A cow is tied with a rope in the centre of a circular lawn of diameter 28cm.If the length of the rope is 7cm, find the area of the lawn which the cow graze.Also find the remaining area of thelawn.​

One of the equation which illustrates and meets the decimal conditions given is :

1.25 × 0.2 = 0.25

Let the first number  with two decimal places be x = 1.25

Let the second number with one decimal place be y = 0.2

Result = first Number × second number

Thus;

Result = 1.25 × 0.2

Result = 0.25

Evaluating the result of 0.25, it means that;

Number of digits = 3

Non - zero digits = 2

There are several values of x and y which will satisfy the 3 conditions given.

Therefore, the product of the values 1.25 and 0.2 gives the required output of the question.

Answer:

To solve this problem, you can set up an equation using the given information. Let "x" be the number in question.

We are told that 10 more than 32% of x is equal to 26. This can be written as:

10 + 0.32x = 26

To solve for x, you can start by subtracting 10 from both sides of the equation:

10 + 0.32x - 10 = 26 - 10

This simplifies to:

0.32x = 16

To isolate the x term, you can divide both sides of the equation by 0.32:

(0.32x)/0.32 = 16/0.32

This simplifies to:

x = 50

Therefore, the number we are trying to find is 50.

The following series can be classified as

1 + 2 + 4 + 8 ... +..  is divergent series.

200 + 100 + 50 + 25 ... is convergent series

1/2 + 2/3 + 8/9 + 32/27 ... is divergent series.

10 + 5 + 0 - 5 + .... is convergent series

4 - 2 + 1 - 1/2 + .... is convergent series

4 - 8 + 16 - 32 ..... is  convergent series  

If a series converges to a value as its terms approach infinity, it is said to be convergent. Example:

Series of terms which are squares of natural numbers

=> 1, 4, 9, 16, 25.... which goes upto infinity

Hence given series is the Convergent series

If a series does not converge to a value but instead keeps on increasing or dropping as the terms of the series tend to infinitely, it is said to be divergent. Example: 1, 1/2, 1/3, 1/4 ... etc

Where it tends to 0 as the term goes to infinity.  

Note:

If the common ratio lies between (-1, +1), then the series is convergent if it does not lie between (-1, +1) then the series is divergent.

Here given series are

1 + 2 + 4 + 8 ... +

Here common ratio = 2/1 = 2  

Common ratio, 2 > 1

1 + 2 + 4 + 8 ... +..  is divergent series.

200 + 100 + 50 + 25 ...

Common ratio = 100/200 = 1/2

Common ratio, 1/2 < 1

200 + 100 + 50 + 25 ... is convergent series

1/2 + 2/3 + 8/9 + 32/27 ...

Common ratio = 2/3 / 1/2 = 4/3

Common ratio, 4/3 > 1

1/2 + 2/3 + 8/9 + 32/27 ... is divergent series.

10 + 5 + 0 - 5 + ....

Common ratio, 1/2 < 1

10 + 5 + 0 - 5 + .... is convergent series

f(x)=|x+4|-1 with a vertical stretch by a factor of 5, so the translation function becomes: 5|x + 4| - 5.

According to operations like multiplication or sum/subtraction either in its definition or in its domain, a translation is represented by a change in the function graph. Examples include shifting to the left or right or up or down, compressing or extending vertically or horizontally, and reflecting across the x- or y-axis.

For this problem, the function is given by:

f(x) = |x + 4| - 1.

For a vertical stretch by a factor of 5, the function is multiplied by 5, hence the translated function is given by:

The mean, median, and mode 0, 4, 6, 11, 9, 8, 9, 1, 5, 9, 7 are 6.2, 7, and 9.

A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

From the data set:

0, 4, 6, 11, 9, 8, 9, 1, 5, 9, 7

Mean = ( 0+ 4+ 6+11+ 9+ 8+ 9+ 1+ 5+ 9+7)/11 = 6.2

The mean is the middle number(s) in a data set. Hence

Median = 7

The mode is the most occurring number in a data set

Hence,

Mode = 9

Thus, the mean, median, and mode 0, 4, 6, 11, 9, 8, 9, 1, 5, 9, 7 are 6.2, 7, and 9.

Step-by-step explanation:

To find the y-coordinate of point Q, we first need to find the coordinates of point Q. Since points P, Q, and R are collinear and the ratio of PQ to PR is 3/4, we know that the ratio of their x-coordinates and y-coordinates must also be 3/4.

Let's call the coordinates of point Q (x, y). We know that the x-coordinate of point Q is 3/4 of the way between the x-coordinates of points P and R. This means that the x-coordinate of point Q is (3/4) * (-4 - 3) + 3 = -1.

Similarly, the y-coordinate of point Q is (3/4) of the way between the y-coordinates of points P and R. This means that the y-coordinate of point Q is (3/4) * (5 - (-5)) - 5 = 0.

Therefore, the coordinates of point Q are (-1, 0). The y-coordinate of point Q is 0.

The coordinates of point Q are (3, -5), and the y-coordinate of point Q is -5.

Collinear points are points that lie on the same straight line. In other words, if you can draw a straight line through two or more points, then those points are said to be collinear.

Given that the ratio of PQ to PR is 3/4.

Let's assume the coordinates of point Q are (x, y).

Using the midpoint formula, we can find the coordinates of the midpoint M of line segment PR:

M = ((x1 + x2)/2, (y1 + y2)/2)

Substituting the coordinates of points P (3, -5) and R (-4, 5), we have:

M = ((3 - 4)/2, (-5 + 5)/2) = (-1/2, 0)

and, M = ((x + (-4))/2, (y + 5)/2)

Equating the x-coordinates and y-coordinates, we get:

-1/2 = (x - 4)/2 => x - 4 = -1 => x = 3

0 = (y + 5)/2 => y + 5 = 0 => y = -5

Therefore, the coordinates of point Q are (3, -5), and the y-coordinate of point Q is -5.

By using the vertical line test, the relation graphed above is a function. Therefore, the correct answer choice is: A. yes.

In Mathematics, a vertical line test can be defined as a technique which is typically used to determine whether or not a given relation is a function.

According to the vertical line test, a vertical line must cut through the x-coordinate (x-axis) on the graph of a function at only one (1) point, in order for it to represent a function. Else, the relation does not represent a function because it can only have one output value (y) for a unique input value (x).

The value of the function f(g(1)) = 1

A function is a mathematical expression that shows the relationship between two variables.

Consider functions f and g.

f(x) = 3 √x + 1, to determine the value of f(g(1)), we substitute g(x) into the equation for f(x).

So, f(x) = 3 √x + 1

f(g(x)) = 3√x + 1

f(g(x)) = 3√g(x) + 1

So, substititng x = 1, we have that

f(g(1)) = 3√g(1) + 1

We see that from the table g(1) = 0.

So, susbtituting the values of the variables into the equation, we have that

f(g(1)) = 3√g(1) + 1

f(g(1)) = 3√0 + 1

The lines are perpendicular because the product of their slopes is -1

The slope-intercept form of the equation of a straight line is:

y = mx + c,

where m is the slope and c is the y-intercept

When two lines are perpendicular, the product of their slope is -1 i.e.

m₁ × m₂ = -1

where m₁ and m₂ represent the slope of the lines

But when two lines are parallel, they have the same slope i.e.

m₁ = m₂

Let's examine the equations:

y-3=4(x+4) and x+4y=16

First write the equations in slope-intercept form. That is:

y-3 = 4(x+4)

y-3 = 4x+16

y = 4x+16+3

y = 4x+19   (slope, m = 4 )

x+4y = 16

4y = -x + 16

y = (-1/4)x + 4   (slope, m = -1/4 )

Since the slopes of the lines are not the equal, they are not parallel.

Since the product of the slopes of the line is -1 (i.e. 4 × -1/4 = -1), they are perpendicular.
