A biologist studied the populations of white-sided jackrabbits and black-tailed Jackrabbits over a 5-year period. He modeled the populations, in thousands, with the following polynomials where x is time, in years.

White-sided jackrabbits: 6.5x^2 – 8.7x + 5.9
Black-sided jackrabbits: 6.5x² + 9.2x + 1.2

What polynomial models the total number of white-sided and black-sided jackrabbits?

at home andrea has 1 2/3 kilograms of rice

step-by-step explanation:

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
