Answer:
Step-by-step explanation:
Given that,
Cells are divided into two cell every 20mins, this implies that the half-life is 20mins
Initial population growth is 60cells
Growth rate r?
Population growth is modeled as
P(t) = Po•exp(rt)
Where,
Po is the initial growth at t= 0
Po= 60
P(t) is population at any time t.
Since the population doubles every 20mins(⅓hr)
Then, P(⅓) = 2×60 =120
Then, P(t) = 120cells
So, applying the formula
P(t) = Po•exp(rt)
120 = 60•exp(⅓r)
120/60 = exp(r/3)
2 = exp(r/3)
Take In of both sides
In(2) = r/3
Cross multiply
r = 3In(2)
r = 2.079 /hour
The growth rate is 2.079/hour.
2x2 + 5xy - 3y
there are three terms in the simplified expression
there is one negative term in the simplified expression

Answer:
The absolute change in the height of the water is 9.5 inches
Step-by-step explanation:
Given
--- length
--- width
--- height
--- the volume removed
Required
The absolute change in the height of the water
First, calculate the base area (b):
The height of the water that was removed is:
<em />
<em> i.e. the volume of the water removed divided by the base area</em>
The absolute change in height is:
20 degrees. i have a protractor, and its really helpful! you should use one.
