Answer:
For values when n<32 use fb(n) else use fa(n).
See explaination for details
Explanation:
Earlier when n=1 fa(n)=2000 while fb(n)=2. for n=2 fa(n)=2000*22 =2000*4=8000 while fb(n)=2*24=2*16=32. It is observed that fa(n) requires more time than fb(n) for small values.
Now, we will see when fb(n) crosses fa(n). This can happen only when fb(n) values equals or greater than fa(n)
therefore,
2000n2<=2n4
Solving equation we get n2>=1000 which can happen when n>=32.
So for values when n<32 use fb(n) else use fa(n)
Answer:
Explanation:
i) On a cold day, Capacity = (66 X 910 X 10∧-9) F
Charge, Q = (66 X 910 X 10∧-9) X 5050 = 0.30 Columb
Current, I= 5050/131013 = 0.039 Amp (where Resistance = 131013 ohms)
Time, t= 0.30/0.039 = 7.7 seconds
ii) On a humid day, Capacity = (77 X 910 X 10∧-9) F
Charge, Q = ( 77 X 910 X 10∧-9) X 5050 = 0.35 Columb
Current, I= 5050/6106 = 0.83 Amp ( where Resistance = 6106 ohms)
Time, t= 0.35/0.83 = 0.42 h or 0.42 X 60 mins = 25 mins
Answer:
Customer(1) - (1) Vehicle.
Explanation:
Cardinality is the mapping of entities or group of entities to a cardinal value. It tries to show the relationship between two objects like a cups in a shelf or plates in racks.
The car dealer in the question, sells one car to a customer and keep or prioritise the record of the main owner of the acquired vehicle. So the maximum cardinality assignment of the customer and vehicle is one (1) to one (1) mapping.
Answer:
It's simply a software that runs a computer's basic tasks, or functions, such as scheduling, running applications, and controlling peripherals.
