The process of finding which prime numbers you need to multiply together to get a certain number. ex: 21=7x3 20=2x2x5
Answer:
The estimated age of the skull is 39118 years.
Step-by-step explanation:
The amount of the substance after t years is given by:
In which A(0) is the initial amount, and r is the decay rate.
The half-life of carbon-14 is about 5600 years.
This means that 
. We use this to find r, or 1 - r, to replace in the equation. So
![\sqrt[5600]{(1-r)^{5600}} = \sqrt[5600]{0.5}](https://tex.z-dn.net/?f=%5Csqrt%5B5600%5D%7B%281-r%29%5E%7B5600%7D%7D%20%3D%20%5Csqrt%5B5600%5D%7B0.5%7D)
So
Only 2% of the original amount of carbon-14 remains in the burnt wood of the campfire.
This is t for which 
. So
The estimated age of the skull is 39118 years.
Answer:
16 workers are required to complete the work in 45 days...
Step-by-step explanation:
12 workers are required to complete the work in 60 days
so... 60*12=720 workers are required to complete the work in 1 day
Hence,
720/45 = 16 workers are required to complete the work in 45 days.
Answer:
(-7, 8)
step-by-step explanation:
- original coordinates of B: (-9, -8)
if translated two units horizontally, there will be change in x axis
- new coordinates: (-9+2, -8) → (-7,-8)
if reflected over x-axis, use the formula: (x,y) → (x, -y)
- new coordinates: (-7, -(-8)) → (-7, 8)
Answer:
8 units
Step-by-step explanation:
The origin is 0, so -8 is 8 units away from the origin.
