Answer:
0.0189
Step-by-step explanation:
We solve for this using Newton's Law of cooling.
The formula for Newton's Law of cooling =
T −Ts = (To−Ts)e^-kt
T = Temperature after cooling
To = Initial temperature
Ts = Room temperature
k = constant
t = time = 2 mins
(200 - 70) = (205 - 70)e^-2k
130 = 135e^-2t
e^-2k= 130/135
k = In(130/135)/-2
k = 0.018870164
Approximately to 4 decimal places = 0.0189
Therefore, the value of k = 0.0189

The -th term in the series is 6 multiplied by the -th power of 5/6:
and so on.
Consider the -th partial sum,
Multiplying both sides by 5/6 gives
and substracting this from gives
As , it's clear that the sum converges to 36.
The geometric series in the question is convergent with a common ratio of 5/6. Using the formula for the sum of an infinite geometric series, the sum of the series is found to be 36.
In mathematics, specifically in series, determining whether a geometric series is convergent or divergent is centered around the common ratio value. In terms of this particular series: 6 + 5 + 25/6 + 125/36 + ..., the common ratio is 5/6. Given this common ratio, it's clear that it falls between -1 and 1. Hence, this geometric series is convergent.
Once we establish it is a convergent series, we can calculate its sum using the formula for the sum of an infinite geometric series: S = a / (1 - r), where 'a' is the first term and 'r' is the common ratio. Inserting the respective values a = 6 and r = 5/6, we get: S = 6 / (1 - 5/6) = 36. Hence, the sum of this infinite geometric series is 36.

Answer:
(32, 31) (33,30) (34, 29) (35, 28) (36,27) (37, 26)
Step-by-step explanation:
The pairs of whole numbers that add to 63 and have a difference less than 10 are (27, 36), (28, 35), (29, 34), (30, 33), and (31, 32).
This problem is based in the domain of basic algebra. Essentially, you are being asked to find pairs of whole numbers that, added together, equal 63, with the condition that the difference between these two numbers is less than 10.
Starting from the number 32 (as any larger number plus any number greater than 0 would exceed 63), you can begin to list pairs, subtracting one number from the total of 63 while simultaneously adding that same amount to the other half of the pair. This will ensure that the sum always equals 63.
Here are the pairs satisfying the given conditions: (27, 36), (28, 35), (29, 34), (30, 33), (31, 32). For these pairs, the difference between the two numbers in each pair is less than 10.

Hey there!
x + 8 = -5
SUBTRACT 8 to BOTH SIDES
x + 8 - 8 = -5 - 8
CANCEL out: 8 - 8 because it give you 0
KEEP: -5 - 8 because it help solve for the x-value
NEW EQUATION: x = -5 - 8
SIMPLIFY IT!
x = -13
Therefore, your answer is: x =-13
Good luck on your assignment and enjoy your day!
