Answer:
$13,310
Step-by-step explanation:
Your formula is A=P(1+r/n)^nt
P is what you put into the account = 10,000
R is the interest rate as a decimal = .1
T is the time in years= 3
In the formula this would be:
10,000(1+.1/1)^3
Use a calculator.
The answer is 13,310
The distance between the two coordinates is 9.434
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
