This is a perfect example of exponential decay. In this case the growth factor should be represented by a fraction, and it is! This forest, starting out with apparently ( 800? ) pine trees, has a disease spreading, which kills 1 / 4th of each of the pine trees yearly. Therefore, the pine trees remaining should be 3 / 4.
Respectively 3 / 4 should be the growth factor, starting with 800 pine trees - the start value. This can be represented as such,
- where a = start value, b = growth factor, t = time ( <em>variable quantity</em> )
____
Thus, the function 
can model this problem. The forest after t years should have P( t ) number of pine trees remaining.
Pretty sure it’s 36 if I’m wrong sorry
Answer:
the answer is x + 9
Step-by-step explanation:
3 times x equals 3x and 3 times 3 equals 9 -2X
you need to add like terms together
3x+2x=5x
and then 9 is by itself
so x+ 9 is the answer
hope this helps :-)
So for 1: You divide 1780 by 36 to get your answer. You will get a remainder but in this situation, we ignore it since you wouldn’t be able to wrap another gift completely
2: Divide 247 by 52. Again, you will get a remainder but in this situation we found up to the nearest whole because to be able to take all the kids, you would need another bus.
3: Divide 98 by 28. You will get a remainder, then you take that and divide it by 28, and simplify it, to get the fraction
