The distance between pylon B and pylon C is 1017.60 m, using the Pythagorean theorem.

The Pythagorean Theorem, also known as Pythagoras' Theorem, states that the area of the large square is equal to the sum of the areas of the two smaller squares.

In terms of algebra, the triangle's a and b are its legs, and its hypotenuse is equal to its product, a2 + b2 = c2.

Since it provides the foundation for the definition of distance between two points in Euclidean geometry, the theorem is crucial. Anyone who took geometry in high school, in my opinion, cannot possibly fail to remember it long after other math concepts have been completely forgotten because it is so fundamental and well-known.

Using Pythagorean theorem

The hypotenuse is the Distance from pylon B to pylon C

c = [tex]\sqrt{a^2 + b^2}[/tex]

Distance from pylon B to pylon C =  [tex]\sqrt{845^2 + 567^2}[/tex]

                                                        = 1017.60 m

Thus, The distance between pylon B and pylon C is 1017.60 m, using the Pythagorean theorem.

Step-by-step explanation:

Jasmine will make $61000 annually in 2019.

A percent increase refers to how much a percentage has gone up over time.

Given that, Jasmine started a new job in 2010 with an annual salary of $38,000, her salary increases by 5.4% each year,

We know that, percentage of increase =

A = P(1+r)ⁿ

A = Final amount

P = Initial amount

r = rate

n = time

Here, A = ?

P = 38000

Time = 2019 - 2010 = 9

r = 5.4% = 0.054

A = 38000(1+0.054)⁹

A = 38000(1.054)⁹

A = 61002.7053

A ≈ 61000

Hence, Jasmine will make $61000 annually in 2019.

The scale used for measuring the intensity of the earthquake is Richter Scale.

American seismologists Charles F. Richter and Beno Gutenberg developed the Richter scale (ML), a numerical indicator of an earthquake's size, in 1935. The height of the greatest seismic wave, as measured by the logarithm of its amplitude (height), is used to calculate the earthquake's magnitude.

Although the original Richter scale has been supplanted by other, more precise scales in modern science, the Richter scale is still frequently used incorrectly in news reporting of earthquake severity as a catch-all name for the logarithmic scale that earthquakes are measured on.

No, Since earthquake waves lose energy as they move through the earth, shaking is less powerful away from the fault. Compared to high-frequency waves, low-frequency waves lose strength across distance more slowly.

The magnitude scale, which measures an earthquake's size, is unaffected by distance from the event. The extent of damage depends on how violently the ground shakes when an earthquake occurs.

The depth of the earthquake, the distance from the fault, the underlying soil, and the characteristics of the buildings, particularly their height, intensity, are the subsequent primary elements impacting earthquake shaking strength. The brightness of a celestial object, like a star or galaxy, as judged by an observer at a particular distance from the object is known as its apparent magnitude. The apparent brightness increases with decreasing distance between observer and object.

The inverse of f(x) = log₁₀(x) is 10ˣ.

A logarithm is an exponent to which a base must be raised to generate a given number. Expressed mathematically, x is the logarithm of n to the base a if ax = n, in which case one writes x = logₐn.

A logarithm is defined using an exponent.

aˣ = b ⇔ logₐb = x

Here, "log" stands for logarithm. The arrow's right part is read as "Logarithm of b to the base a is equal to x".

We have the function,

Yes, the number, 4225, is a perfect square because it can be expressed as square of 65 which is a whole number, i.e., 4225 = 65².

In mathematics, a square number or perfect square is an integer that is the product of some integer with itself. For example, 25 is a square number, it is equals to 5² and can be written as 5×5. A perfect square always represented as second power of a number. Perfect Square Formula : Let us consider if N is a perfect square of a whole number x, then it can be written as N = product of x and x = x². So, the perfect square formula is, N = x². We have a number 4225. Now, we resolve 4225 into prime factors, we get, 4225 = 5×5×13×13 = 5×13×5×13

What is length of arc?

The distance between two places in a curve's section is known as the arc length. Any portion of a circle's circumference is an arc. An arc's angle at any given location is the angle created by the two line segments connecting that point to the arc's endpoints.

A circle has circumference 2πr.

240° is 240/360 of a circle or

24/36 = 6/9

= 2/3 of the circle

The arc is 2/3 of 2πr

= 2/3 x 2pi x 16 inches

General formula for the length of an arc is -

Arc Length = θ × r, with θ in radians 240 degrees
