Answer:
Step-by-step explanation:
-We can use the exponential decay function to estimate the size after 13 years:
Where:
is the size after t years, t is the time, r is the rate of decay and 
the original size.
#We substitute and calculate as:
Hence, the forest covers after 13 years.
Written as a power of ten is 256.×10^0 or 2.56×10^1
Answer:the quotient of 16 and x=4
Step-by-step explanation:
Answer:
There are many examples the basics are also easy to remember.
Step-by-step explanation:
We can input these for the following equation.
x > 5
(x is greater than 5)
Then compare to - x < 5
(minus x is less than 5)
We try a sum
3x -2 ≤ 1
we can then balance subtract -2
3x ≤ -1
then divide by 3
x= -1 /3
We try another value
3x -2 ≤ 0
1 ≤ 3x
1/3 ≥ x
We can check that each equality fits and alter the number accordingly.
For the first one we are saying it is no greater than 1
For the second we say it is greater than zero.
We are able to prove both have the answer.
Just like when we look for negative percentages and count down we record this as we count in mental math.
