Abiologist studied the populations of black bear and brown bears over a 10-year period. the biologist modeled the populations, in thousands, with the following polynomials where x is time, in years. black bears: 2.3x2 – 5.6x + 2.3brown bears: 2.4x2 + 7.2x + 0.97what polynomial models the total number of brown and black bears? a. 4.7x^2 + 1.6x + 3.27 b. 4.7x^2 – 1.6x – 3.37 c. 4.7x^2 + 1.6x – 3.37 d.4.7x^2 – 1.6x + 3.37

Abby is preparing fruit punch for her party. she starts with a bowl filled with liquid that has 1/2 fruit juice and 1/2 sprite, but she decides it's too fruity. so she pours out 1/4 of the liquid, and then fills the bowl up again with sprite. what fraction of the punch is now sprite?
