Answer : The substances half life in days is, 5.6 days.
Step-by-step explanation :
Half life : It is defined as the amount of time taken by a radioactive material to decay to half of its original value.
All radioactive decays follow first order kinetics.
The relation between the half-life and rate constant is:
where,
k = rate constant = 0.1235 per days
= half-life
Now put all the given values in the above formula, we get:
Thus, the substances half life in days is, 5.6 days.
Answer:
60cm^2
Step-by-step explanation:
1. turn triangle into rectangle measuring 15x8
2. find area of rectangle (area = base*height): 8*15 = 120
3. Find area of triangle (divide rectangle area by 2): 120/2 = 60cm^2
Answer:
it is possible to draw a triangle with angles 90 degree, 60degree and again 60 degree
For this case we have that by definition, the volume of a cube is given by:
Where,
- <em>s: Side of the cube
</em>
We have that the cube side is given by:
Therefore, replacing values we have:
Answer:
One way to write the volume of the cube is:
Answer:
I'm not entirely sure whether is X is with 4 under the fraction or not, so I put up both graphs results.
<h3 />
First one: F(x) = -(3/4)X +6
Second graph: F(x) = -(3/4X) + 6
