The father is with the son's mother.

Given that,

a mother is 21 years older than her son.

Let us consider M be the age of the mother and S be the age of the son

which implies that,

M = S + 21 ---------------(1)

and in 6 years, mother will be 5 times as old as her son

i.e. M + 6 = 5(S + 6)

M = 5S + 24 ------------- (2)

so equation (1) and (2) implies that,

S + 21 = 5S + 24

     21 = 4S + 24

       S = - 3/4

Answer: y = -3/5x - 6

Step-by-step explanation:

There are a few equations that can be used for this, but the simplest one would be y = mx + b

We are given:

y = -3

m = -3/5 (slope)

x = -5

b = ?

Our equation is this, we are solving for b

==> -3 = -3/5 ( -5) + b

==> -3 = -3/5 ( -5) + b ( multiply the brackets)

==> -3 = 3 + b ( subtract 3 to both sides)

==> -6 = b

Now we can make the desired equation in slope intercept form;

y = -3/5x - 6

Reflection

Step-by-step explanation:

With a reflection, a shape is mirrored across a line. So, while its position is changed, the points end up getting flipped too. In this problem, you can imagine a diagonal line goes right through the center of the two shapes shown (the original and its mirror). The line would be equidistant from L and G; it would be equidistant from B and D; it would also be equidistant from U and O. If you were to mirror B, U, and L across this line, you would get your reflection points D, O, and G.

Arima model fits this pattern of autocorrelations is ARIMA(5,0,0).

The Autoregressive Integrated Moving Average (ARIMA) is an acronym that stands for the Autoregressive Integrated Moving Average model.

It is a statistical model for time series data that describes the correlation between points in a time series and provides insights into the temporal behavior of a variable.

The ARIMA model is a forecasting technique that uses time series data to make predictions. It is widely used in finance, economics, and other fields where it is necessary to predict the future behavior of a variable.

ARIMA models have the advantage of being able to capture trends, seasonality, and other patterns that can be difficult to detect using other methods.

The ARIMA model is made up of three parts:

the autoregressive (AR) component, the integrated (I) component, and the moving average (MA) component. The AR component takes into account the relationship between the current observation and the previous observations.

The I component deals with the trend and seasonality of the data. The MA component takes into account the relationship between the current observation and the previous errors.

For the series of length 169, we find that r1 = 0.41, r2 = 0.32, r3 = 0.26, r4 = 0.21, and r5 = 0.16. The ARIMA model that fits this pattern of autocorrelations is ARIMA(5,0,0), which means that there are five autoregressive terms in the model and no moving average or integrated terms are needed.

Answer:

Balanced Force

Step-by-step explanation:

A balanced force.  There is no movement with respect to the forces.

We can start by finding the time it takes for Gill to travel the first 27km:

Time taken = Distance / Speed = 27km / 96 km/h = 0.28125 hours

Next, we need to account for the 3-minute stop in Lens. Since 1 hour has 60 minutes, 3 minutes is 3/60 = 0.05 hours.

The total time taken for the journey from the start to Lens is:

0.28125 hours + 0.05 hours = 0.33125 hours

Now we need to find the time it takes for Gill to travel the final 29km:

Time taken = Distance / Speed = 29km / 96 km/h = 0.30208 hours

Adding the time taken for the first part of the journey to the time taken for the second part gives the total time taken for the journey:

0.33125 hours + 0.30208 hours = 0.63333 hours

Finally, we can add this time to the departure time of 09:00 to find the arrival time:

09:00 + 0.63333 hours = 09:38 (rounded to the nearest minute)

ANSWER IS B

Okay, here are the steps to solve this problem:

1) Gill leaves Lille by train at 09:00.

2) The train travels 27km at 96km/h. 27km / 96km/h = 0.2833h = 17min

3) So the train will arrive at Lens at 09:17 (09:00 + 17min)

4) The train stops at Lens for 3 minutes. 3min = 0.05h

5) So the train leaves Lens at 09:22 (09:17 + 3min = 0.05h)

6) The train then travels 29km at 96km/h. 29km / 96km/h = 0.3021h = 18min

7) So the train will arrive at Lillers at 09:40 (09:22 + 18min)

Therefore, the answer is C 09:40

Step 1: The greatest common factor (GCF) in this equation is x^3. So we can factor it out:

y = x^3(x - 343)

What does a math equation mean?

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.

Step 2: We can not take root of a³ and b as there is no square term in the equation.

Step 3:

a= x^3

b= - 343

Step 4: Plugging in a and b into the original equation, we get

y = x^3(x - 343)

This is the simplified form of the equation.

So, the equation is a polynomial equation of degree 4, with the leading coefficient a = x^3 and the constant term b = -343, and it can be written as y = a(x-b) which is y = x^3(x-343)

No, it is not possible to define f(0) in a way that makes f continuous at 0.

To see why, let's consider the behavior of f(x) as x approaches 0. We have:

lim x → 0 x sin(1/x)

Now, since -1 ≤ sin(1/x) ≤ 1 for all x, we have:

x ≤ x sin(1/x) ≤ x for all x

Therefore, by the squeeze theorem, we have:

lim x → 0 x sin(1/x) = 0

This means that the limit of f(x) as x approaches 0 exists and is equal to 0.

However, if we try to define f(0) to make f continuous at 0, we run into a problem. If we choose any value for f(0), say a, then the function is not continuous at 0 because the limit from the left is not equal to the limit from the right.

To see this, consider the left-hand limit of f(x) as x approaches 0:

lim x → 0- f(x) = lim x → 0- x sin(1/x)

We can use the substitution u = 1/x to rewrite this as:

lim u → -∞ (-1/u) sin u

Now, we know that the sine function oscillates between -1 and 1 as its input approaches -∞, so the limit of this expression does not exist. Therefore, the left-hand limit of f(x) as x approaches 0 does not exist.

Similarly, we can show that the right-hand limit of f(x) as x approaches 0 does not exist.

Therefore, it is not possible to define f(0) in a way that makes f continuous at 0.

The chance that the hospital will run out of sleeping pills on any given day is 0.5000 (or 0.5000 with four decimal places).

To calculate the chance that the hospital will run out of sleeping pills on any given day, we can use the normal distribution and Z-score.

First, let's calculate the Z-score using the formula:

Z = (X - μ) / σ

Where:

X = consumption rate per day (1,155 pills)

μ = average consumption rate per day (1,155 pills)

σ = standard deviation (81 pills)

Z = (1,155 - 1,155) / 81

Z = 0

Now, we need to find the probability associated with this Z-score. However, since the demand for sleeping pills can be considered continuous and not discrete, we need to calculate the area under the curve from negative infinity up to the Z-score. This represents the probability of not running out of sleeping pills.

We discover that the region to the left of a Z-score of 0 is 0.5000 using a basic normal distribution table or statistical software.

To find the probability of running out of sleeping pills, we subtract this probability from 1:

Probability of running out of sleeping pills = 1 - 0.5000

Probability of running out of sleeping pills = 0.5000

Therefore, on any given day, the hospital has a 0.5000 (or 0.5000 with four decimal places) chance of running out of sleeping tablets.

Corresponding and Congruent

Step-by-step explanation:

If point C is on the circle with diameter AB, then triangle ABC must be a right triangle. This is because the diameter of a circle is the longest chord and it passes through the center of the circle.

If we draw a line from point C to the center of the circle (which is the midpoint of AB), we get a perpendicular bisector of AB, meaning that it cuts AB into two equal parts and forms right angles with it. This also means that AC and BC are equal in length (since they both form radii of the circle), and the angle at point C must be a right angle (since it forms a straight line with the center of the circle). Thus, triangle ABC satisfies the criteria for a right triangle.

In summary, if point C lies on the circle with diameter AB, then triangle ABC must be a right triangle with AC and BC as its legs and AB as its hypotenuse. This is a fundamental property of circles and right triangles, and it is important to understand in order to solve various geometry problems involving circles and triangles.

A line segment known as a perpendicular bisector divides a straight line segment into two congruent or equal pieces. At the exact midway of the line segment, they divide it. A perpendicular bisector turns the line segment it bisects 90 degrees.

A line that precisely divides a line segment connecting two locations in half at a 90 degree angle is known as a perpendicular bisector. Finding the midpoint and negative reciprocal of two points, then entering these solutions into the equation for a line in slope-intercept form, will get the perpendicular bisector of the two points.

The need for determining the perpendicular line is coordinates and a line equation. Think about a line with the equation axe + by + c = 0 and the coordinates (x1, y1). The slope should be a/b. The slopes should add up to -1 if one line is perpendicular to this one.
