A biologist studied the populations of common guppies and Endler’s guppies over a 6-year period. The biologist modeled the populations, in tens of thousands, with the following polynomials where x is time, in years.
common guppies: 3.1x2 + 6x + 0.3
Endler’s guppies: 4.2x2 – 5.2x + 1
What polynomial models the total number of common and Endler’s guppies?
I am honestly surprised that you guys still don't know that everyone's math tests are different they do this to prevent cheating. Everyone has eight to ten personalized questions so google each individual question. Its worth your grade !!!!!
Ps: This only applies to math TESTS so cheat away on everything else
just add them up:
3.1x^2+6x+0.3
4.2x2-5.2x+1
----------------------
7.3x^2+0.8x+1.3
i luv scrolling thru these and just reading them
I got
1. 10x^4
2. -7y^5
3. -5x^2 - 8x + 2; quadratic trinomial
4. 7.3x^2 + 0.8x + 1.3
5. 71x^2
6. 15h^2 + 26h - 21
7. 12q^2 + 32q + 21
8. 12x^2 - 28x + 16
9. 80pi x^3 + 144pi x^2 + 84pi x + 16pi
10. 9x^2 - 42xy^4 - 49y^8
11. (x+7) and (x-4)
12. (x+10) and (x-3)
13. (x-3y)(x-7y)
14. (5x + 4)(2x-1)
15. (3x+5) and (x-6)
16. 46x^2 + 73x + 15
17. (w+6)^2
18. (t+9)(t-9)
obviously they change the questions but if any of the answers are possible answers on your questions, then put it in
I feel so dumb looking up the problem when all I had to do was read it more carefully XD.
Let me tell you all this 📢. Don't just write answers! When you write the answers make sure you write from what state your from cuz every state has different answering techniques. So If you have answers write the answers and write wherever you want as long as we can see it write the state name!! 👏
I ma on Unit 4 Lesson 11. Tests are hard!!!!!!!!!!!!!!!!!!!!!!!
6. 15h2+26h_21
7. 40w2+41+10
8. 12x2_28x+16
