A sculpture is in the shape of a hyperboloid. The structure is 4 feet wide at the base, 2 feet wide at its narrowest point which is 13 feet off the ground and 32 feet tall. What is the width of the structure five feet above the ground?

step-by-step explanation:

1/800 is the right answer

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

so, converting firstly the mixed fractions to improper fractions and then "adding".
