While its reinforced concrete and steel construction physically allows the St. Petersburg Pier to stand, from a distance the up-side down, triangular shaped pyramid suggests an un-stable form. This is a good example of :a. modern, Neo-Egyptian Engineering. b. the use of "Pendentives". c. Perceptual Structure. d. Tri-Partite structure

answer: This is a good example of the use of "Pendentives".

Pendentives is a construction device which placed some sort of elliptical dome over a rectangular room.

This type of structure makes the building able to hold large sized ornaments on the ceilings and providing a lot of room for people at the same time, which is really ideal if its used as museum or Churches

Explanation:

the anasazi indians were real pioneers and created roads and irrigation systems for watering their crops. they were also great architects and the cliff dwellings are one of their biggest achievements.

explanation:

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
