What is the segment ratio formula?

P=(m+nmx2​+nx1​​,m+nmy2​+ny1​​). The formula can be derived by constructing two similar right triangles, as shown below. Their hypotenuses are along the line segment and are in the ratio m : n m:n m:n.

A ratio compares two quantities named as antecedent and consequent, by the means of division. For example, when we cook food, then each ingredient has to be added in a ratio. Thus, we can say, a ratio is used to express one quantity as a fraction of another quantity.

Two ratios are equivalent to each other if one of them can be expressed as the multiple of the other. Hence, to get the equivalent ratio of another ratio, we have to multiply the two quantities (antecedent and consequent) by the same number.

Given ratios are 2:1 and 3:1

we can write it as 2/1 and 3/1.

The lcm of 2 and 3 is 6.

Multiply denominator of both ratio with 6, we get

2/6 and 3/6 And we can see both the ratios are not equal.

Hence, there are not equivalent ratios.

4:1 and 8:3 are equivalent ratios -----> is false, because 4:1 is equivalent to 8:2

11:2 and 2:11 are equivalent ratios------> is false (because, are reciprocal ratios, not equivalent ratios)

3:1 and 9:3 are equivalent ratios ------> is true

because 3:1 multiply both sides by 3 -----> 3*3:1*3=9:3

The equation of the circle with center (3, 2) and point (1, 1) is:

(x - 3)² + (y - 2)² = 5.

The equation of a circle with center (h, k) and radius r is given by the equation: (x - h)² + (y - k)² = r²

To find the equation of the circle with center (3, 2) and a point on the circle (1, 1), we first need to find the radius of the circle. We can use the distance formula to find the distance between the center and the point on the circle:

r = √((1 - 3)² + (1 - 2)²) = √((-2)² + (-1)²) = √5

So the radius of the circle is √5

Now we can substitute the center and radius into the equation of a circle:

(x - 3)² + (y - 2)² = (√5)²

Simplifying, we get:

(x - 3)² + (y - 2)² = 5

A controlled experiment is a scientific test conducted under controlled conditions. That is, change only one (or a few) factors at a time and keep all others constant.

Control Experiment:

Controls eliminate alternative explanations for experimental results, particularly experimental error and experimenter bias. Many controls, like molecular markers used in SDS-PAGE experiments, are specific to the type of experiment being performed and may simply have the purpose of confirming that the instrument is functioning properly. I have. Choosing and using appropriate controls and ensuring that experimental results are valid (eg, no confounding variables) can be very difficult. Control measurements can also be used for other purposes. For example, measuring the background noise of a microphone in the absence of a signal allows the noise to be subtracted from later signal measurements to produce a higher quality processed signal.

For example, if a researcher fed a laboratory artificial sweetener to 60 laboratory rats and observed that 10 of them subsequently became ill, the underlying cause could be the sweetener itself or could be something else. Other variables that may not be immediately apparent can interfere with experimental design. For example, an artificial sweetener can be mixed with a diluent, and it could be the diluent that causes the effect.To see the effect of the diluent, he does the same test twice. A diluent with artificial sweeteners and a diluent-only version in the same way. Here the experiment is checked for diluent and the experimenter can distinguish between sweetener, diluent and no treatment. Controls are usually required when confounding factors cannot be easily separated from the primary treatment. For example, a tractor may need to be used to spread manure when there is no other practical way to spread it. The simplest solution is for the tractor to drive over the plot without spreading fertilizer and control the effects of tractor traffic.

The simplest types of controls are negative and positive controls, both of which are found in many different types of experiments. If both are successful, these two controls usually have the most latency. sufficient to eliminate significant confounding variables. That is, an experiment produces a negative result when a negative result is expected and a positive result when a positive result is expected.

The equation P = -0.02n^2 + 3.4n - 16 represents the profit, P, in thousands of dollars for a small independent movie company as a function of the number of DVD copies produced, n, in thousands.

The equation is a quadratic equation, which means it is a polynomial equation of degree 2. The general form of a quadratic equation is ax^2 + bx + c = 0, where a, b and c are constants and x is the variable. In this case, the equation can be written as P = -0.02n^2 + 3.4n - 16, where P is the variable, and -0.02, 3.4, and -16 are the constants.

The first term in the equation is -0.02n^2, which represents the cost of producing the DVD copies. As n increases, the cost of production also increases, and the coefficient -0.02 represents that the cost of production is directly proportional to n^2. The negative sign in front of the term indicates that as the number of copies increases, the cost of production also increases and thus the profit decreases.

The second term in the equation is 3.4n, which represents the revenue generated by the sale of the DVD copies. As n increases, the revenue generated also increases, and the coefficient 3.4 represents that the revenue is directly proportional to n. The positive sign in front of the term indicates that as the number of copies increases, the revenue generated also increases and thus the profit increases.

The last term in the equation, -16, represents the fixed costs associated with producing the DVD copies, such as overhead costs, marketing and distribution costs, etc. These costs are not directly related to the number of copies produced and are constant regardless of how many copies are produced.

In summary, the equation P = -0.02n^2 + 3.4n - 16 represents the profit for a small independent movie company as a function of the number of DVD copies produced. The profit is affected by the cost of production, revenue generated from sales, and fixed costs. As the number of copies increases, the cost of production increases, the revenue generated increases, and the fixed costs remain constant. The profit is the difference between the revenue generated and the costs incurred.

The length of the median of the trapezoid is 12.

The area of a trapezoid is given by the formula (1/2)h(b1+b2), where h is the height and b1 and b2 are the lengths of the bases. We know that the area is 60, the height is 5 and b1 = b2 + 4.

So, we can write the equation as follows:

(1/2) * 5 * (b1 + b2) = 60

To find the length of the median of a trapezoid, we need to find the length of the mid-segment. The mid-segment of a trapezoid connects the midpoints of the non-parallel sides. The length of the midsegment is the average of the lengths of the bases.

So, the length of the median is (b1 + b2) / 2.

We can substitute the value of the area to find the lengths of the bases and then use that to find the length of the median.

(1/2) * 5 * (b1 + b2) = 60

(1/2) * 5 * (b1 + b2) = 60

b1 + b2 = 24

b1 = b2 + 4

b2 = 24 - b1

b1 = (24 - b1) + 4

b1 = 24 - b1 + 4

b1 = 28 - b1

b1 = 28 - (24 - b1)

b1 = 4 + b1

b1 = b2 + 4

b1 = b1

So, the lengths of the bases are equal to 14 and 10.

Length of median = (14 + 10) / 2 = 12.

Therefore, The length of the median of the trapezoid is 12.

x - y = 8 (the difference between the two numbers is 8)

To find the product of the two numbers, we can multiply x and y:

xy = x(x - 8) = x^2 - 8x

To find the minimum value of the product, we can take the derivative of this expression with respect to x and set it equal to 0:

d(xy)/dx = 2x - 8 = 0

In geometry, a polygon is a two-dimensional closed object with straight sides that is flat or planar. It doesn't have any curved edges. A polygon's sides are also known as its edges. The vertices (or corners) of a polygon are the spots where two sides meet.

Here,

A square has 4 sides and 2 diagonals.

Now, a pentagon will have 5 sides and 5 diagonals

A hexagonal when drawn will have 6 sides and 9 diagonals

Thus, we see that;

When n = 4, d = 2

When n = 5, d = 5

When n = 6, d = 9

Using combination, we will find number of pairs of 2 vertices that can possibly be formed from n-vertices. Thereafter we will subtract n from that since it's neighboring vertices can't combine with the current one.

Thus, we have;

C(n, 2) - n

This gives s;
