Answer:
Step-by-step explanation:
Assume that the shadow of an object in this problem is proportional to the height of the object. One can form the following ratio to describe the objects in this problem,
As per the given problem, a (6) foot person casts a (1.7) foot shadow. Therefore, one can form the following ratio,
It is given that there is a lighthouse that has a shadow of (10.2) feet, one is asked to find its height. Use the parameter (x) to represent the unknown; since the ratios are related, one can form a proportion to solve for(x).

<h3>How to convert Celsius into Fahrenheit ?</h3>We are given that the temperature in degrees Celsius C can be converted to degrees Fahrenheit F
We know that the formula
If we are substituting c = -40
Then, we get
For every Celsius temperature, we get only one value of Fahrenheit.
The function is one-one because for every value of Celsius we get a unique value of Fahrenheit.
Hence, it is a function because every Celsius temperature is associated with only one Fahrenheit temperature.
Therefore, option B is true.
