The value of {r} is 64 and the value θ is 30°.

A complex number is a number of the form (a + bi), where [a] and [b] are real numbers and [i] is equal to [tex]\sqrt{-1}[/tex] . The general form of the complex number representation is (a + ib). In this, [a] is called real part and [ib] is called imaginary part.

Given is the complex number -

z = 4√3 - 4i

We can write the value of {r} as -

r = (4√3)² + (- 4)²

r = 16 x 3 + 16

r = 64

θ = tan ⁻¹(4/4√3)

Answer: Answer: 475

Because i divided 500 by 5% and it gives u 475.

The original fraction is -5. Note that this is a negative fraction, which may not be meaningful in certain contexts.

Let's call the original fraction "x".

From the first condition, we have:

x + 4 / x's denominator = 3/4

From the second condition, we have:

x / (x's denominator + 2) = 1/2

We can substitute x's denominator in the first equation with (x's denominator + 2) from the second equation:

x + 4 / (x's denominator + 2) = 3/4

Next, we can cross-multiply and solve for x:

4x + 16 = 3x's denominator + 6

x's denominator = 4x + 10

Substituting back into the second equation:

x / (4x + 10) = 1/2

Multiplying both sides by (4x + 10) to isolate x:

2x = 4x + 10

Solving for x:

-2x = 10

x = -5

The solution is, by force wind move the sail.

As the boat is sailing, the wind will be faster than the boat. This fast wind is obstructed by the sail. That is, the fast wind gets slowed down by the sail because the sail pushes the wind backwards which slows down the wind. This will make the wind push the boat forward thereby accelerating the boat.

Answer:

To find the solution of a linear system, we need to find the values of x and y that satisfy both equations. One method to solve a system of linear equations is substitution. We can use the first equation to find the value of y in terms of x, and substitute it into the second equation.

y = 1/2x + 1

y = 3/2x + 4

We substitute the first equation into the second equation:

3/2x + 4 = 1/2x + 1

Now we simplify:

2x = 3

x = 3/2

Finally, we substitute x = 3/2 into either equation to find y:

y = 1/2 * 3/2 + 1 = 2

So, the solution of the system is (3/2, 2). Out of the given options, only (3/2, 7/4) has the same values of x and y.

Therefore, the answer is (C) (3/2, 7/4).

Answer:

Degrees = Radians x 180/π

or

Degrees = 57.2958  x radians

Step-by-step explanation:

1 radian = 180/π degrees

1 radian = 57.2958 degrees

Multiply radians by this factor of 57.2958  to get the equivalent measure in degrees

π radians = 180°

2π radians = 360° which is the number of degrees in a circle

For anything greater than 2π radians you will have to subtract 360°

For example, 7 radians using the formula is 7 x (57.2958  ) ≈ 401.07°

But this still falls in the first quadrant, so relative to the x-axis it is
401.07 - 360 = 41.07°

The distance of the run is 11.67 miles.

Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.

Speed is a scalar quantity as it only has magnitude and no direction.

Given that,

Speed of first jogger = 5 mph

Speed of second jogger = 4 mph

Let d be the distance in miles of the run.

Time taken by first jogger be t hours.

Time taken by second jogger = t + (35 minutes) = t + (7/12) hours

Speed = Distance / Time

5 = d / t and 4 = d / (t + 7/12)

d = 5t and d = 4 (t + 7/12)

5t = 4 (t + 7/12)

5t = 4t + 7/3

t = 7/3 hours

d = 5t = 11.67 miles.

Hence the distance ran by both joggers is 11.67 miles.

The required standard deviation of the new data set is 9.

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

When 16 is added to each number in the data set, the variance of the new data set is not affected. The variance of a data set is the average of the squared deviations of the data values from the mean, and adding a constant to each data value shifts the mean but does not affect the deviations or their squares.

However, the standard deviation, which is the square root of the variance, will change because the standard deviation is expressed in the same units as the original data, while the variance is expressed in squared units. To find the standard deviation of the new data set, we need to take the square root of the variance, which is 81, and add 16 to each data value. The standard deviation of the new data set is equal to the square root of 81 + 16 = 9.

So, the standard deviation of the new data set is 9.

Total no. of sedans requested by the second group = 3

Total no. of minivans requested by the second group = 2

Total no. of people that can be seated = 19

Now, the total no. of people for each type of taxi can seat = 13 passengers / 3 taxis.

By rounding up to the nearest value,  4 passengers per taxi.

No. of sedan seats = No. of passengers of a minivan.

Step-by-step explanation:

The trapezoidal rule is a numerical integration method that frequently overestimates the real value of a function's definite integral.

The trapezoidal rule is a strategy for approximating the definite integral in calculus. The trapezoidal rule works by computing the area of the region under the graph of the function f(x) that is approximated as a trapezoid. The trapezoidal rule is commonly used to calculate the area under curves. This is achievable if the overall area is divided into smaller trapezoids rather than rectangles. The Trapezoidal Rule integration determines the area by approximating the area under a function's graph as a trapezoid. The midway rule uses rectangular areas to approximate the definite integral, whereas the trapezoidal rule uses trapezoidal approximations to approximate the definite integral. Simpson's approach works by first approximating the original function with piecewise quadratic functions.

The equation of the perpendicular line is y = -4/3 x + 12.

The equation of the parallel line is y = 3/4 x + 2.

Perpendicular lines are two lines that cross one other and create a 90-degree angle.

Consider the line y= (3/4)x+6.

To find the equation of the line that is perpendicular to the line y = (3/4)x + 6 and passes through the point (-8, -4), we need to find the slope of the perpendicular line.

Since the slope of a line perpendicular to another line is the negative reciprocal of the original line.

The slope of the line y = (3/4)x + 6 is m = 3/4.

Therefore, the slope of the perpendicular line is -4/3.

Plugging in the values we have, we get:

y - (-4) = -4/3 (x - (-8))

Simplifying, we get:

y + 4 = -4/3 x + 8

y = -4/3 x + 12

So the equation of the perpendicular line is y = -4/3 x + 12.

To find the equation of the line that is parallel to the line y = (3/4)x + 6 and passes through the point (-8, -4), we need to use the same slope, m = 3/4, as the original line.

Using the point-slope form of a line, we get:

y - (-4) = 3/4 (x - (-8))

Simplifying, we get:

y + 4 = 3/4 x + 6

y = 3/4 x + 2

So the equation of the parallel line is y = 3/4 x + 2.
