Mathematics
1 answer:
Montano1993 [528]3 years ago
5 0

a) 0, 4, 8, 12, 16

explanation- simply add 4 to the previous number. 0+4= 4, 4+4= 8, 8+4= 12, etc etc.

b) 0, 8, 16, 24, 32

explanation- the same as letter a.

c) if you multiply the top number (the x value) by two, then you will get the bottom number (the y value)

explanation- 0+0= 0, 4+4= 8, 8+8= 16, 12+12= 24, and 16+16= 32

d) (0,0), (4,8), (8,16), (12,24), and (16,32)

explanation- the first number comes from the set in letter a (the x value) and the second number comes from the set in letter b (the y value).

e) -

explanation- find a spare piece of graph paper and put the points down. for example, (4,8) would be four places to the right on the horizontal line (the x-axis), and then down 8 places, still staying in the four postion. so four over, eight down. the vertical line is called the y-axis.

Hope this will help somewhat :)

Solve: 2cos(x)-square root 3=0 for 0 less than x less than 2 pi
Leona [35]

Answer:

The general solution of   cos x = cos(\frac{\pi }{6})   is  

                                                x = 2nπ±\frac{\pi }{6}

The general solution values  

                                 x = - \frac{\pi }{6}  and x = \frac{\pi }{6}

Step-by-step explanation:

Explanation:-

Given equation is  

                              2cosx-\sqrt{3} =0  for 0

                              2cosx =\sqrt{3}

Dividing '2' on both sides, we get

                             cos x =\frac{\sqrt{3} }{2}

                             cos x = cos(\frac{\pi }{6})

<em>General solution of cos θ = cos ∝ is θ = 2nπ±∝</em>

<em>Now The general solution of   </em>cos x = cos(\frac{\pi }{6})<em>   is  </em>

<em>                                                 x = 2nπ±</em>\frac{\pi }{6}<em></em>

put n=0

x = - \frac{\pi }{6}  and x = \frac{\pi }{6}

Put n=1  

x = 2\pi +\frac{\pi }{6} = \frac{13\pi }{6}

x = 2\pi -\frac{\pi }{6} = \frac{11\pi }{6}

put n=2

x = 4\pi +\frac{\pi }{6} = \frac{25\pi }{6}

x = 4\pi -\frac{\pi }{6} = \frac{23\pi }{6}

And so on

But given 0 < x< 2π

The general solution values  

                                 x = - \frac{\pi }{6}  and x = \frac{\pi }{6}
