Answer:
The answer is...
f(x)=(x-3)+(x+3)
I think this is the answer. I haven't done this kind of math in a while so...
Answer:
7892 dolphins
Step-by-step explanation:
let P denote the dolphin population.
-Notice this is an exponential decay and is denoted as:
![P_t=P_oe^{-rt}](https://tex.z-dn.net/?f=P_t%3DP_oe%5E%7B-rt%7D)
Where;
is the population at time t- t is the time
- r is the rate of decay or decrease in population
is the initial population size.
#Given t=30yrs,
=20000 and r=3.1%, the population after 30 years is estimated as:
![P_t=P_oe^{-rt}\\\\=20000e^{-0.031\times 30}\\\\=7891.07\approx7892\ dolphins](https://tex.z-dn.net/?f=P_t%3DP_oe%5E%7B-rt%7D%5C%5C%5C%5C%3D20000e%5E%7B-0.031%5Ctimes%2030%7D%5C%5C%5C%5C%3D7891.07%5Capprox7892%5C%20dolphins)
Hence, the dolphin population after 30yrs is approximately 7892
Step-by-step explanation:
- Differentiate it.
- You will be given a value of x. Substitute into the differentiated equation
- use the formula for rate of change.
- You will find the answer
Formula:
![\frac{\alpha y}{\alpha x} =\frac{dy}{dx }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Calpha%20y%7D%7B%5Calpha%20x%7D%20%3D%5Cfrac%7Bdy%7D%7Bdx%20%7D)
Devin is buying 12 for $12 so for each he bought it was $1. If he’s selling them for the same price he bought them for (each) when he sells all 12 for $1, he will be left off with the same price he started off with. Devin is not making any profit. What i would do is sell them for $1.50, and then after each is sold, the total earnings would be $18.
