Each piece will be 5 inches long because in each feet there is 12 inches so 12 times 5 equals 60 and 60 divided by 9 equals 6.66666666667 and that will be estimated to either each piece 5 inches or 6 inches long
Answer: 2 years
Step-by-step explanation:
The exponential growth function is given by :-
(i)
, where A = initial value , r = rate of growth and x= time period.
As per given ,
A= 242
r= 12% = 0.12
To find : t when y= 300.
Put all the values in (i)
Taking log on both sides , we get
hence, it will take 2 years.
Lets say the cost of her haircut is $x. This makes the cost of her perm 2x (twice as much). If lunch ($5), the perm ($2x) and the haircut ($x) cost, in total, $50, we can say:
50 = 5 + 2x + x
Combine like terms:
50 = 5 + 3x
Subtract 5 from both sides to isolate 3x
50 - 5 = 3x
45 = 3x
Divide all by 3 to isolate x
x = 45/3
x = 15
So the haircut is $15 and the perm is $30 (2*$15).
Hello,
2/10,-6/100,18/1000,-54/10000,162/100000;...
a(n+1)/a(n)=-3/10
a(0)=2/10*1
a(n)=2/10* (-3/10)^(n-1)
