the second is a reflection across the x axis
the third is a reflection across the y axis
this just reverse the points, i'm not sure if it's anything
Step-by-step explanation:
Let the nth term be given by the expression an²+bn+c.
We can write A: -7=a+b+c B: -6=4a+2b+c C: -3=9a+3b+c
D: B-A: 1=3a+b
E: C-B: 3=5a+b
E-Dm 2=2a, a=1, b=1-3=-2, c=-7-1+2=-6.
So the expression for the nth term is n²-2n-6.
Put n=4: 16-8-6=2 which fits the sequence.
Put n=5: 25-10-6=9 which also fits the sequence.
So the nth term is
Answer:
18.8 minuites
Step-by-step explanation:
20% of 5 is 1 so the second time is 6 and 30% of 6 is 1.8 so it will be
5+6+7.8=18.8
