Which equation represents the magnitude of an
earthquake that is 100 times more intense than a
standard earthquake?
M=log-
100S
M=log
100S
OM=log(1005)
| © M=109100
DONE

1. M = log  S /S = 0

2. M = log  100S /S  

3. The magnitude is M = 2

Step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

x/3-10=8

x/3=18

x=48
