A balloon with a small leak loses 1% of its volume each day. If originally contains 24 liters of gas, what is the volume at the
Georgia [21]
ANSWER

The volume at the end of one week will be 22.32 liters.

EXPLANATION

If the balloon with a small leak loses 1% of its volume each day, then by the end of one week, it will lose 7℅ of its volume.


If the balloon originally contains 24 liters of gas, then this corresponds to 100%.

The volume at the end of one week will correspond to (100-7)%=93%


The volume at the end of one week is

=  \frac{93}{100}  \times 24


=  \frac{2232}{100}
= 22.32 \: liters

MatroZZZ [7]
Basically when the object hits the ground, f(t) is equal zero. So all you need to do is to solve the quadratic equation:
-5t^2 + 20t + 60 = 0

D = b^2 - 4ac = 20^2 - 4 × (-5) × 60 = 400 + 1200 = 1600

t1 = (-b + sqrt(D)) / 2a = (-20 + 40) / (-10) = -2
t2 = (-b - sqrt(D)) / 2a = (-20 - 40) / (-10) = 6

Since time can't be negative, our solution is t2.

So the object will hit the ground in 6 seconds.
