we have

15!12!(4−1)!

15!12!(3!)=3,758,268,687,305,932,800,000

therefore

the answer is

The \(x^{th}\) number in the sequence will be   \(F[x]=\dfrac{5}{2} F[x]\)

The given function is

\(F[x]=\dfrac{3}{2} \times \dfrac{5}{2}^{x-1}\)

Now at  \(x=x+1\) for the function

\(F[x+1]=\dfrac{3}{2} \times \dfrac{5}{2}^{x+1-1}\)

\(F[x+1]=\dfrac{3}{2} \times \dfrac{5}{2}^{x }\)

Now we can write

\(F[x+1]=\dfrac{3}{2} \times \dfrac{5}{2}^{x-1} \dfrac{5}{2}^1\)

Since     \(F[x]=\dfrac{3}{2} \times \dfrac{5}{2}^{x-1}\)

so

\(F[x]=\dfrac{5}{2} F[x]\)

Thus the \(x^{th}\) number in the sequence will be   \(F[x]=\dfrac{5}{2} F[x]\)

Answer:

Let total students be ‘X’

No of girls = (X-20)

Girls/Boys=7/5=(X-20)/20

7(20) =5(X-20)

140=5X-100

5X=240

X = 240/5

X =48

So, Total Students are 48

No of girls = (X-20) = 48-20 = 28

The exact solutions for the equation tan(θ) = -1 in the interval 0≤θ≤2π are θ = (3π)/4 and θ = (7π)/4.

To find all exact solutions on the interval 0≤θ≤2π for the equation tan(θ) = -1, follow these steps:

Step 1: Identify the principal angles where tan(θ) = -1.
The tangent function is negative in the second and fourth quadrants.

Recall that tan(θ) = sin(θ) / cos(θ). In the second quadrant, sin(θ) is positive and cos(θ) is negative. In the fourth quadrant, sin(θ) is negative and cos(θ) is positive.

The principal angles where tan(θ) = -1 are θ = (3π)/4 and θ = (7π)/4, as these angles have equal magnitude for sin(θ) and cos(θ) but opposite signs.

Step 2: Check if the principal angles are within the given interval.
Both (3π)/4 and (7π)/4 lie within the interval 0≤θ≤2π.

Step 3: List the exact solutions.
The exact solutions for the equation tan(θ) = -1 in the interval 0≤θ≤2π are θ = (3π)/4 and θ = (7π)/4.

The input and the output of a function are key components in understanding how a function operates. The input refers to the value or values that are given to the function as an argument, while the output refers to the result or results that the function returns after processing the input.

In other words, the input is what you provide to the function, and the output is what you get in return. The input can be a single value or a set of values, depending on the requirements of the function. The output can also be a single value or a collection of values, again depending on the function's purpose.

It's important to note that the input and output of a function are not always the same. The function may perform calculations or transformations on the input, and the output may be different from the input. This transformation is what gives functions their ability to perform specific tasks and solve problems.

In summary, the input is what you give to a function, and the output is what you get in return after the function processes the input.

Step-by-step explanation:

Answer:

Convergent

Step-by-step explanation:

One method to determine if  \(\displaystyle \sum^\infty_{k=1}ke^{-k^2}\)is convergent or divergent is the Integral Test.

Suppose that the function we use is \(f(x)=xe^{-x^2}\). Over the interval \([1,\infty)\), the function is always positive and continuous, but we also need to make sure it is decreasing before we can proceed with the Integral Test.

The derivative of this function is \(f'(x) = e^{-x^2}(1-2x^2)\), so our critical points will be \(\displaystyle x=\pm\frac{1}{\sqrt{2}}\), but we can drop the negative critical point as we are starting at \(k=1\). Using some test points, we can see that the function increases on the interval \(\bigr[0,\frac{1}{\sqrt{2}}\bigr]\) and decreases on the interval \(\bigr[\frac{1}{\sqrt{2}},\infty\bigr)\). Since the function will eventually decrease, we can go ahead with the Integral Test:

\(\displaystyle \int_{{\,1}}^{{\,\infty }}{{x{{{e}}^{ - {x^2}}}\,dx}} & = \mathop {\lim }\limits_{t \to \infty } \int_{{\,1}}^{{\,t}}{{x{{{e}}^{ - {x^2}}}\,dx}}\hspace{0.5in}u = - {x^2}\\ & = \mathop {\lim }\limits_{t \to \infty } \left. {\left( { - \frac{1}{2}{{{e}}^{ - {x^2}}}} \right)} \right|_1^t\\ & = \mathop {\lim }\limits_{t \to \infty } \left( {-\frac{1}{2}{{e}}^{ - {t^2}}-\biggr(-\frac{1}{2e}\biggr)}} \right) = \frac{1}{2e}\)

Therefore, since the integral is convergent, the series must also be convergent by the Integral Test.

The value of x is 3.

Given that,

If  \(5 + 20 \times 2^{2-3x}\),

And Baseline = \(10 \times 2^{-2x}+5\)

We have to find,

The value of x?

According to the question,

To determine the value of x in the equation following all the steps given below.

Equation; \(\rm 5 + 20 \times 2^{2-3x} = 10 \times 2^{-2x}+5\)

                   \(\rm5- 5 + 20 \times 2^{2-3x} = 10 \times 2^{-2x}+5-5\\\\\rm 20 \times 2^{2-3x} = 10 \times 2^{-2x}\)

                    \(\rm 20 \times 2^{2-3x} = 10 \times 2^{-2x}\\\\\dfrac{ 20 \times 2^{2-3x} }{10}= \dfrac{10 \times 2^{-2x}}{10}\\\\\rm 2 \times 2^{2-3x} = 2^{-2x}\)

                   \(\rm 2 \times 2^{2-3x} = 2^{-2x}\\\\2^1 \times 2^{2-3x} = 2^{-2x}\\\\2^{2-3x+1} = 2^{-2x}\\\\\)

                    \(\rm 2-3x+1 = -2x\\\\-3x+2x = -1-2\\\\-x = -3\\\\x=3\)

Hence, The required value of x is 3.

In the second step of solving the inequality 5x - 9 < 91, the property used is the addition property of inequalities.

This property states that adding the same value to both sides of an inequality does not change the inequality's direction. By adding 9 to both sides of the inequality, we aim to isolate the variable term. The inequality becomes 5x < 100.

The addition property allows us to perform this operation and maintain the validity of the inequality. It is a fundamental property in solving inequalities, enabling us to simplify and manipulate expressions.
