If a function f(x) has an inverse f ⁻¹(x), then by definition

Differentiating both sides with respect to x yields

Now, if f(a) = b and b = f ⁻¹(a), then

What is m∠2 = m∠6 = 75<span>
What is m∠1 = 180 - 75 = 105</span>
Answer:
B) UY
Step-by-step explanation:
From the given figure, TUYX is one of the side of the rectangular prism and UVYZ is another side of the rectangular prism.
The both sides are intersecting perpendicular in one edge, that is the line segment UY.
You can see it on the figure.
Therefore, the intersecting line is UY.
The required number of the given question is 20.
Step-by-step explanation:
Given:
2
is 11% of a given number.
To find:
The given number
Let, the number be "x"
According to the problem,
2
= 11% of x
or, 2
= x ×
or,
= 
or, 11 ×5x = 100×11 [ by cross multiplication]
or, x = 20
