Textbook Question

Chapter 6.4, Problem 2E

Reminder Round all answers to two decimal places unless otherwise indicated.

Wendy’s According to a report in The Wall Street Journal, Wendy’s revenue fell 3.2 % to $ 489.5 million in the second quarter of 2015 . That represents a quarterly decay rate, as a decimal of e − 0.0325 . Let R ( t ) denote Wendy’s revenue, in millions of dollars, t quarters after the second quarter of 2015 . Suppose that revenue continues to fall at this same rate.

a. Write the equation of change for Wendy’s revenue.

b. Find a formula that gives Wendy’s revenue t quarters after the second quarter of 2015 .

Students have asked these similar questions

(1) Let M and N be non-empty subsets of a linear space X, show that whether = U or not, and show that there whether exsits a liear function from P₂(x) into R' which onto but not one-to-one or not. ام (2) Let R be a field of real numbers and P,(x)=(a+bx+cx? / a,b,ce R} be a vector space over R, show that whether there exsit two hyperspaces A and B such that AUB is a hyperspace or not. (3) Let A be an affine set in a linear space X over afield F and tEA, show that A-t is a subspace of Xand show that if M and N are balanced sets then M+N is balanced set. (4) Write the definition of bounded set in a normed space, and write with prove an equivalent statement to definition. (5) Let d be a metric on a linear space X over a field F, write conditions on d in order to get that there is a norm on X induced dy d and prove that. (6) Let M be a non-empty subset of a normed space X, show that xEcl(M) iff for any r>o there exsits yEM such that llx-yll

Find all solutions to the following equation. Do you get any extraneous solutions? Explain why or why not. 2 2 + x+1x-1 x21 Show all steps in your process. Be sure to state your claim, provide your evidence, and provide your reasoning before submitting.

Directions: For problems 1 through 3, read each question carefully and be sure to show all work. 1. What is the phase shift for y = 2sin(2x-)? 2. What is the amplitude of y = 7cos(2x+л)? 3. What is the period of y = sin(3x-π)? Directions: For problems 4 and 5, you were to compare and contrast the two functions in each problem situation. Be sure to include a discussion of similarities and differences for the periods, amplitudes, y-minimums, y-maximums, and any phase shift between the two graphs. Write in complete sentences. 4. y 3sin(2x) and y = 3cos(2x) 5. y 4sin(2x) and y = cos(3x- -플)
