At a particular time, objects and their shadows are proportionate.
Therefore, in figure,
--- (1)
where AB is the height of the lighthouse, BC, its shadow and FD is the height of Zara and DE is her shadow.
From the given information,
BC = 36 feet
FD = 4 feet and DE = 3 feet
(1) becomes
AB = 48
Hence, the height of the lighthouse is 48 feet.
Answer:
9
Step-by-step explanation:
Let the equation of a parabola be
= 4ax.
Then , focal length of the parabola is a.
As , (0,0) is the vertex and its focus is (a,0)
Thus, focal length comes out to be a.
Here,
a is given as 9 units .
Thus focal length of the parabola, d, equals to 9 units
The opposite side of the 11cm will also be 11cm and the 2 others will both be 8 cm.
The relative order of the metric prefixes is micro-, milli-, centi- and kilo-,
<h3>What are metric units?</h3>
Metric units are units used to measure quantities
The units are given as:
kilo-, micro-, centi-, and milli-
In metric units, the value of each prefix is:
Kilo = 1000
Micro = 0.0001
Centi = 100
Milli = 0.1
In order of arrangement, we have:
Micro = 0.0001
Milli = 0.1
Centi = 100
Kilo = 1000
Hence, the relative order of the metric prefixes is micro-, milli-, centi- and kilo-,
