At a certain vineyard it is found that each grape vine produces about 10 lb of grapes in a season when about 700 vines are planted per acre. for each additional vine that is planted, the production of each vine decreases by about 1 percent. so the number of pounds of grapes produced per acre is modeled by a(n) = (700 + n)(10 − 0.01n) where n is the number of additional vines planted. find the number of vines that should be planted to maximize grape production.

Number of vines that should be planted are 150.

Step-by-step explanation:

The number of pounds of pounds of grapes produced per acre is represented by the expression

Where n = additional vines planted

To maximize the production of grapes we will find the derivative of A(n) and equate it to zero.

For

3 - 0.02n = 0

0.02n = 3

n =

n = 150

To check whether the maximum value of the function is at n = 150, we will find the second derivative A(n).

Which shows A"(n) < 0

Therefore, A(n) has the maximum value at n = 150.

Therefore, number of vines that should be planted are 150.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.

it would open into a square depending on the type of envelope i’m not sure about the second part
