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.
Answer:
between 3 and 4
Step-by-step explanation:
to find 19/6 located where on the number line
first we need to convert 19/6 to decimal
19/6 = 3.166...
so lets now see where 3.166 lies
it first lies between 3.160 and 3.170
but we need integer
so we go deeper and see
it lies between 3.100 and 3.200
and then we need to go more deeper to get an integer not decimal
now it lies between 3 and 4
I'm not 100% sure but my best guess would be a rectangle. ( do not give brainliest if wrong, i wanna make sure its right)
Answer:
A = 0/(0 x 7y³)
Let's see the denominator: 0 x 7y³ = 0
=> Whenever the denominator is 0, A is undefined, neither a positive number or negative number
Hope this helps!

Answer:
A, C, E
Step-by-step explanation:
As long as all the 3 letters(D, K, and M) are included, it should be a valid name. These are the 3 points in the triangle afterall.
