Answer:

20 gallons of water is leaked after an hour.
Step-by-step explanation:
Water is leaking at a constant rate of 1/3 gallon per minute.
a) We have to write a linear equation in two variables that show the amount of water, w, in gallons, that is leaked from the faucet after t minutes.
So, the equation is
......... (1) (Answer)
b) Now, if t = 1 hour i.e. 60 minutes, then from equation (1) we can write
gallons.
Therefore, 20 gallons of water is leaked after an hour. (Answer)
Answer:
9
Step-by-step explanation:
10+ -7
3
3 = 9/3

The given model would make the least sense to use for x=-2.75.
the given function is:

a quadratic relationship,
where
h is the height in feet
x is the time in seconds
<h3>what is kinetic energy?</h3>
Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.
h(-2.75) = 
h(0.25) = 

h(1.75) = 
h(25) = 
therefore, x=-2.75 this model would make the least sense to use
