Answer:

the equation for the mid line is y = -2.5

Step-by-step explanation:

The given equation is

$f(x)=3cos(x)-2.5$

On comparing this equation with $f(x)=Acos(Bx+C)+D$

A = 3

B = 1

C = 0

D = -2.5

The mid line for the equation is

y = D

Substituting the value of D

y = -2.5

Thus, the equation for the mid line is y = -2.5

Answer:

Step-by-step explanation:

I really hope you know how to use your calculator to find regression equations, because in this forum it is impossible to teach you how to do that. I ran the data through my calculator and got the exponential equation as

$y=1963.56(1.14)^x$ which means at 4 hours, we started with 1963 bacteria and it is growing at a rate of 114% each hour. Since we started out with an x value of 0, and that value represents the number of bacteria after 4 hours, then time 0 is 4 hours, which means that time 12 is 16 hours. We replace the x in the equation with a 12 and do the math:

$y=1963.56(1.14)^{12$ which gives us, in the end,

y = 9460
