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,
MrEQ
Answer:
your answer is D
Step-by-step explanation:
- domain=x
- range=y
- range may have more than one but domain should only have one
Answer: The line starts at 1 positive, then from there go -4 (so go to the left) then 1 down from that point.
Step-by-step explanation: the problem is supposed to have been Y= -4/1 +1
Y - intercept t = 9/3 = 3
