Step 1

Given:

The sum of the first number and twice the second number is 108. help_outlineImage TranscriptioncloseFormula used: For a function fthat is twice differentiable on an open interval I, if f'(c)=0 for some c, then If f"(c)0the function fhas relative minima at c if f"(c)<0the function fhas relative maxima at c. If f"(c)=0the test fails fullscreen
Step 2

Calculation:

Let the two numbers be x and y.

From the given information, help_outlineImage Transcriptionclosex+2y 108...) Product xy. 2) Equation (1) can be written as, 2y 108-x (3) y 54 2 fullscreen
Step 3 help_outlineImage TranscriptioncloseSubstitute equation (3) in equation (1) - x Product x54 - 2 Product 54x 2 Both the numbers are positive, so that the feasible domain is 0
