The half-life of carbon-14 is equal to 5730 years. The amount of substance with half-life h at any time t is equal to,
At = (Ao) x (1 - 0.5)^(t/h)
Substituting,
At/Ao = 0.67 = 0.5^(t/5730)
The value of t from the equation is 3310.6 years.
Phosphorus is, therefore important in cell division and development of new tissue.
It is also associated with complex energy transformations in the plant. Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness, stimulates tillering, and often hastens maturity.
Hopefully this helps :)
Answer:
Choose distinct parallel lines.
Explanation:
They represent two parallel lines. The slopes are going to be the same in each line . Put the x value on the opposite side of the equal sign.
y = - 5x + 3 The slope is - 5
10x + 2y = - 6 Subtract 10x from both sides
2y = - 10x - 6 Divide by 2
y = -10x/2 - 6/2
y =-5x - 3
That minus three is the problem. You have 2 different y intercepts. That means that you have 2 parallel lines.
