Question

( 0,8 - 6, 5 ) • ( 7,2 - 13, 2 ) а) -43,8б) 43, 8в) 4, 38​

Answer 1

$(0,8-6,5)\cdot (7,2-13,2)=-5,7\cdot (-6)=34,2$

Answer 2

Ответ: подходящего ответа нет. Ответ34,2

Объяснение:

7,2-13,2=-6. 6*(6,5-0,8)=34,2

Проверьте знак 0,8-6,5.

Если знак не минус, а плюс, то

7,3*6=43,8 Ответ Б

Answer 3

To calculate the dot product of the given vectors, we multiply their corresponding components and sum them up. Let's perform the calculation:

(0, 8 - 6, 5) • (7, 2 - 13, 2)

= (0 * 7) + (8 * 2) - (6 * 13) - (5 * 2)

= 0 + 16 - 78 - 10

= -72

Therefore, the dot product of the given vectors is -72.

None of the answer options provided (a) -43,8, b) 43,8, c) 4,38) matches the result obtained.
