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 -
so it will be
maximum value = -240 -
maximum value = 98
so here maximum profit attained at
x = 
x = 
x = 13
maximum profit = 13
2 * (2a + b) + 8 = 4a + 2b + 8
------------------------------------------
A. =
B. =
C. ≠ 4* (a + b + 2) = 4a + 4b + 8
D. =
Answer:Backward
Step-by-step explanation:
If the car next to Megan is being Pulled Forward and Megan is seeing only the pulled car then her car appears to be moving backward.
This can be said by using the concept of relative velocity which states that the speed of the body with respect to the other is considered to be at rest.
Here Megan's car appears to move backward with respect to the car next to her due to the existence of relative velocity.
