A=A₀

A/A₀=24%=0.24
0.24=

0.000121t=ln(0.24)
t=ln(0.24)/0.000121
=-11794.35
so painting is 11794 years old
Answer:
yes you have to use PEMDAS
Step-by-step explanation:
Answer:
Two points, one at 4 and one at 6.
Step-by-step explanation:
<u>Equations with absolute value
</u>
The absolute value of a number x denoted as |x| is a number with the same magnitude with a positive sign. When we know the result of an absolute value, we cannot know if the original number is positive or negative.
If |x| = a, a>=0, then x=a or x=-a
The equation to solve is |x – 5| = 1. If we apply the above criteria, then
x-5=1 or x-5=-1
Which gives us two possible solutions for x
x=6
x=4
The correct answer is
Two points, one at 4 and one at 6.
