This statement means that the diver is going 30 meters under sea level. It is negative because sea level is 0, and anything below 0 is a negative.
Answer:
The answer would be 12
Step-by-step explanation
The answer would be 12 because the meter is calibrated to display 12 when it gets that 5 V signal internally and the range is set to AC. ... You don't say if you are measuring a battery or a power supply and if you are using a digital meter or a small analogue one.
![7+0.7+0.007+\cdots=7\left(1+\dfrac1{10}+\dfrac1{100}+\cdots\right)](https://tex.z-dn.net/?f=7%2B0.7%2B0.007%2B%5Ccdots%3D7%5Cleft%281%2B%5Cdfrac1%7B10%7D%2B%5Cdfrac1%7B100%7D%2B%5Ccdots%5Cright%29)
Let
![S_n](https://tex.z-dn.net/?f=S_n)
denote the
![n](https://tex.z-dn.net/?f=n)
th partial sum of the series, i.e.
![S_n=1+\dfrac1{10}+\dfrac1{100}+\cdots+\dfrac1{100^n}](https://tex.z-dn.net/?f=S_n%3D1%2B%5Cdfrac1%7B10%7D%2B%5Cdfrac1%7B100%7D%2B%5Ccdots%2B%5Cdfrac1%7B100%5En%7D)
Then
![\dfrac1{10}S_n=\dfrac1{10}+\dfrac1{100}+\dfrac1{1000}+\dfrac1{10^{n+1}}](https://tex.z-dn.net/?f=%5Cdfrac1%7B10%7DS_n%3D%5Cdfrac1%7B10%7D%2B%5Cdfrac1%7B100%7D%2B%5Cdfrac1%7B1000%7D%2B%5Cdfrac1%7B10%5E%7Bn%2B1%7D%7D)
and subtracting from
![S_n](https://tex.z-dn.net/?f=S_n)
we get
![S_n-\dfrac1{10}S_n=\dfrac9{10}S_n=1-\dfrac1{10^{n+1}}](https://tex.z-dn.net/?f=S_n-%5Cdfrac1%7B10%7DS_n%3D%5Cdfrac9%7B10%7DS_n%3D1-%5Cdfrac1%7B10%5E%7Bn%2B1%7D%7D)
![\implies S_n=\dfrac{10}9\left(1-\dfrac1{10^{n+1}}\right)](https://tex.z-dn.net/?f=%5Cimplies%20S_n%3D%5Cdfrac%7B10%7D9%5Cleft%281-%5Cdfrac1%7B10%5E%7Bn%2B1%7D%7D%5Cright%29)
As
![n\to\infty](https://tex.z-dn.net/?f=n%5Cto%5Cinfty)
, the exponential term vanishes, leaving us with
![\displaystyle\lim_{n\to\infty}S_n=\dfrac{10}9](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bn%5Cto%5Cinfty%7DS_n%3D%5Cdfrac%7B10%7D9)
and so
What about it? 7x+5 equals what
Answer:
£65.10
Step-by-step explanation:
42*8 = 336
10% = 33.6
14*15 = 210
10% = 21
5% = 10.5
31.5 +33.6 = £65.10
hope this is correct ^^
