A population grows according to the logistical model p(x) = 1250/1+e^-2x ,where x is measured in seconds. According to this model, at what time x will the population reach 800?
A. 2 In 2 + In 3 seconds
B. In 2 - In 3 seconds
C. 2 In 2 - 3 In 3 seconds
D. 2 In 2 - In 3 seconds

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
