Question

-2 × √c²/1,44 + 2|c| , при c < 0

Answer 1

-2 × √c²/1,44 + 2|c| = -2*(|с|/1,2) +|c| = -2|c| + |c| -2,4 = -|c|-2,4

Answer 2

To simplify the given expression, let's break it down step-by-step:

1. Start with the expression: -2 × √(c²)/1.44 + 2|c|.

2. Simplify the square root of c²: √(c²) = |c|, since the square root of a squared value gives the absolute value.

3. Replace √(c²) with |c|: -2 × |c|/1.44 + 2|c|.

4. Now, we have two terms with |c|: -2|c|/1.44 + 2|c|.

5. Factor out the common term |c|: |c| × (-2/1.44 + 2).

6. Evaluate the expression inside the parentheses: -2/1.44 + 2 ≈ -0.3889 + 2 ≈ 1.6111.

7. Final expression: |c| × 1.6111.

So, the simplified expression for the given function when c < 0 is: 1.6111|c|.
