Answer:
100 1/4
Step-by-step explanation:
You haven't provided any value, but I can tell you the solution set for the inequality.
First of all, expand both sides:
![-3x+12 > 6x-6](https://tex.z-dn.net/?f=%20-3x%2B12%20%3E%206x-6%20)
Add 3x to both sides:
![12 > 9x-6](https://tex.z-dn.net/?f=%2012%20%3E%209x-6%20)
Add 6 to both sides:
![18 > 9x](https://tex.z-dn.net/?f=%2018%20%3E%209x%20)
Which is of course equivalent to
![9x < 18](https://tex.z-dn.net/?f=%209x%20%3C%2018%20)
Divide both sides by 9
![x < 2](https://tex.z-dn.net/?f=%20x%20%3C%202%20)
So, every number smaller than 2 is part of the solution of this inequality.
Answer:
![1679.60\ km^2](https://tex.z-dn.net/?f=1679.60%5C%20km%5E2)
Step-by-step explanation:
-We can use the exponential decay function to estimate the size after 13 years:
![P_t=P_oe^{-rt}](https://tex.z-dn.net/?f=P_t%3DP_oe%5E%7B-rt%7D)
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:
![P_t=P_oe^{-rt}\\\\=4600e^{-13\times 0.0775}\\\\=1679.60](https://tex.z-dn.net/?f=P_t%3DP_oe%5E%7B-rt%7D%5C%5C%5C%5C%3D4600e%5E%7B-13%5Ctimes%200.0775%7D%5C%5C%5C%5C%3D1679.60)
Hence, the forest covers
after 13 years.
Answer:
Step-by-step explanation:
n²+2n+1 = (n+1)(n+1)
n²-8n-9 = (n+1)(n-9)
the least common denominator for these two rational expressions is :
(n+1)(n-9)
