Whyte Clinic records an amount of $ 434100 as the cost for the land.

To purchase a land Whyte Clinic did costs:

Cost of Land is given by = $ 420000

Amount of property taxes due on the land is given by = $ 4500

The total fees for title and attorney is given by = $ 3000

The cost to grade the land is given by = $ 6600

So the total cost for the land recorded by the Whyte Clinic is given by

= $ (420000 + 4500 + 3000 + 6600)

= $ 434100

Hence Whyte Clinic records an amount of $ 434100 as the cost for the land.

Answer:

The variable d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt. d = - 38t

Step-by-step explanation:

From given, we have,  The expression that represents the Rachel's distance is given by, d = - 38t + 220                                                                      

where, d represents the distance in meters

            t represents the time in seconds                                                              

We know that, speed = distance by time.  Therefore, we need to differentiate the given equation w.r.t to time to find the speed.

we have,  d/dt (d) = d/dt [- 38t + 220]

| d/dt (d) | = | - 38 + 0 |

s =  d/dt (d) = 38 m/s

Therefore, the speed of Rachel is 38 m/s.

Answer:

38 meters per second

Answer: |t - 15| ≤ 30 ; -30 ≤ t - 15 ≤ 30

Step-by-step explanation:

To set up the equation, we have to find the center, and the tolerance, so that we can use formula "|x - c| ≤ t"

First, we can find the tolerance by adding both number, then dividing by 2 --> -15 + 45 = 30 --> 30/2 = 15, so we now know that the center is 15

Next, we can find the tolerance by finding the distance between the center and one of the number --> 15 - (-15) = 30, so we now know that the tolerance is 30

Now we can set up our equation,

center (c) = 15

tolerance (t) = 30

|t - 15| ≤ 30

Now that we have our equation, we can set up the inequality

|x - c| ≤ t = -t ≤ x - c ≤ t

so,

-30 ≤ t - 15 ≤ 30

To hide the last two rows in a table view in Swift and set their row heights to 0, you can modify the table view's delegate method `heightForRowAt` for the respective rows.

In Swift, you can achieve this by implementing the UITableViewDelegate protocol's method `heightForRowAt`. Inside this method, you can check if the indexPath corresponds to the last two rows (in this case, rows 9 and 10). If it does, you can return a row height of 0 to hide them from the view. Here's an example of how you can write this logic:

```swift

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

   let numberOfRows = tableView.numberOfRows(inSection: indexPath.section)

   if indexPath.row == numberOfRows - 2 || indexPath.row == numberOfRows - 1 {

       return 0

   }

   return UITableView.automaticDimension

}

```

In the above code, `tableView(_:heightForRowAt:)` is the delegate method that returns the height of each row. We use the `numberOfRows(inSection:)` method to get the total number of rows in the table view's section. If the current `indexPath.row` is equal to `numberOfRows - 2` or `numberOfRows - 1`, we return a height of 0 to hide those rows. Otherwise, we return `UITableView.automaticDimension` to maintain the default row height for other rows.

By implementing this logic in the `heightForRowAt` method, the last two rows in the table view will be effectively hidden from the view by setting their row heights to 0.

The solution to the inequality 13x|20 is all real numbers, as any value of x, no matter how small or large, will make the statement true.

The way to address inequity Using only real values, 13x|20. This means that there is no single solution to this inequality. The inequality is essentially asking what values of x will make the statement true. In this case, any value of x, no matter how small or large, will make the statement true. This is because the absolute value of x is being taken, which means that the value of x is being evaluated regardless of the sign--whether it is positive or negative. For example, if x is -1, then 13x|20 would be 13(-1)|20, which simplifies to -13|20, or 20. This means that no matter what the value of x is, it will always make the statement true. Therefore, the solution to the inequality is all real numbers.

The output of a classification system is usually a discrete value, usually a label or class, which represents the predicted result of the model.

A classification system can be expressed mathematically using a decision boundary. This boundary is defined by a decision function that maps the input data to a discrete output. The decision boundary is determined by setting a threshold for the output of the decision function, such that if the output exceeds the threshold, the predicted class is labeled as a "positive" output and if the output is below the threshold, the predicted class is labeled as a "negative" output.

The output of a regression system is usually a continuous value, which represents the predicted result of the model. A regression system can be expressed mathematically using a linear equation which maps the input data to a continuous output. The equation is determined by fitting a line to the data, such that the line best fits the data points. The value of the output is then calculated by evaluating the equation at a given point in the input data.

Mark sets aside $404 for more supplies.

Mark spent $175 on supplies, so his total cost is $175.

Mark sold 6 pieces of artwork for $70 each, so he earned 6 * $70 = $420 from these pieces.

He sold 15 - 6 = 9 pieces of artwork at $85 each, so he earned 9 * $85 = $765 from these pieces.

His total revenue is $420 + $765 = $1185.

His profit is his revenue minus his cost: $1185 - $175 = $1010.

IQR is the difference of the above two numbers:

Correct choice s D

Answer:

D.  9 - 4 = 5

Step-by-step explanation:

Given data set:  1, 4, 5, 6, 6, 9, 11

To find the Interquartile Range (IQR):

Step 1

Place the data values in order from smallest to largest:

1, 4, 5, 6, 6, 9, 11

Step 2

To find the position of the lower quartile, count how many data values there are, add 1, and divide by 4:

\(\implies \sf \textsf{Position of lower quartile}= \dfrac{7\:data\:values+1}{4}=2nd\:position\)

Therefore, the lower quartile is 4.

Step 3

To find the position of the upper quartile, count how many data values there are, add 1, multiply by 3, and divide by 4:

\(\implies \sf \textsf{Position of upper quartile}= \dfrac{(7\:data\:values+1) \times 3}{4}=6th\:position\)

Therefore, the upper quartile is 9.

Step 4

\(\begin{aligned}\textsf{Interquartile range (IQR)} & = \textsf{upper quartile} - \textsf{lower quartile}\\& = \sf 9-4\\& = \sf 5 \end{aligned}\)

Let W be the rectangle's width and L its length.

The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be

Area of the rectangle = L × W square units

The length of a rectangular poster is 2 more inches than two times its width. The area of the poster is 112 square inches. Then the equations are given as,

LW = 112           ...1

L = 2W + 2       ...2

From equations 1 and 2, then we have

(2W + 2)W = 112

2W² + 2W - 112 = 0

W² + W - 56 = 0

W² + 8W - 7W - 56 = 0

W(W + 8) - 7(W + 7) = 0

(W + 8)(W - 7) = 0

W = 7, -8

The number of bacteria will double after 15.93 hours, or approximately 15 hours and 56 minutes.

The given exponential growth equation for N(t) is N(t) = 10000011.

To solve the problems related to it, we need to follow these steps:a) What is the number of bacteria at t = 0 hours?

We need to plug in t = 0 in the given equation of N(t) to find out the number of bacteria at t

= 0 hours.

N(0) = 10000011

= 1

Therefore, the number of bacteria at t = 0 hours is 1.b) When will the number of bacteria double?

Give the exact solution in the simplest form. Do not evaluate.

We know that the formula for the exponential growth function is given by the equation y = abx.

Here, x is the number of units of time passed, a is the initial value of y, b is the growth factor, and y is the final value of the function. We can use this formula to find out the time when the number of bacteria doubles.To find out the time when the number of bacteria doubles,

we can set y = 2 and s

olve for x.2 = abx

Since we are given that

N(t) = 10000011, we can write the above equation as:

2 = 10000011 * bxTaking the natural logarithm of both sides,

ln 2 = ln 10000011 + ln bx

Simplifying,

ln 2 - ln 10000011 = ln b + x ln b

Using a calculator, we get,

ln b = ln 2 - ln 10000011ln b

≈ -20.723

Using the properties of logarithms, we get,

x = [ln 2 - ln 10000011] / ln bSubstituting the value of ln b,

we get,x ≈ 15.93
