -20, which implies that Jane has a deficit of 20 boxes of beads.

This means she doesn't have any boxes of beads left; she has a shortage of 20 boxes based on the activities she performed.

It's important to note that having a negative value indicates that Jane doesn't have enough boxes to fulfill her activities.

If the result were positive, it would represent the number of boxes remaining.

However, in this case, Jane has used and given away more boxes than she initially had, resulting in a negative value.

2 cos 35 sin 67 can be expressed as the sum of sin(102) and -sin(32).

To express 2 cos 35 sin 67 as a sum, we can use the trigonometric identity for the product of two sine or cosine functions.

Specifically, the identity states that 2 cos A sin B can be written as

sin(A + B) + sin(A - B).

Applying this identity, we have:

2 cos 35 sin 67 = sin(35 + 67) + sin(35 - 67)

Simplifying the expressions inside the sine functions:

sin(102) + sin(-32)

Since the sine function is an odd function,

sin(-x) = -sin(x),

so we can rewrite the equation as:

sin(102) - sin(32)

Therefore, 2 cos 35 sin 67 can be expressed as the sum of sin(102) and -sin(32).

Answer:

The motorist's rate is:

rate = distance / time

where distance is measured in kilometers and time is measured in hours.

We are given that the motorist travels 228 kilometers in 6 hours, so we can use this information to find the rate:

rate = distance / time = 228 km / 6 hours = 38 km/hour

To find how long it will take the motorist to travel an additional 247 kilometers at this rate, we can use the same formula and solve for time:

time = distance / rate = 247 km / 38 km/hour ≈ 6.5 hours

Therefore, it will take the motorist approximately 6.5 hours to travel an additional 247 kilometers at the same rate of 38 km/hour.

Answer:

The answer is 0.26.

I wish you luck on your assignments.

Answer: 0.26

Step-by-step explanation:

1. The hundredths place is two digits from the decimal point

2. Look at the thousandths place and if it is larger or equal to 5 then we round up, otherwise we round down and the hundredths digit remains the same

3. 7 is larger than 5 therefore the hundredths place digit of 5 rounds to a 6

4. Our final answer is 0.26

A perfect square refers to a number that is the result of multiplying an integer by itself. In this case, 6^1 is equal to 6.

However, 6 is not a perfect square because it cannot be obtained by multiplying an integer by itself. The perfect squares up to 6^1 would be 1^2 = 1 and 2^2 = 4.

Answer:

B) Annually

Step-by-step explanation:

If interest is compounded once every 12 months, it is compounded annually.

Answer:

B) Annually

Step-by-step explanation:

Compounded means to calculate interest on the borrowed amount and on previous interest.

Monthly means to be done one every month.

Annually means to be done yearly or every year.

Let's break this down. Semi means half or a partial of something. Annually, as we already discussed, means yearly or every year. Now, when we put it together, it creates half a year. So, semiannually means half a year.

We know a quarter, as in, the coin, is 25 cent. if we multiply 25 cents by four, we get a dollar. So a quarter coin is one fourth, or, a quarter of a dollar. Now, applying that to years, since a year is twelve months and a quarter is one fourth, we can divide twelve by four to get three. Three months is one quarter of a year.

With this in mind, twelve months is equal to a year. So, the interest is compounded every year.

A is incorrect because it says monthly. We have already figured out that the interest is compounded yearly, so it is incorrect.

B is correct because the definition of Annually is yearly or every twelve months.

C is incorrect because semiannually means half or part of a year, not a full year.

D is incorrect because quarterly means one fourth of a year, or, three months.

\(x = \frac{ ln(7.5) }{ ln(1.11) } = 19.31\)

Therefore , the solution of the given problem of unitary method comes out to be Daisy cream and Kremlin cream both have less cream per bulk 1 gallon and 4.5 gallons, respectively than Marble cream.

The objective can be accomplished by utilising what has already been discovered, taking advantage of this worldwide access, and including all essential components from earlier changeable study who employed a certain technique. If the anticipated claim outcome actually occurs, it will either be possible to contact the variable again or both important processes will undoubtedly miss the statement.

Here,

We must convert cups to gallons because daisy cream is sold in bulks of cups. Since a gallon of Daisy cream comprises 16 cups, one quantity of Daisy cream contains:

=> 16 cups per bulk = 1 gallon 16 cups per bulk = 1 gallon

Moscow cream is offered in bulk quantities of 4 1/2 gallons, which is one gallon.

Thus, we must convert pints to gallons. A gallon of Marble cream comprises eight pints, hence one quantity of Marble cream contains:

=> 40 pints in a bulk equal 1 gallon, 8 pints, or 5 gallons.

As a result, we can see that Marble cream, with 5 gallons per bulk, has the most cream.

Daisy cream and Kremlin cream both have less cream per bulk (1 gallon and 4.5 gallons, respectively) than Marble cream.

The probability that the sum of the numbers on your dice is 9 or 8 is 1/4.

It should be noted that to calculate the probability of rolling a 9 or 8, we can first list all the possible outcomes of rolling two six-sided dice:

1 + 1 = 2

1 + 2 = 3

1 + 3 = 4

1 + 4 = 5

1 + 5 = 6

1 + 6 = 7

2 + 1 = 3

2 + 2 = 4

2 + 3 = 5

2 + 4 = 6

2 + 5 = 7

2 + 6 = 8

3 + 1 = 4

3 + 2 = 5

3 + 3 = 6

3 + 4 = 7

3 + 5 = 8

3 + 6 = 9

4 + 1 = 5

4 + 2 = 6

4 + 3 = 7

4 + 4 = 8

4 + 5 = 9

4 + 6 = 10

5 + 1 = 6

5 + 2 = 7

5 + 3 = 8

5 + 4 = 9

5 + 5 = 10

5 + 6 = 11

6 + 1 = 7

6 + 2 = 8

6 + 3 = 9

6 + 4 = 10

6 + 5 = 11

6 + 6 = 12

There are a total of 36 possible outcomes, and we need to find the probability of rolling a 9 or 8, which corresponds 9 outcomes.

This will be;
