Augustin has 20 different chess boards. If he played 3 games per day, each game played on a different board, how long would it t
Nutka1998 [239]

Answer:

514 days

Step-by-step explanation:

We use the formula (r+n-1)/r(n-1)

There are 1540 combinations. Then, we'll divide them by three because were not just finding the amount of combinations, but the time it'd take to play them all.

We get 513.333(cont.)

thats not really possible, so we're gonna go with 514 instead, rounding up. Normally we'd round down, because the number behind the decimal is below 5, but we really want to make sure we get every combination in there.

Hope this is helpful!

Verify this trig function. <br> tanysiny = secy-cosy ?
avanturin [10]
LHS\\ \\ =\tan { y } \sin { y } \\ \\ =\frac { \sin { y }  }{ \cos { y }  } \cdot \sin { y }

\\ \\ =\frac { \sin ^{ 2 }{ y }  }{ \cos { y }  } \\ \\ =\frac { 1-\cos ^{ 2 }{ y }  }{ \cos { y }  }

\\ \\ =\frac { 1 }{ \cos { y }  } -\frac { \cos ^{ 2 }{ y }  }{ \cos { y }  } \\ \\ =\sec { y } -\cos { y } \\ \\ =RHS

Find the 10th term <br><br> 3,15,75,375
vova2212 [387]

Answer:

5859375

Step-by-step explanation:

These are the terms of a geometric sequence with n th term

a_{n} = a_{1} r^{n-1}

where r is the common ratio and a_{1} the first term

here r = \frac{375}{75} = \frac{75}{15} = \frac{15}{3} = 5 and a_{1} = 3, hence

a_{10} = 3 × (5)^{9} = 5859375
