Answer:

x^3 + 2x - 1.

Step-by-step explanation:

To simplify the expression 2x + x^3 - 1, we can first rearrange the terms in decreasing order of the exponents:

x^3 + 2x - 1

So the simplified expression, rearranged in descending order, is x^3 + 2x - 1.

Y = -5x + 3 is the equation represents a line which is parallel to the line Y = -5x - 7 with y intercept 3

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We have to find the equation which  represents a line which is parallel to the line Y = -5x - 7 with y intercept 3

The correct statement that F: "I agree. The ratios of consecutive x-values are constant, and the y-values are increasing at a constant rate."

To determine whether the function shown in the table is exponential, we need to analyze the relationship between the x-values and y-values.

The table shows x-values that are increasing by a power of 2 (1, 2, 4, 8, 16, 32, 64) and y-values that are increasing by a constant rate of 1 (0, 1, 2, 3, 4, 5, 6).

The constant ratio between consecutive x-values indicates exponential growth or decay.

In this case, the function is growing exponentially because the y-values are increasing at a constant rate.

Based on this information, we can conclude that the function is exponential.

Therefore, we agree with statement F: "I agree. The ratios of consecutive x-values are constant, and the y-values are increasing at a constant rate."

The other statements are incorrect because they do not accurately describe the relationship between the x-values and y-values in an exponential function.

Answer:

  (x, y) = (3, 4)

Step-by-step explanation:

You want to solve the system of equations by combining the equations:

The coefficients of x have the same value (1), so we can eliminate x by multiplying one of the equations by -1 and adding the result. Since we want the resulting coefficient of y to be positive, we choose to multiply the first equation by -1.

  [tex]\begin{array}{c,l,l,l}-1&(x&-y&=-1)\\+1&(x&+8y&=35\,)\end{array}[/tex]

Then the sum is ...

  [tex]\begin{array}{rcl}-x&+y&=1\\x&+8y&=35\\\cline{1-3}0x&+9y&=36\end{array}[/tex]

The solution to this is ...

  y = 36/9 = 4

  x = y -1 = 4 -1 = 3 . . . . . . from the first equation

Answer:

156.76 days (approx.)

Step-by-step explanation:

To calculate the Cash Cycle, we need to consider the time it takes for a company to convert its investment in inventory and receivables back into cash. The formula for Cash Cycle is as follows:

Cash Cycle = Inventory Conversion Period + Receivables Collection Period - Payables Deferral Period

Now, let's calculate each component of the Cash Cycle using the given information.

1. Inventory Conversion Period:

Inventory Conversion Period measures the average number of days it takes to convert raw materials into finished goods.

Average Inventory = (Opening Raw Material + Closing Raw Material) / 2

= (4,00,000 + 5,00,000) / 2

= 4,50,000

Manufacturing Costs per day = Manufacturing Costs / 360 days

= 10,45,000 / 360

= 2,902.77 (approx.)

Inventory Conversion Period = Average Inventory / Manufacturing Costs per day

= 4,50,000 / 2,902.77

≈ 155 days

2. Receivables Collection Period:

Receivables Collection Period measures the average number of days it takes to collect payments from customers.

Average Receivables = (Opening Debtors + Closing Debtors) / 2

= (2,50,000 + 3,15,000) / 2

= 2,82,500

Sales per day = Total Sales / 360 days

= 4,20,00,500 / 360

= 1,16,666.67 (approx.)

Receivables Collection Period = Average Receivables / Sales per day

= 2,82,500 / 1,16,666.67

≈ 2.42 days

3. Payables Deferral Period:

Payables Deferral Period measures the average number of days the company takes to pay its suppliers.

Average Payables = (Opening Creditors + Closing Creditors) / 2

= (5,60,000 + 6,25,000) / 2

= 5,92,500

Purchases per day = Total Purchases / 360 days

= 3,23,00,000 / 360

= 8,97,222.22 (approx.)

Payables Deferral Period = Average Payables / Purchases per day

= 5,92,500 / 8,97,222.22

≈ 0.66 days

Now, we can calculate the Cash Cycle using the formula mentioned earlier:

Cash Cycle = Inventory Conversion Period + Receivables Collection Period - Payables Deferral Period

= 155 days + 2.42 days - 0.66 days

≈ 156.76 days (approx.)

Therefore, the Cash Cycle is approximately 156.76 days based on the given information.

Ryan's Social Security retirement benefit, computed using the given formula, is $2,188.89 per month.

To calculate Ryan's Social Security retirement benefit, we'll break it down into three parts based on the given formula:

First, we shall estimate 90% of the first $926 of Ryan's average monthly earnings:

Benefit from level 1= 0.9 * $926

Next, we find out 32% of  the amount between $926 and $5,583:

Benefit from level 2= 0.32 * ($5,583 - $926)

Lastly, we compute 15% of the amount over $5,583:

Benefit from level 3= 0.15 * (Ryan's average monthly earnings - $5,583)

Ryan's retirement benefit is the sum of the benefits from all three level:

Retirement benefit = Benefit from level 1 + Benefit from level 2 + Benefit from level 3

Benefit from level 1:

= 0.9 * $926 = $833.40

Benefit from level 2:

= 0.32 * ($5,583 - $926) = 0.32 * $4,657 = $1,489.44

Benefit from level 3:

= 0.15 * (Ryan's average monthly earnings - $5,583)

= 0.15 * ($4,690 - $5,583)

= 0.15 * (-$893)

= -$133.95 (Ryan's average monthly earnings are less than $5,583, this amount is negative)

We now calculate the retirement benefit:

Retirement benefit = Benefit from level 1 + Benefit from level 2 + Benefit from level 3

= $833.40 + $1,489.44 - $133.95

= $2,188.89

Therefore, Ryan's Social Security retirement benefit is $2,188.89 per month.

Answer:

To solve the system of equations:

2/3x + 3/5 y = 12 --- equation (1)

5/2y - 3x = 6 --- equation (2)

We can use the method of substitution or elimination. Here, we will use the elimination method to eliminate one variable and solve for the other.

Multiplying equation (1) by 5 and equation (2) by 3, we get:

10/3x + 9/5y = 60 --- equation (3) obtained from (1) by multiplying both sides by 5

15/2y - 9x = 18 --- equation (4) obtained from (2) by multiplying both sides by 3

Now, we can eliminate y by multiplying equation (3) by 10/9 and adding it to equation (4):

(10/3x + 9/5y) x 10/9 + (15/2y - 9x) = 0

Simplifying this equation, we get:

20x/9 - 27x/5 = -100/3

Multiplying both sides by 45, we get:

20x(5) - 27x(9) = -1500

Simplifying and solving for x, we get:

-65x = -1500

x = 23.08 (rounded to two decimal places)

Substituting x = 23.08 into equation (1), we can solve for y:

2/3(23.08) + 3/5 y = 12

15.39 + 0.6y = 12

0.6y = -3.39

y = -5.65 (rounded to two decimal places)

Therefore, the solution to the system of equations is x = 23.08 and y = -5.65.

So, the solution to the system of equations is (23.08, -5.65).

The percentage strength of the compound is approximately 1.96%.

We have,

To determine the percentage strength of the compound, we need to calculate the ratio of the mass of the active ingredient (hydrocortisone powder) to the total mass of the compound and express it as a percentage.

Given:

Mass of hydrocortisone powder = 3 g

Mass of petrolatum = 150 g

Total mass of the compound

= Mass of hydrocortisone powder + Mass of petrolatum

= 3 g + 150 g = 153 g

To calculate the percentage strength, we divide the mass of the hydrocortisone powder by the total mass of the compound and multiply by 100:

Percentage strength = (Mass of hydrocortisone powder / Total mass of the compound) x 100

Percentage strength = (3 g / 153 g) x 100

Percentage strength ≈ 1.96%
