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 15 (1 point) A bacterial count starts with 212 bacteria. After 24 hours the count is 250. What is the doubling period for this bacteria? The doubling period, to the nearest tenth of an hour, is: Your Answer: Answer Logarithmic Functions Question 16 (1 point) The value of log; 81 - 2log, 49 + log2 - + log; b + log lis: A/ Question 17 (1 point)Question 16 (1 point) The value of log, 81 + 2log- 49 + log2 2 +log; b + log, lis: A Question 17 (1 point) if log, 8 = 3 and log, b = . then the value of log, b + log, a, to the nearest hundredth is: Question 18 (1 point) k = - log, 5 can be written as: Ohk = 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. Noah made his first error in line: MacBook ProQuestion 21 (1 point) Given the table below and log, (a + b) = y + 1, then determine the numbers from the table that represent the x-intercept and the y-intercept of the inverse log. (b) W log. (a) la - b N 4 a2 log (b) - log(a) The number that represents the x-intercept of the inverse is: and the number that represents the y-intercept of the inverse is: Question 22 (1 point) The graph of y = 10g X can be transformed to the graph ofy = logg by either a stretch or a translation. The two transformation equations areQuestion 22 (1 point) The graph of y - 10gg 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?) ?
