The volume of the cone is 3.14 x 14 x 14
Answer:
m = 2
Step-by-step explanation:
take 2 pairs from x
choose (1,5) and (2,7)
it will be m = 5 - 7
and in the bottom 1 - 2 it's a fraction
m = -2/-1
the numerator and denominator can't be both negative
so your answer is m= +2
m= slope
rate of change= slope
Answer:

Step-by-step explanation:
that's your answer
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.
