Why will the speedup of a parallel algorithm will eventually reach some limit?

Answers

Answer 1

The advantages of adding additional processors will decrease as more are added because some portions are always still sequential, and eventually the speedup approaches a limit.

What is a parallel algorithm's speedup factor?

The ratio of the compute time for the sequential method to the time for the parallel algorithm represents the speedup of a parallel algorithm over a matching sequential algorithm. n-fold speedup is what we refer to if the speedup factor is n. For instance, if a sequential approach needs 10 minutes to compute while a parallel algorithm needs just 2, then the speedup is 5 times.

The observed speedup is dependent on every aspect of the implementation. For instance, more processors frequently result in speedups that are greater; but, if other programmer are running on the processors concurrently with a programmer using a parallel technique, the speedup may be reduced by those other applications.

Answers

The best method of collecting a population sample so that the commuter can answer this question is C. Look up a number of randomly selected gas stations in the area to find out gas prices.

What is the population?

The entire group about which you want to draw conclusions is referred to as a population. The particular group from which you will gather data is known as a sample. The sample size is always smaller than the total population size.

A sample is characterized as a more manageable and compact version of a larger group. a smaller population that possesses the traits of a larger population. When the population size is too large to include all participants or observations in the test, a sample is used in statistical analysis.

This method would be the most representative of the entire population of gas stations in the area, and therefore the most likely to produce an accurate average price.

The inequality is x 26 and asks for the values of x where the perimeter of the rectangle is smaller than 112.

The definition of inequality

In mathematics, a link between two terms or values that isn't comparable is referred to as an inequality. As a result, imbalance leads to inequality. A mathematical inequality is a relationship between two non-equal expression . Egality is distinct from inequality. The not common basic is frequently used to denote that two values aren't actually equal (). Various inequalities are used to contrast the values, no matter how small or large. Many simple inequalities can be resolved by switching the two aspects until the variables are the only thing remaining. But a number of things encourage inequality: Values that are negative are divided or added along either side.

Here,

given

A rectangle's perimeter is determined by its length, width, and height.

rectangle's perimeter is calculated as length + length + width + width.

(x +4) + (x+4) + x + x < 112

x + 4 + x + 4 + x + x < 112

4x + 8 < 112

4x < 104

x < 26

In order to find the x value that occur when the rectangle's boundary is less than 112, the inequality is x 26.

What is a proportion?

A proportion is an equation that states that two ratios are equal. It can be written in the form of a/b = c/d. The two ratios, a/b and c/d, are called the terms of the proportion.

The cross-products of a proportion are also equal, so ad = bc.

To solve for d in the equation 5/1.5 = 50/d, you can start by multiplying both sides of the equation by 1.5 to cancel out the denominator on the left side. This gives:

5 = 50/d * 1.5

Next, you can simplify the right side of the equation by multiplying 50 and 1.5, which gives:

5 = 75/d

To solve for d, you can now cross-multiply to get:

75 = 5d

Finally, you can divide both sides of the equation by 5 to get:

d = 75/5

d = 15

the value of d is 15.

Hence, the depth of water from the shore is 15 feet.

ADEF has coordinates D(2, 0), E(3, 3), and F(4, 1). What are the coordinates of AD E F if the original triangle is dilated by a scale factor of 4?​

Answers

Option C is correct. The coordinates of ADE'F' after dilation by a scale factor of 4 are A'(8,0), D'(8,0), E'(12,12), and F'(16,4).

What are coordinates?

Using one or more numbers, or coordinates, a coordinate system in geometry establishes a unique way to locate points or other geometrical objects on a manifold, such Euclidean space. The order of the coordinates is important, and they can sometimes be distinguished by their place in an ordered tuple or by a letter, such as "the x-coordinate." In simple mathematics, the coordinates are assumed to be real numbers, while they could also be complex numbers or components of a more abstract structure, such a commutative ring. Analytic geometry is based on the usage of coordinate systems, which make it possible to convert geometry-related problems into numerical problems and vice versa.

Yes, the rate 4.8 laps every 8 minutes; 3.6 laps every 6-minute form a proportion.

A proportion is an equation that sets two ratios at the same value. For instance, you might express the ratio as follows:

1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4)

4.8 lap every 8 minutes will be equal to (4.8/8) = 0.6 lap a minute.

3.6 lap every 6 minutes will be equal to (3.6/6) = 0.6 lap in a minute.

Here, as the value of the ratio of both the quantities are same so the given values are said to be in Proportion.

How to find the missing segment lengths?

Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.

In ΔACD,

sin 45° = CD/20     (sin = opp/hyp)

(√2)/2 = CD/20

CD = (√2)/2 × 20

CD = 10√2

cos 45° = AC/20   (cos = adj/hyp)

(√2)/2 = AC/20

AC = (√2)/2 × 20

AC = 10√2

In ΔABC,

sin 45° = BC/10√2     (sin = opp/hyp)

(√2)/2 = BC/10√2

BC = (√2)/2 × 10√2

BC = (10 × 2)/2

BC = 10

cos 45° = AB/10√2   (cos = adj/hyp)

(√2)/2 = AB/10√2

AB = (√2)/2 × 10√2

AB = 10

Part AWrite an algebraic description of the transformation of BK.

Part B: What are the endpoints of the new line segment?

Answers

The algebraic description of the transformation of B(x, y) = B'(y + 0, 0 - x)

The algebraic description of the transformation of K(x, y) = K'(y + 0, 0 - x)

The endpoints of the new line segment are B'(4, -1) and K'(-3, -4).

As per the given data BK has endpoints B(1, 4) and K(4, -3).

Rotate BK clockwise 270 degrees about the origin.

Every point of a source image is transformed in a plane via a rotation that rotates it around a fixed point at a specific angle and direction. The fixed point is referred to as the rotational center.

The term "angle of rotation" refers to the rotation's amount and is expressed in degrees.

Rotating a figure 270 degrees clockwise is the same as rotating a figure 90 degrees anticlockwise.

Now, it would be (x, y) = (-y, x)

We have;

R (x, y) to R' (y, -x)

The algebraic description is simply written as;

R (x, y) = R'(y + 0, 0 - x)

B (x, y) = B'(y + 0, 0 - x)

K (x, y) = K'(y + 0, 0 - x)

To get the new endpoints, we simply write the transformation as shown;

B(1, 4) becomes B'(4, -1)

K(4, -3) becomes K'(-3, -4)

Answers

Answer:

La cantidad de días para mantener una población de cerdos mayor en 40 % es de 10 días.

Step-by-step explanation:

Para una misma cantidad de alimentos, el tiempo de duración de los alimentos ([tex]t[/tex]) es inversamente proporcional a la cantidad de cerdos ([tex]c[/tex]), es decir:

[tex]t \propto \frac{1}{c}[/tex]

[tex]t = \frac{k}{c}[/tex] (1)

Donde [tex]k[/tex] es la constante de proporcionalidad, en días.

Podemos eliminar esa constante mediante la siguiente relación:

[tex]\frac{t_{1}}{t_{2}} = \frac{c_{2}}{c_{1}}[/tex] (2)

Si sabemos que [tex]t_{1} = 14\,dias[/tex], [tex]c_{1} = 40[/tex] and [tex]c_{2} = 56[/tex], entonces la cantidad de días asociada una población de cerdos mayor en 40 % es:

[tex]t_{2} = t_{1}\times \frac{c_{1}}{c_{2}}[/tex]

[tex]t_{2} = 14\,dias \times \frac{40}{56}[/tex]

[tex]t_{2} = 10\,dias[/tex]

La cantidad de días para mantener una población de cerdos mayor en 40 % es de 10 días.

In the arrangement below, each number is the non-negative difference of the two numbers above it. What is the sum of the four greatest distinct possible values for $z$

Answers

The numbers in the arrangement can be represented by x, y, z, a, b, c and d, where x is at the top and d is at the bottom. The relationship between the numbers is as follows:

x = y - z

y = a - b

z = c - d

We can use this information to find the values of z, c, and d in terms of x, y, and a:

z = y - x

c = z + d

d = z - c

Since we are looking for the four greatest distinct possible values for z, we can assume that x, y, and a are as small as possible (i.e. 0) and c and d are as large as possible.

Thus, the four greatest distinct possible values for z are:

z = y - x = 0 - 0 = 0

z = a - y = 0 - 0 = 0

z = c - d = c

z = c - d = d

The sum of these four values is 0 + 0 + c + d = c+d.
