Answer:
- 5-hour: 0.5277
- 1-hour: 0.8800
Step-by-step explanation:
The decay factor for time t can be written as ...
0.2785^(t/10)
Then the 5-hour decay factor is ...
0.2785^(5/10) ≈ 0.5277
and the 1-hour decay factor is ...
0.2785^(1/10) ≈ 0.8800
Notice that based on the diagram, all of the sides of the triangle are the same length. (The dashes on the sides of the triangle show that the sides are of congruence.) This means that the triangle is an equilateral triangle. An important thing to note about equilateral triangles is that they all have angles of 60°. All angles in equivalent triangles are 60°.
This means that we can set
equal to 60 to solve for
