The diagram shows a pyramid with a square base.
The triangular faces are congruent isosceles triangles.
(a) Write down the number of planes of symmetry of this pyramid.

In the equation , Felipe is correct.

What is equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Here the given equation is (372) (675) =18k7.

We know that the factor is a number that divides the another number and leaves no reminder .

If we divide 18k7 by 372 the we get remainder 675. So 372 is not factor of 18k7.

But 372 is divides the number 18k7.

Hence Felipe is correct.

To determine the materials cost for the brooch, we need to know the area of each material used in the brooch. Let's say that the brooch is made up of a 5 cm x 5 cm square of silver, a 2 cm x 2 cm square of copper, and a 3 cm x 1 cm rectangle of stone.

The area of the silver sheet is 5 cm x 5 cm = 25 cm^2, so the cost of the silver is 25 cm^2 x $9.75/cm^2 = $243.75.

The area of the copper sheet is 2 cm x 2 cm = 4 cm^2, so the cost of the copper is 4 cm^2 x $3.25/cm^2 = $13.

The area of the stone is 3 cm x 1 cm = 3 cm^2, so the cost of the stone is 3 cm^2 x $1.75/cm^2 = $5.25.

Therefore, the total materials cost for the brooch is $243.75 + $13 + $5.25 = $262.

The mean and the median of the data set is given as the median, 4, is greater than the mean, 3. The correct answer is option a.

To find the mean of the data set, we add up all of the numbers and divide by the total number of days. So, the mean is (1+4+5+5+1+5+5)/6 = 3.

To find the median, we first need to put the numbers in order from least to greatest: 1, 1, 4, 5, 5, 5. The median is the middle number, which in this case is 4.

Now we need to determine which value is greater. The options are:

A. The median, 4, is greater than the mean, 3.
B. The mean, 3, is greater than the median, 4.
C. The mean, 4, is greater than the median, 2.
D. The median, 5, is greater than the mean, 0.

We can eliminate options B and D because they don't make sense. The mean cannot be less than 0, and the median cannot be less than the mean.

Option A is correct. The median, 4, is greater than the mean, 3. This makes sense because there are two 1's in the data set, which bring down the mean. However, the median is not affected by outliers like this, so it remains higher.

Option C is incorrect because the mean is not 4, it is 3.

In summary, the mean of the data set is 3 and the median is 4. The median is greater than the mean, which is represented by option A.

To find the measure of angle W in the kite WXYZ, we can use the properties of kites. In a kite, the two opposite angles formed by the intersection of the diagonals are equal. Let's denote the measure of angle W as "x."

Step 1: Start with the given information that WXYZ is a kite.

Step 2: Recall that the diagonals of a kite intersect at right angles. Let's label the intersection point of the diagonals as point P.

Step 3: Draw the diagonals WX and YZ, which intersect at point P.

Step 4: Recognize that angles WXP and ZYP are congruent. Therefore, the measure of angle WXP is also x.

Step 5: Observe that the sum of the angles in a triangle is 180 degrees. Since triangle WXP is a triangle, we can write the equation: x + 90 + 90 = 180.

Step 6: Simplify the equation: x + 180 = 180.

Step 7: Subtract 180 from both sides: x = 0.

Step 8: Analyze the result. The measure of angle W, denoted by x, is equal to 0 degrees.

Therefore, the measure of angle W in the kite WXYZ is 0 degrees.

This requires an online learning algorithm that adapts to the changing costs of each expert and helps us make optimal choices

In this scenario, we can think of the slot machines as experts providing us with advice on which machine to play each day. The cost of taking advice from each expert, represented by cti, is the amount we lose by playing that particular machine.

To minimize our losses and regret, we want to choose the expert (i.e., slot machine) with the lowest cost each day. However, it's important to note that the cost of taking advice from each expert may change each day, so we need to constantly evaluate and adjust our choices.

To formalize this problem as an optimization task, we can use the concept of regret. Regret measures how much worse off we are by not knowing the best expert in advance. In other words, it's the difference between our cumulative losses if we always chose the best expert versus the losses we actually incur by following different experts each day.

To minimize our regret R, we need to choose the best expert as often as possible. One way to achieve this is by using an online learning algorithm that updates our choice based on the outcomes of each day's play. By continuously monitoring the performance of each slot machine, we can adjust our strategy and minimize our losses over time.

In summary, to minimize our losses while gambling at a casino, we need to treat each slot machine as an expert providing us with advice. We must choose the expert with the lowest cost each day and constantly update our strategy to minimize regret.

62% of the dancers did not get into the show.

To find the percentage of dancers who did not get into the show.

First, identify the total number of dancers auditioning and the number of dancers who did not get into the show.

In this case, there are 150 dancers in total, and 93 of them did not get in.
Next, divide the number of dancers who did not get into the show by the total number of dancers auditioning.

This will give us the proportion of dancers who did not get in.
  Proportion = (Number of dancers who did not get in) / (Total number of dancers)
  Proportion = 93 / 150
Finally, to find the percentage, multiply the proportion by 100:

The area bounded by y = in(x)/x, y = 0, and x = e¹⁹ is  361/2 square units.

To find the area bounded by the curves y = ln(x)/x, y = 0, and x = e¹⁹, we need to integrate the function ln(x)/x with respect to x over the interval [1, e¹⁹].

∫[1, e¹⁹] ln(x)/x dx

To solve this integral, we use integration by parts with u = ln(x) and dv/dx = 1/x dx.

∫ ln(x)/x dx = ∫u dv = uv - ∫v du

where v = ln(x) and du/dx = 1/x dx.

∫ ln(x)/x dx = ln(x)^2/2 |[1, e¹⁹] - ∫[1, e¹⁹] (1/x)(ln(x)/2) dx

Evaluating the definite integral at the limits gives:

ln(e¹⁹)²/2 - ln(1)²/2 = 361/2

The transformation of the function g(x) is g(x) = 250 * 5^x - 1. It represents a vertical stretch by a scale factor of 2, a shift of 3 units to the left, and a downward shift of 1 unit applied to the original function f(x) = 5^x.

- Vertical stretch by a scale factor of 2: Multiply the output by 2.

- Shift 3 units to the left: Replace x with x + 3.

- Shift 1 unit down: Subtract 1 from the output.

Thus, the function g(x) can be written as:

g(x) = 2 * f(x + 3) - 1

Substituting f(x) = 5^x, we get:

g(x) = 2 * 5^(x + 3) - 1

Simplifying:

g(x) = 2 * 125 * 5^x - 1

g(x) = 250 * 5^x - 1

The function g(x) is given by g(x) = 250 * 5^x - 1. It represents a vertical stretch by a scale factor of 2, followed by a shift of 3 units to the left, and a downward shift of 1 unit, applied to the original function f(x) = 5^x.

The transformation increases the steepness of the graph, shifts it to the left, and shifts it downward. The expression 250 * 5^x represents the vertical scaling, and the -1 accounts for the vertical shift downward. Overall, g(x) is a modified version of f(x) with these transformations applied.

Point B is the image of point A under a rotation about the origin.

Rotation is a transformation in which an object or a point is turned around a fixed point or a fixed axis. The fixed point or axis is called the center of rotation, and the angle of rotation specifies the amount and direction of the turn. When an object is rotated, its orientation changes but its shape and size remain the same.

For example, if you rotate a square by 90 degrees around its center, it will look the same as before, but it will be oriented differently. Similarly, if you rotate a point in a coordinate system around the origin, its position will change, but its distance from the origin will remain the same.

Rotations are commonly used in geometry, physics, and engineering to describe the motion of objects, such as the rotation of the Earth around its axis or the rotation of a wheel on an axle. They are also used in computer graphics to create animations and in robotics to control the movement of robotic arms and other devices.

When point A is rotated about the origin to form point B, the distance between the origin and each point remains the same. The direction from the origin to point A and the direction from the origin to point B are related by the angle of rotation. Specifically, point B is the image of point A under a rotation about the origin.

To find the derivative (f'(x)) of the function f(x) = 2x^4 In x, we will need to use the product rule and the chain rule of differentiation.

Using the product rule, we have:

f'(x) = [2(In x)](4x^3) + [2x^4](1/x)

Simplifying this expression, we get:

f'(x) = 8x^3 In x + 2x^3

Therefore, the derivative of f(x) is f'(x) = 8x^3 In x + 2x^3.
Hi! To find the derivative f'(x) of the function f(x) = 2x^4 * ln(x), we'll use the product rule. The product rule states that if you have a function h(x) = u(x)v(x), then h'(x) = u'(x)v(x) + u(x)v'(x). In this case, u(x) = 2x^4 and v(x) = ln(x).

First, find the derivatives of u(x) and v(x):
u'(x) = d(2x^4)/dx = 8x^3
v'(x) = d(ln(x))/dx = 1/x

Now, apply the product rule:
f'(x) = u'(x)v(x) + u(x)v'(x)
f'(x) = (8x^3)(ln(x)) + (2x^4)(1/x)

Simplify the expression:
f'(x) = 8x^3 * ln(x) + 2x^3

Since the team only opened a new box after finishing the previous one, the team opened 27 - 1 = 26 boxes of juice in total.

To explain this solution in more detail, we can use basic arithmetic. We know that the mom bought 7 boxes of juice, each containing 8 juice boxes,

so the total number of juice boxes is 7 x 8 = 56. After the team drank all the juice they wanted, there were 29 juice boxes remaining. This means that the team drank 56 - 29 = 27 juice boxes.

Since the team only opened a new box of juice after finishing the previous one, the number of boxes opened will be one less than the total number of juice boxes consumed.

Therefore, the team opened 27 - 1 = 26 boxes of juice in total. It is important to note that this assumes that the team opened all the boxes they consumed and did not drink any juice directly from the remaining boxes.

Answer:

To solve this trigonometric identity, we need to use the definitions of the trigonometric functions and some algebraic manipulation. Here's how we can do it:

cos 14° - sin 14°/ cos 14° + sin 14°

= (cos 14°/cos 14°) - (sin 14°/cos 14°)/(cos 14°/cos 14°) + (sin 14°/cos 14°) (multiplying the numerator and denominator of the second term by cos 14°)

= 1 - tan 14°/1 + tan 14° (using the definitions of cosine and sine, and dividing both terms by cos 14°)

= (1 - tan²14°)/(1 + tan 14°) (using the identity 1 + tan²θ = sec²θ)

= 1/cot 14° - cot 14° (using the definition of cotangent and simplifying the numerator)

= cot 90° - cot 14° (using the identity cot(90° - θ) = tan θ)

= cot (90° + 14°) (using the identity cot(θ + 90°) = -tan θ)

= cot 104°

Since cot(104°) = cot(180° - 76°) = -cot 76°, we can also write the final answer as -cot 76°.

Therefore, the given identity is true, and we have shown that:

cos 14° - sin 14°/ cos 14° + sin 14° = cot 59​ = -cot 76°.

The ratio of Kaido's age to Hiroshi's age to Saitama's age is 5:8:24.

Hiroshi is 6 years older than Kaido. Saitama is three times as old as Hiroshi. The sum of their three ages is 79.

Therefore, the ratio of Kaido's age to Hiroshi's age to Saitama's age can be calculated as follows:

Hence,

let

x = Kaido age

Hiroshi age = 6 + x

Saitama age = 3(6 + x) = 18 + 3x

Therefore,

x + 6 + x + 18 + 3x = 79

5x = 79 - 24

5x = 50

x = 50 / 5

x = 10

Therefore,

x = Kaido age = 10 years

Hiroshi age = 6 + x = 6 + 10 = 16 years

Saitama age = 3(6 + x) = 18 + 3x = 18 + 3(10) = 48 years

Hence, the ratio of there ages are as follows:

10:16:48

The duration of days after which the individual will run out of iced tea is 4 days, under the condition that  a pitcher can hold 13 cups of iced tea. The individual drinks 1. 75 cups of the tea every morning and 1. 5 cups of the tea each evening. 

So to solve this problem we have to relie on the basic principles of division
Total amount of tea consumed per day = 1.75 cups (morning) + 1.5 cups (evening)
= 3.25 cups
Total amount of tea in the pitcher = 13 cups
Number of days before running out of iced tea = 13 cups / 3.25 cups per day
= 4 days
Then, the duration of days until the iced tea runs out is 4 days.

To reflect point C across the y-axis, we change the sign of the y-coordinate, but keep the x-coordinate the same. If point C is located at (x, y), then its reflected image, C', would be located at (-x, y).

Since we don't have the coordinates for point C, we cannot plot it accurately. However, we know that its reflected image would be located at (-x, y), so we can label it as C' for now.

So, the reflected image of point C across the y-axis, C', would be located at (-x, y). Thus, we can label the points B and C' in the coordinate plane as follows
