Answer:

There are 18 total pieces of vegetables, so there are 18 possible choices for the first piece, 17 possible choices for the second piece, 16 possible choices for the third piece, and so on, until there is only 1 possible choice for the last piece. Therefore, the total number of different orders we could eat all the vegetables is:

18 x 17 x 16 x 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

which simplifies to:

18! / 0! = 6,402,373,705,728

Therefore, there are 6,402,373,705,728 different orders in which we could eat all the vegetables.

Answer:

There are 6,402,373,705,728 different orders in which we could eat all the vegetables.

Step-by-step explanation:

To find the total number of different orders in which we could eat all the vegetables, we can use the formula for permutations of n objects:

[tex]\sf\qquad\dashrightarrow P(n) = n![/tex]

where:

In this case, we have a total of 18 vegetables (6 carrot sticks + 4 celery sticks + 5 tomatoes + 3 pieces of cauliflower). So we can calculate the permutation of 18 objects:

[tex]\begin{aligned}\sf:\implies P(18)& =\sf 18! \\&=\sf 18 \times 17 \times 16 \times ... \times 3 \times 2 \times 1 \\ &= \boxed{\bold{\:\:6,402,373,705,728\:\:}}\:\:\:\green{\checkmark}\end{aligned}[/tex]

Therefore, there are 6,402,373,705,728 different orders in which we could eat all the vegetables.

The rate at which the infected population is growing after 8 days of the outbreak is approximately 1096.57 people per day, as determined by the derivative of the given function with respect to time.

To find the rate at which the infected population is growing after 8 days, we need to take the derivative of the given function I(t) with respect to t:

[tex]dI/dt = 3900(0.0514)e^(0.0514t)[/tex]

At t=8, the rate at which the infected population is growing is:

[tex]dI/dt = 3900(0.0514)e^(0.0514*8) = 1096.57[/tex]

Therefore, the rate at which the infected population is growing after 8 days is approximately 1096.57 people per day.

It is important to note that this rate of growth is an instantaneous rate at t=8, and it will likely change as time passes and the outbreak progresses. Furthermore, the rate of growth of the infected population depends on various factors such as the transmission rate of the virus, the effectiveness of preventive measures, and the availability of healthcare resources.

In conclusion, the rate at which the infected population is growing after 8 days of the outbreak is approximately 1096.57 people per day, as determined by the derivative of the given function with respect to time. This result provides insight into the early stages of a flu outbreak, but further analysis is required to understand the longer-term dynamics of the outbreak and the factors that affect the spread of the disease.

Answer:

-84+(-11)= -95

-84 + (-11) = -84 - 11 = -95

By the commutative property, adding a negative number is the same as subtracting that number as a positive; therefore, something + (-11) = something - 11. After changing the equation from -84 + (-11) to -84 - 11, we use regular addition properties, adding the tens place and ones place to get -95.

The inequality states that the sum of the number of conference rooms and ballrooms should be greater than the number of guests, so that all the guests can be accommodated. The correct answer is d. 30y + 139x>1640.

It is usually written using symbols such as “<”, “>”, “≤”, and “≥”, where one side of the expression is greater than, less than, or equal to the other side.

This is the appropriate inequality to determine how many of each type of room Amy will need to reserve because it expresses the total number of guests (1,640) that must be accounted for in the total number of conference rooms (30y) and ballrooms (139x).

To solve the inequality, Amy can start by assuming the number of conference rooms (y) she will need to reserve.

If she decides to reserve 10 conference rooms, the inequality will become 30(10) + 139x > 1640.

This can be simplified to 1390x > 1640 - 300, which reduces to x > 7.64. This means that Amy will need to reserve at least 8 ballrooms to accommodate all 1,640 guests.

We have 24 possible permutations because there are four choices for the first place, three choices for the second place (as two people have already won first and second place), and two choices for the third place (as three people have already won first, second, and third place).

For the 100 m race with Mark Chase and Beatrice, the sample space of all the possible ways in which the three runners can win first, second, and third place is:

{M-C-B, M-B-C, C-M-B, C-B-M, B-M-C, B-C-M}

where M stands for Mark, C stands for Chase, and B stands for Beatrice. We have six possible permutations because there are three choices for the first place, two choices for the second place (as one person has already won first place), and one choice left for the third place.

If there were four runners and three positions to be won, the sample space would be:

{A-B-C-D, A-B-D-C, A-C-B-D, A-C-D-B, A-D-B-C, A-D-C-B, B-A-C-D, B-A-D-C, B-C-A-D, B-C-D-A, B-D-A-C, B-D-C-A, C-A-B-D, C-A-D-B, C-B-A-D, C-B-D-A, C-D-A-B, C-D-B-A, D-A-B-C, D-A-C-B, D-B-A-C, D-B-C-A, D-C-A-B, D-C-B-A}

Rewriting each explicit formula in function form given below:

[tex]g(n) = -3 * (1/2)^(^n^-^1^)[/tex]

[tex]f(n) = 4 * (1/3)^(^n^-^1^)[/tex]

To convert an explicit formula into a function form, one must denote the variable 'n' as its respective input and represent the formula with that of a function.

Listed below are the steps required:

Original formulas:

[tex]g n = -3.(1_2)n- 1g[/tex]

[tex]n = 4.(1_3)n-1[/tex]

In order to transform the original expression to function format, follow these instructions for each individual formula:

- Step 1: Establish both the name of the function and the input parameter it accepts, denoted respectively by 'g', or 'n'.

- Step 2: Alter the specified representation; replace "g n" with "g(n)".

- Step 3: Substitute the hyphen sign '_' with a division symbol '/'.

Subsequently, applying this method specifically on equation g n = -3 * (1_2)n - 1g generates:

[tex]g(n) = -3 * (1/2)^(^n^-^1^)[/tex]

Thus, the rewritten version in function format is displayed as priorly referred:

[tex]g(n) = -3 * (1/2)^(^n^-^1^)[/tex]

To implement the same procedure on another given formula, where it states n = 4 * (1_3)n - 1:

- Step 1: Uncover the variables' identity with regards to the name of the function and the current parameters utilized, therefore establishing a new function label 'f' while preserving the relative input, just like previously conducted during the initial steps.  

- Step 2: Adapt your notation appropriately utilizing the newly established variables mentioned in Step 1.

- Step 3: Substitute the underscore designation '*' present within the term with a forward slash '/'.

As a result, following the process will create the convenient formulation of the certain algebraic formula as f(n) = [tex]4 * (1/3)^(^n^-^1^).[/tex]

Thus, the final draft written in functional form is presented as:

[tex]f(n) = 4 * (1/3)^(^n^-^1^)[/tex]

What is right angle triangle?

The term "right-angled triangle" refers to any triangle with an internal angle that is either a right angle or 90 degrees in value. The right triangle or the 90-degree triangle are other names for this triangle because of this. Right triangles have "opposite" and "adjacent" sides, which refer to the sides that are across from and next to respective angles, respectively. When a right triangle is formed, the hypotenuse is its longest side.

We can consider the flagpole, the ground, and the rope as forming a right triangle. The angle between the flagpole and the rope is 90 degrees, and the angle between the rope and the ground is 35 degrees. Therefore, the angle between the flagpole and the ground is 90 - 35 = 55 degrees.

Let's call the length of the rope "r". We can use the trigonometric function tangent to find r:

tan(35°) = opposite/adjacent = r/20

Multiplying both sides by 20, we get:

r = 20 tan(35°)

Using a calculator, we get:

r ≈ 11.9 feet

Therefore, the length of the rope is approximately 11.9 feet.

Step-by-step explanation:

If all the sides of the room are equal, all you have to do is 20*20 = area

The Results:

a) Cost of the bouncy castle for 20 children = £149

b) Number of children who went to the party = 14.

a) To find the cost of the bouncy castle for 20 children, we can substitute the number of children, which is 20, into the formula provided:

Cost = £3.65 * number of children + £76

Cost = £3.65 * 20 + £76

Now we can estimate the cost:

Cost = £73 + £76

Cost = £149

Thus, the cost of the bouncy castle for 20 children = £149.

b) To find the number of children who went to the party based on the given cost of £127.10, we can rearrange the formula to solve for the number of children:

Cost = £3.65 * number of children + £76

£127.10 = £3.65 * number of children + £76

Subtracting £76 from both sides of the equation:

£127.10 - £76 = £3.65 * number of children

£51.10 = £3.65 * number of children

Now we can divide both sides of the equation by £3.65 to isolate the variable:

£51.10 / £3.65 = number of children

14 = number of children

Therefore, the number of children who went to the party = 14.

To cover the full football pitch, you will want 10 bags of fertiliser, rounded up to the nearest whole number.

The term "area" refers to the volume of space occupied by a two-dimensional (2D) form or surface.

It's represented by squares.

You must multiply the length by the breadth of the football pitch to determine its total area:

field size for football = length x width

field size for football = 360 feet x 160 feet

field size for football = 57,600 square feet

You must now calculate how many thousands of square feet the football pitch has in order to get the total amount of fertiliser required:

the size of a football pitch in square feet = the size of the football pitch overall / 1,000

the size of a football pitch in square feet = 57,600 / 1,000

the size of a football pitch in square feet = 57.6

You must spread 8 pounds of fertiliser per 1,000 square feet of the football pitch because it is 57.6 thousand square feet in size.

Total required fertiliser quantity = 8 pounds per 1,000 square feet x 57.6 thousand square feet

Total required fertiliser quantity = 460.8 pounds

Given that the fertiliser is sold in 50-pound bags, you will require:

number of fertiliser bags = Total amount of fertilizer needed / Weight of each bag
