14. Each semester at college, a student must pay tuition costs plus a student service fee. To take
five courses in a semester costs $3270, and
to take four courses costs $2640.
a) Find the cost per course.
b) Find the student service fee.
c) Find the domain and range.

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

the answer is 1/4
