Question

√6-2c при c=2,5 c=-5 c=-15 c=-37,5​

Answer 1

Решение:

√6-2c

✓ если c = 2,5, то √(6 -2•2,5) = √(6-5) = √1 = 1;

✓если c = -5, то √(6 -2•(-5)) = √16 = 4;

✓если c = -15, то √(6 -2•(-15)) = √36 = 6;

✓если c = -37,5​, то √(6 -2•(-37,5)) = √(6+75) = √81 = 9.

Answer 2

To calculate the value of the expression √6 - 2c for different values of c, you simply need to substitute the given values of c into the expression and perform the calculations. Let's do it step by step:

1. c = 2.5: √6 - 2 * 2.5 √6 - 5 ≈ -1.3588 (rounded to four decimal places)

2. c = -5: √6 - 2 * (-5) √6 + 10 ≈ 10.4495 (rounded to four decimal places)

3. c = -15: √6 - 2 * (-15) √6 + 30 ≈ 30.4495 (rounded to four decimal places)

4. c = -37.5: √6 - 2 * (-37.5) √6 + 75 ≈ 75.4495 (rounded to four decimal places)

So, for the given values of c, the expression √6 - 2c evaluates to:

c = 2.5: ≈ -1.3588 c = -5: ≈ 10.4495 c = -15: ≈ 30.4495 c = -37.5: ≈ 75.4495
