Answer:
Think of it as the perimeter of the circle
Good question I’m not sure what it is but I’m sure you can look on google
Answer:
the answer is x because its small
Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)
Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))
Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
The equivalent expression to 7^13/7^7 would be 7^6.
<h3>What are equivalent expressions?</h3>
Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
We have given an expression as 7^13/7^7
The equivalent expression;

Hence, The equivalent expression to 7^13/7^7 would be 7^6.
