Based on the weight and the model that is given, it should be noted that W(t) in radians will be W(t) = 0.9cos(2πt/366) + 8.2.
<h3>
How to calculate the radian.</h3>
From the information, W(t) = a cos(bt) + d. Firstly, calculate the phase shift, b. At t= 0, the dog is at maximum weight, so the cosine function is also at a maximum. The cosine function is not shifted, so b = 1.
Then calculate d. The dog's average weight is 8.2 kg, so the mid-line d = 8.2. W(t) = a cos t + 8.2. Then calculate a, the dog's maximum weight is 9.1 kg. The deviation from the average is 9.1 kg - 8.2 kg = 0.9 kg. W(t) = 0.9cost + 8.2
Lastly, calculate t. The period p = 2π/b = 2π/1 = 2π. The conversion factor is 1 da =2π/365 rad. Therefore, the function with t in radians is W(t) = 0.9cos(2πt/365) + 8.2.

Answer:
54
Step-by-step explanation: you add 35 and 11 together then subtract 100 by the number you got to get the anwser
Answer:
Explanation:
The expression that must be rewritten as a fully simplified fraction is:
You must, first, convert as a fraction.
The line over the decimal 4 means that the digit 4 repeats indefinetly.
To find the fraction that represents this number you follow this procedure:
Now, you can mutiply both fractions:
Answer:
1. -10x^2-x+6-10x 2-x+6 = -10x^2 - 22x + 12
2. 10x^2-510x 2-5 = 10x^2 - 1020x - 5
