11. a triangle has vertices at p(7,7), q(-3, -5), and r(5, -3).
a a) determine the coordinates of the midpoints of the three sides
of apqr.
b) calculate the slopes of the midsegments of apqr.
c) calculate the slopes of the three sides of apqr.
d) compare your answers for parts b) and c). what do you notice?

the answer is 15% decrease

i will with my problems and all the other things that need to   be on by the way

step-by-step explanation:

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.
