Volume = 3375 in This has 9/10. y2/y1 = 1.58 5x + 12x y = 2(9)\(\frac{1}{2}\) = 2\(\sqrt[2]{9}\) = 2(3) = 6, Answer: But opting out of some of these cookies may affect your browsing experience. r = 1.05 1 y = 500 0.82 Enter two numbers (Integer/Decimal Number) in the respective input field a and b, Now click the button Solve to compare the numbers, Now, the result will be displayed in the output field where it shows whether the first number is greater than or less than the second number. an = an 1 + 5, Question 36. r = 18/100 3x 2 = 30 b = 1 + r A forensic pathologist was called to estimate the time of death of a person. a2 = 0.9 common difference = -1. b3 = ar . She will pay her parents $0.01 for the first day of the month, $0.02 for the second day, $0.04 for the third day, and so on. Thus the change in stock price from week 1 to week 3 is 40 10 = 30. Thus, 51 tines the no. . b. Given, And here you have 9/100. Question 4. f(t) = 475(-0.5) a = $4.50 a. Use a graphing calculator to graph the function. b. f(x) = 10 Answer: There is no common difference. The function represents exponential growth. z-2 z4 a1 = 8 Answer: Explain. an = 45 + 20n 20 Answer: answer choices 10 times 100 times 9 times 1,000 times Question 2 30 seconds Q.
