The term "numerical evidence" describes information that is expressed in a numerical manner, such as numbers, quantities, or statistical data. It is thought to be objective and quantifiable, and it is used to support a claim or argument.

The quantity of sales made during a specific business quarter is an example of numerical data. Simply put, if the response includes a number, the data is quantitative (numerical).

Let the equation be [tex]$\lim _{x \rightarrow 6}\left(\frac{x^2-x-30}{x^2-3 x-18}\right)$$[/tex]

Simplifying the above equation, we get

The value of the trigonometric equation sin D = 0.923

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be represented as ΔBCD

Now , the measure of BC = 24

The measure of side CD = 10

So , the measure of hypotenuse BD = √ ( BC )² + ( CD )²

Substituting the values in the equation , we get

The measure of BD = √ ( 576 ) + 100

The measure of BD = √ ( 676 )

The measure of BD = 26

Now , from the trigonometric relations ,

sin θ = opposite / hypotenuse

Substituting the values in the equation , we get

sin D = 24 / 26

Answer:

50

Step-by-step explanation:

4x10=40.

5x10=50

Answer:

Step-by-step explanation:

To increase a quantity in a given ratio, we can follow these steps:

Step 1: Find the total increase in the quantity.

Suppose the original number of books is "b". The total increase in the number of books is 40, so:

b + 40 = b

Step 2: Divide the total increase into two parts in the given ratio.

In this case, the ratio is 5:4, so we can divide the increase of 40 into two parts in the ratio 5:4. Let's call the first part "x". Then, the second part is 40 - x.

The first part (5x) is 5 times the second part (4x), so:

5x = 4(40 - x)

Step 3: Solve for x.

Expanding the right side:

5x = 160 - 4x

Adding 4x to both sides:

9x = 160

Dividing both sides by 9:

x = 40/9

Step 4: Find the new number of books.

The first part of the increase (x) is 40/9, and the second part (40 - x) is 40 - 40/9 = 40 * 9/9 - 40/9 = 40 * 8/9. The new number of books is the original number plus the two parts of the increase:

b + 40/9 + 40 * 8/9 = b + 40

So, the new number of books is b + 40.

======================================================

Explanation:

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

Let's see how many seconds there are in a day.

[tex]1 \text{ day} = (1 \text{ day})*\frac{24 \text{ hrs}}{1 \text{ day}}*\frac{60 \text{ min}}{1 \text{ hr}}*\frac{60 \text{ sec}}{1 \text{ min}}\\\\=\frac{24*60*60}{1*1*1}\text{ sec}\\\\=86,400\text{ sec}\\[/tex]

I set up those fractions so that the units "day", "hours", "minutes" cancel out. The only unit left over is "seconds".

There are exactly 86,400 seconds in 1 day.

This leads to the fact the sink fills up at a rate of 86,400 drops per day, since the leak rate is 1 drop per second.

----------

1 drop = 0.003 cubic inches approximately

x of those drops give a volume of 0.003x cubic inches, where x is some positive whole number. Set this equal to the volume of the sink and solve for x.

0.003x = 3584

x = 3584/0.003

x = 1,194,666.66666667 approximately

Round up to the nearest whole number to get 1,194,667

The sink starts to overflow when we have 1,194,667 drops of water in it.

Divide this over 86,400 mentioned earlier.

(1,194,667)/(86,400) = 13.8271643518519 approximately.

Round that however you need to. If for instance you round to 3 decimal places, then it would be 13.827

Trigonometric ratio in option (c) tan C will not have the same value as sin A.

Trigonometric functions are defined as the periodic functions which relate an angle in a right angled triangle to the ratios of the length of two sides.

Given a right angled triangle ABC given below.

ABC angle is 90° and angle ACB is 45°.

Then angle BAC = 180° - (90° + 45°) = 45°

Since two angles are equal, it is an isosceles triangles.

So opposite sides to the equal angles are equal.

AB = BC

AC is the hypotenuse.

Sin A = Opposite side / Hypotenuse = BC / AC

(a) Cos A = Adjacent side / Hypotenuse = AB / AC = BC / AC

(b) Sin C = AB / AC = BC / AC

(c) Tan C = Opposite side / Adjacent side = AB / BC = BC / BC = 1, not equal to Sin A

The linear equation that passes through the two given points is:

y = (-1/3)*x - 2/3

A general linear equation can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If a line passes through the points (x₁, y₁) and (x₂, y₂) then the slope can be written as:

a = (y₂ - y₁)/(x₂ - x₁)

Here we know that the line passes through (4, -2) and (-2, 0), then the slope is:

a = (0 + 2)/(-2 - 4)= 2/-6 = -1/3

y = (-1/3)*x + b

To find the value of b, we can replace the values of any of the points in the equation, if we use (-2, 0) we will get:

0 = (-1/3)*-2 + b

0 = 2/3 + b

-2/3 = b

The average thickness of the metal sheet is 0.0423 inches.

In statistics, the mean is a measure of central tendency of a set of data. It is also referred to as the arithmetic mean and is calculated by adding up all the values in the data set and dividing by the total number of values.

Mean = (sum of all values) / (number of values)

For example, suppose we have the following set of data: 5, 7, 9, 11, 13. To find the mean, we add up all the values and divide by the total number of values, which is 5 in this case:

Mean = (5 + 7 + 9 + 11 + 13) / 5

Mean = 9

Therefore, the mean of this data set is 9.

The mean is a commonly used measure of central tendency because it takes into account all the values in the data set and is sensitive to changes in the data. However, it can be affected by outliers or extreme values in the data set, which can skew the results.

To find the average thickness of the sheet, we need to add the five measurements together and then divide by 5 (the number of measurements):

Average thickness = (0.0401 + 0.0417 + 0.0462 + 0.0407 + 0.0428) / 5

The table offers an average rate of change greater than the average rate of change of the function f(x) = x² + 2 · x - 1.

In this problem we need to determine two average rates of change, one from an equation and another from a table. Graphically speaking, average rate of change is the slope of a line secant to a curve and it can be computed by secant line formula:

m = [f(2) - f(- 2)] / [2 - (- 2)]

First, we proceed to determine the average rate of change for the function f(x) = x² + 2 · x - 1:

f(- 2) = (- 2)² + 2 · (- 2) - 1

f(- 2) = 4 - 4 - 1

f(- 2) = - 1

f(2) = 2² + 2 · 2 + 1

f(2) = 9

m = [9 - (- 1)] / [2 - (- 2)]

m = 10 / 4

m = 5 / 2

m = 2.5
