МАТЕМАТИКА!!! ПРОШУ!!! ПОМОГИТЕ!! ПОЖАЛУЙСТА!!! ЭТО ОЧЕНЬ ОЧЕНЬ СРОЧНО!!!



Укажите уравнения плоскостей, которые перпендикулярны плоскости 5х-2у+4z=0

1) 2x-2y+3z-4=0

2) 15x-6y+12z-4=0

3) 5x-2y+4z-2=0

4) 5x-2y+6z-4=0

Ответ:

Для того чтобы найти плоскости, параллельные данной плоскости 5x-2y+4z=0, нужно использовать то же самое уравнение, но изменить правую часть уравнения.

Таким образом, плоскости, параллельные данной, будут иметь следующий вид:

5x-2y+4z=k, где k - произвольная константа.

15x-6y+12z=k, где k - произвольная константа.

5x-2y+4z=k, где k - произвольная константа.

5x-2y+6z=k, где k - произвольная константа.

Таким образом, уравнения плоскостей будут иметь вид:

5x-2y+4z=k

15x-6y+12z=k

5x-2y+4z=k

5x-2y+6z=k

где k - произвольная константа.
