Ответ:

г)20​.

Пошаговое объяснение:

f(x)=3x^2-4x+9

f'(x)=(3x^2-4x+9)' = 3•2х - 4 + 0 = 6х-4;

f'(4)=6•4 - 4 = 24 - 4 = 20.

5 вопросов по тексту на англ языке.

When we think of Paris, Rome. Madrid, Lisbon and other European capitals, we think of them as "cities'. When we think of the whole of modern London, the capital city of England and the United Kingdom, that great area covering several hundred square kilometres, we do not think of it as 'a city. not even as a city and its suburbs. Modem London is not one city that has steadily become larger through the centuries; it is a number of cities. towns, and villages that have, during the past centuries, grown together to make one vast urban area.

London is situated upon both banks of the River Thames, it is the largest city in Britain and one of the largest in the world. Its population is about 7 million people.

London dominates the life of Britain. It is the chief port of the country and the most important commercial, manufacturing and cultural centre. There is little heavy industry in London, but there is a wide range of light industry in Greater London.
.

The City extends over an area of about 2.6 square kilometres in the heart of London. About half a million people work in the City but only less than 6000 live here. It is the financial centre of the UK with many banks, offices and Stock Exchange. But the City is also a market for goods of almost every kind, from all parts of the world.

The West End can be called the centre of Tendon. Here are the historical palaces as well as the famous parks. Hyde Park with its Speaker's Corner is also here. Among other parks are Kensington Gardens, St.James's Park. In the West End is Buckingham Palace. Which is the Queen's residence, and the Palace of Westminster which is the seat of Parliament.
