compound interest

composite interest. A method of calculating interest on money where the interest earned over a period of time is calculated on the basis of the original amount plus any interest earned in previous periods.

If £100 is invested at 10% interest per annum for three years, the amount will grow as follows:

Year 1
Year 2
Year 3

Amount
£100
£110
£121

Interest (10%)
£10
£11
£12.10

Value of money invested
£110
£121
£133.10

In general, if an amount of EP is invested at a compound interest rate of r, the amount after n years will be:

£P×(100+r/100)

computer
ordinateur m

Computer. An electronic device designed to process large amounts of coded information quickly.

Computer systems typically include three main components: input devices (such as a keyboard, paper tape, etc.), a central processor (central processor), and an output processor (such as a television monitor, printer, etc.).

Rapid advances in microelectronics technology have dramatically reduced the size and cost of computers while greatly increasing their processing power.

concave
concave

A concave curve or surface that is hollowed out toward a reference point.

A radio telescope dish is a concave surface toward the sky.

concentric circles
cercles mpl concentriques

Concentric circles. Two circles are concentric if they have the same center and different radii (radii).

concurrent

concourant

Convergent. Lines are convergent if they all meet at a single point. The three altitudes of a triangle are convergent.

cone
cône m

cone A cone is a solid bounded by a plane base (usually circular) and tapering at a certain point called the vertex. A right cone is a cone whose axis, or the line joining the center of symmetry at the base and the vertex, is perpendicular to the base.

The volume of a circular-based cone is: V=1/3πr²h

where r is the radius (radius) of the base and h is the height.

The curved surface area of ​​a right cone is:

Α=πrί
where a is the slant height.

congruent
congruent

Table. Congruent. Figures, plane or solid, are congruent if they have the same shape and size.

Some simple transformations, such as rotation, translation, and reflection, give congruent images of transformed objects.
