I dont know wish I could help, srry.
Hello,
I would be happy to help.
For Part A, you just count the number of terms, there are 3. So, it is a trinomial.
For Part B, you look at the highest exponent value, it is 2. So it is a second degree polynomial.
For Part C, you have to sub in the values for each year. You are looking for the number of years since 1930, so subtract 1930 from each year.
2020 - 1930 = 90
2030 - 1930 = 100
Then, sub in those values into the given expression to find the density.
0.005(90)^2 - 0.127(90) + 1 = 30.07
0.005(100)^2 - 0.127(100) + 1 = 38.3
Remember to use the order of operations!
Good luck,

Answer:
5 times shorter
Step-by-step explanation:
The period is the time it takes for one cycle to complete, or in this case, one breath. Since person A is breathing 5 times faster, the time per breath is 5 times shorter.
Answer:
It is a growth.
Step-by-step explanation:
If the number in parenthesis (exponential base) is greater than 1, then it is a growth. If it is between 1 and 0, then it is a decay.
