Answer:
A. 4
Step-by-step explanation:
Pick two terms with consecutive x-values and find their ratio. That is the common ratio.
for x = 2 and x = 1,
r = 32/8 = 4
The common ratio is 4.
_____
You can check other pairs of terms if you want to confirm.
r = 2048/512 = 4 . . . . for x=5 and 4.
Answer:
The written form would be "Nine more than three times a number is greater than -18.
Step-by-step explanation:
To graph it, you must first solve for x.
3x + 9 > -18
3x > -27
x > -9
Now we can graph this by putting an open dot at -9 and then drawing an arrow to the right.
Answer:
Nine thousandth
Step-by-step explanation:
Only the nine thousandth is underlined I think, therefore you did not have to write out the words for the numbers before it

Answer:
24 trees per acre
Step-by-step explanation:
Let x be the optimal tree density per acre and y be the number of bushels yield per tree
Since for each unit change of x from 28 trees/acre, we have 2 unit change of y from 40 bushels per tree in the reversed direction
Change of x from 28 is x - 28
Change of y from 40 is y - 40
Therefore we have y - 40 = -2(x - 28) or y = 40 - 2(x - 28) = -2x + 96
The total bushels per acre should be y bushels/tree * x tree/acre. We want to optimize this. Substitute the above equation in for y and we have
To find the maximum value of this, we can take the first derivative and set it to 0
We know this is a maxima because 
. So T is maximum when x = 24 trees per acre
