Answer:
y=3x-7
Step-by-step explanation:
y=m*x + b : equation of a line.
m= slope = rise over run = 3/1 =3
b = y-axis intercept = -7 (where the line crosses the y-axis)
Hi there
The exponential growth equation of
the number of bacteria doubles each hour is
N=2000 (2)^t
Where t is the number of hours
T=7 hours
So the number of bacteria after 7 hours is
N=2,000×(2)^(7)
N=256,000....answer
Good luck
Use the interior angle theorem
(7-2)180 = 900
900 / 7 = roughly 128.6
your answer is C
Explanation:
It means the result of your calculation doesn't differ from the actual value by more than a factor of 3 (or "something").
For example, suppose you're estimating the volume of a lake. You estimate it to be 100,000 acre-feet. If its actual volume is 265,000 acre-feet, your estimate is within a factor of 3 of the correct volume. (You are too low by a factor of 2.65.)
If your estimate were 700,000 acre-feet, you would still be within a factor of 3 of the correct value. (You would be too high by a factor of 2.64.)
___
This sort of tolerance allowance is usually specified for things that are difficult to estimate. A factor of 3 is generous, but requires you have a pretty good guess as to many of the parameters involved. For example, it may be unlikely you could estimate the number of grains of sand on a beach within such a factor. On the other hand, you could probably easily estimate the number of candies in a jar within that tolerance.
