Answer:
2.81 and 0.3 are two decimals that give a product of 8.43 which is close to 8.4
Step-by-step explanation:
let consider a decimal number 0.3
now consider another decimal number 2.81
now if we multiply these two numbers then we get 8.43 which is also a decimal number and it is close to 8.4.
Given the equation:
You know that the radioactive substance has this half-life (in years)
And:
Therefore, you can rewrite the equation in this form in order to find "k":
Solve for "k":
We know that: sin Ф = cos(π/2 - Ф) ↔ sin Ф = cos(90° - Ф)
Then:
sin 42° = cos(90° - 42°) = cos 48°
IF sin 42° = 2/3, the cos 48° = 2/3
