Find the complement of the set given that
u = {x | x isin. gif i and −3 ≤ x ≤ 9}.

(enter your answers as a comma-separated list.)

{x | x isin. gif w and x < 7}

Step-by-step explanation:

The objective is to find the complement of the set given that

The set , written comma-separated equals

and the set is

                           .

We need to find all elements from the set that are not in the set .

Comparing the elements of this two sets yields

where denotes the complement of the set .

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
