You would need 24 machines

Can I get the answers for number 14 plz?
nataly862011 [7]
A.
-1: 
2(2)^{-1}  \\ 2( \frac{1}{2}) \\  \frac{2}{2}  \\ 1
(-1,1)

0:
2(2)^{0} \\ 2(1) \\ 2
(0, 2)

1:
2(2)^{1}  \\ 2(2) \\ 4
(1, 4)

2:
2(2)^{2} \\ 2(4) \\ 8
(2, 8)

3:
2(2) ^{3}  \\ 2(8) \\ 16
(3,16)

b.
To graph the equation, simply go through the points (-2, 0.5), (-1, 1), (0,2), (1,4), (2,8), and (3,16). Make sure you never go below 0 on the x-axis, because there's an asymptote there.

Hope this helps!

Given that cosΘ=8/17 and sinΘ=-15/17 what is the value of tanΘ?
Marta_Voda [28]
<span>tanΘ is given by the following equation:

</span>\frac{sin\theta}{cos\theta}
<span>
Plug in your known values into the formula:

</span>\frac{\frac{8}{17}}{\frac{-15}{17}} =  \frac{8}{17} \div \frac{-15}{17} = -\frac{8}{15}

tanΘ is equal to -8/15.
