The expressions for the real part, imaginary part, and magnitude of the complex function f(x) = 1/(1-ix) are: Re[f(x)] = Re[1/(1-ix)] = Re[1] / Re[1-ix] = 1 / (1 - x^2), Im[f(x)] = Im[1/(1-ix)] = Im[1] / Re[1-ix] = -x / (1 - x^2) and |f(x)| = √(Re[f(x)]^2 + Im[f(x)]^2) = √(1 / (1 - x^2)^2 + (-x / (1 - x^2))^2) = 1 / |1 - ix|

Given the complex function f(x) = 1/(1-ix), where I = √-1, we can find the real part, imaginary part, and magnitude as follows:

Real part: The real part of a complex number is equal to the real part of the numerator divided by the real part of the denominator. Here, the numerator is 1, so the real part of the numerator is 1. The denominator is 1-ix, so the real part of the denominator is 1, and the imaginary part of the denominator is -x. The real part of the complex function is then given by:

Re[f(x)] = Re[1/(1-ix)] = Re[1] / Re[1-ix] = 1 / (1 - x^2)

Imaginary part: The imaginary part of a complex number is equal to the imaginary part of the numerator divided by the real part of the denominator. Here, the numerator is 1, so the imaginary part of the numerator is 0. The denominator is 1-ix, so the real part of the denominator is 1, and the imaginary part of the denominator is -x. The imaginary part of the complex function is then given by:

Im[f(x)] = Im[1/(1-ix)] = Im[1] / Re[1-ix] = -x / (1 - x^2)

Magnitude: The magnitude of a complex number is equal to the square root of the sum of the squares of the real and imaginary parts. The magnitude of the complex function is then given by:

|f(x)| = √(Re[f(x)]^2 + Im[f(x)]^2) = √(1 / (1 - x^2)^2 + (-x / (1 - x^2))^2) = 1 / |1 - ix|

Therefore, the expressions for the real part, imaginary part, and magnitude of the complex function f(x) = 1/(1-ix) are: Re[f(x)] = Re[1/(1-ix)] = Re[1] / Re[1-ix] = 1 / (1 - x^2), Im[f(x)] = Im[1/(1-ix)] = Im[1] / Re[1-ix] = -x / (1 - x^2)

and |f(x)| = √(Re[f(x)]^2 + Im[f(x)]^2) = √(1 / (1 - x^2)^2 + (-x / (1 - x^2))^2) = 1 / |1 - ix|.

What is Derivative?

Calculus defines a derivative as the rate at which one quantity, y, changes in relation to another, x. The differential coefficient of y with respect to x is another name for it. Finding a function's derivative is the process of differentiation. A function's derivative is typically represented by d/dx (f(x)) (or df/dx (or Df(x) (or f')). Let's examine the technical definition of a derivative. Two points on a function f(x) curve are (x, f(x)) and ((x + h), f(x + h)), respectively. If so, [f(x + h) - f(x)]/(x + h - x) = [f(x + h) - f(x) / h] will be the slope of the secant line through these points. The second point overlaps the first point in the figure below when the distance between two points is nearly equal to 0 (i.e., as h approaches 0), and the secant line turns into the tangent line. Calculus refers to the slope of the tangent line as the function's derivative.

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

(8x+16) + (9x+11) = 180

17x + 27 = 180

180 - 27 = 153

17x = 153

153/17 = 9

x = 9

Answer:

To solve the equation 8x+16+9x+11=180, add 8x and 9x to both sides to get 17x+27=180. Subtract 27 from both sides to get 17x=153. Divide both sides by 17 to get x=9.

The solution to the inequality in question is less than or equal to 4300 pounds and 2.6875 cubic yards of sand can be hauled in the truck to still classify as a passenger vehicle.

From the question itself, we can deduce that the inequality is -

Let us assume that the amount of stuff carried by the vehicle is = x

So, the inequality becomes -

= 4200 + x ≤ 8500 pounds

So, if we solve this we will find that the weight of stuff to be carried is going to be -

= x ≤ 8500 - 4200

= x ≤  4300

It should be no more than 4300 pounds.

We can still classify it as a passenger vehicle by carrying only 1.4655 pounds of sand because -

= 2.6875 *1600 = 4300 pounds

This means that by carrying 2.6875 pounds we maintain the rules to remain a passenger vehicle.

The formula v · v = kvk2 is true for all vectors v in Rn. This is because the dot product of a vector and itself is equal to the magnitude of the vector squared. The dot product of two vectors is defined as the sum of the products of their components. Therefore, when a vector v is multiplied by itself, the result is the sum of the squares of all its components. The magnitude of a vector is defined as the square root of the sum of the squares of its components.

To evaluate g(-5), you simply plug in -5 for x in the equation:

g(-5) = (-5)²-10 which is 25 - 10 which is 15. Therefore, g(-5) = 15

Answer:

The volume of each cylinder is given by the formula: V = πr^2h, where r is the base radius and h is the height of the cylinder.

When 25 cylinders are put into the half-filled container, the water level rises to the top of the container, which means that the total volume of the 25 cylinders is equal to the volume of the container. Let's assume the volume of the container is V_container.

So, 25 * πr^2 * h = V_container

Dividing both sides by 25πh gives: r^2 = V_container / (25πh)

Taking the square root of both sides gives: r = √(V_container / (25πh))

Since h = 10 cm, we can substitute this value in the formula above: r = √(V_container / (25π * 10))

Since r is the base radius of the cylinder, it must be positive. So, the final equation becomes:

r = √(V_container / (25π * 10)) cm = 5√(5/π) cm. shown

By using 3.14 for the value of π, we can calculate the value of r:

r = 5√(5/π) = 5√(5/3.14) = 5 * √(5/3.14)

= 5 * √(1.5873) = 5 * 1.259 = 6.295 cm (rounded to the first decimal place)

So, the base radius of the cylinder is approximately 6.3 cm.

Step-by-step explanation:

The bacteria will reach its maximum size at t = 8.94 weeks.

To find when the bacteria will reach its maximum size, we need to find the maximum value of p(t). The first step is to find the derivative of p(t):

dp(t)/dt = -8000(t^2 - 80)/(80 + t^2)^2

Next, we need to find the critical points of this derivative by setting it equal to 0 and solving for t:

dp(t)/dt = 0

-8000(t^2 - 80)/(80 + t^2)^2 = 0

t^2 - 80 = 0

t = √80

t = 4√5

t ≈ 8.94

Since t = 4√5 is the only critical point, we can see that it is a local maximum. To confirm this, we need to find the second derivative and evaluate it at t = 0:

d^2p(t)/dt^2 = 16000t (t^2 - 240) / (80 + t^2)^3

d^2p(t)/dt^2 = 160000 * -160 / (80 + 80)^3 < 0

Since the second derivative at t =  4√5 is less than 0, it is a local maximum.

The equation y = 2.72x can be used to calculate the price of gasoline in terms of the number of gallons purchased.

The equation y = 2.72x can be used to calculate the total price of any number of gallons of gasoline. In this equation, y represents the total price and x represents the number of gallons of gasoline. In this equation, y represents the total price and x represents the number of gallons. If we input 15 gallons into the equation, we can calculate the total price of gasoline. To do this, we must substitute 15 for x in the equation, giving us y = 2.72(15). We can then calculate the total price by multiplying 2.72 and 15, which yields 40.8.

The average acceleration over the given time interval is option C -10 m/s²

By dividing the change in velocity by the change in time, the average acceleration will be determined. Therefore, let's first determine the velocity function:

x = 4t² - 3t³

v = dx / dt

v = d( 4t² - 3t³) / dt

v = 8t - 9t²

Then,

at t = 0 sec , v = 0 m/s.

at t = 2 sec , v = 8(2) - 9(2²) = 16 - 36 = -20 m/s.

Average acceleration;

The rate of change in velocity is referred to as the average acceleration. To calculate the average acceleration of anything, we divide the change in velocity by the time since the initial measurement. A crazy ball's average acceleration, for instance, would be 20 cm/s/s if its velocity rose from 0 to 60 cm/s in 3 seconds.

The normal distribution chart below for the weights of the factory are 9.02, 9.07, 9.12, 9.17, 9.22 from left to right.

The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability. When data points are closely spaced from the mean, there is a small variation, and when they are far spaced from the mean, there is a large variation. The standard deviation determines how much the values deviate from the mean. The most popular way to assess dispersion is standard deviation, which is based on all values.

From the given samples of 9oz of chips we have the following values:

Mean = 9.12 ounces
