Rita finished her chemistry assignment in 7/8 hours. then she completed her math assignment in 1/4 hours. how much more time did rita spend on her chemistry assignment

Rita spend of hour more on her chemistry assignment.

Step-by-step explanation:

Fraction of an hour Rita spent on chemistry assignment =

Fraction of an hour Rita spent on math assignment =

∴ Fraction of  hour Rita spent more on her chemistry assignment than math assignment

⇒  

To subtract fractions we take LCD for 4 and 8. Since 8 is the least common multiple for 4 and 8 so, we take LCD= 8

To make the denominators same we need to multiply numerator and denominator of second fraction with 2.

⇒

⇒

After making the denominators common, we simply subtract numerators.

⇒

⇒

Therefore, Rita spend of hour more on her chemistry assignment.

a. -0.3 > -0.33

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.
