A population of a particular yeast cell develops with a constant relative growth rate of 0.4225 per hour. The initial population

Ksju [112]

Answer: The population after 3 hours is 13.9 mill.

Step-by-step explanation:

When we have an exponential with:

A = initial population.

r = constant relative growth rate:

t = time.

The function that models this is:

P(t) = A*e^(k*t)

In this case we know that:

A = 3.9 mill.

r = 0.4225 1.

Then the function that models the population of this yeast cell is:

P(t) = (3.9 mill)*e^(0.4225*t)

where t represents the time in hours.

Then if we want to know the population after 3 hours, we should replace t by 3.

P(3) = (3.9 mill)*e^(0.4225*3) = 13.85 mill.

And we want to round our answer to one decimal place, then we must look at the second decimal place, we can see that is a 5, so we should round up.

The population after 3 hours is 13.9 mill.

tesfa = x

dad = 4x

mom= 4x-1

x+4x+4x-1=101

9x+1=101

9x=100

zavuch27 [327]

Answer:

Slope = - $\frac{7}{3}$

Y-intercept = 4

Step-by-step explanation:

-> See attached

-> This equation is in slope-intercept form.

[] When we use y = mx + b, the m is the slope and the b is our y-intercept.
