Give an example of a function. give the relation as a set of ordered pairs. use a test such as mapping or the verical line test to show if your set of ordered pairs is a function. an example of a function could be: distance traveled and time, or the cost of a turkey and its weight. you can list your relation as a set of ordered pairs, or as a table. in either case, you must prove the relation is a function using one of the two tools given to you in the prior lessons.

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
