To factor the expression3x^2 - 5x - 18x + 30, we can group the terms and then factor out common factors.

Step 1: Group the terms.

3x^2 - 5x - 18x + 30,

Step 2: Factor out the common factors from each group.

x(3x - 5) - 6(3x - 5)

Step 3: Notice that we now have a common binomial factor of (3x - 5).

(3x - 5)(x - 6)

Therefore, the factored form of the expression 3x^2 - 5x - 18x + 30 is (3x - 5)(x - 6).

In this factored form, (3x - 5) and (x - 6) are the factors of the expression. To check if the factoring is correct, you can multiply the factors back together to see if you get the original expression:

(3x - 5)(x - 6) = 3x(x) - 3x(6) - 5(x) + 5(6)

=3x^2 - 18x - 5x + 30

= 3x^2 - 23x + 30  

The result matches the original expression, so the factoring is correct.

Therefore, the factored form of 3x^2 - 5x - 18x + 30 is (3x - 5)(x - 6).

The equation of the tangent line at (3, 324) is y = 288x - 540.

To find y' (the derivative of y), we can differentiate the given function y = [tex](x^2 + 2x + 3)^2[/tex] using the chain rule.

y' = [tex]2(x^2 + 2x + 3) \times (2x + 2) = 4(x^2 + 2x + 3)(x + 1)[/tex]

Now, to find the slope of the tangent line at (3, 324), we substitute x = 3 into y' and evaluate it:

y' = [tex]4(3^2 + 2(3) + 3)(3 + 1) = 4(9 + 6 + 3)(4) = 4(18)(4) = 288[/tex]

So, the slope of the tangent line at (3, 324) is 288.

To find the y-intercept of the tangent line, we substitute the coordinates (3, 324) and the slope (288) into the point-slope form equation: y - y1 = m(x - x1).

Using (x1, y1) = (3, 324) and m = 288, we have:

y - 324 = 288(x - 3)

y - 324 = 288x - 864

y = 288x - 540

Therefore, the equation of the tangent line at (3, 324) is y = 288x - 540.

Answer:

The probability that on a particular week, the hospital will receive on high BP pregnant woman is 0.0068

Step-by-step explanation:

We use the Exponential distribution,

Since we are given that on average, 5 pregnant women with high blood pressure come per week,

So, average = m = 5

Now, on average, 5 people come every week, so,

5 women per week,

so, we get 1 woman per (1/5)th week,

Hence, the mean is m = 1/5 for a woman arriving

and λ = 1/m = 5 = λ

we have to find the probability that it takes higher than a week for a high BP pregnant woman to arrive, i.e,

P(X>1) i.e. the probability that it takes more than a week for a high BP pregnant woman to show up,

Now,

P(X>1) = 1 - P(X<1),

Now, the probability density function is,

[tex]f(x) = \lambda e^{-\lambda x}[/tex]

And the cumulative distribution function (CDF) is,

[tex]CDF = 1 - e^{-\lambda x}[/tex]

Now, CDF gives the probability of an event occuring within a given time,

so, for 1 week, we have x = 1, and λ = 5, which gives,

P(X<1) = CDF,

so,

[tex]P(X < 1)=CDF = 1 - e^{-\lambda x}\\P(X < 1)=1-e^{-5(1)}\\P(X < 1)=1-e^{-5}\\P(X < 1) = 1 - 6.738*10^{-3}\\P(X < 1) = 0.9932\\And,\\P(X > 1) = 1 - 0.9932\\P(X > 1) = 6.8*10^{-3}\\P(X > 1) = 0.0068[/tex]

So, the probability that on a particular week, the hospital will receive on high BP pregnant woman is 0.0068

Perimeter = 52

Step-by-step explanation:

A tangent is a straight line that touches a circle at only one point.

The given diagram shows a circle with three points of tangency: S, T and U.

According to the Two-Tangent Theorem, if two tangents to a circle meet at one exterior point, the tangent segments are congruent.

The exterior points are P, Q and R. Therefore, the congruent segments are:

[tex]\overline{PS} = \overline{PT} = 9[/tex]

[tex]\overline{QT} = \overline{QU} = 4[/tex]

[tex]\overline{RS} = \overline{RU} = 13[/tex]

To find the value of x, use the equation PS = PT:

[tex]\overline{PS} = \overline{PT}[/tex]

 [tex]2x = 9[/tex]

  [tex]x = \dfrac{9}{2}=4.5[/tex]

To calculate the perimeter of triangle PQR, sum the tangent segments.

[tex]\begin{aligned}\textsf{Perimeter}&=\overline{PS}+\overline{PT}+\overline{QT}+\overline{QU}+\overline{RS}+\overline{RU}\\&=9+9+4+4+13+13\\&=52\end{aligned}[/tex]

Therefore, the perimeter of triangle PQR is 52 units.

The following sequences of transformations do not show congruency by mapping shape I onto shape II:

These sequences of transformations do not map shape I onto shape II because they either change the size or shape of the figure. The second sequence of transformations reflects shape I across the x-axis, rotates it 90° clockwise, and then translates it 4 units down.

This results in a figure that is flipped sideways and shifted down. The third sequence of transformations reflects shape I across the x-axis, rotates it 90° counterclockwise, and then translates it 6 units down. This results in a figure that is flipped upside down and shifted to the left.

To determine the type of correlation between two variables on a graph, we can examine the pattern or relationship exhibited by the data points.

If the data points on the graph form a roughly linear pattern with a positive slope, it indicates a positive correlation. This means that as one variable increases, the other variable also tends to increase.

Conversely, if the data points on the graph form a roughly linear pattern with a negative slope, it indicates a negative correlation. In this case, as one variable increases, the other variable tends to decrease.

Additionally, the strength of the correlation can be assessed by how closely the data points align with the overall trendline. If the points are tightly clustered around the trendline, it suggests a strong correlation, while scattered points indicate a weaker correlation.

By visually inspecting the graph and observing the direction and pattern of the data points in relation to the trendline, we can determine the type of correlation exhibited by the variables.

Therefore, Heather can make a maximum of 4 biscuits with the given ingredient quantities.

To determine how many biscuits Heather can make, we need to compare the amount of each ingredient required for a single biscuit to the total amount of ingredients she has.

Let's calculate the number of biscuits she can make based on the ingredient quantities provided:

First, we need to find the ratio of each ingredient required per biscuit:

Flour: 100g per biscuit

Butter: 120g per biscuit

Icing sugar: 80g per biscuit

Chocolate: 25g per biscuit

Next, we divide the total amount of each ingredient by the respective ratio to find the maximum number of biscuits she can make:

Flour: 2kg / 100g = 20 biscuits

Butter: 1kg / 120g = 8.33 biscuits (approximately)

Icing sugar: 340g / 80g = 4.25 biscuits (approximately)

Chocolate: 200g / 25g = 8 biscuits

Since we can only make a whole number of biscuits, the limiting factor is the icing sugar. Heather can only make 4 biscuits since she has 4.25 times the required amount of icing sugar.

1. Mr. John received more than 2 cords of wood based on the sizes of the stacked piles.

2. Based on the stacked piles, Mr. John received approximately 11,974 pieces of actual wood.

3. The cost per standard piece of wood is approximately $0.0417.

1. To determine if Mr. John received more or less than 2 cords of wood, we need to calculate the volume of each pile and compare it to the volume of a standard cord of wood.

Calculating the volume of each pile:

PILE #1:

Volume = 72 inches * 167 inches * 16 inches = 1,523,584 cubic inches

PILE #2:

Volume = 65 inches * 266 inches * 16 inches = 2,068,480 cubic inches

Calculating the volume of a standard cord of wood:

Volume of a standard cord = 4 feet * 4 feet * 8 feet = 128 cubic feet

Since 1 foot = 12 inches, the volume in cubic inches is 128 * 12 * 12 * 12 = 221,184 cubic inches.

Comparing the volumes:

Pile #1: 1,523,584 cubic inches

Pile #2: 2,068,480 cubic inches

Standard cord: 221,184 cubic inches

It is evident that both piles have significantly more volume than a standard cord of wood. Therefore, Mr. John received more than 2 cords of wood.

2. To determine the number of standard pieces of wood received, we need to calculate the number of pieces that can be obtained from the total volume of the piles.

Total volume of the piles = Volume of Pile #1 + Volume of Pile #2

Total volume = 1,523,584 cubic inches + 2,068,480 cubic inches = 3,592,064 cubic inches

Volume of a standard piece of wood = 5 inches * 5 inches * 12 inches = 300 cubic inches

Number of standard pieces of wood received = Total volume of the piles / Volume of a standard piece of wood

Number of pieces = 3,592,064 cubic inches / 300 cubic inches = 11,973.55 pieces (rounded to the nearest whole number)

Therefore, Mr. John received approximately 11,974 pieces of actual wood based on his stacked piles.

3. To calculate the cost per standard piece of wood, we need to divide the total cost of the two cords by the number of standard pieces received.

Total cost for both cords of wood = 2 cords * $250/cord = $500

Cost per standard piece of wood = Total cost / Number of standard pieces

Cost per piece = $500 / 11,974 = $0.0417 (rounded to four decimal places)

Therefore, the cost per standard piece of wood is approximately $0.0417.

Answer:

The area of this triangle is (1/2)(9)(8) = 36.

Answer:

To the nearest tenth, we have,

z = 19.9

Step-by-step explanation:

The missing side is the hypotenuse,

And we are given the side adjacent to the angle,

z = hupotenuse = H = ?

Adjacent = A = 15

Angle = α = 41

Since we have to find hypotenuse and we are given adjacent,

Using SOHCAHTOA,

We know the angle and adjcent but need to find Hypotenuse,

So, we use CAH

or,

cos(α) = A/H

cos(α) = 15/z

(since z = hypotenuse)

zcos(α) = A

z = A/(cos(α))

z = 15/cos(41)

z = 19.8752

If 20 tickets were purchased, there would be 22 entries in the raffle drawing.

Based on the information given in the table, we can see that the number of entries in the raffle drawing is always 2 more than the number of tickets purchased.

Let's represent the number of tickets purchased as x and the number of entries in the raffle drawing as y.

From the table, we can observe the relationship between x and y:

When x = 1, y = 3

When x = 2, y = 4

When x = 3, y = 5

When x = 4, y = 6

We can notice that for each value of x, y is always 2 more than x.

So, we can write the equation as y = x + 2.

To find the number of entries in the raffle drawing if 20 tickets were purchased, we substitute x = 20 into the equation:

y = x + 2

y = 20 + 2

y = 22

Therefore, if 20 tickets were purchased, there would be 22 entries in the raffle drawing.

The distance from F to G on walkway C is approximately 19.21 units.

To determine the distance from point F to point G on walkway C, we can use the information provided in the map and apply some basic geometric principles.

Looking at the map, we can see that walkway A and walkway B are parallel. Let's use this information to find the distance from F to G on walkway C.

First, let's identify the relevant points on the map. We have point F on walkway C and point G on walkway C. The map also shows two intersecting lines, representing walkways A and B, but we don't need to consider those for this particular calculation.

To find the distance from F to G on walkway C, we need to focus on the segment of walkway C that connects F and G. Based on the map, we can see that the segment of walkway C is perpendicular to both walkway A and walkway B.

Since walkway A and walkway B are parallel, and the segment of walkway C is perpendicular to both, we can conclude that the segment FG forms a right triangle with walkway A and walkway B.

In a right triangle, we can use the Pythagorean theorem to find the length of one side (FG) if we know the lengths of the other two sides.

Let's assume the length of the segment FG is represented by the variable 'd' (which we need to find).

From the map, we can see that the distance from F to walkway A is 15 units. Similarly, the distance from G to walkway B is 12 units.

Applying the Pythagorean theorem, we have:

d^2 = 15^2 + 12^2

d^2 = 225 + 144

d^2 = 369

Taking the square root of both sides, we find:

d ≈ √369

d ≈ 19.21

As a result, it takes 19.21 units to get from F to G on walkway C.

The decisions made by Mahmud Mahtab regarding stock dividend, stock split, and reverse stock split would result in the following changes to the accounts:

1) 10% Stock Dividend:

A stock dividend is a distribution of additional shares of stock to existing shareholders. In this case, a 10% stock dividend means that for every 10 shares held, shareholders will receive an additional share. As a result, the following changes would occur:

- Common stock: The number of shares would increase by 10% (3,000 additional shares).

- Additional paid-up capital: There would be no change.

- Retained earnings: There would be a reduction of the amount equal to the market value of the shares issued as dividends.

2) 2 for 1 Stock Split:

A stock split involves dividing existing shares into a larger number of shares. In a 2 for 1 stock split, each existing share would be split into two shares. The following changes would take place:

- Common stock: The number of shares would double (60,000 shares).

- Additional paid-up capital: There would be no change.

- Retained earnings: There would be no change.

3) 1 for 5 Reverse Stock Split:

A reverse stock split combines a number of existing shares into a smaller number of shares. In a 1 for 5 reverse stock split, every five shares would be consolidated into one share. The accounts would be affected as follows:

- Common stock: The number of shares would decrease by 80% (24,000 shares).

- Additional paid-up capital: There would be no change.
