Suppose customers in a hardware store are willing to buy N(p) boxes of nails at p dollars per box, as given by the following fun

Viktor [21]

Answer:

(a) - 25 boxes per dollar

(b) - 20 boxes per dollar

Step-by-step explanation:

Given that,

Consumer's willing to buy boxes of nails at p dollars per box:

N(p) = 80 - 5p^{2}

(a) Change in price from $2 to $3.

N(2) = 80 - 5(2)^{2}

= 80 - 20

= 60

N(3) = 80 - 5(3)^{2}

= 80 - 45

= 35

Therefore, the average rate of change of demand is

= [N(3) - N(2)] ÷ (3 - 2)

= 35 - 60

= - 25 boxes per dollar.

(b) N(p) = 80 - 5p^{2}

Now, differentiating the above function with respect to p,

N'(p) = -10p

Therefore, the instantaneous rate of change of demand when the price is $2 is calculated as follows:

N'(p) = -10p

N'(2) = -10 × 2

= -20 boxes per dollar

Need help to Find the apothem.

EleoNora [17]

The apothem of a polygon, in this case a, can be found using the formula

Apothem=circumradius*cos(pi/sides)

Note in this problem, its a hexagon which makes the circumradius = to the side length since a regular hexagon can be split into 6 equilateral triangles.

a=47*cos(pi/6)=40.7 (approximation)

Hope it helped!
