( a) (0, -2) ( b) none O c) ( - 2, 0 ) O d) (1, 0)Question 5 [1 point] The expression is which equivalent to leg ?5 is O a) log 150 10g 2 Ob) 10g 3 + log 25 0:) 10g 100 leg 25 0 d} (log 5)(10g 15) O c + O d) + H\fQuestion 3 {1 point) I The magnitude of an earthquake can be calculated using the formula M =log(1) o where M is the magnitude of the earthquake on the Richter scale. irepresents the intensityI of an earthquake, and i0 represents the intensity' of an earthquake with a magnitude of 0. To the nearest tenth, an earthquake with a magnitude of 718 is C] 3; times as intense as an earthquake with a magnitude of 5.7.
