Average rate of change = (x(4) - x(2))/(4 - 2) = ((4 + 2(4)^2) - (2 + 2(2)^2))/2 = ((4 + 2(16)) - (2 + 2(4)))/2 = ((4 + 32) - (2 + 8))/2 = (36 - 10)/2 = 26/2 = 13.
Therefore, average velocity is 13 m/s
36 should be added to both sides because 12/2= 6 then you square 6 to get 36 and that should be it.
Answer:
3
Step-by-step explanation:
First we must find the total boxes of pens
15 + 9 = 24
Then we can divide the total cost by the total number of boxes of pens
$72 / 24 boxes = 3
432 lb = 195.95 kg
All you have to do is use the conversion rate for pounds to kilograms. Have a nice day :)
1km=1000 meters so 2km=2000, and if you have 4 of the races you multiply 4 by 2000 which gives you 8000 meters
4*2000=8000
