Question 24 (1 point) Earthquake intensity, _ is given by the equation/ = To ( 10)" where m is the magnitude measured to the nearest tenth on the Richter scale and 10 is the reference intensity. In 1906, the San Francisco Bay area had an earthquake with a magnitude of 7.8 on the Richter scale. What would the magnitude of an earthquake 158 times less intense than the 1906 San Francisco Bay area earthquake be? The magnitude would be: 5.6 2.2 6.3 3.5 MacBook ProQuestion 19 (1 point) Ifloga b = 1. 52 , where a, b > 0, a * 1, then the value of loga (62) to the nearest hundredth is: Question 20 (1 point) Which expression is always equivalent tolog, (16a?) ?

MacBook ProNoah solved the following equation algebraically log-(x + 1) + log7(x - 5) = 1 and considered the characteristics of the graph. His class partner, Tyler, thought he made an error. In which step did Tyler find Noah's first error? Step 1 log- (a2 - 4x - 5) - 1 Step 2 - 4x - 5 Step 3 0 - 4x - 12 Step 4 0 6) (2 + 2) Step 5 6, or x = -2 Step 6 Domain: C Step 7 6 Step 8 Noah did not make an error.
