.The circumference is the distance around the circle. The circumference is equal to two times pi times the radius (C = 2*pi*r). Because the diameter is equal to two times the radius, the circumference is equal to the diameter times pi (C = D*pi), where pi is about 3.14… The diameter of a circle is 2 units.

Therefore , the solution of the given problem of inequality comes out to be x = 12.5°.

An inequality in mathematics is a linear relationship or a set of integers even without equal sign. Equilibrium follows equity ineluctably. Inequality exists between two variables when they are not equal. There are distinctions between equality and inequality. I've selected the most prevalent symbol because when variables aren't identical or comparable (). Any number of inequalities, no matter how little or large, can be used to compare values.

Here,

Given :4x -10 = 40

=> 4x = 40 + 10

=>  4x =50

=> x  =50/4

=>x= 12.5°

Therefore , the solution of the given problem of inequality comes out to be x = 12.5°.

Answer:

The distance is 6.9115 miles.

Step-by-step explanation:

To solve this problem we can use a rule of three.

The length of a circumference is 2*pi*r, and if we have a fraction of the whole arc, we have that:

360 degrees -> arc of 2*pi*r

6 * (1/60) degrees -> arc of x

So we have that:

\(x * 360 = (1/10) * 2*\pi*r\)

\(x = (1/10) * 2 * \pi * 3960 / 360\)

\(x = (1/5) * \pi * 11\)

\(x = (11/5)*\pi = 6.9115\ miles\)

The distance is 6.9115 miles.

The value of x for which the functions f(x) is equal to g(x) is x equals 3.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given,  f(x) = 4x - 2 and g(x) = 2x + 4.

Now for f(x) = g(x) we have to equate 4x - 2 and 2x + 4 which is,

4x - 2 = 2x + 4.

4x - 2x = 4 + 2.

2x = 6.

x = 3.

Step-by-step explanation:

It is given that,

Jonathan wants to buy his whole basketball team new clothes.

On Amazon there is a sell for 11 shirts for $145.23

The cost of 1 shirt on amazon:

\(C=\dfrac{145.23}{11}=\$13.20\)

On Walmart sell for 23 shirts for $212.19.

The cost of 1 shirt on Walmart:

\(C=\dfrac{212.19}{23}=\$9.225\)

Step-by-step explanation:

The signal x; is a discrete signal with N samples and taking values x(n) = &**/N for n = 0,1,...,N-1. The signal Xt is the discrete Fourier transform of x; and is given by:

Xt(k) = Σn=0N-1 x(n) exp(-i2πnk/N)

This means that the Fourier transform of x(n) gives us a set of coefficients, Xt(k), that represent the contribution of each frequency, k, to the original signal x(n). In other words, the relationship between the signals x; and Xt is that Xt is a frequency-domain representation of x;.

The relationship between x and x ¢ is that x ¢ is the complex conjugate of x. This means that if x(n) = a + bi, then x ¢(n) = a - bi. In terms of the Fourier transform, this means that if X(k) is the Fourier transform of x(n), then X ¢(k) is the complex conjugate of X(k). Mathematically, this can be expressed as:

X ¢(k) = Σn=0N-1 x(n) exp(i2πnk/N)

So, the relationship between x and x ¢ is that they are complex conjugates of each other, and the relationship between their Fourier transforms, X(k) and X ¢(k), is that they are also complex conjugates of each other.
Hi! I understand that you want to know the relationship between signals x and x_t, as well as x and x', given a parameter k and a discrete signal x of duration N with values x(n) = &**/N for n = 0, 1, ..., N-1.

1. Relationship between x and x_t:
Assuming x_t is the time-shifted version of the signal x by k units, we can define x_t(n) as the time-shifted signal for each value of n:

x_t(n) = x(n - k)

Mathematically, the relationship between x and x_t is represented by the equation above, which states that x_t(n) is obtained by shifting the values of x(n) by k units in the time domain.

2. Relationship between x and x':
Assuming x' is the derivative of the signal x with respect to time, we can define x'(n) as the difference between consecutive values of x(n):

x'(n) = x(n + 1) - x(n)

Mathematically, the relationship between x and x' is represented by the equation above, which states that x'(n) is the difference between consecutive values of the discrete signal x(n), approximating the derivative of the signal with respect to time.

The number of adult tickets that were sold would be = 435 tickets.

A ticket is an official document that gives an individual access to an event.

The cost of adult tickets = $8

The cost for student tickets = $4

The number of students tickets sold = X

The number of adults tickets sold = X +30

The told number of tickets sold = 840

To find X;

X + X + 30 = 840

2x + 30 = 840

2x = 840-30

2x = 810

X = 810/2

X = 405

Therefore, the number of tickets sold for adults = 405 +30 = 435 tickets.

Answer: No, because they are not the same in slope - intercept form

Step-by-step explanation:

    First, we will distribute and simplify into slope-intercept form.

   Equation 1:

y - 3 = 4(x - 2)

y = 4(x - 2) + 3

y = 4x - 8 + 3

y = 4x - 5

   Equation 2:

y + 2 = 4(x + 7)

y = 4(x + 7) - 2

y = 4x + 28 - 2

y = 4x + 26

      We see that the answer to this question is "No, because they are not the same in slope - intercept form" as they have different y-intercepts, one being -5 and one being 26.

EXPLANATION

The player tries to throw a disc into the metal basket, so the targets that are closest togheter are represented by the BC segment because it has the closest angle and path.

The angle CBD is equal to 64 degrees by sum of interior angles definition. Furthermore, angle CBD is congruent to angle ABD.

The angle DAB is equal to 56 degrees.

In order to get an angle DAB equal to 56 degrees, the point A must be further away.

So, the only triangle that can satisfy the condition is the △BCD.

The point D is not an option because it is farther away from B and D because it has a closest angle.

So, the answer is the segment BC.

The mean of T is -10 and the standard deviation of T is √425 when X1 and X2 are independent.

To find the mean of T, we can use the properties of expected values. Since T = 11X1 - 2X2, the mean of T can be calculated as follows: E(T) = E(11X1) - E(2X2) = 11E(X1) - 2E(X2) = 11(10) - 2(20) = -10. To find the standard deviation of T, we need to consider the variances and covariance of X1 and X2. Since X1 and X2 are independent, the covariance between them is zero. Therefore, Var(T) = Var(11X1) + Var(-2X2) = 11^2Var(X1) + (-2)^2Var(X2) = 121(2^2) + 4(3^2) = 484 + 36 = 520. Thus, the standard deviation of T is √520, which simplifies to approximately √425. When X1 and X2 have a correlation of -0.76, the mean and standard deviation of T remain the same as in the case of independent variables. To calculate the probability P(T > 30) when X1 and X2 are independent, normally distributed variables, we need to convert T into a standard normal distribution. We can do this by subtracting the mean of T from 30 and dividing by the standard deviation of T. This gives us (30 - (-10))/√425, which simplifies to approximately 6.16.  We can then look up the corresponding probability from the standard normal distribution table or use statistical software to find P(T > 30). The probability will be the area under the standard normal curve to the right of 6.16.
