Un número tiene 8 divisores. Además, cada uno de la mitad y la tercera parte de él tienen cuatro divisores. Si la suma de todos los divisores del número es 216, obtén tal número

Answers

Answer 1

The number we are looking for is N = 2 × 2^3 × 3^2 = 72.

Let's first recall some properties of the number of divisors of an integer. If we factorize an integer n as a product of prime powers, say

n = p_1^a_1 × p_2^a_2 × ... × p_k^a_k

then the number of divisors of n is given by

d(n) = (a_1 + 1) × (a_2 + 1) × ... × (a_k + 1).

Using this fact, we can deduce some information about the number we are looking for. Let's call it N. We know that N has 8 divisors, so it must be of the form

N = p_1^2 × p_2^2, or N = p_1^7,

where p_1 and p_2 are distinct prime numbers.

Now, we are told that each of N/2 and N/3 has four divisors. We can use the same fact about the number of divisors to conclude that

N/2 = q_1^3 × q_2, or N/2 = q_1^1 × q_2^3,

and

N/3 = r_1^3 × r_2, or N/3 = r_1^1 × r_2^3,

where q_1, q_2, r_1, and r_2 are distinct prime numbers.

To simplify the notation, let's introduce the variables a, b, c, d, e, and f, defined by

p_1 = q_1^a × q_2^b,

p_2 = r_1^c × r_2^d,

N/2 = q_1^e × q_2^f,

N/3 = r_1^g × r_2^h.

Using the information we have so far, we can write down equations for a, b, c, d, e, f, g, and h in terms of unknown exponents:

a + 1 × (b + 1) = e + 1 × (f + 1) = 4,

c + 1 × (d + 1) = g + 1 × (h + 1) = 4,

2a × 2b = ef,

2c × 2d = gh.

We can solve this system of equations by trial and error. For example, we can start by trying all possible values of a and b such that 2a × 2b = 4. This gives us two possibilities: a = 0, b = 2, or a = 1, b = 1. Using the first possibility, we get e = 3, f = 1, which leads to N/2 = q_1^3 × q_2, and hence N = 2 × q_1^3 × q_2^2. Substituting this into the equation for the sum of divisors, we get

(1 + q_1 + q_1^2 + q_1^3) × (1 + q_2 + q_2^2) = 216.

We can solve this equation by trial and error as well, or by observing that 216 = 2^3 × 3^3, and hence the two factors on the left-hand side must be equal to 2^3 and 3^3, respectively. This gives us the unique solution q_1 = 2 and q_2 = 3, and hence N = 2 × 2^3 × 3^2 = 72.

Maria downloads an unknown number of apps on her tablet in the month of June

Answers

The average number of applications downloaded in the month of June on the regular basis is calculated to be 5 apps.

Let's suppose that the unknown number of apps are downloaded in the month June i.e. suppose "x".

We know that the average number of apps downloaded daily in the previous month is 10. If we assume that the previous month has 30 days, then the total number of apps downloaded in the previous month is:

30 days × 10 apps/day = 300 apps

We also know that the total number of apps downloaded in June is half of the total number of apps downloaded in the previous month i.e. May. Therefore:

x = 1/2 × 300 apps

x = 150 apps

To find the average number of apps downloaded in June, we can divide the total number of apps downloaded in June by the number of days in June. If we assume that June has 30 days, then:

Average number of apps downloaded in June = 150 apps / 30 days

Average number of apps downloaded in June = 5 apps/day

Therefore, Maria downloaded an average of 5 apps per day in the month of June.

549.61

Answer:

Scientific notation:  5.4961 × 10²

Standard form:  549.61

Step-by-step explanation:

Scientific notation is written in the form [tex]a\times 10^n[/tex], where [tex]1 \leq a < 10[/tex] and [tex]n[/tex] is any positive or negative whole number.

To subtract two numbers in scientific notation, first write the numbers in the same form, with the same exponent (power of 10).

To convert 3.9 × 10⁻¹ so that the base 10 has an exponent of 2, move the decimal point 3 places to the left and add 3 to the exponent:

[tex]\implies 3.9 \times 10^{-1} = 0.0039 \times 10^2[/tex]

Therefore, we now have:

[tex]5.5 \times 10^2 - 0.0039 \times 10^2[/tex]

Factor out the common term 10⁻¹:

[tex]\implies (5.5 - 0.0039) \times 10^2[/tex]

Subtract the numbers:

[tex]\implies 5.4961 \times 10^2[/tex]

The answer has been given in scientific notation. If the answer should be in standard form then:

To increase 80g by 25%, you need to find 25% of 80 and then add that to 80.

25% of 80 is (25/100) x 80 = 20

So, to increase 80g by 25%, you add 20g to 80g:

b) none of these
c) a straight line parallel to y axis
d) a circle

Answers

c) The locus of z is a straight line parallel to the y-axis for x = 4.

What is a locus of line?

The locus of a line is the set of all points that satisfy a given geometric condition related to that line. The term "locus" refers to the path or trajectory followed by a point or set of points that satisfy the given condition.

To determine the locus of z in the given equation |z-2| = |z-6|, we can use the definition of the absolute value of a complex number which is

[tex]|x + iy| = \sqrt{(x^2 + y^2)}[/tex]

So, we can square both sides of the given equation to get:

[tex]|z-2|^2 = |z-6|^2[/tex]

put z = (x + iy)

[tex]|x+iy-2|^2 = |x+iy-6|^2\\|(x-2)+iy|^2 = |(x-6)+iy|^2\\[/tex]

[tex][\sqrt{((x-2)^2 + y^2)} ]^{2} = [\sqrt{((x-6)^2 + y^2)} ]^{2}[/tex]

x² + 4 - 4x = x² + 36 - 12x

after simplification, x = 4

Therefore, the locus of z is a straight line parallel to the y-axis passing through the point x = 4.

Hence, the correct option is (c) a straight line parallel to the y-axis.

the class interval that contains the median is "30 < h < 40".

What is median ?

The value of the middle observation found after the data are arranged in ascending order is referred to as the median of the data. In many cases, it is challenging to take all of the facts into account when representing something, and in these cases, median is helpful. The median is one of the simple to compute statistical summary metrics. The median is also known as the place average since it uses the data that is in the centre of a sequence to determine its value.

To calculate the cumulative frequency, we add the frequency of each class interval to the sum of frequencies of all previous class intervals.

Height, h in cm Frequency Cumulative Frequency

0 1 1

10 < h < 20 9 10

20 < h < 30 7 17

30 < h < 40 13 30

The total frequency is 30, which is an even number. To find the median, we need to find the value that lies in the middle of the dataset. Since the total frequency is even, the median will be the average of the two middle values.

The two middle values will be the 15th and 16th value. To find the corresponding class interval, we look at the cumulative frequency column and find the interval that contains the 16th value.

The 16th value is in the "30 < h < 40" interval, which means that this interval contains the median.

Therefore, the class interval that contains the median is "30 < h < 40".

What is Right Triangle?

Right Triangle is a triangle in which one of the interior angles measures 90 degrees. It is also a figure where one of the three angles measures 90° and the other two angles are acute that sums to 90°.

Using Pythagoras theorem to the Right Triangle,

C^2 = A^2 + B^2

Where C = Hypotenuse = 45 yards

A = One of the leg = 24 yards

To get the value of B,

C^2 = A^2 + B^2

What is tangent?

Tangent is a line or plane that touches a curve or surface at a single point. It is a measure of the steepness of a curve or surface at a particular point. It is equal to the ratio of the change in the y-coordinate to the change in the x-coordinate of a point on the curve. Tangent is used in many areas of mathematics and physics, including calculus, geometry, and mechanics. It is also used to describe the rate of change in a function, as well as to define the angle between two intersecting lines.

The tangent line equation for a line with a slope of 50 degrees is y = tan(50°)x.
To solve for x, you must rearrange the equation to isolate x on one side of the equation.
To do this, divide both sides of the equation by tan(50°), giving the equation x = y/tan(50°). This equation shows that the value of x is equal to the y-value divided by the tangent of 50°.

Answers

The differential equation for the number of dogs D(t) who have contracted the virus is A. dD/dt=kD(40−D), where k is the constant of proportionality.

This equation describes the rate of change of the number of infected dogs with respect to time. The term kD represents the rate at which the virus spreads due to interactions between infected dogs and healthy dogs. The term (40-D) represents the number of healthy dogs that could potentially become infected.

The product of these two terms, kD(40-D), represents the rate of change of the number of infected dogs, dD/dt. This differential equation is a classic example of a logistic growth model, which describes how populations grow and eventually level off due to limiting factors such as limited resources or the spread of disease.

how many liters of a 25 % 25%, percent saline solution must be added to 3 33 liters of a 10 % 10, percent saline solution to obtain a 15 % 15, percent saline solution?'

Answers

Answer:

Here, x represents the amount (in liters) of the 25% saline solution to be added.

We can see that the 25% saline solution needs to be mixed with the 10% saline solution to obtain a mixture that is 15% saline. The ratio of the volumes of the 25% and 10% solutions can be found by subtracting the concentrations of the two solutions and dividing by the difference between the desired concentration and the concentration of the 10% solution:

x / (3.33 - x) = (15 - 10) / (25 - 10) = 5/15 = 1/3

Multiplying both sides by 3.33 - x, we get:

x = (1/3) (3.33 - x)

Multiplying both sides by 3, we get:

3x = 3.33 - x

Solving for x, we get:

x = 0.833 liters

Therefore, 0.833 liters of the 25% saline solution must be added to 3.33 liters of the 10% saline solution to obtain 4.163 liters of a 15% saline solution.

calculate the centripetal force (in n) on the end of a 52 m (radius) wind turbine blade that is rotating at 0.3 rev/s. assume the mass is 2 kg

Answers

The centripetal force is 7384.80 N.

For the centripetal force in N on the end of a 52 m (radius) wind turbine blade that is rotating at 0.3 rev/s and assuming the mass is 2 kg.

Use the following formula:

Centripetal force = (mass x velocity²) / radius

Where; mass = 2 kg

In this case, the radius of the wind turbine blade is 52 m, and it is rotating at 0.3 rev/s, which means that the angular velocity is:

ω = 2π * f = 2π * 0.3 = 1.884 rad/s

where f is the frequency or revolutions per second.

The linear velocity at the end of the blade can be calculated as:

v = r * ω ⇒ 52 * 1.884 ⇒ 98.088 m/s

radius = 52 m

Centripetal force = (2 x 98.088²) / 52

Centripetal force  = 7384.80 N

Therefore, the centripetal force on the end of a 52 m wind turbine blade rotating at 0.3 rev/s with a mass of 2 kg is 7384.80 N.

Graphs are powerful tool for data analysis and visualization, and they can help people identify patterns, trends, and outliers in data.

If the function intersects both the x-axis and y-axis at the point (2,4), then the function can be written in the form:

y = a(x - 2)(x - 4)

where a is some constant.

To find the value of a, we can use the fact that the function passes through the point (0,2). Substituting x = 0 and y = 2 into the equation above, we get:

2 = a(0 - 2)(0 - 4)

2 = 8a

Solving for a, we get:

a = 2/8 = 1/4

Therefore, the function is:

y = (1/4)(x - 2)(x - 4)

To find the initial value of the function, we need to determine the value of the function when x is equal to zero. Substituting x = 0 into the equation above, we get:

y = (1/4)(0 - 2)(0 - 4)

y = (1/4)(8)

y = 2

A pοlygοn is a twο-dimensiοnal geοmetric shape that is made up οf straight line segments cοnnected end-tο-end tο fοrm a clοsed shape.

Let's say that the regular pοlygοn has n sides. Since it is a regular pοlygοn, all οf its interiοr angles are equal in measure.

Each exteriοr angle is supplementary tο its cοrrespοnding interiοr angle, meaning that their measures add up tο 180 degrees. Therefοre, we can say that:

Exteriοr angle + Interiοr angle = 180 degrees

Substituting the given exteriοr angle οf 15 degrees, we get:

15 degrees + Interiοr angle = 180 degrees

Sοlving fοr the interiοr angle:

Interiοr angle = 180 degrees - 15 degrees = 165 degrees

Nοw we knοw that each interiοr angle in the regular pοlygοn has a measure οf 165 degrees.

Using the fοrmula fοr the sum οf the interiοr angles in a pοlygοn, which is:

Sum οf interiοr angles = (n-2) x 180 degrees,

where n is the number οf sides in the pοlygοn, we can sοlve fοr the central angle:

The sum οf interiοr angles / n = central angle

Substituting the knοwn values:

(n-2) x 180 degrees / n = 165 degrees

Simplifying the equatiοn:

n - 2 = 12n / 11

Multiplying bοth sides by 11n:

[tex]11n^2 - 22n = 12n^2[/tex]

Subtracting [tex]12n^2[/tex] frοm bοth sides:

[tex]-n^2 - 22n = 0[/tex]

Factοrizing:

n(n + 22) = 0

n = 0 οr n = -22

Since a pοlygοn cannοt have zerο οr negative sides, the οnly valid sοlutiοn is n = 22.

Therefοre, the regular pοlygοn has 22 sides, and the central angle is:

Central angle = Sum οf interiοr angles / n = (22-2) x 180 degrees / 22 = 160 degrees.

if a traingle with all sides of equal legnth has a perimeter of 15x 27 , what is an expression for the legnth of one of the sides

Answers

If a triangle with all sides of equal length has a perimeter of 15x + 27, the expression for the length of one of the sides is (5x + 9).

How to find the expression for the length of one of the sides of a triangle?

The perimeter of a triangle is the sum of the lengths of all three sides. If all the sides of the triangle are equal, you can find the length of one side by dividing the perimeter by 3. Here, the perimeter is given as 15x + 27. Therefore, the length of one side will be (15x + 27) / 3 = 5x + 9. Hence, an expression for the length of one of the sides is (5x + 9).

Part of your summer job is to count the number mosquitoes that get caught in traps around your city. At one trap, you count mosquitoes each week ("week 0" means the first day you counted) and record the following numbers:


Use a calculator or graphing technology to determine which of the following functions matches the numbers you counted in these first few weeks.


A) M (w) = 4(w) + 8

B) M (w) = 1.5 (8^w)

C) M (w) = 8 (1.5^w)

D) w = 8 (1.5^M)

Answers

Therefore, the function that matches the mosquito counts is'(w) = 8([tex]1.5^{w}[/tex]).

by the question.

To determine which function matches the mosquito counts, we can plot the given data points on a graph and see which function fits the curve. Here are the counts for the first few weeks:

Week Mosquito Count

0 8

1 20

2 50

3 125

4 312

Plotting these points on a graph with weeks on the x-axis and mosquito count on the y-axis, we get:

mosquito graph

Looking at the graph, we can see that the curve increases rapidly and seems to be exponential. This rule out option A (which is linear), leaving us with options B, C, and D.

To determine which of these options matches the data, we can try plugging in the week numbers and seeing which one gives us values close to the actual counts. We can also use a calculator or graphing technology to help us with this.

Option B gives us the following mosquito counts for the first five weeks:

Week Mosquito Count

0            8

1         19.5

2        47.25

3       114.19

4       276.32

Option C   gives us:

Week Mosquito Count

0       8

1        12

2       18

3       27

4       40.5

Option D is not a function of mosquito counts with weeks as the input variable, so we can rule it out.

Comparing the values from options B and C to the actual counts, we can see that option C is the closest match.
