Hi, thank you for posting your question here at Brainly.
Simply substitute the value of the intensity to the variable i. Taking its logarithm to the base 10, the answer would be 7.8. Hence, 6 million ergs is equivalent to 7.8 based on the Richter scale.
f(x) = 2x + 1
To find the inverse, f^-1(x), of the function:
Put the function as an equation:
y = 2x + 1
Then move x to the left and y to the right;
x = 2y + 1
Then solve for y;
y = x/2 - 1/2
f^-1(x) = y
f^-1(x) = x/2 - 1/2
Answer:
y=X+2
Step-by-step explanation:
you can use the equation y=Mx+c to give this solution!
