Estimate the local maximum of...

Option A.

Step-by-step explanation:

The given equation is

     ...(1)

We need to find the local maximum.

Differentiate the given equation w.r.t. x.

      ...(2)

Now, equate y'=0 to find the extrem points.

Differentiate (2) w.r.t. x.

For ,

maximum

For ,

minimum

So, the given equation has local maximum at x=-1/3 and the maximum value is

The local maximum at (-0.33,9.48).

Hence, the correct option is A.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

the answer is (-4,-4)

hope this ! : d
