60 minutes make an hour therfore 60 muliplyied by 5 is 300 then 30 divided by 300=0.1 minutes
The answer is 3b. hope it helps
The complete question is
<span>-2 2/3, -5 1/3, -10 2/3, -21 1/3, -42 2/3, ... Which formula can be used to describe the sequence?
a. f(x + 1) = –2f(x)
b. f(x + 1) = f(x)
c. f(x + 1) = -f(x)
d. f(x + 1) = 2f(x)
case a) </span>f(x + 1) = –2f(x)
for f(x)=-2 2/3
f(x+1)=-2*[-2 2/3]=5 1/3
5 1/3 is not -5 1/3
therefore
this is not the formula
case b) f(x + 1) = f(x)
for f(x)=-2 2/3
f(x+1)=-2 2/3
-2 2/3 is not -5 1/3
therefore
this is not the formula
case c) f(x + 1) = -f(x)
for f(x)=-2 2/3
f(x+1)=2 2/3
2 2/3 is not -5 1/3
therefore
this is not the formula
case d) f(x + 1) =2f(x)
for f(x)=-2 2/3
f(x+1)=2*[-2 2/3]=-5 1/3
for f(x)=-5 1/3
f(x+1)=2*[-5 1/3]=-10 2/3
for f(x)=-10 2/3
f(x+1)=2*[-10 2/3]=-21 1/3
for f(x)=-21 1/3
f(x+1)=2*[-21 1/3]=-42 2/3
therefore
the answer is the option
d. f(x + 1) = 2f(x)
For the first one each side would be 2.05. Because 2.05 x4 = 8.2. I hope this helps.
