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)

Laurie was scuba diving. Each time she dove 5 feet deeper, she would stop and clear her ears. After Laurie had checked her instr
Leona [35]

Complete question :

Answer:

(-5) * (20) * (3)

Step-by-step explanation:

Diving 5 feets deeper = descent = negative 5 Feets

Each time instrument is checked = (60/3) = depth of 20 feets

Number of times instrument is checked = 3

Hence, maximum depth :

Diving 5 feets deeper * Each time instrument is checked = depth of 20 feets * Number of times instrument is checked

(-5) * (20) * (3) = - 60

Line passes through the point (2,10) and has a y-intercept of 4. what is the equation of the line?
ZanzabumX [31]

Answer:

y = 3x + 4

Step-by-step explanation:

y = mx + b

b = y-intercept so:

b = 4

Since 4 is the y-intercept that means (0, 4).

To find slope:

m=(y2-y1)/(x2-x1)

m=(4 - 10)/(0 - 2)

m= (-6)/(-2)

m= 3

Slope-intercept:

y - y1 = m(x - x1)

y - 10 = 3(x - 2)

y - 10 = 3x - 6

y = 3x + 4

Find the value of (x+5y)' step by step
larisa86 [58]

Answer:

x²+10xy+25y²

Step-by-step explanation:

(x+5y)²=(x+5y)(x+5y)=x×x+5y×x+x×5y+5y×5y=x²+5xy+5xy+25y²=x²+10xy+25y²

But it can be much easier

(a+b)²=a²+2ab+b²
