Ivanshal [37]

Answer:

let \: the \: angle \: be \:  \alpha  \\  \tan( \alpha )  =  \frac{p}{b}  \\  \tan(16.8) =   \frac{2.7}{x}  \\ x =  \frac{2.7}{0.30 }  \\ x = 9 \\ now \: by \: using \: pythagoras \: theorem \:  \\ h =  \sqrt{p {}^{2} }  + b {}^{2}  \\ h =  \sqrt{ {2.7}^{2} }  +  {9 }^{2}  \\ h = 9.396

Use set notation to write the members of the following set, or state that the set has no members. Odd numbers between 2 and 82 t
adell [148]

Let the set of all Odd multiples of 9 between 2 and 82 be denoted by D, then, using set-builder notation,

D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}

The odd multiples of 9, m, in the range 2\le m \le 82 form the set

\{9,27,45,63,81\}

Each member of the set is a term of the arithmetic progression

U_n=18n+9

where the values of n range from 0 to 4, or 0\le n\le 4

Putting these facts together, we get the result

D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}
