Answer:
Step-by-step explanation:
Left = 2000 * (1/2)^x
Try it.
x = 1
Left = 2000 * (1/2)^1
left = 2000 * 1/2
left = 1000
x = 3
left = 2000 (1/2)^3
left = 2000 (1/8)
left = 250
x = 4
left = 2000 * (1/16)
left = 125
from her on the function does not work accurately. You have to modify the algorithm.
Answer:
Step-by-step explanation:
The y intercept is (0,5)
The slope is found from choosing 2 points on the line. My choice is (4,13) and (0,5)
x2 = 4
x1 = 0
y2 = 13
y1 = 5
slope = (y2 - y1)/(x2 - x1)
slope = (13 - 5)/(4 - 0) = 8/2 = 4
If I'm right answers A and D are both wrong. We don't know exactly what the 5 represents. I would say it is the beginning number of songs she knows when she starts graphing. In any event, B is not the answer.
That leaves C.
y = 2x + 5
x = 20
y = 2*20 + 5
y = 45
(20,45) is on the line

Answer:
1 1/5 hours walking to 1 hour jogging
Step-by-step explanation:
You can multiply by 3 to eliminate the fraction, then reduce in the usual way.
4 ÷ (3 1/3)
= 12 ÷ 10 . . . . . . . multiply both numbers by 3
= 1 2/10 = 1 1/5 . . . . do the division by 10
