Answer:

Step-by-step explanation:

a maximum or minimum occurs where the derivative equals zero

f(x) = -2x² + 14x - 10

f'(x) = -4x + 14

0 = -4x + 14

4x = 14

x = 3.5

f(3.5) = -2(3.5)² + 14(3.5) - 10 = 14.5

Sunny_sXe [5.5K]

Answer:

Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal  .

Step-by-step explanation:

Given as :

The cost of each calendar = $ 9

The number of calendar sold to the family = 16

The number of calendar sold to the neighborhood = 14

So, Total number of calendar sold by Celia = The number of calendar sold to the family + The number of calendar sold to the neighborhood

i.e Total number of calendar sold by Celia = 16 + 14 = 30

∵ The cost of each calendar = $ 9

∴ The cost of 30 calendar = $ 9 × 30 = $ 270

Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal  .  Answer
