Answer:
62.77 million gallons
Step-by-step explanation:
Given,
The function that shows rate of leaking oil per minute in after t hours,

∵ 1 hour = 60 minutes ⇒ 3 hours = 180 minutes,
Hence, the quantity of oil leaked out in the first 3 hours,



![=0.7[tan^{-1}(t)]_{0}^{180}](https://tex.z-dn.net/?f=%3D0.7%5Btan%5E%7B-1%7D%28t%29%5D_%7B0%7D%5E%7B180%7D)


= 62.77 million gallons
That would be written 5s+10
Answer:
Step-by-step explanation:
Number of hurricanes in year 2008 = 8
Number of hurricanes in year 2009 = 3
Decrease in number of hurricanes = 8 - 3 = 5
Percent of decrease in number of hurricanes =
= 62.5%
Number of hurricanes in year 2010 = 12
Number of hurricanes in year 2011 = 7
Decrease in number of hurricanes = 12 - 7 = 5
Percentage decrease in number of hurricanes =
= 41.7%
Decrease in numbers of hurricanes in year 2010 - 11 was same as in year 2010 - 11.
Percentage decrease in hurricanes were more in year 2008 - 09 than percentage decrease in year 2010 - 11.
Let y=0 to find the x-intercept(s).
0=−3x−4
Add 4 to both sides.
4=−3x
Divide both sides by -3
-4/3 =x (fraction)
Switch sides.
x=−4/3 (fraction)
Let x=0 to find the y-intercept(s).
y=−3×0−4
Simplify
y=−4
