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).

Answer:
The given series converges and 
Step-by-step explanation:
Given is 108, -18, 3,...
It is an alternate series. An alternate series is convergent if:
1. The series is decreasing.
2. If the last term (n-th term) of series converges to 0.
<u>Since each next term is less than its preceding term, so it is decreasing.</u>
First term, a = 108
Second term = -18
Common ratio, r = -18/108 = -1/6
General term, aₙ = a*rⁿ = 108*(-1/6)ⁿ
<u>When n increases to infinity, the exponent term will decreases to zero, and last term (n-th term) will converge to 0 as well.</u>
Hence, the given series converges.
Now limit will be: 

Hence, 
Answer: x = 25%
Step-by-step explanation: 45% + 30% = 75%
75% + 25% = 100%
C , i dont know if it’s right but it’s the only table with the same number on the bottom . and same number in general
