Answer:

10 units

Step-by-step explanation:

\boxed{distance =   \sqrt{(x2 - x1)^{2}  + (y2 - y1)^{2} }}

Using the distance formula above,

distance between the 2 points

=  \sqrt{[0 - ( -  8)]^{2} + (7 - 1)^{2}  }  \\  =  \sqrt{(0 + 8)^{2} + 6^{2}  }  \\  =  \sqrt{ {8}^{2}  + 36}  \\  =  \sqrt{64 + 36}  \\  =  \sqrt{100}  \\  = 10 \: units

Amber is starting a garden. She plants 2 flowers the first month. The next month, she plans three times more flowers (6 flowers)
Artist 52 [7]
This is a geometric progression problem. We can the general formula that can tell us how many flowers would be planted each month.
Let's write the terms that we know and see if we can find the pattern:

\begin{tabular}{lll}
Month & Number of flowers planted & Different form            \\
1     & 2                         & 2\cdot3^0 \\
2     & 6                         & 2\cdot3^1 \\
3     & 18                        & 2\cdot3^2 \\
4     & 54                        & 2\cdot3^3
\end{tabular}
\end{table}
The patern here is obvious. Let's write it down:
N=2\cdot3^{n-1}
This formula gives us a number of flowers planted in the n-th month.

Why can't the input value be negative?
ddd [48]

If you are working with time or days, you can't put in a negative value because if you are doing an experiment, you can't go back in time to do that experiment to gather data. (Time for the most part considered to be an input value so that's why I used it as an example.)
