Mathematically, the rating of an earthquake typically refers to its magnitude on the Richter scale.
The Richter scale is a logarithmic scale that measures the amplitude of seismic waves produced by an earthquake. Each increase of one unit on the Richter scale represents a tenfold increase in the amplitude of the seismic waves and approximately 31.6 times more energy released.
A rating of 7.6 on the Richter scale indicates a significant and powerful earthquake. It is considered a "great" earthquake and can cause widespread damage over an extensive area. The extent of the damage can depend on various factors, including the depth of the earthquake, the distance from populated areas, and the local building infrastructure.
It's important to note that while the magnitude of an earthquake provides a measure of its energy release, it doesn't directly indicate the extent of the damage or the specific geographical area affected. The effects of an earthquake can vary depending on factors such as local geology, distance from the epicenter, and the population density of the area.
Mathematically, the Richter scale provides a standardized way to quantify and compare the magnitude of earthquakes, aiding in the understanding and analysis of seismic events.

C. 2k^2 – k – 3
D. 2k^2 – k + 2
Answers
(2k+3)(k-1)
Use the distribute property
(2k)(k)+(2k)(-1)+(3)(k)+(3)(-1)
= 12k²-2k+3k-3
= 2k²+k-3
The answer is A

These are the choices:
x = 10; it takes 10 seconds to reach the maximum height and 10 seconds to fall back to the ground
x = 10; it takes 10 seconds to reach the maximum height and 20 seconds to fall back to the ground
x = 5; it takes 5 seconds to reach the maximum height and 10 seconds to fall back to the ground
x = 5; it takes 5 seconds to reach the maximum height and 5 seconds to fall back to the ground

The proof used the distributive property and the associative property of multiplication.
Option B is the correct answer.
What is an expression?
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the liketerms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To be specific, the distributiveproperty was used to break down the expression 4t + t as:
4t + t = (4 + 1)t ________(1)
And then the associativeproperty was used to rearrange the terms as:
(4 + 1)t = 5t ________(2)
From (1) and (2)
We have shown that 4t + t is equivalent to 5t.
Thus,
The proof used the distributive property and the associative property of multiplication.
