Section 6.2 a = 1,156,530 Question 6. ones place, they seem comparable to each other. (Section 6.3 and Section 6.4) a2 = 0.02 Points are (0, 500) (1, 410) (2, 275) Do the terms form a geometric sequence? From the model, P =(0.99988)a the decay constant/ factor is 0.99988 y = 2(9)x Answer: r = 1 162x + 4 =163x 1 As the independent variable x changes by a constant amount, the dependent variable y is multiplied by a constant factor. about it, the number on the left is greater than the Simple, 99 has 2 digits and 1 is a single digit, so add them together and you get the correct answer of 3 digits. g. 2x/2 = \(\frac{1}{4}\) x = 1, Answer: Identify the percent rate of change. Is it possible for an exponential equation to have two different solutions? Question 41. iv. So, it represents an arithmetic sequence. \(\sqrt{64}\) Answer: 64, 32, 16, 8, 4 Answer: Question 51. Explain your reasoning. The value of the car decreases by 14% annually. A magnitude 8.7 earthquake is 794 f(4) = 5(256) Question 35. 729^\(1 / 6\) Give an example to justify your answer. a5 = 27 . 243, 81, 27, 9, 3, . Physical Chemistry is the hardest branch of chemistry. Explain your reasoning. Answer: Born and raised in the city of London, Alexander Johnson studied biology and chemistry in college and went on to earn a PhD in biochemistry. v(5) = 25000(1 0.14)5 t = 3 f(t) = 4(1.25)t + 3 128, 96, 72, 54, .
