Answer:

15:- 10cm

16:- 169cm

Step-by-step explanation:

Original length of steel stock was 2.1m = 210cm

A piece of 8.6 dm(86cm) & 81cm and 330mm(33cm)

{coversion:1m=100cm,1dm=10cm,1mm=0.1cm]

remaining piece length equal to: 210cm-(86cm+81cm+33cm)

=(210- 200)cm=10cm

• 42 stall in 70.98m span(7098cm)

• 1stall is in (7098/42)cm span

i.e, 169 cm

Solve using algebraic equation: <br> 5sin2x=3cosx<br><br> (No exponents)
DaniilM [7]
5\sin2x=3\cos x\iff10\sin x\cos x=3\cos x

by the double angle identity for sine. Move everything to one side and factor out the cosine term.

10\sin x\cos x=3\cos x\iff10\sin x\cos x-3\cos x=\cos x(10\sin x-3)=0

Now the zero product property tells us that there are two cases where this is true,

\begin{cases}\cos x=0\\10\sin x-3=0\end{cases}

In the first equation, cosine becomes zero whenever its argument is an odd integer multiple of \dfrac\pi2, so x=\dfrac{(2n+1)\pi}2 where n[/tex ]is any integer.\\Meanwhile,\\[tex]10\sin x-3=0\implies\sin x=\dfrac3{10}

which occurs twice in the interval [0,2\pi) for x=\arcsin\dfrac3{10} and x=\pi-\arcsin\dfrac3{10}. More generally, if you think of x as a point on the unit circle, this occurs whenever x also completes a full revolution about the origin. This means for any integer n, the general solution in this case would be x=\arcsin\dfrac3{10}+2n\pi and x=\pi-\arcsin\dfrac3{10}+2n\pi.

What is the 44th decimal digit in the decimal representation of 1/11?
Alexus [3.1K]
The decimal representation of  1/11  is  0.090909...
The pair of digits '09' repeat forever.

If you start counting the digits after the decimal point,
the odd ones are all zero, and the even ones are all  9 .

So the 44th digit after the decimal point is  9 .
