a proportional relationship?
1 answer:
Answer:
C) The third table. K= 5

Step-by-step explanation:
1) Below there are the missing data:
A proportional relationship through a constant k. It is obtained when we divide:

2)In this case, when we divide the temperature (T) by the time (h).

3)So, examining the table below we are searching for a ratio k common to all measures (temperatures over hour).

20 000 * 0.08(8%)= 1600
1600 * 20(years) = 32 000
Therefore you would have $32 000 after 20 years
Answer:
(2, -8)
Step-by-step explanation:
(x, y)=(-3, -1)
(x1+x2)/2=-3,
(y2+y2)/2=-1,
-------------------
(x1+x2)/2=-3
(y1+y2)/2=-1
---------------------
x1-8=-6
x1=2
----------
y1+6=-2
y1=-8
(2, -8)
