The most appropriate choice for similarity of triangles will be given by -
Speed of tip of the shadow of woman = 6 ft/s
What are similar triangles?
Two triangles are said to be similar, if the corrosponding angles of the triangles are same and the corrosponding sides of the triangles are in the same ratio.
Here,
The diagram has been attached here
Let the distance of woman from the pole be x ft and the distance of tip of the shadow to the pole be y ft.
Height of street light = 18 ft
Height of woman = 6ft
The two triangles are similar [As height of woman is parallel to the height of pole]
To find the speed, we have to differentiate both sides with respect to time 't'
Speed of tip of her shadow = 6 ft

Answer:
Step-by-step explanation:
The nth term for the geometric sequence is given by:
where,
is the first term
r is the common ratio
n is the number of terms.
As per the statement:
For the geometric sequence of and r=2
We have to find
for n = 5;
Substitute the given values we have;
⇒
Therefore, the value of is, 32
