Using the arrangements formula, it is found that there are 40,320 ways for these swimmers to finish.

<h3>What is the arrangements formula?</h3>

The number of possible arrangements of n elements is given by the factorial of n, that is:

A_n = n!

In this problem, there are n = 8 swimmers, hence they can finish arranged in 8! ways, that is:

A_8 = 8! = 40320

Given that sine= 21/29, what is the value of cos 0, for 0° &lt;0&lt;90°? A -square root of 20/29 B -20/29 C 20/29 D square root
Stolb23 [73]

Answer:

Step-by-step explanation:

sin=y/r

cos=x/r

sin=21/29

cos=x/29

x^2+y^2=r^2

x^2+21^2=29^2

x^2+441=841

x=sqrt(841-441)

x=20

cos=20/29

                       

  Only              |

   sin +             |     All Positive

---------------------|-------------------

           only      |    Only cos +

            tan +    |
