2 weeks, because the first week the second plant will grow to 6 inches and the first plant will grow to 7, the next week the first plant will be 8 inches and so will the second plant.
Answer:
197.2 million
Step-by-step explanation:
The appropriate exponential equation for the population is ...
p(t) = 172.0e^(0.019t)
Then we can compute for t=7.2:
p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2
7.2 minutes from now, the population will be about 197.2 million.
___
For continuous growth (or continuous compounding), the exponential formula is ...
f(t) = (value at t=0)×e^(rt)
where r is the growth rate in one unit of time, and t is the number of time periods.
Answer:
C. -3(√y)(∛x²)
Step-by-step explanation:
Recall the rule for exponents with fractions. The numerator represents the power the variable is raised by, and the denominator represents the which root will be taken.
y^1/2 equals √y
and x^2/3 equals ∛x²
So the answer is -3(√y)(∛x²)
