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

Answer:

$cos\theta$ = $\sqrt{\frac{85}{121}}$

$tan\theta$ = $\frac{6}{\sqrt{85}}$

Step-by-step explanation:

given, $sin\theta$ = $\frac{6}{11}$

since, $sin^2\theta$ + $cos^2\theta$ =1

$cos^2\theta$ =1- $sin^2theta$

$cos^2\theta[/tax]=1-[tex]\frac{36}{121}$

= $\frac{121-36}{121}$

= $\frac{85}{121}$

$cos\theta$ = $\sqrt{\frac{85}{121}}$ answer

$tan\theta$ = $\frac{sin\theta}{cos\theta}$

$tan\theta$ = $\frac{6}{\sqrt{85}}$ answer
