Find approximate solution for the equation in the interval 0<_ x <_ pi. round to three decimal places. tanx=5 sin x

timofeeve [1]

Answer:

d. 0, 1.369

Step-by-step explanation:

Given:

The equation is: $\tan x =5\sin x................(0\leq x\leq \pi)$

Adding $-5\sin x$ on both sides, we get

$\tan x - 5\sin x=0$

Using the identity $\tan x=\frac{\sin x}{\cos x}$ , we get

$\frac{\sin x}{\cos x}-5\sin x=0$

Factoring out $\sin x$ , we get

$\sin x(\frac{1}{\cos x}-5)=0\\\\\therefore \sin x=0\ or\ \frac{1}{\cos x}-5=0\\\\x=\sin^{-1} (0)\ or\ \cos x=\frac{1}{5}\\\\x=0\ or\ x=\cos^{-1} (\frac{1}{5})\\\\x=0\ or\ x=1.3694\approx 1.369(\textrm{Round to 3 decimal places})$

Therefore, the solution of the given equation is either 0 or 1.369.

The correct choice is d.

If -13x-71=201 what is x

jenyasd209 [6]

Answer:

272/-13 or −20.923

Step-by-step explanation:

To solve this equation you need to isolate the variable.

First, add 71 to both sides

-13x-71+71=201+71

-13x=272

Then, divide both sides by -13

-13x/-13=272/-13

So, x=272/-13 or −20.923

75+20 1X -40+13 X +76 + 3X -20 = 720 solve for x

hoa [83]

Thanks.

Answer is 37x=720-20+20-75-76+40=609

x=609/37= 16.459 Assuming all the numbers are the same as we can see it in the equation.

Troyanec [42]

Answer:

$350\ decimeters$

Step-by-step explanation:

we know that

$100\ decimeters=1\ dekameter$

by proportion

$\frac{100}{1}=\frac{x}{3.5} \\ \\x=3.5*100\\ \\ x=350\ decimeters$
