What is the area of this figure?

Enter your answer in the box.

Answer:

To complete each statement, we will need to perform some operations on the given complex numbers w and z.

1. Find w^3:

We can use De Moivre's theorem to raise w to the third power:

w^3 = [2(cos(90°) + i sin(90°))]^3

= 2^3(cos(90°3) + i sin(90°3))

= 8(cos(270°) + i sin(270°))

Therefore, w^3 = 8(cos(270°) + i sin(270°)).

2. Simplify z^2:

To simplify z^2, we can use the identity cos(2θ) = 2cos^2(θ) - 1 to simplify the cosine term:

z^2 = [√(cos(250°) + i sin(225°))]^2

= cos(2250°) + i sin(2225°)

= cos(500°) + i sin(450°)

= cos(140°) - i sin(90°)

Therefore, z^2 = cos(140°) - i sin(90°).

Note: We can also simplify the square root of the cosine term using the identity cos(2θ) = 1 - 2sin^2(θ), but this would result in a more complicated expression for z^2.

3. Find the product wz:

We can simply multiply w and z using the distributive property:

wz = 2(cos(90°) + i sin(90°)) * √(cos(250°) + i sin(225°))

= 2√(cos(90°)cos(250°) - sin(90°)sin(250°) + i(cos(90°)sin(250°) + sin(90°)cos(250°)))

= 2√(-sin(250°) + i cos(250°))

Therefore, wz = 2√(-sin(250°) + i cos(250°)).

the probability that no two people of the same sex sit next to each other is 2/7.

One way to solve this problem is to use the principle of inclusion-exclusion. Let A be the event that the boys sit next to each other, and let B be the event that the girls sit next to each other. Then, we want to find the probability of the complement of (A or B), which is the probability that neither A nor B occurs.

The probability of A occurring is the same as the probability of the 5 boys sitting in a row, which is 5! (since each order is equally likely). Similarly, the probability of B occurring is 5!. However, we need to subtract the probability of A and B occurring simultaneously. This can be seen as follows: once the boys are seated in a row, there are 6 spaces (between or on the ends) where the girls can be seated. Thus, the probability of A and B occurring is 2*5!*6.

Therefore, the probability of neither A nor B occurring (i.e., the probability that no two people of the same sex sit next to each other) is:

P(neither A nor B) = 1 - P(A or B) = 1 - [P(A) + P(B) - P(A and B)]

= 1 - [(25!) / 10! - (25!6) / 10!]

= 1 - [25!*(1 - 6/9!)]

= 2/7

Answer: Oy = 15.5x

Step-by-step explanation: Gas mileage refers to the quantity of miles driven per unit volume of gasoline, typically expressed as "miles per gallon." In the context of the present inquiry, the vehicle in question exhibited a capacity to traverse a distance of 310 miles subsequent to the utilization of 20 gallons of gasoline. Thus, it is possible to calculate the gas mileage through the division of the quantity of gas consumed by the distance elapsed, resulting in:

The fuel efficiency of a vehicle, represented by the metric of gas mileage, is typically calculated by the ratio of distance traveled in miles to the amount of fuel consumed in gallons. In the present case, the gas mileage is equivalent to the quotient of 310 miles by 20 gallons, resulting in an efficiency rating of 15.5 miles per gallon.

The values of x for which the function f(x) = x³ + 3x² - 9x + 7 is increasing are (-∞, -3) and (1, +∞).

To find the values of x for which the function f(x) = x³ + 3x² - 9x + 7 is increasing, we need to take the derivative of the function and determine where the derivative is positive.

f(x) = x³ + 3x² - 9x + 7

f'(x) = 3x² + 6x - 9

To find where f(x) is increasing, we need to find the values of x where f'(x) > 0.

3x² + 6x - 9 > 0

Simplifying this inequality, we get

x² + 2x - 3 > 0

Factoring the left side of the inequality, we get

(x + 3)(x - 1) > 0

The critical points of f(x) occur when f'(x) = 0 or when the denominator of f'(x) is undefined. The denominator of f'(x) is always defined, so we only need to find where f'(x) = 0

3x² + 6x - 9 = 0

Dividing both sides by 3, we get

x² + 2x - 3 = 0

Factoring the left side of the equation, we get

(x + 3)(x - 1) = 0

So the critical points of f(x) are x = -3 and x = 1.

Now we can use a sign chart to determine the intervals where f'(x) > 0.

a. The correlation coefficient: ≈ -0.184

b. The correlation coefficient r ≈ -0.184, which is close to 0. This suggests that there is a weak negative correlation between the x and y values in the data.'

To find the line of best fit using a linear regression algorithm, we need to find the slope (m) and y-intercept (b) of the equation in the form y = mx + b.

We will start by calculating some statistics from the given data.

First, let's find the means of x and y:

x_mean = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9) / 9 = 45 / 9 = 5

y_mean = (8 + 4.037 + 7.200 + 4.180 + 4.763 + 1 + 1.047 + 2.436 + 1.844) / 9 ≈ 34.507 / 9 ≈ 3.834

Next, we need to find the sum of the product of the differences between each point and the mean for both x and y:

Σ((x - x_mean) * (y - y_mean)) = (1 - 5) * (8 - 3.834) + (2 - 5) * (4.037 - 3.834) + ... + (9 - 5) * (1.844 - 3.834) ≈ -8.311

We also need to find the sum of the squared differences between each x and the mean of x:

Σ((x - x_mean)^2) = (1 - 5)^2 + (2 - 5)^2 + ... + (9 - 5)^2 = 60

Now, we can calculate the slope (m):

m = Σ((x - x_mean) * (y - y_mean)) / Σ((x - x_mean)^2) ≈ -8.311 / 60 ≈ -0.1385

To find the y-intercept (b), use the formula:

b = y_mean - m * x_mean ≈ 3.834 - (-0.1385) * 5 ≈ 4.525

Now we have the line of best fit equation:

y = -0.1385x + 4.525

a. To find the correlation coefficient (r), we need to divide the covariance of x and y by the product of the standard deviations of x and y.

First, let's find the covariance:

cov(x, y) = Σ((x - x_mean) * (y - y_mean)) / (n - 1) ≈ -8.311 / 8 ≈ -1.039

Next, find the standard deviations of x and y:

sd_x = sqrt(Σ((x - x_mean)^2) / (n - 1)) = sqrt(60 / 8) ≈ 2.738

sd_y = sqrt(Σ((y - y_mean)^2) / (n - 1))

sd_y = sqrt((8 - 3.834)^2 + (4.037 - 3.834)^2 + ... + (1.844 - 3.834)^2) / 8 ≈ sqrt(33.904) / 8 ≈ sqrt(4.238) ≈ 2.058

Now we can calculate the correlation coefficient:

r = cov(x, y) / (sd_x * sd_y) ≈ -1.039 / (2.738 * 2.058) ≈ -0.184

b. The correlation coefficient r ≈ -0.184, which is close to 0. This suggests that there is a weak negative correlation between the x and y values in the data.'

Step-by-step explanation:

Because same numbers = same y intercept but I'm not sure

Answer:

  1) The image has the same slope, different y-intercept

Step-by-step explanation:

You want the relationship between the line 3x -5y = 4 and its image dilated by a factor of 5/3 centered at the origin.

Dilation about the origin multiplies every coordinate by the dilation factor. Dilation does not change slopes or angles, but it changes lengths by the dilation factor.

When the equation of a line is written in standard form, the dilation of it effectively multiplies the constant by the dilation factor.

The given line has intercepts ...

  ax +by = c

  x-intercept = c/a = 4/3

  y-intercept = c/b = -4/5

If these values are multiplied by the dilation factor 5/3, they become ...

  x-intercept' = (5/3)(4/3) = 20/9 = 2 2/9

  y-intercept' = (5/3)(-4/5) = -4/3 . . . . . note the y-intercept has changed

The slope of the given line can be determined from its intercepts:

  m = (-y intercept)/(x intercept) = -(-4/5)/(4/3) = 3/5

Since both of these intercepts are multiplied by the same dilation factor, their ratio remains unchanged. The slope of the dilated line is the same.

Effectively, the dilated line's equation is ...

  3x -5y = 4(5/3)

  3x -5y = 20/3

The "Perimeter" of a rectangle is defined as the "total-length" of the outer boundary.

The length of the rectangle can be calculated as the difference between the x-coordinates of the vertices on the same vertical side.

In this case, the "x-coordinates" of vertices on same vertical side are 4 and -2.

So, the length of the rectangle is = 4 -(-2) = 6 feet.

Similarly, the width of rectangle is calculated as difference between "y-coordinates" of vertices on same horizontal side.

In this case, the "y-coordinates" of vertices on same horizontal side are 1 and -3.

AC and BD are  the diagonals of the MNOP, the diagonals of the rectangle MNOP bisect each other and are congruent.

 A rectangle and a rectangle  are quadrilaterals that share the following properties: Opposite sides are equal. Two diagonals are the same length. It has two  class 2 reflection symmetries and a rotational symmetry (through 180°).  To show that the diagonals of a rectangle bisect each other and are congruent, we can use the following proof:

Proof:

Let MNOP be a rectangle whose diagonal MO and diagonal NP intersect at  Q.

First we  show that the diagonals bisect each other. Since MNOP is a rectangle, we know that opposite sides are parallel and congruent. Therefore, we can draw segment MP and segment NO which are both parallel  and congruent to each other.

Now consider the triangle MON. Since segment MP is parallel to segment NO, we know that angles MNO and MON are alternate interior angles and are congruent. Similarly, the angles NMO and ONM are also congruent. Therefore, triangle MON is an isosceles triangle with legs MO and NO. This means that the height drawn from Q to the side MN (which is the perpendicular bisector of MO and NO) bisects MO and NO. Similarly, the height drawn from Q to the side OP bisects OP. Therefore we have shown that the diagonals of a rectangle bisect each other.

 Next, we  show that the diagonals are congruent. Since MNOP is a rectangle, we know that opposite sides are parallel and congruent. Therefore, MP is compatible with NO and MO is compatible with NP. Using the fact that the diagonals bisect each other, we can write:

MQ = QO (because the height drawn by Q to the side MN divides MO and NO)

and

NQ = QP (because the height drawn from Q to the side OP divides NP and MO)

Combining these two equations, we get:

MQ + NQ = QO + QP

But we also know that MO is NP-consistent, so we can substitute:

MQ+ NQ = MO + MO

Simplification:  

MQ + NQ = 2MO

Therefore, we have shown that the diagonals of a rectangle are congruent.  Therefore, we have shown that the diagonals of a rectangle bisect each other and are congruent as necessary.

Translation, dilation with center (0,0)

Two translations

In mathematics, a transformation refers to a process that changes the size, shape, position, or orientation of a geometric figure or an object in a coordinate plane or space. There are several types of transformations, such as translation, rotation, reflection, and dilation, which are used to alter the original figure to create a new one that is similar or congruent to the original. Transformations are used in geometry, algebra, and other branches of mathematics to study and understand various properties of geometric shapes and objects.

Here,

For the first set, if we perform a translation followed by a dilation with center (0,0), the result will be the same as if we perform the dilation first followed by the translation. This is because the dilation does not change the direction of the translation, and the center of dilation is at the origin, so the translation is unaffected.

For the second set, any two translations can be combined to form a single translation, so the order in which they are performed does not matter.

Answer:

To find the probability of choosing a hat, we divide the number of hats by the total number of choices = #hat / #clothes = 5 / (5+10+15+20) = 5 / 50 = 1 / 10 = 0.1.

Step-by-step explanation:

The container can contains 3,000 pounds of chemicals.

One cubic foot of a chemical weighs 50 pounds which means 1 ft³ of chemical = 60 pounds

We must  find how many pounds in the container whose dimension 6 ft, 4 ft and 2.5 ft. So, the l = 6 ft, b = 4 ft and h = 2.5 ft.

Volume of box = L*B*H

Volume of box = 6 x 4 x 2.5

Volume of box = 60 ft³

From 1 ft³ of chemical = 60 pounds; then, the 50 ft³ of chemical will be:

= 50 x 60

= 3,000 pounds

The image of the point (0, 3) after dilation by a scale factor of 2 centered at the origin is (0, 6).

Dilation is a transformation in which a figure is enlarged or reduced by a scale factor.

We are to find the image of (0,3) after a dilation by a scale factor of 2 centered at the origin.

The scale factor is 2, which means the figure will be enlarged.

To find the image of (0, 3) after dilation, we multiply its x-coordinate and y-coordinate by 2.

Hence;

(0, 3)

Multiply the coordinates by 2.

(0 × 2, 3 × 2)

= (0, 6)

Therefore, the image after dilation is (0, 6).
