Since y = -3/4 is a horizontal line only passing through 0.7 on a graph, you need a positive line that starts at -8 on the y-axis and goes to 3 on the x-axis.
To find your answer, you have to remember in y=mx+b, m is your slope and more importantly, b is the y-intercept.
Since you need a line that goes through both 3 and -8, we already know the b should be -8.
Now all you have to do is find the slope, which is just your directions to get to 3. The coordinates are (0,-8), so to get from -8 to positive 3 you need to go up 8 over to the right 3.
So you should have y = 8/3x-8. Also, look at the graph above.
Answer:
A rock with a half-life of 5,280 years having 1/8th of the parent material left will be 15,840 years old.
Explanation:
The half-life of a material is the time needed for only half of the parent material to be left, while half has is gone, or rather has disintegrated. The half-life is used further into the falling apart of the parent material though, with the same principle being applied. Practically, from the 1/2 of the parent material being left, the half-life of it would mean 1/4 of the parent material being left, and from that 1/4, the half-life would be at 1/8 of the parent material being left, and so one, by simply dividing in two.
In this case, having a half-life of the rock of 5,280 years, we will simply need to add that amount of years on every next phase. So, the half-life is 5,280 when 1/ of the parent material is left. When 1/4 of the parent material will be left we will have an age of 10,560 years, while when only 1/8 is left, we will have 15,840 years of age for the rock.
Answer & Explanation:
People depend on the environment for fishing. Many Greenlanders fish in the icy cold water. ... They adapt to the environment by wearing clothes that suit the temperatures and the seasons. Because Greenland has an arctic climate, people need to wear lots of layers in the winter as well as big coats or boots.
