An archaeologist in turkey discovers a spear head that contains 80% of its original amount of c-14. find the age of the spear head to the nearest year.

The age of the spear head to the nearest year is 1845 years

Step-by-step explanation:

We know that

half life time of C-14 is 5730 years

so, h=5730

we can use formula

now, we can plug value

an archaeologist in turkey discovers a spear head that contains 80% of its original amount of C-14

so,

we can plug it

now, we can solve for t

So,

The age of the spear head to the nearest year is 1845 years

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
