Answer:
(- 3, 2 )
Step-by-step explanation:
The solution to the system is at the point of intersection of the 2 lines.
The lines intersect at (- 3, 2 )
Thus the solution is (- 3, 2 )
Answer:
He should have done 8^2 + 15^2= x^2 because the hypotenuse is always the longest side and in Pythagorean theorem C represents the longest side
It has been given that exactly 0.1 of the radioactive nuclei in a sample decay each hour. Thus, after n hours, the fraction of nuclei is given by the model expression: .
Now, to find the value of n equal to one half-life, all that we need to do is to equate the above expression to half or 0.500 (to the indicated places of decimal) and solve for n.
Thus, we will get:
Taking the log to the base 10 on both sides, we get: (Please note that we can take the log to any base)
Dividing both sides by log(0.900), we get:
hours
Therefore the value of n equal to one half-life is 6.579 hours.
