The value of x when the richter scale rating scale is 8.4 is 251188643.151
<h3>What is a richter scale?</h3>
A richter scale is a numerical scale that is used for expressing the magnitude of an earthquake in a geographical area
<h3>How the richter scale works?</h3>
The richter scale takes the amplitude of the earthquake's largest seismic as an input and calculate (and display) the magnitude of an earthquake in the geographical area using a logarithmic function
<h3>How to determine the value of x?</h3>
The formula of a richter scale is expressed as:
log(x) = n
Where n represents the scale rating of the scale
In this case, n = 8.4.
So, we have:
log(x) = 8.4
Express as an exponent
x = 10^8.4
Evaluate the exponent
x = 251188643.151
Hence, the value of x when the richter scale rating scale is 8.4 is 251188643.151

2000=1800(1.04)^t,,log(1.11)/log(1.04)=t use the calculator,,,hope it helps :-)
To find the sum:
![{7a}^{3} + 14a + 12 + ( {- 6a }^{3} ) + {12a }^{2} - 7 \\ = {7a }^{3} - {6a}^{3} + {12a }^{2} + 14a + 12 - 7 \\ = {a}^{3} + {12a }^{2} + 14a + 5](https://tex.z-dn.net/?f=%7B7a%7D%5E%7B3%7D%20%2B%2014a%20%2B%2012%20%20%2B%20%28%20%7B-%206a%20%7D%5E%7B3%7D%20%29%20%2B%20%7B12a%20%7D%5E%7B2%7D%20%20%20-%207%20%5C%5C%20%20%3D%20%7B7a%20%7D%5E%7B3%7D%20%20%20-%20%20%7B6a%7D%5E%7B3%7D%20%20%2B%20%7B12a%20%7D%5E%7B2%7D%20%20%2B%2014a%20%2B%2012%20-%207%20%5C%5C%20%20%3D%20%20%7Ba%7D%5E%7B3%7D%20%20%2B%20%7B12a%20%7D%5E%7B2%7D%20%20%2B%2014a%20%2B%205%20)
Therefore the answer is a^3+12a^2+14a+5.
Hope it helps!
Answer:
28 Kg : 8 Kg
Step-by-step explanation:
Sum the parts of the ratio, 7 + 2 = 9 parts
Divide 36 Kg by 9 to find the value of one part of the ratio.
36 Kg ÷ 9 = 4 Kg ← value of 1 part of the ratio, thus
7 parts = 7 × 4 Kg = 28 Kg
2 parts = 2 × 4Kg = 8 Kg
36 Kg in the ratio 7 : 2 = 28 Kg : 8 Kg
Answer:
The length of each edge of the cube is 1 unit.
Step-by-step explanation:
Volume of the cube = x * x * x = x^3
So x^3 = 1
x = 1.
