REASONING 205/128 1.6 y = a(1 + r)t We know that the alligator always points towards the largest value. 17716. How can you define a sequence recursively? 8 4 + 20 . Simplify the expression . 6, 3, 0, -3, . Answer: an = a1 . g(0) = 8(0) + 16 = 10 Volume = 125 cm3 This ratio is called the common ratio. Student B claims she can form a linear system from the equations shown that has one solution. Graph the first four terms of the sequence. In the exponential growth function y = a(1 + r)t, the quantity r is called the ________. Find the value of h, k, or a. a6 = a5 + 5 Answer: Question 46. The common ratio is 1/2 (6a) = 36a Round your answer to the nearest thousandth. 4. V = s Question 46. x = 12/3 Answer: Question 58. a. a2 = -18 How many times larger is 500 than 50? The table shows the value of a camper t years after it is purchased. a1 = 7 Find the 2nd, 5th, and 10th terms of the sequence. Explain how writing a function in Exercise 39 part (a) on page 337 created a shortcut for answering part (b). Find both answers. g. 2x/2 = \(\frac{1}{4}\) Answer: Question 12. Not sure which number is the larger one. The sequence does not have a common difference. c. Did the student make a good choice or should she have chosen to live on campus? So plus 8/1000. x 1 = -3 Answer: Question 54. a3 b3 = -27 0.75 m = (0.00016)C2.73 Write a recursive rule for the explicit rule. The time t (in seconds) it takes molecules to diffuse a distance of x centimeters is given by t = \(\frac{x^{2}}{2 D}\), where D is the diffusion coefficient. 1 r =\(\frac{3}{5}\) -3, -4, -7, -11, -18, . 162x + 4 =163x 1 a2 = -4 Question 7. Answer: Question 66. 3x = -6 Answer: 375, -75, 15, -3, . n = 3 + 1 (2)(2) = 2 2 2 2 2 = 32 Texas and Mexico share 1,254 miles of common border and are joined by 28 international bridges and border crossings. f(1) = 3, f (n) = f(n 1) + 7 MODELING WITH MATHEMATICS The X-ray shows the lengths (in centimeters) of bones in a human hand. Answer: a7 = 13 . Write a different infinite geometric sequence that has the same sum. The blue line has two or more solution. . a5 = 6144 4 = 24,576 272/3= \(\sqrt[3]{27}\) = 3 = 9 y 800(0.71)t b. y = 2(3)x Answer: -25, -18, -11, -4, . = 16, Answer: = 84 27 + 15 81 a6 = 9 \(\frac{3}{2}\) = \(\frac{27}{2}\) When bases are equal powers should be added. Each term of the sequence is 10 more than the preceding term. Which equation does not belong with the other three? = (-4) a2 = 10 + 5 = 15 Direct link to Jrepsa's post At 1:00 why does Sal use, Posted 4 years ago.
