Since the argument of the sine function is x without any scaling factor, the period is 2π, the 1st selection.
All sides of as quaer are equal
4 sides to a square
therefor perimiter=4 times 1 side
if 1 side=4' then 4 sides=4 times 4'=16'
answer is 16'
Answer:
Step-by-step explanation:
This is an arithmetic sequence with first term -46 and common difference 1.
So,
Newton's law of cooling is
k (t₁ - t₂) = -ln (T₁ - T∞ / T₂ - T<span>∞)
Use the two data points in the given to find k.
t = 0, T = 154
t = 10, T = 133
Solution:
k(0 - 10) = - ln (154 - 71/ 133 - 71)
-10k = -0.291716
k = 0.02917 or 0.0292
So now find t when T = 100
0.2917 * ( 0 - t) = -ln (154 - 71 / 100 -71)
- 0.02917t = - 1.0515
t = 36. 05 minutes
to the nearest minute t = 36</span>
