Answer:
The number of elephant ears that must be sold to maximize profit is 400.
Step-by-step explanation:
Given that,
The profit that a vendor makes per day is given by
P(x)= - 0.004x² +3.2 x -200
where x is number of elephant ears.
P(x)= - 0.004x² +3.2 x -200
Differentiating with respect to x
P'(x)= - 0.008x+3.2
Again differentiating with respect to x
P''(x) = -0.008
For maximum or minimum P'(x)=0
- 0.008x+3.2=0
⇒0.008x=3.2
⇒ x = 400
Since at x=400, P''(x)<0, the profit is maximize.
P(400) = -0.004×400²+3.2×400-200
=440
The number of elephant ears that must be sold to maximize profit is 400.
Answer:
Part 1) The product of 3 and 2y-4x=8 is
Part 2) The original equation in slope intercept form is
Part 3) The new equation in slope intercept form is
Step-by-step explanation:
we have
step 1
Find out the product of 3 and 2y-4x=8
Multiply both sides by 3
Apply distributive property both sides
step 2
Find out the original equation in slope intercept form
The equation of the line in slope intercept form is
we have
Solve for y
That means ----> Isolate the variable y
Adds 4x both sides
Divide by 2 both sides
Simplify
step 3
Find out the new equation in slope intercept form
The equation of the line in slope intercept form is
we have
Solve for y
That means ----> Isolate the variable y
Adds 12x both sides
Divide by 6 both sides
Simplify
