Ответ:

Пошаговое объяснение:

d = (3 * 2 + 3 - 4; 3 * 3 + 0 - (-3); 3 * (-5) + 1 - 2) = (5; 12; -16)

|d| = √(5² + 12² + 16²) = √425 = 5√17

Read the text «BOOKWORM’S LOVE OF READING» and decide whether the following

sentences are true.He is a bookworm and has no other hobbies.

Chun-To reads one or two books a week.

His favourite books are famous classics. To read more he exchanged books with his classmates. He borrowed books from school. BOOKWORM'S LOVE OF READING
WINS HIM TOP AWARD Thirteen-year-old Chun-To started with one or two books а week but in the past nine months he has read 137 books — enough to win the Education Department's Extensive English Reading Scheme award. Не became the top student from 19 schools participating in the Scheme run by the Institute of Language in Education. The Wong Shiu Chi Secondary School pupil suggested that he probably was а kind of bookworm and that he had few other hobbies, though he did once represent his primary school in а table tennis contest. But most evenings he spent reading to try to improve his English. “Every evening after my homework I set aside one to two hours reading the story books. And when I had finished the ones I borrowed from school I exchanged them with my schoolmates, sо I can read more,” he said. Chun-To said his favourite books were science fiction, detective and horror stories but most of the titles he read for the competition were famous classics. “At first I had tо read twice some of the books I found difficult,” he admitted. The school will not allow students to borrow books over the summer holidays but Chun-To said he hoped tо continue his reading next term. But as for his future career, he was still undecided. “I want to work in an office rather than labouring and I want to be able to use my mind, but it's too early for me to decide what I might do,” he said.
