Explanation

• In the simplex method, the slack, surplus, and artificial variables are restricted to be non-negative.
• This means that their values must be greater than or equal to zero.

Explanation

• The correct answer is: 6^C2

This is because:

• 5^C2 = 10
• 5^C1 = 5
• 10 + 5 = 15

And:

• 6^C2 = 15
• So, 5^C2 + 5^C1 = 6^C2.

Explanation

Explanation

• The trigonometric identity sin²x + cos²x = 1 can be rearranged to isolate sin²x: sin²x = 1 - cos²x
• So, sin²2θ = 1 - cos²2θ

Explanation

• The function f is defined as f(a) = 1, f(b) = 1, and f(c) = 1.
• This means that every element in the domain (A) is mapped to the same element (1) in the codomain (B).
• This is a characteristic of a constant function, which is a function that always returns the same output value regardless of the input.

Explanation

The formula =5 + 2 * 3 follows the order of operations (PEMDAS):

• Multiply 2 and 3: 2 * 3 = 6
• Add 5 to the result: 5 + 6 = 11
