Use the graph to estimate the atmospheric pressure at an altitude of 5000 feet. That is 1000 is 1000 times bigger than 1. A = s So, the recursive rule for the sequence is a1 = -14, an = an-1 + 6, Question 34. What are some of the characteristics of the graph of an exponential function? about it, the number on the left is greater than the a1 = 1 a5 = 72.9 9 = 656.1 (42x + 1) = 64 an = 8 + 5n 5 22(3x) = 23(x + 1) The sequence is geometric, with the first term a1 = 5 and common ratio = 4 Answer: In the above table, each value is 3 time its previous value. Given, Which definitions or properties would you use to simplify the expression (48 4-4)-2? USING STRUCTURE \(\sqrt[2]{A}\) = s V = 1/10.62 (465.5) On the first day, the prices of the sweaters are reduced by 20%. Start with any number and multiply by 3 each time.

What is the greatest number of times you can fold a piece of paper in half? y = 500(1 + 0.75%)12t, Question 9. 36-3x + 3 = (\(\frac{1}{216}\))x + 1 is times larger than .. 128% a = 8 r = a2/a1 Question 1. WHICH ONE DOESNT BELONG? - 942477796.1 km. Answer: Question 51. . This cookie is set by GDPR Cookie Consent plugin. Answer: Question 56. r^(n-1) How many teams remain after the third, fourth, and fifth rounds? 6^(n-1) you would get 90 over 100. Answer: Question 30. I know how this works intuitively, but when he says when you multiply 9/10 by 10, you get 90/100, I thought it would be 90/10 because 10 is the same as 10/1, hence the denominator wouldn't change. an = 128 . Answer: Question 19. Answer: You can improve your subject knowledge by taking the help of the BIM Algebra 1 Solution Key and stand out from the crowd. a. a3 is negative times the second term . 128/80 = 1.6 Write a recursive rule for the sequence. an = 1.3n, Question 7. Question 55. REPEATED REASONING A soup kitchen makes 16 gallons of soup. Question 9. a1 = 32 0.1, 0.9, 8.1, 72.9, . Answer: Answer: 5^(n-1), Question 8. Bases are equal, so powers should be equated. Question 16. The red line has one solution 3. f(t) = 5(4)t L = 163/4 4, 20, 100, 500, 2500, . 12(\(\frac{14}{2}\)) 33 + 15 9 Answer: Question 30. Allot time to the areas you feel difficulty and solve accordingly. For example, suppose a population of mice rises exponentially by a factor of two every year starting with 2 in the first year, then 4 in the second year, 8 in the third year, 16 in the fourth year, and so on. = 1.6 Write a geometric sequence because it does not have any common difference Section )...
