The general common factor (GCF) of the polynomial equation [tex]24x^9 + 21x^6 = 0[/tex] is 3x6, which, after factoring, is the common factor of the coefficients and the terms enclosed in brackets.

We must factor out the common terms from both the coefficients and the exponents in order to determine the GCF (Greatest Common Factor) for the polynomial equation 24x9 + 21x6 = 0.

The first step is to determine the coefficients' common factor, which is 3. The equation can be changed to read:

3(8x^9 + 7x^6) = 0

We now need to determine which term the parenthesized terms have in common the most. Since x is raised to a power in both terms, we may factor out x^6 to obtain:

3x^6(8x^3 + 7) = 0

The greatest common factor of the polynomial equation 24x^9 + 21x^6 = 0 is 3x^6.

We can verify this by dividing both terms in the equation by 3x^6. Doing so gives us:

(8x^3 + 7) = 0

This equation has no common factors, and we cannot factor it further. Thus, the GCF of the original polynomial equation 24x^9 + 21x^6 = 0 is 3x^6

To graph the two lines, we can plot two points on each line and connect them with a straight line. For y = 3x + 2, we can choose x = 0 and x = 1 to get the points (0, 2) and (1, 5), respectively. For y = x - 2, we can choose x = 0 and x = 1 to get the points (0, -2) and (1, -1), respectively.

In the graph: The red line represents y=3x+2 and the blue line represents y=x-2

Explain the term straight line

A straight line is a geometric figure that extends infinitely in both directions and has no curvature or bends. It is the shortest distance between two points and can be described using various mathematical equations, such as y = mx + b, where m is the slope and b is the y-intercept. Straight lines are used in various fields, including geometry, physics, and engineering, to represent and analyze the relationships between objects or points.

According to the given information

To graph the system of equations y = 3x + 2 and y = x - 2, we can plot the two lines on the same coordinate plane and find the point where they intersect.

First, we can find the point of intersection by setting the two equations equal to each other:

3x + 2 = x - 2

Simplifying, we get:

2x = -4

x = -2

Substituting this value of x back into one of the equations, we get:

The rate at which her daily revenue is currently changing and the direction of the change is; Her revenue is currently increasing at $12 per day

The rate of change of a function is the rate at which the output of the function changes per unit change in the input of the function.

Let x represent the number of days, therefore;

The number of T-shirts Dorothy sells, y = 40 - 4·x

The price at which she sells the T-shirts = 7 + x

Therefore, Dorothy's daily revenue, R(x) = (40 - 4·x) × (7 + x) = 12·x - 4·x² + 280

The rate of change of her daily revenue can be obtained from the derivative of the revenue function as follows;

The rate at which her daily revenue is therefore;

R'(x) = d(R(x))/dx = 12 - 8·x

The rate at which her revenue is changing currently can be obtained from the rate function by plugging in x = 0, as follows;

R'(0) = 12 - 8×0 = 12

Answer:

We can use the Central Limit Theorem to solve this problem since we are dealing with a sample size greater than 30. The distribution of sample means will be approximately normal with a mean of 74 beats per minute and a standard deviation of 12.5 / sqrt(4) = 6.25 beats per minute.

To find the probability that the mean pulse rate of 4 adult females is between 70 and 78 beats per minute, we need to calculate the z-scores for both values and then use a z-table or calculator to find the area under the normal curve between those two z-scores.

The z-score for 70 beats per minute is:

z = (70 - 74) / 6.25 = -0.64

The z-score for 78 beats per minute is:

z = (78 - 74) / 6.25 = 0.64

Using a standard normal distribution table or calculator, the area between these two z-scores is approximately 0.4115.

Therefore, the probability that 4 adult females have pulse rates with a mean between 70 and 78 beats per minute is approximately 0.4115 or 41.15%.

Step-by-step explanation:

The resort should sell a number of 255 packages at a price of $2400 per person to maximize their monthly profit and the maximal profit is $613,400.

Maximal profit refers to the highest level of profit that a business or organization can achieve given certain constraints such as cost, demand, or pricing. It is the point at which a company or business generates the most revenue after accounting for all expenses associated with production and distribution of goods or services. To determine the maximal profit, a business will need to find the optimal balance between costs and revenue, while also taking into account factors such as competition and market demand. This involves analyzing a variety of financial metrics such as revenue, cost of goods sold, gross profit margin, and net profit margin, among others.

Let's begin by defining some variables:

P = price of the package

Q = number of packages sold

R = revenue

C = cost

Profit = revenue - cost

Based on the information given, we can create the following equations:

R = P * Q

C = 1600 + 2000 * Q

Profit = R - C = P * Q - (1600 + 2000 * Q)

We want to find the price that will maximize the monthly profit. To do this, we need to find an expression for profit in terms of P only. We can use the equation for C to substitute Q in the expression for profit:

C = 1600 + 2000 * Q

Q = (C - 1600) / 2000

Profit = P * Q - (1600 + 2000 * Q)

Profit =

Profit = P * ((C - 1600) / 2000) - C + 1600

Now we can find the derivative of profit with respect to P:

dProfit/dP = (C - 1600) / 2000

To find the value of P that maximizes profit, we need to set the derivative equal to 0:

dProfit/dP = 0

(C - 1600) / 2000 = 0

C = 1600

This means that profit is maximized when revenue equals cost, which makes sense. Substituting C = 1600 into the expression for profit, we get:

Profit = P * ((1600 + 2000 * Q - 1600) / 2000) - 1600

Profit = P * Q - 1600

Now we need to find the corresponding values of P and Q. We know that for every increase of $100 in price, there will be a decrease of 5 in the number of packages sold. This means that:

Q = 300 - (P - 2000) / 100 * 5

Substituting this into the expression for profit, we get:

Profit = P * (300 - (P - 2000) / 100 * 5) - 1600

To find the maximum profit, we can take the derivative of this expression with respect to P and set it equal to 0:

dProfit/dP = 300 - (P - 2000) / 20 = 0

P = 2400

This means that the price that will maximize the monthly profit is $2400 per person. To find the corresponding number of packages sold, we can substitute this into the equation for Q:

Q = 300 - (2400 - 2000) / 100 * 5 = 255

Therefore, the resort should sell 255 packages at $2400 per person to maximize their monthly profit. To find the maximal profit, we can substitute these values into the expression for profit:

Profit = 2400 * 255 - 1600 = $613,400.

If the job takes Reba 1 hours, the cost would be $ 19 with either artist

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let's assume the number of hours that Reba takes to paint the window is h. Then, the total cost of the job with Reba would be:

Total cost with Reba = $19 ( h )  + $41

The total cost with Pete is already given as a flat rate of $60.

We want to find the number of hours that Reba would have to take to charge the same amount as Pete, so we can set the two expressions for the total cost equal to each other and solve for "h":

$ 19 ( h ) + $ 41 = $ 60

Subtracting $41 from both sides, we get:

$ 19 ( h ) = $ 19

Dividing both sides by $ 19, we get:

h = 1

So Reba would have to take 1 hour to charge the same amount as Pete.

To calculate the cost of the job with either artist if it takes Reba 1 hour, we can substitute h=1 into the expression for the total cost with Reba:

Total cost with Reba = $ 19 ( 1 ) + $ 41 = $ 60

Hence , this is the same as the flat rate quoted by Pete, so the cost of the job would be $60 with either artist if it takes Reba 1 hour

Therefore, the lawnmower can cut grass for 2.5 hours on 5/6 of a gallon of fuel in the gas can

To find out how long the lawnmower can cut grass with 5/6 of a gallon of gas, we first need to figure out how many gallons of gas the lawnmower will use per hour:

1 hour of grass cutting = 1/3 gallon of gas

1 gallon of gas = 3 hours of grass cutting

So the lawnmower uses 1/3 gallon of gas per hour, which means that 1 gallon of gas will last for 3 hours of grass cutting.

Now we can use this conversion factor to figure out how long 5/6 of a gallon of gas will last:

5/6 gallon of gas * 3 hours of grass cutting per 1 gallon of gas = 15/18 hours of grass cutting

Simplifying this fraction by dividing the numerator and denominator by 3:

15/18=3/6

So 5/6 of a gallon of gas will last for 5/6 of 3 hours, which is equal to 2.5 hours of grass cutting.

As a result, 5/6 of a gallon of gas will last for 5/6 of 3 hours, or 2.5 hours of mowing the lawn.

The required value of impulse is 88 N-s and the mass of the cart is 8.8 kg.

Newton's Second Law relates an object's acceleration as a function of both the object's mass and the applied net force on the object.

Given data:

The speed of cart is, v = 10 m/s.

We are given the Force-time graph for which the area of the force-time graph will provide the value of impulse. So from the graph, the maximum force is,

F = 22 N

And time interval is,

t = 4.5 s - 0.5 s

t = 4 s

So, the impulse is,

I = Area of graph

I = F × t

I = 22 × 4

I = 88 N-s

Now the standard expression for the impulse as per the impulse-momentum theorem is,

I = ΔP (Change in momentum)

I = m ×( v - u )

Here, u is the final velocity, and since the cart stops finally, then u = 0 m/s. And m is the mass of the cart.

Solving as,

88 = m ×( v - u )

88 = m ×( 10 - 0 )

m = 8.8 kg

Thus, we can conclude that the required value of impulse is 88 N-s and the mass of car is of 8.8 kg.

In algebra, the definition of an equation in its simplest form is a mathematical statement that shows that two mathematical expressions are equal. For example, 3x 5 = 14 is an equation where 3x 5 and 14 are two expressions separated by an equal sign.

Let's say plan A takes x hours and plan B takes y hours.

Based on the given data, we can create two equations:

Monday: 6x + 5y = 7

Tuesday: 2x + 3y = 3

We can solve this system of equations by elimination or substitution.

Eliminating, we can multiply the second equation by two and subtract it from the first equation:

(6x + 5 y) - 2 (2x + 3y) = 7 - 2 (3)

Simplifying this, we get:

2x - y = 1

Using substitution, we can solve an equation in one variable and replace it with another equation:

From the first equation we can solve for x:  

6x + 5y = 7

6x = 7-5 years

x = (7-5 ​​years) / 6

Substituting this into the second equation, we get:

2 ((7-5 years) / 6) + 3 y = 3

Simplifying this, we get:

7 y = 9

y = 9/7

Now that we know y, we can substitute it back into both equations to solve for x:

6 x + 5 (9/7) = 7

Simplifying this, we get:

A)By applying permutation and combination we can select committee in  1782 ways.

B) The probability cannot be determined with the given information, as the calculated probability is greater than 1, which is not possible.

Permutation and combination are two concepts in mathematics that deal with counting the number of possible outcomes or arrangements in a given situation. Permutation refers to the arrangement of objects in a specific order, while combination refers to the selection of objects without regard to the order in which they are chosen.

Probability is a measure of the likelihood or chance that an event will occur. It is a number between 0 and 1.

According to the given information:

A) To find the number of ways to select a committee of 5 members, where exactly one of Mr Lan and Mrs Lan must be on the committee, we can use the principle of inclusion-exclusion i.e. Permutation and combination:

First, we find the total number of ways to select a committee of 5 members from 14 members (6 men and 8 women), which is given by:

C(14,5) = 2002

Next, we find the number of ways to select a committee of 5 members that includes both Mr Lan and Mrs Lan, which is given by:

C(12,3) = 220

Note that we choose 3 members from the remaining 12 members after Mr and Mrs Lan have been chosen.

Finally, we subtract the number of committees that include both Mr Lan and Mrs Lan from the total number of committees, since we only want committees that include exactly one of them:

2002 - 220 = 1782

Therefore, there are 1782 different ways to select a committee of 5 members where exactly one of Mr Lan and Mrs Lan must be on the committee.

B) To find the probability that there are more women than men on the committee, given that Mrs Lan was selected, we need to consider the number of committees that satisfy this condition and divide by the total number of committees that include Mrs Lan.

If Mrs Lan is selected, there are two cases to consider:

Case 1: The committee has more women than men.

In this case, we need to select 4 members from the 8 women and 1 member from the 5 men, which can be done in C(8,4) x C(5,1) = 560 ways.

Case 2: The committee has an equal number or more men than women.

In this case, we need to select 3 members from the 8 women and 2 members from the 5 men, which can be done in C(8,3) x C(5,2) = 560 ways.

Therefore, the total number of committees that include Mrs Lan and have more women than men or an equal number of women and men is 560 + 560 = 1120.

The total number of committees that include Mrs Lan is C(13,4) = 715, since we choose 4 members from the remaining 13 members after Mrs Lan has been chosen.

Therefore, the probability of selecting a committee with more women than men or an equal number of women and men, given that Mrs Lan was selected, is:

1120/715 = 1.5664

Note that this probability is greater than 1, which is not possible. Therefore, there is an error in the calculation, and the correct probability cannot be determined with the given information.
