Question

0.6√x+1. при x=-0.75

Answer 1

$0.6 \sqrt{( - 0.75) + 1} = 0.6 \sqrt{0.25} = 0.6 \times 0.5 = 0.3$

Answer 2

To find the value of the expression 0.6√x + 1 when x = -0.75, we simply substitute the value of x into the expression and perform the calculation:

0.6√(-0.75) + 1

Now, let's calculate the square root of -0.75:

√(-0.75) ≈ √(0.75) * √(-1) ≈ √(0.75) * i ≈ 0.866i

(i is the imaginary unit, where i^2 = -1)

Now, plug this result back into the expression:

0.6 * 0.866i + 1

Multiplying 0.6 by 0.866i gives us:

0.6 * 0.866i = 0.5196i

So the expression becomes:

0.5196i + 1

Now, we add 1 to the imaginary part:

1 + 0.5196i = 1 + 0.5196i

The final result when x = -0.75 is approximately 1 + 0.5196i.
