Plugging -6 in for x, we get -2sqrt(-6-7+1)=sqrt(something negative) which is clearly not possible.
Plugging -6 in for f(x), we get -6=-2sqrt(x-7+1) and 3=sqrt(x-7+1). Squaring both sides, we get 9=x-7+1 and by adding both sides by 6 we get 15=x, therefore having (15,-6) and proving that -6 is in the range, but not the domain (B)
Answer:
After 9 years, the population reach 4000.
Step-by-step explanation:
The given function P(t) represents the size of a small herbivore population at time t (in years).
We need to find the number of years after which population reach 4000.
Substitute P(t)=4000 in the above function.
Divide both sides by 1000.
Taking ln on both sides.
![[\because \ln e^x=x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20e%5Ex%3Dx%5D)
Divide both sides by 0.16.
We need to find the number of years. So, round the answer to the next whole number.
Therefore, after 9 years, the population reach 4000.
Possible genetic combinations of offspring are:
<span>
- A1A3
- A2A3
- A1A4
- A2A4
</span>
Therefore, each genotype has a probability of 1/4
The probability of having thesame genotype the second time is 1/4 * 1/4
= 1/16
The probability that both offsprings will have the same genotype is 1/16

Step-by-step explanation:
LIVE AND LET me know if you want me to send you
Answer:
True.
Step-by-step explanation:
I don't know the explanation behind any of it, but a negative number, when multiples by another negative number, is always positive.
