d = √(9-2)²+(4-4)²
d = √7²+0²
r = 3,5
____________________
(x-a)² + (y-b)² = r²
(x-5.5)² + (y-4)² = 3,5²
(x-5.5)² + (y-4)² = 12.25
Step-by-step explanation:
P(W^c) = 1-3/5
=5-3/5 =2/5
Answer:
12 players on each team
Step-by-step explanation:
144 players/ 12 teams = 12 players on each team. Hope it helps!
The volume of the gallon is 6000 gallon
the rate of water flow per min is f(t)=300t^2
a] amount of water that flowed in the first 7 minutes=7/60 hours will be:
f(7)=300(7/60)^2
solving the above we get
f(7)=7/12 gallons
b] The time taken for the tank to be empty will be as follows:
amount of water that will flow out for the tank to be empty will be 6000 gallons
thus,
6000=300t^2
this can be simplified to
20=t^2
t^2-20=0
solving this we get:
t=-2√5 or 2√5
the time taken for the tank to be empty will be t=2√5 hours=5.4721 hours
