2. The following formula models the Richter scale which describes the magnitude, M, of an earthquake with amplitude A where k is a predetermined constant.
M = log
a. What is the base of the log in this formula?
(1 point)
b. Change this formula to exponential form.
(2 points)
c. Use the above information to explain why a 7.0 earthquake has ten times the amplitude of a 6.0
earthquake.
(2 points)
d. What would M be if A = k? What would that mean in real life?
(2 points)

dude   i don't even know. i've been trying for hours.

step-by-step explanation:

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
