Точка рухається по закону s(t) = 1 + 2t2 (м). Знайдіть швидкість руху точки в момент часу t = 1 с.(З поясненням будьласка)

Ответ:

Так як швидкість це похідна від шляху, то

s(t) = 1 + 2t^2

V(t)=s'(t) = 4t

в момент часу t = 1 с :

V(1)=s'(1) = 4*1=4 м/с

колонки: Active Voice и Passive Voice
1.
Different airlines have their
own computerized cargo systems. The problem is that while all these are fine
systems, few of them can communicate with each other.

2.
The new Cargo On LINE
(CAROLINE) system links all external and internal cargo-shipping participants
into one paperless flow of information.

3.
Airlines want to be linked
with the large network of agents, forwarders, shippers, banks, customs offices
and other segments of the cargo community.

4.
The key phrase to
computerized cargo systems is Electronic Data Interchange (EDI). This is what
eliminates the endless process of telephone calls, facsimile and telex
messages, and waybill shipments.

5.
SAS used EDI to create an
electronic switchboard, enabling its computers to communicate with computers
used by the cargo industry throughout Scandinavia. This is the Trade Vision.

6.
Trade Vision communicates in Electronic Data
Interchange for Administration, Commerce and Transportation (EDI FACT), one of
two major computer languages and the one used by the United Nations. The other,
used by IATA, is IMP, or Interchange Message Procedures. Cargo operators use
CARGO IMP.

7.
Trade Vision will be used as
the core of the new system, which forms a community of cargo computer programs.
Essentially, it will serve two functions. The first is networking, which allows
users to communicate. Like a well-trained telephone operator, this system takes
incoming calls and sends them out to the proper office.

8.
The second is the data bank,
or information library, which provides users with rates, routings, customs
requirements, hazardous-cargo
requirements, tracking and the myriad information needed to ship cargo
throughout the world. Anyone using the system will be able to sit at a single
computer terminal and send and/or receive all necessary data for the shipment
of a piece of cargo.

9.
The communication-networking
function also “translates” the incoming message into the appropriate language
for transmittal.

10.
Overall benefits provided by
the system include better service and higher efficiency; approximately 10 %
reduction in staff, reduced operative and maintenance costs.
