A stage consists of a painted backdrop with some wooden flat object in front, to create depth. One of the flats is a lamppost with a similarity ratio of 1/2 to an actual lamp post. To give the illusion of distance, the backdrop includes a small painted lamp post that has a similarity ratio of 1/10 to the flat lamp post.

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

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
