Since beta is in the first quadrant, the final answer will be positive.

To find cos(beta) so we can use the half angle identity, we can substitute into the Pythagorean identity. Doing so gives us that

\sin( \beta )  =  \frac{ \sqrt{17} }{5}

So, this means that

\sin( \frac{ \beta }{2} )  =  \sqrt{ \frac{1 -  \frac{ \sqrt{17} }{2} }{2} }  =  \sqrt{ \frac{2 -  \sqrt{17} }{4} }  =  \frac{ \sqrt{2 -  \sqrt{17} } }{2}

(3x + 5)(x2 + 6x +11)<br> multiply
viva [34]

Answer:

3x³ + 23x² + 63x + 55

Step-by-step explanation:

Given

(3x + 5)(x² + 6x + 11)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(x² + 6x + 11) + 5(x² + 6x + 11) ← distribute both parenthesis

= 3x³ + 18x² + 33x + 5x² + 30x + 55 ← collect like terms

= 3x³ + 23x² + 63x + 55
