The exponential function is often used to model the growth or decay of a population
The population size of the yeast cell after 3 hours is 6.24 million
The given parameters are:
a = 3.1M --- initial number of cells
r = 0.4425 per hour --- rate
The nth term of an exponential function is:
f(n) = a(1+r)^n-1
After 3 hours; n = 3
So, we have:
f(3) = a(1+r)^3-1
Substitute values for a and r
f(3) = 3.1 (1+0.4425)^3-1
f(3) = 3.1 ( 1.4425)^2
f(3) = 6.24
Hence, the population size of the yeast cell after 3 hours is 6.24 million.

Answer:
SOrry i cant heklp u
Step-by-step explanation:
Answer:
Y = 26
W = 73
X = 81
Step-by-step explanation:
∠W = 3∠Y - 5
∠X = ∠W + 8 = 3∠Y - 5 + 8 = 3∠Y + 3
∠Y + ∠W + ∠X = 180
substitute in the formula
Y + (3Y - 5) + (3Y + 3) = 180
7Y -2 = 180
7Y = 182
Y = 26
W = 3(26) - 5 = 73
X = 73 + 8 = 81
7, as the square root of 49 is 7
(The sides would be equal, and so the area would be one side squared)
Answer:
90
Step-by-step explanation:
50% of 180 = 90%
90% is the answer.
