The lynx population on a small island is observed to be given by the function P(t)=120t−0.4t^4+800

where t is the time (in months) since observations of the island began.

(a) The maximum population attained at

t=
months.

The maximum population is

P(t)=
lynx.

(b) When does the lynx population disappear from the island?

a 10 percent increase

-81 -56 -27 0 81

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
