Answer:
6 + 0.05
Step-by-step explanation:
To write a number in expanded form, you write each value of the digits by themselves. For example, let us say that that the number is 250.96 . To write in expanded form, you are essentially stretching out all the non-zero numbers, and keeping them separate (but in the same value), As in the example, we will write it out as expanded form:
250.96 = 200 + 50 + 0.9 + 0.06

Answer:
The age of the spear head is of 1938 yers.
Step-by-step explanation:
The amount of carbon 14 after years is given by the following equation:

In which Q(0) is the initial amount and r is the decay rate.
The half life of carbon 14 is 5700 years.
This means that 
So








So

We have to find:
t for which Q(t) = 0.79Q(0). So








Rounding to the nearest year.
The age of the spear head is of 1938 yers.
