Answer:
Height of the building = 50.8 ft
Step-by-step explanation:
A person and a building are casting the shadows at the same time of the day.
Triangles formed by the person and his shadow and the building and its shadow will be similar.
Therefore, corresponding sides of the similar triangles will be proportional.
x =
x = 50.75
x ≈ 50.8 ft
Answer:
Step-by-step explanation:
It is given that the graph corresponds to a natural logarithmic function.
That means, the function has a natural log (Log with base
) of some terms of x.
It is given that asymptote of given curve is at . i.e. when we put value
, the function will have a value
.
We know that natural log of 0 is not defined.
So, we can say the following:
is not defined at
i.e. is the point where
a = 3
Hence, the function becomes:
Also, given that the graph crosses x axis at x = -2
When we put x = -2 in the function:
And y axis at 1.
Put x = 0, we should get y = 1
So, the function is:
