Answer: 45 minutes
Step-by-step explanation:
the first pump takes care of 300 gallons so we need to worry about the remaining 900 gallons. the second pump removes 20 gallons per minute so all u have to do to find how many minutes it would take is divide 900 gallons by 20 gallons a minute which gives you 45
it will take 45 minutes to completely drain the pool
The whole number portion is always the number to the left of the decimal. In this case it is 5. You have to be careful what you say if you are working in scientific notation.
For your second question 0.261 is the decimal portion. If the only part present was 0.261, then 0 is the whole number portion, believe it or not. Nice question. You can learn a lot from it.
I'm not really sure what you're asking, but if you want to calculate the first two terms of the sequence after a1, then here's the answer:
If a1=2, then a2 = -3(a1 - 1)^2 = -3(2-1)^2 = -3*(-1)^2 = -3*1 = -3.
Then, a3 = -3(a2 - 1)^2 = -3(-3-1)^2 = -3(-4)^2 = -3*16 = -48.
I'm sorry if this is not what you wanted.
