Question

(у — 4)² + 2(у – 9) при у =- 0,1.​

Answer 1

Пошаговое объяснение:

4,1²-0,2-9=16,81-0,2-0,9=15,71

Answer 2

To evaluate the expression (у - 4)² + 2(у - 9) when у = -0.1, we substitute the value of у into the given expression:

(у - 4)² + 2(у - 9)

Substituting у = -0.1:

((-0.1) - 4)² + 2((-0.1) - 9)

Simplifying inside the parentheses:

(-0.1 - 4)² + 2(-0.1 - 9)

(-4.1)² + 2(-9.1)

Calculating the squared term:

(-4.1)² = 16.81

Now evaluating the remaining term:

2(-9.1) = -18.2

Now we substitute the results back into the expression:

16.81 + (-18.2)

Finally, summing up the values:

16.81 - 18.2 = -1.39

Therefore, when у = -0.1, the expression (у - 4)² + 2(у - 9) evaluates to -1.39.
