A biologist studied the populations of geckos and salamanders at Huntington Beach State Park over a five year period The biologist modeled the populations, in thousands, with the following polynomials where x is time, in Geckos: 9.77-0.8+23
Salamanders: - 1. 12° +7.72 +5.4
What polynomial models the total number of geckos and salamanders at gntington Beach State Park?
8.62? +6.9.r - 7.7
O 8.622-6.9.r +7.7
8.6 + 6.9 +7.7
8.62 - 6.9z - 7.7

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

it shoild be o
