Answer:
A) f(n) = 12 + 2(n-1)
Step-by-step explanation:
Arithmetic Sequence Formula:
a(n) = a(1) + (n-1)d
d = 2
a(1) = 12
a(n) = 12 + 2(n-1)
Answer:0
Step-by-step explanation:whatever its multiplied or divided is still 0
A = kdv^2 where A = amount oil d = distance and v = speed and k is a constant
so
30 = k*85*42^2
Now solve for k:-
k = 30 / (85*42^2) = 0.00020008
So when d = 26 and v = 54
Amount of oil A = 0.00020008 * 26*54^2
= 15.2 barrels
You are counting by 10s so the answer is 40,50,60,70,80
the complete sequence: 10,20,30,40,50,60,70,80,90,100
