The number of Grade 6 students were asked in total is 100 students.

Let the number of students who choose Natural History be x.

Since the number of students who chose the Museum of Math was 50 more than the number of students who chose the Museum of Natural History. This will be x + 50

The ratio of students who chose the Museum of Math to students who chose the Museum of Natural History was 3 to 1. The expression will be illustrated thus:

1/3 = x/x+50

Cross multiply

3x = x + 50

Collect like terms

3x - x = 50.

2x = 50

Divide

x = 50/2

x = 25

Also, x + 50 = 25 + 50 = 75

The number of Grade 6 students that were asked will be:

= 25 + 75

= 100

The value of the average life (t_average) of unstable nuclei in terms of the decay constant (λ) is given by ln(2)^2 / λ.

To derive the value of the average life (t_average) of unstable nuclei in terms of the decay constant (λ), we can start by defining the average life.

The average life (t_average) of unstable nuclei represents the average time it takes for half of the original sample of nuclei to decay. It is closely related to the concept of the half-life of a radioactive substance.

Let's denote N(t) as the number of nuclei remaining at time t, and N₀ as the initial number of nuclei at time t = 0.

The decay of unstable nuclei can be described by the differential equation:

dN(t)/dt = -λN(t)

This equation states that the rate of change of the number of nuclei with respect to time is proportional to the number of nuclei present, with a proportionality constant of -λ (the negative sign indicates decay).

Solving this differential equation gives us the solution:

N(t) = N₀ * e^(-λt)

Now, let's find the time t_half at which half of the original nuclei have decayed. At t = t_half, N(t_half) = N₀/2:

N₀/2 = N₀ * e^(-λt_half)

Dividing both sides by N₀ and taking the natural logarithm:

1/2 = e^(-λt_half)

Taking the natural logarithm of both sides:

ln(1/2) = -λt_half

Using the property of logarithms, ln(1/2) = -ln(2):

ln(2) = λt_half

Now, we can solve for t_half:

t_half = ln(2) / λ

The average life (t_average) is defined as the average time it takes for half of the nuclei to decay. Since we are considering an exponential decay process, the average life is related to the half-life by a factor of ln(2):

t_average = t_half * ln(2)

Substituting the expression for t_half, we have:

t_average = (ln(2) / λ) * ln(2)

Simplifying further:

t_average = ln(2)^2 / λ

Therefore, the value of the average life (t_average) of unstable nuclei in terms of the decay constant (λ) is given by ln(2)^2 / λ.

The graph has an asymptote at y = 0.

Option (A) is correct.

What is the asymptote of the graph?

An asymptote is a straight line that constantly approaches a given curve but does not meet at an infinite distance. In other words, an Asymptote is a line that a curve approaches as it moves toward infinity.

The given function is:

                                \(y = 12.(\frac{1}{2})^x\)

Now let's draw the graph for this given function,

By observing the graph we can conclude that the graph has an asymptote at y = 0 cause it is not meeting to the x-axis when it is approaching infinity.

Hence, the graph has an asymptote at y = 0.

The given information about the school play involves two individuals, Rico and Sasha, purchasing adult and child tickets. The situation can be represented by a system of linear equations in terms of the cost of an adult ticket (x) and the cost of a child ticket (y).

Let's set up the system of linear equations based on the given information:
Equation 1: 3x + 5y = 50 (for Rico's ticket purchases)
Equation 2: x + 5y = 31 (for Sasha's ticket purchases)
To solve the system, we can use various methods, such as substitution or elimination. Let's solve it using the elimination method:
Multiplying Equation 2 by 3, we get:
3(x + 5y) = 3(31)
3x + 15y = 93
Now we have the system of equations:
3x + 5y = 50
3x + 15y = 93
By subtracting Equation 1 from Equation 2, we eliminate the x term:
(3x + 15y) - (3x + 5y) = 93 - 50
10y = 43
y = 4.3
Substituting the value of y into Equation 1:
3x + 5(4.3) = 50
3x + 21.5 = 50
3x = 50 - 21.5
3x = 28.5
x = 9.5
Therefore, the cost of an adult ticket (x) is $9.5, and the cost of a child ticket (y) is $4.3 in this scenario.

Answer:

3\(\sqrt{13}\)

Step-by-step explanation:

Calculate the distance using the distance formula

d = \(\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }\)

with (x₁, y₁ ) = (- 9, 8) and (x₂, y₂ ) = (- 3, - 1)

d = \(\sqrt{(-3-(-9))^2+(-1-8)^2}\)

  = \(\sqrt{(-3+9)^2+(-9)^2}\)

  = \(\sqrt{6^2+81}\)

   = \(\sqrt{36+81}\)

   = \(\sqrt{117}\)

   = \(\sqrt{9(13)}\)

To determine the y-coordinate of the third listener, we need to use the concept of wavefronts and the geometry of the problem.

Since the wavefront reaches the first two listeners simultaneously, we can conclude that they are equidistant from the source. Let's call this distance d.

The distance from the source to the first listener is given as x = -8 m, and the distance from the source to the second listener is x = 2.0 m.

Using the concept of equidistant points, we can set up the following equation:

√(d^2 + (-8)^2) = √(d^2 + (2.0)^2)

Squaring both sides of the equation, we get:

d^2 + 64 = d^2 + 4

Simplifying the equation, we have:

60 = 0

This equation is not possible and implies that there is no solution that satisfies the given conditions. Therefore, the y-coordinate of the third listener cannot be determined based on the information provided.

(f + g)(6) = 39 represents the total number of animals adopted by both shelters in 6 months, based on the combined adoption rates of the two shelters.

Part A:

To find (f + g)(x), we add the functions f(x) and g(x):

(f + g)(x) = f(x) + g(x)

= (3x + 10) + (x + 5) (substitute the given functions)

= 4x + 15 (combine like terms)

Therefore, (f + g)(x) = 4x + 15.

Part B:

To evaluate (f + g)(6), we substitute x = 6 into the (f + g)(x) function:

(f + g)(6) = 4(6) + 15

= 24 + 15

= 39

Therefore, (f + g)(6) = 39.

Part C:

The value of (f + g)(6) represents the combined number of animals adopted by both shelters after 6 months. The function (f + g)(x) gives us the total adoption rate of the two shelters at any given time x. When x = 6, the combined adoption rate was 39 animals.

The required solution will be -30 which is expressed as an integer.

To represent this in a general context, we may utilize functions that are referred to in terms of the number tossed.

We know that if the number he gets is an even number, he will get 5 times the number.

As a result, the function for when the integer x is even is f(x) = 5x.

If the number is an odd number, he will lose 10 times the number.

As a result, the function for when the integer x is odd is f(x)=-10x.

Finally, Joe tosses a 3, which is an odd integer, hence the function we will represent is f(x) = - 10x.

⇒ f(3) = -10(3) = -30

The example of real life problems:
1. Real-life example: Using a function to calculate taxi fare based on distance traveled.

2. Helping a friend: Guiding them through examples and providing explanations and resources for solving operations on functions.

The explanation for the above

1. In a real-life scenario, functions can be used to solve practical problems. For example, when calculating the cost of a taxi ride, a function can be defined where the input (distance traveled) is multiplied by the cost per kilometer.

By plugging in the distance value into the function, the output will provide the total cost of the ride. This allows for a systematic and consistent way to determine the fare based on distance.

2. When helping a friend solve operations on functions, it's important to ensure they have a solid understanding of the fundamental concepts of functions.

Once that foundation is established, guiding them through examples is crucial. By explaining each step involved in performing operations on functions, such as addition, subtraction, multiplication, and composition, the friend can gain clarity and build confidence in their ability to solve function-related problems.

Answer:

\(7+(11-4\times 2)=10\)

Step-by-step explanation:

So, this question involves you to play around with the numbers and the operations a bit. I've come up with a solution, but perhaps there are others as well.

So, we have:

\(7\text{ } 11\text{ } 4\text{ } 2\text{ } =\text{ } 10\)

So, what we can do is, for instance, multiply 4 and 2. Subtract that into 11. And then add the difference to 7. Thus:

\(7+(11-4\times 2)=10\)

This is a true number sentence. Let's do it to make sure.

First, do the operations inside the parentheses.

Multiplication comes first, so multiply:

\(7+(11-8)=10\)

Again, do the parentheses first. Subtract:

\(7+(3)=10\)

Now add:

\(10=10\)

Answer:

12 sales

Let x represent the number of sales each man had.

For Salesman A, he earns $65 per sale; this is 65x.

For Salesman B, he earns $40 per sale; this is 40x.  We also add to this his weekly salary of $300; this gives us 40x+300.

Since their pay was equal, set the two expressions equal:

65x = 40x+300

Subtract 40x from each side:

65x-40x = 40x+300-40x

25x = 300

Divide both sides by 25:

25x/25 = 300/25
