The area of the sector with a central angle of 60 degree and radius of 8 units is approximately 33.5 sqaure units.

A sector of a circle is simply part of a circle made up of an arc and two radii.

The area of a sector of a circle can be expressed as:

Area = (θ/360º) × πr²

Where θ is the sector angle in degrees, and r is the radius of the circle.

From the image:

Measure of central angle θ = 60 degrees

Radius r = 8 units

Plug these values into the above formula and solve for the area:

Area = (θ/360º) × πr²

Area = (60°/360°) × π × 8²

Area = 1/6 × π × 64

Area = 1/6 × π × 64

Area = 33.5 sqaure units.

Therefore, the area is approximately 33.5 sqaure units.

We are required to determine which is a geometric sequence.

Firstly, let us look at what a Geometric sequence is .

In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

In summary, a Geometric sequence has a common ratio.

Let us take a look at the options one after the other

A. -5,0,10,25,45

B. 1,2,4,8,16

C.-3,1,5,9

D. 4,8,24,96,480

Answer:

number is 4

Step-by-step explanation:

let n be the number then twice the number is 2n and the difference of the number and 3 is n - 3 , so

2n + 3(n - 3) = 11 ← distribute parenthesis and simplify left side

2n + 3n - 9 = 11

5n - 9 = 11 ( add 9 to both sides )

5n = 20 ( divide both sides by 5 )

n = 4

As a check

twice the number is 2 × 4 = 8

increased by 3 times the difference of n and 3 is

8 + 3(4 - 3) = 8 + 3(1) = 8 + 3 = 11 ← Correct

Answer: B; (-6,6)

Step-by-step explanation: Since the line is perpendicular that means that the slope is the negative reciprocal of the other. Since the line that is perpendicular to the non-drawn out line has a slope of -1, that means that the line that isn't drawn has a slope of negative one. This means that for every decrease in x, there will be the same decrease in y. Therefore, if we went four down from x, we would also go 4 down from y which means that the correct answer would be B.

Answer:

3. 12

4. 10.63

Step-by-step explanation:

3. a^2 + b^2 = c^2

a^2 + 5^2 = 13^2

a^2 = 169 - 25

a^2 = 144

a = √144 = 12

4. a^2 + b^2 = c^2

c^2 = 7^2 + 8^2

c^2 = 49 + 64

c^2 = 113

c = √113 = 10.63

Answer:

1296 meters

Step-by-step explanation:

I assume we use the free fall equation \(s=16t^2\)

After 9 seconds:

\(s=16t^2\)

\(s=16(9)^2\)

\(s=16(81)\)

\(s=1296\)

This means that the height of the building is 1296 meters

Given that \(\(T(n)\) = \(10n^2-3n\)\) if (\(\(n=1\)\)), you have to prove it by induction. So, we have proved it by induction that  \($$\(T(n)=10n^2-3n\)$$\)  if ( n= 1). The given statement is true for all positive integers n

Let's do it below: The base case (n=1) is given as follows: \(T(1)\) =\(10\cdot 1^2-3\cdot 1\\&\)=\(7\end{aligned}$$\). This implies that \(\(T(1)\)\) holds true for the base case.

Now, let's assume that \(\(T(k)=10k^2-3k\)\) holds true for some arbitrary \(\(k\geq 1\).\)

Thus, for n=k+1, T(k+1) = \(10(k+1)^2-3(k+1)\\&\) = \(10(k^2+2k+1)-3k-3\\&\)=\(10k^2+20k+7k+7\\&\) = \(10k^2-3k+20k+7k+7\\&\) = \(T(k)+23k+7\\&\) = \((10k^2-3k)+23k+7\\&\) =  \(10(k+1)^2-3(k+1)\).

Therefore, we have proved that the statement holds true for n=k+1 as well. Hence, we have proved it by induction that  \($$\(T(n)=10n^2-3n\)$$\)  if (n=1). Therefore, the given statement is true for all positive integers n.

To earn a profit of $10, we need to buy and sell 10 dollars.

The difference between the buying and selling rates is the profit margin for the currency exchange. Here, the profit margin is 116.5 - 115.25 = 1.25 Rs per dollar.

To make a profit of $10, we need to buy and sell enough dollars to earn a profit of 1.25*10 = 12.5 Rs.

Let's assume we buy and sell x dollars. Then the cost of buying x dollars is 115.25x Rs, and the revenue from selling x dollars is 116.5x Rs.

So, the profit from buying and selling x dollars is (116.5x - 115.25x) = 1.25x Rs.

We need to find x such that 1.25x = 12.5, which gives x = 10.

Therefore, we need to buy and sell 10 dollars to earn a profit of $10.

If the alternative hypothesis is that the proportion of items in population 1 is larger than the proportion of items in population 2, then the null hypothesis should be that there is no significant difference in the proportion of items between population 1 and population 2.

Based on the information provided, the null hypothesis should be:

The null hypothesis is that the proportion of items in population 1 is less than or equal to the proportion of items in population 2.

This is denoted as H₀: P₁ ≤ P₂. The alternative hypothesis, as you mentioned, is that the proportion of items in population 1 is larger than the proportion of items in population 2, which is represented as H₁: P₁ > P₂.

Answer:

Step-by-step explanation:

a) δ(f) represents the Dirac delta function.

The Fourier transform of the baseband signal can be obtained by applying the Fourier transform to each individual term and adding them up. The Fourier transform of the given signal x(t) is:

X(f) = 2δ(f) + 1.5j[δ(f - 4) - δ(f + 4)] + 2j[δ(f - 8) + δ(f + 8)] + j[δ(f - 12) - δ(f + 12)] + 2j[δ(f - 16) + δ(f + 16)]

Here, it represents the Dirac delta function.

To plot the amplitude spectrum, we can plot the magnitude of the Fourier transform, |X(f)|, as a function of frequency f.

b) When the baseband signal is passed through an ideal high pass filter with a cutoff frequency of 3Hz, all frequency components below 3Hz are attenuated while those above 3Hz pass through unchanged.

Therefore, the output signal y(t) will contain only the frequency components above 3Hz.

The expression for the output signal y(t) can be obtained by removing the frequency components below 3Hz from x(t). This can be achieved by multiplying the Fourier transform of x(t), X(f), by a rectangular function that is 1 for frequencies above 3Hz and 0 otherwise. The average power of y(t) can be calculated using the expression:

P_avg = (1/T) * ∫[|y(t)|^2] dt,

where T is the period of y(t).

c) To determine the amplitude spectrum of the DSB-SC signal, we need to modulate the filtered signal y(t) with the carrier signal c(t).

The DSB-SC signal can be obtained by multiplying y(t) with c(t):

z(t) = y(t) * c(t).

The amplitude spectrum of the DSB-SC signal can be obtained by taking the Fourier transform of z(t) and plotting its magnitude |Z(f)|.

d) The average transmitted power of the DSB-SC signal can be calculated using the expression:

P_avg = (1/T) * ∫[|z(t)|^2] dt.

Parseval's theorem states that the average power of a signal in the time domain is equal to the average power of its Fourier transform in the frequency domain. Therefore, we can also verify the average transmitted power using Parseval's theorem:

P_avg = (1/T) * ∫[|Z(f)|^2] df.

By evaluating the integral on both sides, we can compare the results with the previously calculated average power.

Displacement is defined as the difference between the initial position of the particle at the start of the interval and its final position at the end of the interval.

In order to answer the given question, "Estimate the displacement of the particle on the interval [2,5] given the graph of f," we would need to see the graph of f in question. Without this information, we cannot provide a specific answer to the question.

However, in general, to estimate the displacement of a particle over a given interval, you would need to find the difference between the initial position of the particle at the start of the interval and its final position at the end of the interval. This is known as the particle's displacement.

To calculate the displacement of the particle, you would need to know its position at the beginning and end of the given interval. Depending on the situation, this could involve calculating the area under a curve, finding the slope of a line, or using other mathematical methods to determine the particle's position at various points in time.
