H(x)=0.000371(x
Zina [86]

The height of the towers above the ground is 152 meters.

<h3>Procedure - Determination of the height of the towers in the Golden Gate Bridge</h3>

The expanded form of the function is h(x) = 0.000371\cdot x^{2}-0.47488\cdot x + 152, a

quick though reasonable approach consists in evaluating the function for x = 0, that is, the <em>horizontal</em> distance with respect to the <em>left</em> tower to determine the height of the each tower of the Golden Gate Bridge.

If we know that x = 0\,m, then the height of the towers is:

h(0) = 152\,m

The height of the towers above the ground is 152 meters. \blacksquare

<h3>Remark</h3>

The statement is poorly formatted. Correct form is presented below:

<em>The Golden Gate Bridge is a suspension bridge that consists of two cables hung from two towers of equal height that are 1280 meters apart. The function </em>h(x) = 0.000371\cdot (x^{2}-1280\cdot x) + 152<em> models the height of each cable above the ground in meters, as it relates to the cable horizontal distance from the left tower in meters. What is the height of the towers in meters?</em>

homo rudolfensis is so morphologically similar to ________ that they may be regarded as the same species.
LenKa [72]

In terms of morphology, Homo rudolfensis and <u>Homo habilis </u>can be considered to be one species.

An extinct species of early Pleistocene humans known as Homo habilis, or "handy man," lived in East and South Africa between 2.31 million and 1.65 million years ago. When H. habilis was first described as a species in 1964, there was a lot of debate about it.

Many scientists suggested that it be grouped with Australopithecus africanus, the only other early hominin that was known at the time, but as time went on and more pertinent discoveries were made, Homo habilis gained more recognition. By the 1980s, it was believed that Homo habilis was a direct progenitor of modern humans, developing into Homo erectus along the way.
