Answer:
n=N-1
Step-by-step explanation:
You can start by imagining this scenario on a small scale, say 5 squares.
Assuming it starts on the first square, the grasshopper can cover the full 5 squares in 2 ways; either it can jump one square at a time, or it can jump all the way to the end and then backtrack. If it jumps one square at a time, it will take 4 hops to cover all 5 squares. If it jumps two squares at a time and then backtracks, it will take 2 jumps to cover the full 5 squares and then 2 to cover the 2 it missed, which is also 4. It will always be one less than the total amount of squares, since it begins on the first square and must touch the rest exactly once. Therefore, the smallest amount n is N-1. Hope this helps!

Answer:
3,264
Step-by-step explanation:
You have to use the straight line in the middle of the triangle as the height, the 12 below it as length, and the 34 on the side as width. And I must say, this prism is quite WIDE
Answer: the slope is 1
Step-by-step explanation:
Slope = Rise over Run. Rise= y run= x
For this problem the rise is the difference between 3 and 1 and the run is the difference between 0 and -2. The difference between 3 and 1 is 2 and the difference between 0 and -2 is also too. Which makes it 2/2 which simplifies to 1.
Answer:
DB = 8
Step-by-step explanation:
Δ ADB and Δ BDC are similar so ratios of corresponding sides are equal, that is
= 
, substitute values
= 
= ( cross- multiply )
DB² = 64 ( take the square root of both sides )
DB = 
= 8
