Answer:
9990 years
Step-by-step explanation:
The exponential function with given values filled in can be solved for the unknown using logarithms.
__
Q(t) = 12 = 36e^(-0.00011t)
1/3 = e^(-0.00011t) . . . . . . divide by 36
ln(1/3) = -0.00011t . . . . . . take natural logs
t = ln(1/3)/(-0.00011) . . . . divide by the coefficient of t
t ≈ 9990 . . . years
Answer:
18
Step-by-step explanation:
product means the sna=swer of a multiplication problem, so 9x2=18
She walks 2/4 of a mile in 1 hour
Answer:
One statement that is true is that it equals 50
Step-by-step explanation:
15 + 10 = 25 people
