Which of the following is NOT equal to sin pi/3
Yanka [14]

Answer:

D)  sin(\frac{4\pi }{3} ) = sin(\pi +\frac{\pi }{3} ) = -sin\frac{\pi }{3}

Step-by-step explanation:

A)

sin(\frac{2\pi }{3} ) = sin ( \pi - \frac{\pi }{3} ) = sin\frac{\pi }{3}

B)

cos (\frac{\pi }{6} ) = cos ( \frac{\pi }{2} - \frac{\pi }{3} ) = sin(\frac{\pi }{3})

C)

cos (\frac{11\pi }{6} ) = cos ( \frac{3\pi }{2} + \frac{\pi }{3} ) = sin(\frac{\pi }{3})

D)

 sin(\frac{4\pi }{3} ) = sin(\pi +\frac{\pi }{3} ) = -sin\frac{\pi }{3}

-7(z-6)= -70 i need help
vichka [17]

Answer:

z=16

Step-by-step explanation:

-7(z-6)= -70

combine -7 with the bracket

-7z + 42 = -70

      -42        -42

-7z = - 112

divide both sides by -7

-7z/-7 = -112/-7

z = 16

check

-7(z-6)= -70

-7(16-6)= -70

combine

-112+42= -70

  -42         -42

-112 = -112

now <span>hundredth part:</span>
300 * 0.01 = 3,
0.02 = 2 * 0.01 = 6

90 + 6  = 96
