Answer:
The cost is $43.2
Step-by-step explanation:
The first thing to do here is to calculate the amount of energy consumed.
From the question, we are told that this is;
Power * Time
From the question, power = 1600 watts
Time = 9 hours
So amount of energy consumed = 1600 watts * 9 hours = 14,400 watts hour
It should be known that energy is measured in Kilowatts hour ; So therefore 14,440 watts hour is 14,440/1000 kwh = 14.4 kwh
Now, the cost per unit of energy is $3.00 per kwh
So the cost of using 14,400 watts hour would be 14.4 * 3 = $43.2

I didnt do this type of problem in a while but Im pretty sure its correct
A. Tell me if you want to know why
Answer:
+2 ft
Step-by-step explanation:
He descends -12 feet (negative descend is an ascend) so he ascends 12 feet
-14 + 12 = -2 so he needs to travel 2ft
a2-a1=1.25-1=0.25
a3-a2=1.5-1.25=0.25
a4-a3=1.75-1.5=0.25
a5-a4=2-1.75=0.25
a6-a5=2.25-2=0.25
As you can see, the difference in this sequence is constant and is equal to 0.25,
