Answer:

72,000

Step-by-step explanation:

1) We must find the <u>difference in population</u> within the 5 year period from 2005 to 2010.

This is the equation I've used to find the answer

(45,000 - 18,000) / 5 = 5,400

2) Add the starting amount by 10x the difference in population (5,400)

<em>`10 years from 2005 is 2015.</em>

<em />

18,000 + (10 * 5,400) = 72,000

Katarina [22]

Complete Question

The length of the guy wire supporting a cell tower is 120 m. The guy wire is anchored to the ground at a distance of 80 m from the base of the tower to the nearest hundredth of a meter how tall is the tower?

Answer:

89.44m

Step-by-step explanation:

We solve this question using the Pythagoras Theorem

This is given as:

Hypotenuse² = Opposite ² + Adjacent ²

Hypotenuse = Length of the guy wire = 120m

Adjacent = Distance from the base of the tower = 80m

Opposite = Height of the building = x

Hence:

120² = x² + 80²

Collect like terms

x² = 120² - 80²

x = √120² - 80²

x = √(8000)

x = 89.4427191 m

Approximately the height of the tower is = 89.44m
