Chain rule:
if
y=y(u) and u=u(x)
The dy/dx=(dv/du)(du/dx)
In our case
y=arcsin(u)
u=sin(x)
dy/du=1/√(1-u²) = 1/√(1-sin²x)
du/dx=cos x
dy/dx=cos x /√(1-sin²x)
Answer: dy/dx=cos x /√(1-sin²x)
The wall can be built in 22 days by 6 workers in first 6 days and 9 workers in the rest of time.
<h3>How to use inverse proportionality to determine building time of a wall</h3>
In this question we must use the definition of <em>inverse</em> proportionality, in which the number of workers (), no unit, is inversely proportional to the <em>building</em> time (), in days.
According to the statement, 6 workers spent 6 days building a wall and there are 24 days left for completion, but 3 more workers entered to reduce building time, which can be represented by the following expression:
In this scenario, the wall can be built in 22 days.

Answer:
the hypothesis is that the animal is a poodle. the conclusion is that since poodles are of the canine family, it would be a dog.
By the Pythagorean Theorem:
DE=√(100-64)
DE=√36
DE=6 ft
So our area is just a 4by4 square and a triangle with a height of 8 and a base of 6 so
A=(4*4)+(6*8)/2
A=16+24
A=40 ft^2
