The domain is the limits of the function. Since time doesnt go negative, start with 0. At time 0, the height is
-16(0)^2 + 144 = 144ft
Then, solve for t to find the upper limit for t, which is when the height is zero (since you're dropping the object).
-16t^2 + 144 = 0
-16t^2 = -144
t^2 = 9
t = sqrt(9)
t = 3
The domain is 0 to 3 seconds.

Elliot drove 31.2 miles per gallon of gasoline
The slope is the rate
words per minute
we can do
540 words in 3 minutes
divide by 3
180 words in 1 minute
thea=180wpm
elanor=225wpm
elanor>thea
and 225*2=450
answers are
Thea reads 180 words per minute.
Eleanor reads 450 words every 2 minutes.
After 1 hour of reading, Eleanor reads more words than Thea.
