This is the simplest form.
Using exponentials inverse function (logarithms )
Or common base method which is not always easily applicable
ln600 = ln2100 + xln0.5
x = ln(600/2100) / ln0.5 = 1.81
Answer:
Kindly check explanation
Step-by-step explanation:
The initial elevation is 20m
According to the question :
If it changes to 16m, then the final elevation of the bird is 16 m.
However, in some texts, the question goes thus;
A bird starts at 20m and changes 16m? The bird's final elevation is?
In this case, the initial height = 20m
Change in height = 16 m (positive means ascension)
Hence,
initial height + change in height
20 m + 16 m
= 36m
Answer:
The answer is 0
Step-by-step explanation:
Answer:
option: D is the correct answer.
( D. 64=0.025 x+7 )
Step-by-step explanation:
We are given step as:

?
57=0.025x
-----------(2)
2280= x.
We are asked to find the missing step.
Clearly after equation (1)
They have squared the equation both side to obtain:

and then they took the constant term to the left hand side to obtain equation (2).

Hence, the correct option is:
Option: D
D. 64=0.025 x+7
