3 0

Answer:

M ∪ D= { 2, 3, 4 , 6 , 7}

M ∩  D= { 2, 4 , 6}

Step-by-step explanation:

UNION OF SETS : The union of two sets P and Q  is the set of elements which belong in A or in B or in both.

Here,  M =  {2,3,4,6,7}   D  =   {2,4,6}

⇒ M ∪ D= { 2, 3, 4 , 6 , 7}

INTERSECTION OF SETS :  The intersection  of two sets P and Q  is the set of elements which belong in A and B both.

Here,  M =  {2,3,4,6,7}   D  =   {2,4,6}

         ⇒ M ∩  D= { 2, 4 , 6}

valentina_108 [34]

Answer:

N(x) = 40 - 2x

P(x) = -2x² + 52 x - 240

maximum profit = 13

Step-by-step explanation:

given data

feeder cost = $6

average sell = 20 per week

price = $10 each

solution

we consider here price per feeder = x

and profit per feeder  id here formula   = x - 6

so that here

total profit will be

P (x)  = ( x - 6 ) Nx

here N(x) is number of feeders sold at price =  x

so formula for N (x)  is here

N(x) = 20 - 2 ( x - 10 )    

N(x) = 40 - 2x

so that

P(x) = (x-6) ( 40 - 2x)

P(x) = -2x² + 52 x - 240

since here

a = -2

b = 52

c = -240

a < 0

so quadratic function have maximum value of c - \frac{b^2}{4a}

so it will be

maximum value = -240 - \frac{52^2}{4(-2)}

maximum value = 98

so here maximum profit attained at

x = \frac{-b}{2a}

x = \frac{-52}{2(-2)}

x = 13

maximum profit = 13
