Tim is reading a book. on monday he reads 3 pages. on each day after that, he reads triple the number of pages as the previous day. how many pages does ire read on thursday.

The number pages read on Thursday is 81 pages.

Step-by-step explanation:

Hint - This is problem of Geometric Series.

On Monday Tim read 3 pages. He reads triple the number of pages as the previous day.

So on Tuesday he will read = pages, so the series is

As Thursday is the 4th days.

So we have to find the 4th term.

We know that the nth term in a GP is,

where,

a = 1st term = 3,

r = common ratio = 3

n = 4

Putting the values,

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.

any of them that add up to 180 degrees.
