Step-by-step explanation:
I had token the test
Cos(x°) = (√3)/2
cos⁻¹[(√3)/2] = x°, that means x° = 30°
Answer:
Step-by-step explanation:
Half life is the time taken by a radioactive substance to reduce of half of its original size
If the half life of radium is 1600, this means that the original radioactive substance N0 have reduced to N0/2 after 1600 years
if we are given N0 = 1000grams
The amount of the substance that will remain after 1600 years will be N0/2 i.e 1000/2 = 500g
<em>Hence 500 grams of radium will be left after 600years</em>
Well, the unit rate in the table is approximately 1.143 (8/7)
So, the only lines which have unit rate in between 1.143 and 2 are Line 3 (1.5) and Line 4 (1.2).
Answer:
4
