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: 684
Step-by-step explanation:
95% of 720
Move decimal point two places to the right.
0.95 * 720 = 684
Answer:
1
Step-by-step explanation:
1
So for 9, to graph all you need to do is start at the origin (0,0) and go up 4 and over (right) 1.
Answer:
x = 1
Step-by-step explanation:
Note that the two lines are of equal length
4x-1 = x + 2
3x = 3
x = 1
