                                            WGU Applied Algebra FXO2 PFXP C957 Sample Questions (Q59-Q64):

                                            NEW QUESTION # 59
                                            The logistic function f(x), whose graph is shown, models the number of registrants for an academic conference, where x represents the number of weeks since registration opened and f(x) represents the number of registrants.

                                            How does the number of registrants change as time progresses from week 1 to week 7?

                                            Answer: D

                                            Explanation:
                                            The graph shows a logistic growth function for conference registration. From week 1 to week 7, the number of registrants is increasing because the graph rises as time moves forward. The curve also becomes steeper throughout this interval, meaning the number of registrants is increasing at a faster rate each week. In Applied Algebra, when a graph rises and its slope increases, the correct interpretation is "increases faster and faster." The graph is not decreasing, so both decreasing options are incorrect. The graph is also not flattening during this interval, so "increases slower and slower" does not match. Therefore, the correct answer is C.


                                            NEW QUESTION # 60
                                            The population of fish in a lake is changing according to the function
                                            P(t)=24t+185
                                            where tis the number of months since the beginning of the year and P(t)is the fish population at time t.
                                            Which interpretation of the rate of change is correct?

                                            Answer: D

                                            Explanation:
                                            The function is:
                                            P(t)=24t+185
                                            This is a linear function in the form:
                                            P(t)=mt+b
                                            where:
                                            m= " rate of change "
                                            and
                                            b= " initial value "
                                            In the function:
                                            P(t)=24t+185
                                            the coefficient of tis:
                                            24
                                            So the rate of change is:
                                            24 " fish per month "
                                            Because 24is positive, the fish population is increasing.
                                            The number 185is not the rate of change. It represents the starting fish population at the beginning of the year, when t=0:
                                            P(0)=24(0)+185=185
                                            Therefore, the correct interpretation is:
                                            " The number of fish in the lake is increasing at a constant rate of 24 fish per month. " So the correct answer is:
                                            # ( " B " )


                                            NEW QUESTION # 61
                                            The graph shows the value, O, in dollars, of an investment account over time.

                                            What represents the value of the account after 8 years?

                                            Answer: A

                                            Explanation:
                                            The graph shows the total value of an investment account as time increases.
                                            The horizontal axis represents:
                                            " Time in years "
                                            The vertical axis represents:
                                            " Total value in dollars "
                                            We need to find the value of the account after:
                                            8 " years "
                                            From the graph, when t=8, the curve is slightly above $2,200. The closest answer choice is:
                                            $2,221.12
                                            So the value of the account after 8 years is approximately:
                                            $2,221.12
                                            Therefore, the correct answer is:
                                            # ( " D " )


                                            NEW QUESTION # 62
                                            The spread of two viruses within a single population is modeled using the functions in the graph.

                                            What is a correct conclusion based on the graph?

                                            Answer: B

                                            Explanation:
                                            The graph compares the spread of two viruses over time.
                                            The horizontal axis represents:
                                            " time in months "
                                            The vertical axis represents:
                                            " percent of the population affected "
                                            The graph shows:
                                            Virus A as the solid blue curve.
                                            Virus B as the dashed blue curve.
                                            To determine which statement is correct, compare when each virus reaches the same population percentage.
                                            At 20%, Virus A reaches that level earlier than Virus B. The solid curve is already at 20%before the dashed curve reaches 20%.
                                            However, for higher percentages like 70%and 80%, Virus B reaches those levels before Virus A because the dashed curve becomes steeper and rises above the solid curve after about 50%.
                                            So the correct conclusion is:
                                            " Virus A affects " 20% " of the population before virus B does. "
                                            Therefore, the correct answer is:
                                            # ( " A " )
