Answer: "possible" rational roots: ±1/5, ±3, ±1
Step-by-step explanation: Take plus or minus the factors of the constant divided by the factors of the leading coefficient.
In this case, the constant is 3, so the factors are 1 and 3, and the leading coefficient is 5, so the factors are 5 and 1.
1/5, 3/5, 1/1 and 3/1 are possibilities, simplify and attach the ± to each.
Answer: $ 48
Explanation:
1) kw-h is a measure electric energy consumption.
2) The cost of electric energy is considered proportional to the number of kw-h (kilo watts - hour) consumed. Thi is:
cost------- = constant = unit cost = 0.40 $/kw-h
kw-h
3) Then, the total cost is the total number of kw-h times the unit cost. This is:
8 h × 15,000 watts × 1 kw / 1,000 watts × 0.40 $ / kw-h = $48.
That is the cost to charge the robot each night
