4. a biologist 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 + 2.3 brown bears: 2.4x2 + 7.2x + 0.97 what polynomial models the total number of brown and black bears? (1 point)
4.7x2 + 1.6x + 3.27
4.7x2 – 1.6x – 3.37
4.7x2 + 1.6x – 3.37
4.7x2 – 1.6x + 3.37

The modeled of total population of bear is

A is correct.

Step-by-step explanation:

A biologist studied the populations of black bear and brown bears over a 10-year period.

Modeled the population of Black Bear:

Modeled the population of Brown Bear:

We need to find the population modeled of the total number of brown and black bear.

Total population of bear modeled by h(x)

Combine the like term

Hence, The modeled of total population of bear is

answer:

3 bags of apples and 2 bags of oranges.
