Step-by-step explanation:
A. this is a geometric sequence.
according to y-coordinates =>
3, 6, 12, 24
have a T1 = 3 and ratio = 6/3 = 2
B. the formula = Tn = r. T(n-1)
T5 = 2. T4
= 2. 24 = 48 minutes
C. the formula : Tn = T1 . r^(n-1)
T9 = 3. 2^(9-1)
= 3. 2^8
= 3. 256
= 768 munutes
Hey there!
The first thing we can do is find the number of third in 4.
We can do this by multiplying 4 by 3 since there are 3 thirds in a whole.
4 x 3 = 12
So, 4 = 12/3
If she studies for 2/3 an hour each night, then we can divide 12 by 2 to figure out how many 2/3 go into 12/3.
12 ÷ 2 = 6
So, she studied for 6 days.
Hope this helps!
