● The pythagorian theorem

The pythagorian theorem is used to find a missing side of a right triangle.

It states that the square of the hypotenus of a right triangle is equal to the sum of the squares of the two other sides.

Let a be the hypotenus, b and c are the othet sides:

☆☆☆☆☆ a^2 = b^2 + c^2☆☆☆☆☆

There are more than 350 way to prove this theorem.

Step-by-step explanation: becuase 2/4 + 3/6 = 1

Answer: 6/6 = 1

Step-by-step explanation:

First, if you were to look at both fractions they both equal to 0.5 or one half.

Therefore, 2/4 = 1/2

And, 2/4 = 1/2

1/2 + 1/2 = 1

Answer:

-0.4n-13

Step-by-step explanation:

The estimate of 179% of 41 by rounding is about 73.19.

To find this estimate, first convert the percentage to a decimal by dividing it by 100: 179/100 = 1.79. Then, multiply this decimal by 41: 1.79 * 41 = 73.39.

The missing variables on item 2 are given as follows:

The three trigonometric ratios are the sine, the cosine and the tangent of an angle, and they are obtained according to the formulas presented as follows:

For the angle of 60º, we have that:

Hence the length o is given as follows:

tan(60º) = o/12.

\(\sqrt{3} = \frac{o}{12}\)

\(o = 12\sqrt{3}\)

Applying the Pythagorean Theorem, the length i is given as follows:

i² = 12² + \((12\sqrt{3})^2\)

i² = 576

i² = 24²

i = 24.

A similar problem, also about trigonometric ratios, is given at brainly.com/question/24349828

#SPJ1

Answer:

o = 12√3

i = 24

Step-by-step explanation:

From observation of the given right triangle, we can see that two of its interior angles measure 60° and 90°. As the interior angles of a triangle sum to 180°, this means that the remaining interior angle must be 30°, since 30° + 60° + 90° = 180°. Therefore, the triangle is a special 30-60-90 triangle.

The side lengths in a 30-60-90 triangle have a special relationship, which can be represented by the ratio formula a : a√3 : 2a, where "a" represents a scaling factor that can be any positive real number.

In triangle #2, the shortest leg is 12 units.

As "a" is the shortest leg, the scale factor "a" is 12.

The side labelled "o" is the longest leg opposite the 60° angle. Therefore:

\(o = a\sqrt{3}=12\sqrt{3}\)

The side labelled "i" is the hypotenuse of the triangle. Therefore:

\(i= 2a = 2 \cdot 12=24\)

Therefore:

Answer:

There's many vertical angles but here are two simple ones: 140° and 40°.

The total volume of the air space of spherical ball is A = 12.265625 inches³

Given data ,

Since each tennis ball has a diameter of 2.5 inches, the radius of each ball is 1.25 inches.

The air space around the balls can be thought of as a cylinder with a height equal to the diameter of one ball and a radius equal to the radius of one ball.

The height of the cylinder is 2.5 inches, and the radius is 1.25 inches.

The formula for the volume of a cylinder is:

V = πr²h

V = ( 3.14 ) ( 1.25 )² ( 7.5 )

V = 36.796875 inches³

where V is the volume, r is the radius, and h is the height.

So, the volume of the one ball is:

V₁ = ( 4/3 )π(1.25)³

V₁ = 8.177083 inches³

The total volume of three balls is = volume of 3 spherical balls

V₂ = 3V₁ = 3(8.177083) ≈ 24.53125 cubic inches

Therefore, the total volume of the air space around the three tennis balls is approximately A = 36.796875 inches³ - 24.53125 inches³

A = 12.265625 inches³

Hence , the volume of air space is A = 12.265625 inches³

Using TI 84 calculator,

P(X > 39500) = normal cdf ( 39500 , 1000, 37764 , 5100)

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics. Probability and odds are different concepts. Odds are the probability that something happens divided by the probability that it doesn't happen

8000 = 5000 ( 1 + 6%/4) ^ 4t

8000 = 5000 ( 1 + 0.06/4) ^4t

8000 = 5000 ( 1.015 ) ^ 4t

The average rate of change of the function f(x) = x² + 4x - 2 over the interval [-8,3] is -1.

Given the function in the question;

f(x) = x² + 4x - 2

Interval -8 ≤ x ≤ 3

To find the average rate of change of the function f(x) = x² + 4x - 2 over the interval [-8,3],

we can use the following formula:

average rate of change =  \(\frac{f(b) - f(a)}{b - a}\)

Where a and b are the endpoints of the interval.

Substituting the values of a = -8 and b = 3 into the formula, we get:

average rate of change =  \(\frac{f(3) - f(-8)}{3 - (-8)}\)

We can now find the values of f(3) and f(-8) using the formula for f(x):

f(x) = x² + 4x - 2

f(3) = (3)² + 4(3) - 2

f(3) = 9 + 12 - 2

f(19) = 19

f(x) = x² + 4x - 2

f(-8) = (-8)² + 4(-8) - 2

f(-8) = 64 -32 - 2

f(-8) = 64 -34

f(-8) = 30

Hence:

average rate of change =  \(\frac{f(3) - f(-8)}{3 - (-8)}\)

\(=\frac{19 - 30}{3 - (-8)}\\\\=\frac{-11}{11}\\\\= -1\)

Therefore, the average rate of change is -1.

The statement refers to the way that symbols are represented in sequences, a common practice in formal language theory, by employing a notation that makes symbols a part of the sequence.

In formal language theory, a language is often defined as a set of strings over an alphabet. By representing any alphabetic sequence of symbols as a single string using the notation outlined in the statement, we are able to recognise the language that comprises that sequence as a collection of strings. A subset of the language having all possible strings over the alphabet (a, b, and c) is the set of strings abc, which may be used to represent the language including the sequence (a, b, and c). So, this notation offers an easy approach to discuss languages and the sequences that make up such languages.

The conversion table refers to the tabulated standard units of measurement, showing temperature, length, area, volume, weight, and metric conversions

For instance, the conversion table shows that 12 inches equal 1 foot.

The length of the fossil = 489.44 inches

12 inches = 1 foot

489.44 inches = 40.8 feet (489.44 ÷ 12)
