19 yards divided by 2.5 minutes.
=19/2.5
= 7.6 yards/minute
Consider the arithmetic series 
Let t=1 in the given series, we get
first term =
= 3-4 = -1.
Let t=2 in the given series, we get
second term =
= 
Let t=3 in the given series, we get
third term = 
Now, let t=18 in the given series, we get
last term = l = 
We get the series as
-1, 2, 5,..... 50
Sum = 
= 
= 
= 441
Therefore, the sum of the given arithmetic series is 441.
Well i got a family of to of me and my dad we take about a week but my moms fam with my 3 sisters plus her boyfriends kids there would be 5 and they drink i would say 2 gallons a week three at most
14. The equation would be -16t^2+60t+7 To find the maximum point plug in values into the equation -b/2a to find the axis of symmetry, and plug that number in for t.
b=60, a=-16
-60/-32=t=1.875
-16(1.875)^2+60(1.875)+7=63.25
Maximum point: (1.875,63.25)
The ball will land after about 3.86 seconds
