Answer:
-9/14
Step-by-step explanation:
This is my simplest-
Do the keep-change-flip method for this problem (and also any problem involving this)
KEEP -3/8
CHANGE the division sign to multiplication
FLIP the last fraction. 7/12 to 12/7
Now solve the problem by multiplying the fractions
-3/8 × 12/7 =
-3 × 12 = -36
8 × 7 = 56
-36 / 56 =
Simplify it by dividing the numerator (up of the line) and denominator (below the line) to get -9/14

Answer:
<h2>
The population will reach 1200 after about 2.8 years</h2>
Step-by-step explanation:
The question is incomplete. Here is the complete question.
The population of a certain species of bird in a region after t years can be modeled by the function P(t) = 1620/ 1+1.15e-0.42t , where t ≥ 0. When will the population reach 1,200?
According to question we are to calculate the time t that the population P(t) will reach 1200.To do this we will substitute P(t) = 1,200 into the equation and calculate for the time 't'.
Given;

The population will reach 1200 after about 2.8 years
