Answers

Answer 1
Point, domain, range.
Answer 2

Each point on the coordinate plane has an address, called the coordinates.

What is Coordinate Plane?

The coordinate plane is a two-dimension surface formed by two number lines. One number line is horizontal and is called the x-axis. The other number line is vertical number line and is called the y-axis.

The coordinate plane is a two-dimension surface formed by two number lines.

A coordinate plane, also known as a rectangular coordinate plane grid, is a two-dimensional plane formed by the intersection of a vertical line called the Y-axis and a horizontal line called the X-axis.

One number line is horizontal and is called the x-axis.

The other number line is vertical number line and is called the y-axis.

The two axes meet at a point called the origin.

Hence, Each point on the coordinate plane has an address, called the coordinates.

Suppose 4 mg of a drug is injected into a person's bloodstream. As the drug is metabolized, the quantity diminishes at the continuous rate of 3% per hour?

Answers

Let Q(t) = the mass (mg) remaining after t hours.
We are told that Q diminishes by 3% every hour.

When t = 0, Q = 4 mg
When t = 1,  Q = 4*0.97 mg
When t = 2, Q = 4*(0.97)² mg

By induction,
[tex]Q(t) = 4 (0.97)^{t} \, mg[/tex]

Q'(t) = 0.97Q
Therefore the rate of decrease is 3% per hour.

The person receives an additional dosage when Q falls to 0.50 mg. This happens when
[tex]4(0.97)^{t}=0.5 \\0.97^{t} = 0.125 \\ t \,ln(0.97) = ln(0.125) \\ t = \frac{ln(0.125)}{ln(0.97)} =68.27 \, hrs[/tex]

After the second injection, the mass is now 4.5 mg. Therefore
[tex]Q(t)=4.5(0.97)^{t}[/tex]

When the mass again reaches 0.50 mg, then
[tex]4.5(0.97)^{t}=0.5 \\ 0.97^{t}=0.1111 \\ t \, ln(0.97) = ln(0.1111) \\ t = 72.14 \, hrs[/tex]

There are 56 trees in an apple orchard. They are arranged in equal rows. There are 8 trees in each row. How many rows of apple trees are there? Which equation can be used to solve this problem?

Answers

Final answer:

In this case, there are 56 trees in the orchard and 8 trees in each row, so there are 7 rows of apple trees in the orchard.

Explanation:

To find the number of rows of apple trees in the orchard, we need to divide the total number of trees by the number of trees in each row.

In this case, there are 56 trees in the orchard and 8 trees in each row.

We can use the equation:

Number of rows = Total number of trees / Number of trees in each row

Plugging in the values:

Number of rows = 56 trees / 8 trees = 7 rows

Therefore, there are 7 rows of apple trees in the orchard.

Answers

To find the area of the curve subject to these constraints, we must take the integral of y = x ^ (1/2) + 2 from x=1 to x=4
Take the antiderivative: Remember that this what the original function would be if our derivative was x^(1/2) + 2 
antiderivative (x ^(1/2) + 2) =  (2/3) x^(3/2) + 2x
* To check that this is correct, take the derivative of our anti-derivative and make sure it equals x^(1/2) + 2

To find integral from 1 to 4:
Find anti-derivative at x=4, and subtract from the anti-derivative at x=1
2/3 * 4 ^ (3/2) + 2(4) - (2/3) *1 - 2*1
2/3 (8) + 8 - 2/3 - 2                               Collect like terms

Which figures can be precisely defined by using only undefined terms? Check all that apply.

Answers

If my memory seves me well, angle, parallel lines figures which can be precisely defined by using only undefined terms are angle and parallel lines.

Answer:

We can define circle, line segment and parallel lines with the help of undefined terms.

Step-by-step explanation:

The undefined terms in geometry are line, plane and points.

So, we can define line segment, circles and parallel lines with the help of undefined terms.

A line segment is a part of a line that contains two distinct end points.

A circle is defined as a figure with a set of points that are all equidistant from a fixed point called the center.

Parallel lines are lines in a plane that never meet or intersect at any point.

The value of the expression [tex]\( 56 - \left( \frac{18}{34} \right) \)[/tex] as a fraction in simplest form is [tex]\( \frac{943}{17} \)[/tex].

To solve the expression, we first perform the division within the parentheses:

[tex]\[ \frac{18}{34} \][/tex]

This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2:

[tex]\[ \frac{18 \div 2}{34 \div 2} = \frac{9}{17} \][/tex]

Now we have:

[tex]\[ 56 - \frac{9}{17} \][/tex]

We need to express the whole number as a fraction with the same denominator as the fraction we are subtracting.

[tex]\[ \frac{56 \times 17}{17} - \frac{9}{17} \][/tex]

[tex]\[ \frac{952}{17} - \frac{9}{17} \][/tex]

Answers

It's between 101 and 199.

5 less than 10 is 5.
2 more than 5 is 7

My guess is 157

The correct number is between 100 and 200 would be 175.

Used the concept of number system which states that,

A writing system used to express numbers is known as a number system. It is the mathematical notation used to consistently express the numbers in a particular set using digits or other symbols.

Given that,

A number is less than 200 and greater than 100.

Here, the one's digit is 5 less than 10, and the tens digit is 2 more than the one digit.

Since the one's digit is 5 less than 10.

So, the number in one's place is,

10 - 5 = 5

And, the tens digit is 2 more than the one digit.

5 + 2 = 7

Since the number is between 100 and 200.

So, the possible value of a number with the value in one's place 5 and the value in tens place 7 would be,

175

Clearly, the number 175 is between 100 and 200.

There is not enough information given to compare weekly earnings.

Answers

First, we must calculate the weekly pay of an employee that is paid a fixed amount. Given that there are 52 weeks in a year, the weekly pay for a regularly paid employee is: 67,000 / 52 = $1,288.46 Now, we calculate the number of hours an employee that is paid hourly works per week: 0 + 10 + 8 + 8 + 7 + 6.5 + 4.5 = 44 So this employee is paid: 25 x 40 + 37.5 x 4 = $1,150 Therefore, it is recommended that a new employee goes for the salaried pay since the weekly earnings are greater in this option.

The UCL and LCL for the mean and range charts are calculated based on the average and range of the data sets. The table provided in the question provides respective factors for various subgroup sizes. For n=5, the factors are A2=0.58, D3=0 and D4=2.11. Using these we compute UCL and LCL for both charts. Round off to two decimal places and fill '0' in any empty cells.

Explanation:

To find the Upper Control Limit (UCL) and Lower Control Limit (LCL) for the mean and range charts, we have to use the r and formula179.mml charts that are provided in your question. We will take the observations in groups of five as mentioned in the question.

Firstly, calculate the average (X-bar) for each of these groups and find the overall average (M) of these five averages.Please find the range (R) for each subgroup and then the average of these ranges (meanR).Referring to the table given in your question, for n=5, the factors are A2=0.58, D3=0 and D4=2.11.The UCL and LCL for the mean chart can be calculated using UCL=M+A2*meanR and LCL=M-A2*meanR, whereas, for the range chart, they are UCL=D4*meanR and LCL=D3*meanR

Using these steps, you can find the upper and lower control limits for both the mean and range charts. Always remember to round off your answers to two decimal places and also, to avoid leaving any cells blank in the excel sheet. If required, fill in  '0' in those empty cells.

The upper and lower control limits for the mean chart are 81.06 and 78.86, respectively, while the upper control limit for the range chart is 8.45 and the lower control limit is 0.

To determine the upper and lower control limits for the mean and range charts, we can use the factors provided in the table.

For the mean chart:

- The upper control limit (UCL) is calculated by adding the product of the factor for the mean chart (A2) and the average range (R-bar) to the overall average (X-double-bar). In this case, the A2 factor is 0.73 and the R-bar is 4.01, so the UCL for the mean chart is: 81.06 (rounded to 2 decimal places).

- The lower control limit (LCL) is calculated by subtracting the product of the factor for the mean chart (A2) and the average range (R-bar) from the overall average (X-double-bar). Using the same values, the LCL for the mean chart is: 78.86 (rounded to 2 decimal places).

For the range chart:

- The UCL for the range chart is calculated by multiplying the factor for the range chart (D4) by the average range (R-bar). In this case, the D4 factor is 2.11 and the R-bar is 4.01, so the UCL for the range chart is: 8.45 (rounded to 2 decimal places).

- The LCL for the range chart is always 0 since range values cannot be negative.
