the ratio of boys to girls in a class is 4:5.whar fraction of the class are boys?what fraction of the class are girls

4/9 are boys and 5/9 are girls

Step-by-step explanation:

4:5 equals to 4+5 which is 9, that is your denominator, then you take the 4 and the 5 and sort them into boys and girls. Once you've done this, you should have 4/9 boys and 5/9.

answer: procent 54 wynosi 33,33%

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.
