Question

3k + 0,5(1-6k)-(7-6k) При k=0,05; при k= 0,05

Answer 1

Ответ:

- 6,56.

Объяснение:

3×0,05 + 0,5 (1 - 6×0,05 ) - ( 7 - 6×0,05 ) = 0,15 + 0,5 (1 - 0,3) - (7 - 0,3) = 0,2 × 0,7 - 6,7 = 0,14 - 6,7 = -6,56.

Answer 2

To evaluate the expression for the given values of k, let's substitute the values into the expression:

For k = 0.05: 3(0.05) + 0.5(1 - 6(0.05)) - (7 - 6(0.05))

Simplifying this expression step by step:

= 0.15 + 0.5(1 - 0.3) - (7 - 0.3) = 0.15 + 0.5(0.7) - 6.7 = 0.15 + 0.35 - 6.7 = 0.5 - 6.7 = -6.2

Therefore, when k = 0.05, the expression 3k + 0.5(1-6k) - (7-6k) evaluates to -6.2.
