6 is the cube root of 216.
I hope this helps! :D
Yay, derivitives
I'mma ignore that x is the shorter side because I don't know which one has to be shorter yet
we need to find the max area
but with 3 sides
area=LW
let's say the sides are z and y
zy=area
and the relatiionship between them is
hmm,
z+2y=1200
because one side has no fencing
so
z+2y=1200
solve for z
z=1200-2y
sub for z in other
(1200-2y)(y)=area
expand
1200y-2y²=area
take derivitive
1200-4y=dy/dx area
max is where dy/dx goes from positive to negative
solve for where dy/dx=0
1200-4y=0
1200=4y
300=y
at y<300, dy/dx<0
at y>300, dy/dx>0
so at y=300, that is the max
then
z=1200-2y
z=1200-2(300)
z=1200-600
z=600
so then
z=600
y=300
300<600
so the shorter side would be y
so then we see our choices and noticed that
erm
I think it is f(x)=1200x-2x²
takind the derivitive yeilds none of the others
so ya, you are right
Answer:
<em>78 eggs</em>
Step-by-step explanation:
13 × 6 = 78 eggs
Hope this helps! :)
Answer:
x = 18 y = 5
Step-by-step explanation:
x + 5 = 2x - 13
x - 2x = -13 - 5
-x = -18
x = 18
2y - 2 = 4y - 12
2y - 4y = -12 + 2
-2y = -10|:(-2)
y = 5
Answer:
McCoy should plant soybeans
Step-by-step explanation:
Thinking process:
Let the two crops be corn and soybeans as indicated.
The profit margin for corn will be $ 30 000. However, the loss will be:
$ 35 000 - $ 30 000 = $ 5 000
For the soybean, the profit margin will be $ 10 000.
The loss will be $ 5 000
The net balance will be given as: $ 5 000 - $ 10 000 = - $ 5 000. (This represents a gain)
Thus, soybean will be more profitable.
