Answer:
226.78579
Step-by-step explanation
first, find k in 90(3^kx)
90(e^0) = 90 [when time is 0 years, the population is 90]
180=90(e^k3), 2=e^3k
ln2 = 3k, k=(ln2)/3
90(e^4(ln2)/3) = 90(e^ln(16)/3)
it is about 226.78579
That depends on how much water you use, for instance 3 cups of water to 1 cup of cleaner.

Answer:
t = 6.67 seconds
Step-by-step explanation:
Given that,
The distance of Moon from Earth,
The speed of the spacecraft,
We need to find the time it take this spacecraft to fly to the moon from earth. Let the time is t.
We know that,
Speed = distance/time
So, the required time is equal to 6.67 seconds.
