For the various values of X the values of Y are given as follows
X=-1; Y=3
X=0; Y=2
X=1; Y=3
X=2; Y=6
X=3; Y=11
Step-by-step explanation:
Step 1:
Let us consider the given expression as
Step 2:
Let us discuss the value of Y for the various values of X
If X = -1, Y = (-1)² + 2 = 3
If X = 0, Y = (0)² + 2 = 2
If X = 1, Y = (1)² + 2 = 3
If X = 2, Y = (2)² + 2 = 6
If X = 3, Y = (3)² + 2 = 11
If the area decreases by 8.5%, that leaves 100-8.5, or 91.5% of the forest remaining. So, at the end of 15 years, you have:
(.915)^15=.2638, or 26.38% of the forest left.
.2638 x 4200=1108 km² of the forest remains

3/5 x 3/5

You have to multiply the 2 numerators (top) and then the 2 denominators (bottom)
Answer:
240
Step-by-step explanation:
Since David has 60 fewer storybooks than Huiling, take the total number of storybooks, which is 460 and minus it by 60.
460-60=400
Now, there are 5 units, 5units=400
1unit=80
Since Jenny has 3 times as many storybooks as David, Jenny has 3 units, 3unit=80x3=240
