Answer:Number of minutes of second Song = 5 1/4 minutes
Number of minutes of third Song =3 1/2 minutes
Step-by-step explanation:
Number of minutes of First Song = 3 1/2 minutes
Number of minutes of second Song = one 1/2 times as long as her first
= 1 1/2 X 3 1/2 minutes
3/2 X 7/2
21/4 = 5 1/4 minutes
Number of minutes of third Song = 2/3 times as long as her second song
2/ 3 x 5 1/4
= 2/3 x 21/4 =42/12
Dividing the numerator and denominator by 3 to reduce the fraction
42/ 12 / 3/3 = 14/4
14/4 = 3 2/4 = 3 1/2 minutes
Answer:
Graph C
Step-by-step explanation:
y = .7x
For a direct variation, we know that the line has to go through the origin (0,0)
This eliminates graphs b and d. We also know that the slope is .7
When x = 1, y = .7. This eliminates graph a, because when x=1 y =1. This leaves us graph c
Answer:
Explicit formula is an = 64(-3/4)^(n-1).
Step-by-step explanation:
Looks like a geometric sequence with a negative common ratio.
-48/64 = - 3/4
36 / -48 = -3/4
Now -27/36 = -3/4 so I think there's a typo in the question. Its -27 not -17.
The required formula is 64(-3/4)^(n-1) .
