2. 3x + 2y = 22<br> 5x – 2y = 42

hammer [34]

Step-by-step explanation:

3x+2y=22

5x-2y=42

by adding both equation

8x. =64

x=64/8=8

substituting x in the 1st equation

we get,

3*8+2y=22

24+2y=22

2y=22-24

y=-2/2=-1

therefore,

x=8

y=-1

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.
