Verifique el diagrama en el archivo adjunto.

En el diagrama, se puede ver que el lado FC es igual al lado FB de acuerdo con el triángulo isósceles FBC.

Además, el lado FB es igual a AB ya que son paralelos entre sí.

De la declaración anterior, | FC | = | FB | y | FB | = | AB |

Esto significa | FC | = | FB | = | AB |

Por lo tanto desde | FC | = 12 m, | AB | = 12 m ya que ambos lados son iguales.

De ahí el lado | AB | se mide 12m

Answer:

Pic 1: C.

Pic 2: D.

Step-by-step explanation:

1) The sample is the number of things picked out from a population. The amount of people surveyed is the sample, so it the answer choice showing "42 residents" as the sample is among a correct option. Since C is the only one with "42" as the sample, it is the answer.

2) Boosting morale isn't a negative thing, and will ultimately make residents happier. It leans towards "yes."

Adding a machine for enjoyment also leans towards "yes", because people will then have something fun to dsitract themselves with.

Many people will have access to the machine in the lunch room. They can also have a soft drink for lunch, which adds a tasty part to their lunch. It too leans towards "yes."

In a crowded lunchroom, the soft drink machine may be crowded by many people and it could take a while to get one for yourself. It is also vulnerable to breaking from too many people using it at once. It leans towards a "No" response.

Therefore, D is the best answer.

Answer:

1014 cm²

Step-by-step explanation:

We are to find the surface area of the cube

The formula for the surface area of a cube is given as

A = 6a²

Where a = side length

From the above diagram, side length = 13cm

The surface area = 6 × 13²

= 1014 cm²

Therefore, it would take 1014 cm² of paper to cover the gift

The length of the curve \(y = \frac{1}{27}(9x^2 + 6)^\frac 32\) from x = 3 to x = 6 is 192 units

The curve is given as:

\(y = \frac{1}{27}(9x^2 + 6)^\frac 32\) from x = 3 to x = 6

Start by differentiating the curve function

\(y' = \frac 32 * \frac{1}{27}(9x^2 + 6)^\frac 12 * 18x\)

Evaluate

\(y' = x(9x^2 + 6)^\frac 12\)

The length of the curve is calculated using:

\(L =\int\limits^a_b {\sqrt{1 + y'^2}} \, dx\)

This gives

\(L =\int\limits^6_3 {\sqrt{1 + [x(9x^2 + 6)^\frac 12]^2}\ dx\)

Expand

\(L =\int\limits^6_3 {\sqrt{1 + x^2(9x^2 + 6)}\ dx\)

This gives

\(L =\int\limits^6_3 {\sqrt{9x^4 + 6x^2 + 1}\ dx\)

Express as a perfect square

\(L =\int\limits^6_3 {\sqrt{(3x^2 + 1)^2}\ dx\)

Evaluate the exponent

\(L =\int\limits^6_3 {3x^2 + 1} \ dx\)

Differentiate

\(L = x^3 + x|\limits^6_3\)

Expand

L = (6³ + 6) - (3³ + 3)

Evaluate

L = 192

Hence, the length of the curve is 192 units

Step-by-step explanation:

The solution is Option A.

The coordinate of the triangle after the translation is given by A' ( 0 , -3 ) with 4 units right and 4 units down

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

Given data ,

Let the coordinate of the triangle be represented as A

Now , the coordinate A = A ( -4 , 1 )

Now , the coordinate of the triangle after translation is A' ( 0 , -3 )

when there is a translation of the coordinate A by 4 units to the right , we get

A to 4 units right = A ( -4 + 4 , 1 )

The new coordinate of A = A ( 0 ,  1 )

Now , A to 4 units down , we get

The coordinate of A' = A' ( 0 , 1 - 4 )

The coordinate of A' = A' ( 0 , -3 )

Hence , the translated coordinate is A' ( 0 , -3 )

Answer:

y=3x+4

Step-by-step explanation:

Answer:

In the given equation y = f(x) and f(x) = 4x-2, the dependent variable is y.

The dependent variable is the output of the function, and its value depends on the value of the independent variable, which is x in this case. So, when we plug in a value for x, we can calculate the corresponding value of y using the function f(x) = 4x-2. Therefore, y is the dependent variable in this equation.

Given statement solution is :- None of the given options (a, b, c, or d) match the meaning of the slope. The correct interpretation is that the car travels approximately 0.8 miles every minute.

To determine the meaning of the slope of the linear model for the given data, let's analyze the information provided. The table represents the distance traveled by a car at different time intervals.

Minutes | Distance Traveled (in miles)

50 | 20

20 | f

40 | 60

100 | a

125 | 80

100 | 100

To find the slope of the linear model, we need to calculate the change in distance divided by the change in time. Let's consider the intervals where the time changes by a fixed amount:

Between 50 minutes and 20 minutes: The distance changes from 20 miles to 'f' miles. We don't have the exact value of 'f', so we can't calculate the slope for this interval.

Between 20 minutes and 40 minutes: The distance changes from 'f' miles to 60 miles. Again, without knowing the value of 'f', we can't calculate the slope for this interval.

Between 40 minutes and 100 minutes: The distance changes from 60 miles to 'a' miles. We don't have the exact value of 'a', so we can't calculate the slope for this interval.

Between 100 minutes and 125 minutes: The distance changes from 'a' miles to 80 miles. Since we still don't have the exact value of 'a', we can't calculate the slope for this interval.

Between 125 minutes and 100 minutes: The distance changes from 80 miles to 100 miles. The time interval is 25 minutes, and the distance change is 100 - 80 = 20 miles.

Therefore, based on the given data, we can conclude that the car travels 20 miles in 25 minutes. To determine the meaning of the slope, we divide the distance change by the time change:

Slope = Distance Change / Time Change

= 20 miles / 25 minutes

= 0.8 miles per minute

So, none of the given options (a, b, c, or d) match the meaning of the slope. The correct interpretation is that the car travels approximately 0.8 miles every minute.

Answer:

S 32, W 128, M 96

Step-by-step explanation:

W = 4S

S = 1/3M, or 3S = M

S + W + M = 256

Substitute

S + 4S + 3S = 256

8S = 256, S = 32

S = 32

W = 4S = 128

M = 3S = 96

The vertex of the graphed function f(x) = [x - 4] + 3 is (4, 3).

The function f(x) = [x - 4] + 3 is in the form of an absolute value function, where the expression inside the absolute value brackets represents the input value shifted horizontally by 4 units to the right.

The constant term of 3 represents a vertical shift upwards by 3 units.

To find the vertex of this function, we need to determine the x-coordinate that corresponds to the minimum value of the absolute value function.

In this case, since the absolute value function is within brackets and not being multiplied or divided by a coefficient, the minimum value occurs at the point where the expression inside the brackets equals zero.

Therefore, setting x - 4 = 0, we find x = 4.

Substituting this x-value into the function, we find f(4) = [4 - 4] + 3 = 3. So the vertex of the graphed function is located at the point (4, 3), where x = 4 and y = 3. This means that the graph is shifted 4 units to the right and 3 units upward from the origin.

The location which is in the region for plants receiving the maximum amount of water is "(-3,-1)". The Option A is correct.

Water flows into the open pore spaces in the soil by gravity, and the size and spacing of the soil particles determine how much water can flow in. Because coarse soils have larger pore spacing at the soil surface, they have a higher infiltration rate than fine soils.

Based on the graph, we observed that the point of location in which is in the region for plants receiving the maximum amount of water is the point (-3,-1). Therefore, we agree that Option A is correct.

All golden rectangles are similar and the ratio length/width = golden ratio = \(\frac{1 + \sqrt{5} }{2}\).

What is golden Rectangle ?

A golden rectangle is a rectangle that can be cut up into a square and a rectangle similar to the original one. More precisely,

Let ABCD be a rectangle, with width AB < length BC. Then there is a point E on segment AD and a point F on segment BC so that BFEA is a square. i.e., AE = BF = AB (and consequently EF = AB also). Then FCDE is a rectangle. We say that ABCD is a golden rectangle if FCDE is similar to ABCD.

Theorem:  All golden rectangles are similar and the ratio length/width = golden ratio = \(\frac{1 + \sqrt{5} }{2}\).

Corollary.  If ABCD is a golden rectangle, so is the sub - rectangle FCDE (as defined below).

Proof:  Let a = AB = width and b = BC = length of a golden rectangle.  Then for ABCD the ratio length/width = b/a and for FCDE the ratio length/width = a/(b-a).  The rectangles are similar if and only if these ratios are equal, so, if we set k = b/a, then b = ka and k = b/a = a/(b-a) = a/(ka – a) = 1/(k-1).

Therefore k is a root of k^2 – k – 1 = 0; also, k is a positive number.  By the quadratic formula the only positive root of this polynomial is the golden ratio \(\frac{1 + \sqrt{5} }{2}\\\).

The probability and binomial distribution are solved and the selected student will need to attend the math class

Given data ,

Let's denote the probability that a randomly selected student still needs to take another math class as "p".

Given that 72% of all students still need to take another math class, we have p = 0.72.

From the binomial distribution , we get

P(X=k) = C(n, k) * p^k * (1-p)^(n-k)

where:

P(X=k) is the probability of exactly k successes in n trials

C(n, k) is the number of ways to choose k items from n items, also known as "n choose k"

p is the probability of success on a single trial

k is the number of successes

n is the total number of trials

Let's use this formula to solve the questions:

a)

Exactly 29 of them still need to take another math class:

Here, k = 29, n = 38, and p = 0.72

P(X=29) = C(38, 29) * 0.72^29 * (1-0.72)^(38-29)

P ( X = 29 ) = 0.1257

b)

Fewer than 27 of them still need to take another math class:

Here, we need to find the probability of having 0, 1, 2, ..., 26 successes, and then add them together:

P(X<27) = P(X=0) + P(X=1) + P(X=2) + ... + P(X=26)

P ( X < 27 ) = 0.5096

c)

More than 25 of them still need to take another math class:

Here, we need to find the probability of having 26, 27, 28, ..., 38 successes, and then add them together:

P(X>25) = P(X=26) + P(X=27) + P(X=28) + ... + P(X=38)

P ( X > 25 ) = 0.7537
