Determine an equation of a perpendicular line but with the same y intercept
Open bracket
A linear equation is represented with:
Where
By comparison:
So, the slope of is m
Because the new line is perpendicular to , the relationship between their slopes is:
Where
slope of the first equation
slope of the second equation
Substitute m for 
in
Hence, the slope of the new equation is: 
From the question, we understand that they have the same y intercept.
So, the equation of the new equation is:
Answer:
B and C
Explanation:
B. In a given rock sample, the amount of Silicon-32 isotopes gets divided in half about every 170yrs.
This is the concept of half-life. Half life is the time take for half of a radioactive isotope to disintegrate. The shorter the half life the faster the isotope disintegrates.
From the question, we were told that it would take 170yrs for half of the isotope of Silicon to disintegrate to Phosphorus. This is the half life.
C. The half life can be used to determine the amount of Si-32 that has decayed from the time closure temperature was reached.
The closure temperature is very important in radioactivity. It is the temperature at which a system has cooled and there is no resulting disintegration of parent and daughter isotopes.
From first order kinetics, we know that the rate at which radioactive elements decay at any time is directly proportional to the number of radioactive atoms present. A knowledge of the half life helps to figure out the number of atoms that has decayed in time.
Answer:
Because of favorable climatic condition..
easy to access to the market...
better transportation facilities ..
easy connectivity
Explanation:
According to von thunen's model, the one that would be produced most profitably on the ring farthest from the epicenter would be : B. Sheep
Von Thunen's model divided earth's region into 4 parts depending on what product that would be most profitable. according to this model , the farthest from epicenter is most suitable for Ranching/Animal Products
Hope this helps
