Hippocrates of Chios was the first to show that the area of a disk

Who discovered area formula?

In the 5th century BCE, Hippocrates of Chios was the first to show that the area of a disk (the region enclosed by a circle) is proportional to the square of its diameter, as part of his quadrature of the lune of Hippocrates, but did not identify the constant of proportionality.

A large part of the field of operations research is the use of statistical equations to solve problems in business or military operations.

Music, linguistics, and philosophy all use mathematical models (for example, intensively in analytic philosophy).

A model is, for example, the method for the area of a circle, πr2.

Radius of a circle is the distance from the center of the circle to any point on it's circumference. It is usually denoted by 'R' or 'r'. This quantity has importance in almost all circle-related formulas. The area and circumference of a circle are also measured in terms of radius.

Α= pi r^2

Divide each side by pi

A / pi = r^2

Take the square root of each side

sqrt( A / pi ) = sqrt(r^2)

sqrt( A / pi ) =r

The lengths 3, 14, and 10 form a obtuse triangle

It's simpler than it seems to determine whether a triangle has three side lengths. The Triangle Inequality Theorem, which asserts that the sum of a triangle's two side lengths is always greater than the third side, will suffice. You will have a triangle if this holds true for each of the three possibilities of increased side lengths.

Theorem of Triangle Inequality. This theorem merely states that the third side of a triangle cannot be smaller than the total of the first two sides. You will have a valid triangle if this holds true for each of the three possible combinations. To confirm that the triangle is feasible, you will need to go through each of these combinations one at a time. Theorem a+b > c, a+c > b, and b+c > a can alternatively be thought of as an inequality. The triangle has sides of lengths a, b, and c.

A constant of dilation is a number used to change the size of a figure while preserving its shape. It is also known as a scale factor.

The constant of dilation is used in a dilation transformation, a type of transformation that changes the size of a figure without changing its shape or orientation.

The constant of dilation is typically represented by the letter "k" and is a number greater than 0. If the constant of dilation is greater than 1, the dilation will increase the size of the figure. If the constant of dilation is less than 1, the dilation will reduce the size of the figure. And if the constant of dilation is equal to 1, the dilation will not change the size of the figure.

It's important to note that the constant of dilation is a factor that applies to all the points of the figure, and it's the same for all the points of a figure during a dilation transformation.

Answer:

-4/9

Step-by-step explanation:

Line f has the same slope as line e. Parallel lines have the same slope.

Line e has the slope -4/9.

Line f has the slope -4/9.

The calculations 4(2/9) is 8/9 1, 2(2/5) is 4/5 1, and 8(2/5) is 16/5 > 1, 6×(1/5) is 6/5 > 1, 5×(1/4) is 5/4 > 1.

If q is less than 0, a fraction is expressed as p/q. A proper fraction is one that follows the rules, and an improper fraction is another. The numerator in proper fractions is less than the denominator, whereas in improper fractions, the opposite is true.

We are aware that when multiplying fractions, we can eliminate terms from the numerator and denominator of other fractions to make the problem simpler, and we can also multiply numerators and denominators together.

∴ 4×(1/4) = 1.

4×(2/9) = 8/9 < 1.

2×(2/5) = 4/5 < 1.

8×(2/5) = 16/5 > 1.

6×(1/5) = 6/5 > 1.

5×(1/4) = 5/4 > 1.

The calculations 4(2/9) = 8/9 1, 2(2/5) = 4/5 1, and 8(2/5) = 16/5 > 1, 6×(1/5) = 6/5 > 1, 5×(1/4) = 5/4 > 1.

(150 + x) + 130 >= 150 is the inequality equation for the state legislature, which consists of senators and members.

Mathematics uses the term inequality to describe a link between two expressions or values that is not equal. Thus, imbalance is the cause of inequality. The relationship between two non-equal values in mathematics is established by an inequality. Egality and inequality are not synonymous. Whenever two values are not equal, use the not equal sign (). Various inequalities are used to compare values, whether they are small or large. You can eliminate a lot of simple inequalities by modifying both sides until only the variables are left. Inequality is brought on by a number of things, though: On both sides, subtract or multiply negative values. Alternate between left and right.

The value of car to the nearest cent, after 16 years will  be $882.

The preceding table displays the increase in value of a car that cost $16,100 over time, where x represents the number of years and y represents the car's cash value.

The formula for the exponential regression will be as follows:

y = A₀e∧(kx)

Where k is a constant and A₀ is the exponential regression coefficient.

So value of y would be $16,100 if x = 0. Next, we have

16,100  = A₀ e∧(k*0)

A₀ = 16,100

The equation will then be:

y = 16,100e∧(kx)

Hence value of y would be $13,431 if x = 1. Next, we have:

13,431 = 16,100e∧(k*1)

e∧(k) = 0.834

Considering all sides, we then have:

ln e∧(k) = ln 0.834

k = -0.181

The equation will then be:

y = 16,100e∧(-0.181*x)

For 16 years,

y = 16,100e∧(-0.181*16)

y = 16100*0.054

After that, a car's value will be:

y = 882

The additive inverse of 3/-7 is -3/7. This means that when 3/-7 is added to its additive inverse, the result is 0.

The additive inverse of any number is the number with the same absolute value but with the opposite sign. Therefore, the additive inverse of 3/-7 is -3/7. When two numbers are added together, the signs of the numbers can affect the result. For example, when two negative numbers are added, the result is a negative number. When two positive numbers are added, the result is a positive number. When one number is positive and one number is negative, the result depends on the relative size of the two numbers. For example, if the positive number is larger than the negative number, the result is a positive number. However, if the negative number is larger than the positive number, the result is a negative number. In the case of 3/-7, the negative number is larger than the positive number, so the result of adding 3/-7 to its additive inverse is 0.

Slope is a measure of steepness of a line. In Algebra 1, It is how much the y-value changes when the x-value increases by 1.

y-intercept is the y-value of the line when it intersects with the y-axis, or the y-value of the line when the x-value of the line is 0.

This form is the most common form for expressing linear equations for graphing and is used when the slope and y-intercept is known.

Form

y = mx + b

Lets break it down. y and x stay as a variable when graphing is it only substituted for a constant when solving for x-intercept, etc.

m is the slope.

b is the y-intercept.

Q1

y = mx + b

y = 5x

Because 5 is the m value, the slope is 5.

Q2

y = mx + b

y = 3

Think about it. What cancels out any real value? Multiplying it by 0. If there is no coefficient behind the x, it means the slope is 0.

y = 0x + 3 = y = 3

Because 0 is the m value, the slope is 0.

When y is equal to a constant after solving, it is a horizontal line with the y-intercept of the constant it is equal to (in this case 3).

Q3

y = mx + b

x = 5

The slope is undefined.

When x is equal to a constant after solving, it is a straight vertical line with the x-intercept of the constant it is equal to (in this case 5). The slope is always undefined.

Step-by-step explanation:

We can write a function in terms of 'a' for the balance of Dani's savings account if she doesn't notice the monthly fee as:

f(a) = 200 - 5a

where 'a' represents the number of months that have passed since Dani turned 18 and the bank began charging her the monthly fee.

So, f(0) = 200 represents the initial balance in Dani's savings account when she turned 18.

f(1) = 200 - 5(1) = 195 represents the balance in Dani's savings account after 1 month.

f(2) = 200 - 5(2) = 190 represents the balance in Dani's savings account after 2 months and so on.

Therefore, the function f(a) = 200 - 5a represents the balance of Dani's savings account after 'a' number of months if she doesn't notice the monthly fee.
