Answer:

a (a - b)

Step-by-step explanation:

\(2a^{2}-3ab+b^{2} from 3a^{2} + 2ab - b^{2}\)

Now, as \(2a^{2}-3ab+b^{2}\) is from \(3a^{2} + 2ab - b^{2}\)

so it will be subtracted :

\(3a^{2} + 2ab - b^{2}\) \(-2a^{2}-3ab+b^{2}\)

= \(a^{2} - ab\)

= a (a - b)

Step-by-step explanation:

The circumference of a WHOLE circle = pi * d

   you have 1/2 of this  and d = 10 ft

     so   1/2 pi * 10      PLUS the two straight sides + 8+6

       1/2 pi * 10   + 8 + 6

         5 pi + 8 + 6

        5 * 3.14   + 14 = 29.7 ft

Step-by-step explanation:

multiply like normal math . then add the decimal point after 1 number

To determine the function that models the data, we need to analyze the relationship between the cost per photo and the number of photos a customer buys. From the given information, we can observe that the cost per photo varies inversely with the number of photos. This implies that as the number of photos increases, the cost per photo decreases, and vice versa.

To model this relationship, we can use the inverse variation equation, which can be expressed as:

y = k/x

Here, y represents the cost per photo, x represents the number of photos, and k is the constant of variation.

Let's examine the data given in the table to find the value of k:

Number of Photos (x) Cost per Photo (y)

10 10

25 4

50 2

100 1

We can see that as the number of photos increases, the cost per photo decreases. We can use any pair of values from the table to solve for k. Let's choose the pair (50, 2):

2 = k/50

Solving for k:

k = 2 * 50 = 100

Now that we have the value of k, we can write the function that models the data:

y = 100/x

Therefore, the function that models the data is y = 100/x, where y represents the cost per photo and x represents the number of photos a customer buys.

Answer:

\( \frac{x}{18} \)

Step-by-step explanation:

\( \frac{x}{60} \times \frac{x}{30} = \frac{x}{1800} \\ \\ \frac{x}{1800} \times 100 \\ \\ x = \frac{1}{18} \)

Answer:

11/4     0.75    60%    1/2     0.2

Step-by-step explanation:

Given

11/4  0.2   60%   0.75   1/2

Required

Order from largest to smallest

Convert all numbers to decimal

\(11/4 = 2.75\) ; \(60\% = 0.60\) and \(1/2 = 0.50\)

So, the numbers are:

2.75    0.2     0.60     0.75     0.50

From largest to least, we have:

2.75    0.75     0.60   0.50   0.2

Convert all numbers back to their original form

11/4     0.75    60%    1/2     0.2

For the forecasting process to be effective, internal data should be highly disaggregated

Predicting the future based on historical and current facts is the forecasting process. The most popular method for doing this is trend analysis. It is typically ideal to use internal data that is significantly disaggregated for forecasting to be successful. This means that rather than aggregating or summarizing the data at a high level, it should be broken down into as much detail as feasible.

Since highly disaggregated data presents a more complete and precise picture of the variables that may impact future events, forecasting can be done more accurately and dependably. This can include information about previous sales, manufacturing rates, inventory levels, costs, and other elements that can be important for forecasting. Whereas, using highly aggregated data can lead to less accurate and reliable forecasts, as it may not capture the full range of factors that may influence future outcomes.

The domain of the function or relation is {6, 9, -4 and 2}

The function is represented by the set of relation or ordered pairs

The ordered pairs in the relation are:

(x, y)  = (6, -3), (9, -3), (-4, 1) and (2, 1)

Remove the y values in the above domain

x = 6, 9, -4 and 2

Answer:

y=37

Step-by-step explanation:

the addition of the 3 angles is 180°

then 40 + y +29 +2y  = 180

        69 + 3y =180

        3y  = 180 -69

        3y= 111

        y =111 ÷ 3

        y = 37

Step-by-step explanation:

x = -4,

f(4) = -3(-4) + 15

= 12 + 15

= 27

f(0) = -3(0) + 15

= 0 + 15

= 15

f(5) = -3(5) + 1 5

=- 15 + 15

= 0

Answer:

20° and 70°

Step-by-step explanation:

complimentary angle sum to 90°

let x be the compliment then the angle is 3x + 10 , so

x + 3x + 10 = 90 , that is

4x + 10 = 90 ( subtract 10 from both sides )

4x = 80 ( divide both sides by 4 )

x = 20

3x + 10 = 3(20) + 10 = 60 + 10 = 70

the 2 angle measures are 20° and 70°

Answer:

Is 03.841

Step-by-step explanation:

To find the critical value needed to test the claim that the sentence is independent of the plea, we need to perform a chi-square test of independence. The critical value is based on the significance level (α) and the degrees of freedom.

In this case, the given significance level is 0.05. Since the table represents a 2x2 contingency table (two categories for plea and two categories for sentence), the degrees of freedom (df) can be calculated as (number of rows - 1) * (number of columns - 1) = (2 - 1) * (2 - 1) = 1.

To find the critical value at a significance level of 0.05 with 1 degree of freedom, we consult a chi-square distribution table or use statistical software.

The critical value for a chi-square test with 1 degree of freedom and a significance level of 0.05 is approximately 3.841.

Therefore, the correct answer is 03.841.

Answer:

\(4x+1=e^\frac{3}{7}\)

Step-by-step explanation:

Important log rule required to solve the following question:

\(ln(N)=x-- > N=e^x\)

Given the following logarithmic equation,  \(ln(4x+1)=\frac{3}{7}\), we'd like to convert it to exponential.
Firstly, "ln" is replaced with "e"

On one side of the exponential equation we have "N" which stands for what's inside of the parenthesis of natural log; in other words (4x+1). So on one side of the exponential equation we have 4x + 1

\(4x+1=e^x\)

Finally, according to the rule, we must replace the "x" with what the natural log is equal to (3/7).

\(4x+1=e^\frac{3}{7}\)

And we are done!

\(ln(N)=x-- > N=e^x\\ln(4x+1)=\frac{3}{7} -- > 4x+1=e^\frac{3}{7}\)

Answer:

(assuming we're deciding decimals by decimals)

Dividing decimals is alot like regular decimal dividing. First, you must move the decimal places so it becomes a whole number. This makes it easier and less confusing as steps go on. Now we can divide regularly as we go on, making sure to put the amount of decimal spots we moved back in the answer.

Answer:

The first step is to make the divisor a whole number by multiplying it by a power of 10. When you multiply the divisor by a power of 10, you must multiply the dividend by the same power of 10. Then divide. Check your answer using estimation.
