Answer:
(0,0), (-1, 1), and (1,-1)
Step-by-step explanation:
If you were to plot all the points they would all end up being on the green line
I hope this helped?
Let's interpret this equation. If we have that a runner has 0 races under his belt, he completes the race in 38.1 min. We have that the slope is -1.2 min/race and the intercept at n=0 is 38.1 min. Hence, for every race, the duration of the run decreases by 1.2 min (or increases by -1.2 min).
Lets derive that. Suppose a runner that has run n races, runs once more.
The difference of times is:
(-1.2(n+1)+38.1)-(-1.2n+38.1)=-1.2(n+1)-(-1.2n)= -1.2n-1.2+1.2n=1.2 minutes.
Hence, the correct answer is the first.
To find perimeter you multiply.
164.042*82.021=13454.888888882 (8 repeating)
Answer:
see explanation
Step-by-step explanation:
Given the recursive formula
= 3
+ 2 and a₄ = 20
Then working in reverse
3a₃ + 2 = 20 ( subtract 2 from both sides )
3a₃ = 18 ( divide both sides by 3 )
a₃ = 6
3a₂ + 2 = 6 ( subtract 2 from both sides )
3a₂ = 4 ( divide both sides by 3 )
a₂ = 
3a₁ + 2 = ( subtract 2 from both sides )
3a₁ = - 
( divide both sides by 3 )
a₁ = - 
Hence
a₁ = -
a₂ =
a₃ = 6
3n - 24 (3 will go both into 3 and 24)
3(n - 8) - final answer
