Answer:
Option A
Step-by-step explanation:
The complete question is attached here
The rate of increase of bacterial population be K
As we know
where Y is the final population. In this case it is 1000
K is the rate of increase of population i.e 3 times per hour
T is the time in hours
Y0 is the initial population = 5
Substituting the given values, we get -
Taking log on both sides, we get -
ln = ln
T = 2.084 hours
hence, option A is correct
Answer: The fusion of hydrogen to form helium changes the interior composition of a star, which in turn results in changes in its temperature, luminosity, and radius. Eventually, as stars age, they evolve away from the main sequence to become red giants or supergiants.
Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, </em><em>b</em><em>)</em>
<em />
The fromual of a slope:
<em>(x₁, y₁), (x₂, y₂)</em><em> - points on a line</em>
<em />
We have the points from the graph:
(0, 1) → <em>b = 1</em> and (3, 3).
Calculate the slope:
Finally we have the equation of a line:
Answer: 615
