Answer:
434,470 gallons
Step-by-step explanation:
The exponential equation for the volume v remaining after t hours can be written as ...
v(t) = (initial amount)×(decay factor)^(t/(decay time))
v(t) = 500,000×(1 -10%)^(t/3)
Then after 4 hours, the remaining volume is ...
v(4) = 500,000×(0.90^(4/3)) ≈ 434,470 . . . . gallons
_____
<em>Comment on the form of the equation</em>
The decay factor is related to the decay rate by ...
decay factor = 1 - (decay rate)
and the decay time is the time applicable to that decay rate. Here, the rate is 10% every 3 hours, so the decay time is 3 hours for a decay rate of 10%.

Answer:
4.4 in
Step-by-step explanation:
If a radius is perpendicular to a chord, it bisects that chord. You can use Pythagorean theorem here
Once solved you'll find x to be roughly 4.4 in
Answer:
Step-by-step explanation:
GIVEN: Rosie went on a hiking trip. The first day she walked kilometers. Each day since, she walked of what she walked the day before.
TO FIND: What is the total distance Rosie has traveled by the end of the day.
SOLUTION:
Rosie walked first day
Rosie walked on second day
Rosie walked on third day
this forms a GP with first term and common ratio
General term of GP
Sum of GP
Hence Rosie traveled total
