Answer:
The first earthquake is 1.9 times greater than the second
Step-by-step explanation:
We need to substract
M1 and M2
M1 - M2 = ㏒(x1/c) - ㏒(x2/c)
by properties of the logarithm
= log(x1) - log(c) - (log(x2) - log(c))
= log(x1) - log(x2)
But, we know that x1 = 80*x2
So,
= log(80) + log(x2) - log(x2)
= 1.903
Answer:
The error that Kendra made in her equation was subtracting 5.5 from the variable d instead of adding it which is wrong.
The perimeter is 30 im pretty sure
The expression 30 + 12 can be rewritten as 2x(13+8)
