A company has 2725 employees. Each employee is to be given an ID number that consists of one letter followed by 1 digits. How many different ID numbers are possible

There are 260 different ID numbers are possible.

Step-by-step explanation:

Given: Each employee is to be given an ID number that consists 1 letter followed by 1 digit .

Number of choices for each letter = 26 [English alphabet consists 26 letters]

Number of choices for each digit = 10

By Fundamental counting principle,

The number of different ID numbers possible = (Number of choices for each letter) x (Number of choices for each digit)

=26 x 10= 260

Hence, there are 260 different ID numbers are possible.

(x - 3)² + (y + 4)² = 49

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + *y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (3, - 4) and r = 7 , then

(x - 3)² + (y - (- 4) )² = 7² , that is

(x - 3)² + (y + 4)² = 49 ← equation of circle
