Answer:

$P(A)= 0.95 \: and \: P(A∩B)=0.37. \\ Find \: P(B∣A) \\ P(B∣A) = \frac{P(A∩B)}{P(A)} \\ = \frac{0.37}{0.95} \\ \therefore \: P(B∣A) = 0.389$

Find the expansions of sin⁡5θ and cos⁡5θ in terms of sin⁡θ and cos⁡θ.

qwelly [4]

$\bf \textit{quad-angle identities}\\\\\\

cos(4\theta)=8cos^4(\theta)-8cos^2(\theta)+1
\\\\\\
sin(4\theta)=
\begin{cases}
8sin(\theta)cos^3(\theta)-4sin(\theta)cos(\theta)\\\\
4sin(\theta)cos(\theta)-8sin^3(\theta)cos(\theta)
\end{cases}\\\\
-----------------------------\\\\
$

$\bf sin(5\theta)\iff sin(4\theta + \theta)
\\\\\\
sin(4\theta)cos(\theta)+cos(4\theta)sin(\theta)
\\\\\\\
[4sin(\theta)cos(\theta)-8sin^3(\theta)cos(\theta)]cos(\theta)\\\\ + [8cos^4(\theta)-8cos^2(\theta)+1]sin(\theta)$

$\bf -----------------------------\\\\
cos(5\theta)\iff cos(4\theta + \theta)
\\\\\\
cos(4\theta)cos(\theta)-sin(4\theta)sin(\theta)\\\\\\\
[8cos^4(\theta)-8cos^2(\theta)+1]cos(\theta)\\\\
-
[4sin(\theta)cos(\theta)-8sin^3(\theta)cos(\theta)]sin(\theta)$

Which is the greatest common factor of the expression below?<br> 32a²b2 + 36a²c2 – 16ab3

yKpoI14uk [10]

Answer:

Step-by-step explanation:

32a²b² = 2 * 2*2*2*2 * a² * b²

36a²c² = 2 * 2 * 3 * 3 * a² * c²

16ab³ = 2 * 2 * 2* 2 * a * b³

Greatest common factor = 2*2*a = 4a

32a²b² + 36a²c² - 16ab³ = 4a*(8ab² + 9ac² - 4b³)
