Your progress has been saved Question 1 of 30 lan is considering changing his electricity plan. With his current plan, he pays $0.95 per kilowatt (kw) of energy usage, regardless of whether the usage is during peak hours or off-peak hours. lans average monthly billis about $125, due to the fact that he consumes an average of 131 kw per month. At least 50 kw are consumed during peak hours and at least 45 kw are used during off-peak hours each month. The new energy plan offers to change lans rates to $1.05 per kilowatt during peak hours and S0.79 per kilowatt during off-peak hours. lan decides to sign up. Without completely changing his energy usage habits, what is the best way for lan to consume energy while minimizing his monthly bill on the new plan? O lan cannot continue to consume a total of 131 kw without paying more than $125 on the new plan. Changing back to his old plan makes the most sense economically. The only way for lan to maintain his $125 average bill on this new plan is if he consumes only 50 kw during peak hours and 45 kw off peak. However, this strategy will lower his total kilowatt usage to 95 kw per month. OIf lan consumes 85 kw during peak hours and 45 kw during off-peak hours, he can continue to consume 131 kw of energy per month while lowering his bill to $124.80. if lan consumes 50 kw during peak hours and 81 kw during off peak hours, he can continue to consume 131 kw of energy per month while lowering his bill to $116.49 Previous

O The solution is the set of all ordered pairs whose x-coordinate is in the interval (4, oo) and whose y-coordinate is in (oo, 3] The solution is the set of all ordered pairs whose x-coordinate is in the interval (-0o, 4) and whose y-coordinate is in (-0o, 3]. O The solution is the set of all ordered pairs whose x-coordinate is in the interval (-00, 4) and whose y-coordinate is in (-o0, 3). The solution is the set of all ordered pairs whose x-coordinate is in the interval (4, oo) and whose y-coordinate is in (oo, 3).

Frederick is constructing a right triangle out of recycled metal. He will construct each side of the triangle from a different piece of metal. Frederick must decide which side of the triangle should be constructed from the longest piece of meal. To reach a decision, he uses a diagram like the one shown to compare the values of a and c. 15 0 2017 FipSwitch.

Bernice is a furniture maker who specializes in creating dining tables out of recycled material. Her total profit from these tables, p, is represented as a function of the number of dining tables sold, s. Each table costs $300.00. For every standard dining table she makes, she uses 8 recycled wall studs. She has 200 recycled wall studs on hand. Bernice wants to estimate her possible profit based on the materials she has on hand. What are the domain and range of P(s), Bernices profit? How do you know this? Select the option that correctly answers both questions. 0 Because Bernice has 200 wall studs on hand, she can fulfill 25 table orders at most. She can sell between 0 and 25 tables, and thus the domain is [0, 25]. Bernices profit is a function of the number of tables sold. Since she can sell as few as 0 tables, her minimum profit is SO. And, since she can sell as many as 25 tables at $300 each, her maximum profit is $7500. Thus, the range is [0,7500] Theoretically, Bernice can sell as many tables as are ordered, and thus the domain is (0, oo). If she can make infinitely many dining tables, she will make an infinite amount of money, and thus the range is [0, oo). Because Bernice has 200 wall studs on hand, she can fulfill 25 table orders at most. She can sell between 0 and 25 tables, and thus the range is [0, 25]. Bernices profit is a function of the number of tables sold. Since she can sell as few as 0 tables, her minimum profit is she can sell as many as 25 tables at $300 each, her maximum profit is $7500. Thus, the domair is [0, 7500]. O $0. And, since oBecause Bernice has 200 wall studs on hand, she can fulfill 25 table orders at most. She can sell between 0 and 25 tables, and thus the domain is (0, 25). Bernices profit is a function of the number of tables sold. Since she can sell as few as 0 tables, her minimum profit is SO. And, since she can sell as many as 25 tables at $300 each, her maximum profit is $7500. Thus the range is (0, 7500).
The value of a volatile stock is monitored for one week. The dollar value of the stock per share, V, is described by the function Vd), where d represents the number of the day of the week after Sunday. (Therefore, Sunday is when 0 s d < 1, Monday is when 1 s d < 2, Tuesday is when 2 s d < 3, etc) The function V(d) is shown in the graph. Number of Days After Sunday 2017 Rİpswitch. Created using GeoGebra. Use the graph to determine the following: Part A: What was the lowest dollar value per share that the stock reached that week? Part B: On what day did the stock reach its lowest value? Part C: Parts A and B identify the x and y-coordinates of the _Iblankl. What word correctly fills in the blank in the previous sentence? Select a total of three answers: one for Part A one for Part B, and one for Part C. A: $1.60 C: minimum
