Wouldn't this be in literature?
X^2-48 can be viewed as a difference of squares which would factor to:
(x+√48)(x-√48)
So b=√48
Answer: x = -8
Step-by-step explanation:
You have to expand the expression so you multiply 1/2 by 2, 3x and -6 this gets x to be -8
Answer: 49929 years ago
Step-by-step explanation:
Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms
To calculate the time, we will use exponential formula
R% = e^ -kt
Where t = number of years
0.25/100 = e^- 0.00012t
Log both sides with natural logarithm
Ln0.0025 = lne^-0.00012t
-5.9915 = -0.00012t
t = 5.9915/0.00012
t = 49928.9 years
Approximately t = 49929 years
