Answer:
There are two results that could be consider the most accurate:
1. 16.110g
Step-by-step explanation:
Since the actual mass is 16.100g. The result above is within ±0.01. That is, the most accurate results should be within the range of ±0.01.
Hence;
The result that can be consider most accurate is:
=> 16.100±0.01 = [16.110]
All other results are at distance above ±0.01 from the actual values 16.100g
I don't agree because a pyramid's lateral face is a triangle, and he can only draw a prism if it's rectangular
Answer:
Initial amount is 523 grams
Amount after 100 years is 52 grams
Step-by-step explanation:
General exponential function for radioactive substances is given by
A(t) = Ao(1/2)^t/t1/2
Where,
A(t) is the amount remaining after t years
Ao is the initial amount of the radioactive substance
t is the number of years required for the radioactive substance to decay to A
t1/2 is the half-life of the radioactive substance
Comparing A(t) = 523(1/2)^t/30 with the general exponential function
Initial amount (Ao) = 523 grams
A(t) = 523(1/2)^t/30
t = 100
A(100) = 523(1/2)^100/30 = 523×0.5^3.333 = 523×0.0992 = 51.8816 = 52 grams (to the nearest gram)
