N represents the number in the sequence.
1st term: (1-2)/1^2=-1/1=-1
2nd term: (2-2)/2^2=0/4=0
3rd term: (3-2)/3^2=1/9
When you combine like terms you would get
2x^3+13x^2+26x+16
Have a great day!!!
Answer:
3,409.6 steps
Step-by-step explanation:
Given parameters:
Duration of the walk = 9.00am to 3.00pm
Number of steps walked = 20458 steps
Unknown:
Number of steps per hour =?
To solve this;
Number of steps per hour =
Duration = 9 am to 3pm = 6hrs
Now input the parameters:
Number of steps per hour = = 3,409.6 steps
Total number of steps per hour is 3,409.6 steps/hour.
You have two choices.
The minimum possible cost to operate your bat factory for a day is $390,
and there are two quantities of bats that both cost that much.
One possibility:
Produce no bats at all per day. Zero. Nada. None.
Cost = 0.06(0)² - 7.2(0) + 390 = $390 per day.
The other choice:
Produce 120 bats per day.
Cost = 0.06(120²) - 7.2(120) + 390
= 0.06(14,400) - 7.2(120) + 390
= 864 - 864 + 390
= $390 per day.
If you produce any other number of bats in a day ... more than zero
but not 120 ... then it will cost you more than $390 to operate the factory
that day.
