<u>Answer:</u>
The height of the tower nearby the pole is 102 m.
<u>Solution:</u>
Given,
Height of the pole = 3.5 m
Length of the shadow of the pole = 1.47 m
Length of the shadow of the tower nearby = 42.75 m
Let us assume the height of the tower as x
On solving for x we get,
On rounding off to the nearest meter we get,
x=102 m
The height of the tower is 102 meter.

Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this firm use the method of completing the square
Factor out - 1 from each term
y = - (x² - 9x + 12)
To complete the square
add/subtract (half the coefficient of the x- term )² to x² - 9x
y = - (x² + 2( - )x +
-
+ 12 )
= - ( (x - )² -
)
y = - (x - )² +
← in vertex form
