The correct answer for this question is letter "<span>D. (x) / (sqrt (1+x^2))."

Make a triangle. yes a triangle. label "opposite" side x and adjacent side 1 since the tangent is x = x/1
use pythatoras to find the hypotenuse which will be
square root (1 + x^2)
then
<span>sin(ta<span>n<span>−1</span></span>(x)<span>) = x / (square root (1 + x^2))
</span></span>
that being opposite over hypotenuse
and by the same triangle
<span>cos(ta<span>n<span>−1</span></span>(x)) = </span>x / (square root (1 + x^2))

The standard equation of a circle is
,
where (a, b) is the center of the circle, and r is the radius.
So, if we write
in the above form, the center and the radius will be obvious to us.
Note that
is very close to
except for the 1.
Similarly, we notice that
is like
, without the 16.
So,
.
Answer:
What are the answers so i can see to figure it out
Answer:
c=26
Step-by-step explanation:
By using pythagoram thoerem
c^2=a^2+b^2
c^2=(10)^2+(24)^2
c^2=100+576
c^2=676
c=sqrt(676)
c=26
c=26
