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

Answer: 1/6 + 2/3 = ?
Step-by-step explanation and answer: To add fractions, you must have commen denomionators, so what is the least commen multiple of 6 and 3? You should say 6 because they are the lowest number that are equal, and the same. You should have 1/6 + 4/6=? You do not add the denomionators, they are still the number 6. But you add the numerators, so 4+1=5, so your answer is 5/6.
