Answer:
Step-by-step explanation:
Step-by-step explanation:
By taking ( x = 18°)
<u>L.H.S</u>
cos(3x)=sin(2x)
cos(3x) = cos( 3X18°)= cos (54°)
= cos[ 90° - (2x18°)] ∵[ 90°- (2x18°) = 54°]
= ∴ sin ( 2x18°)
As (x = 18°)
= sin (2x) = R.H.S
Answer:

Step-by-step explanation:
Initial number of sick wolves = W(0) = 10
At time t, no. of sick wolves = W(t)
Given that disease is spreading at a rate proportional to the product of the time elapsed and the square root of the number of sick wolves:

Mathematical model of above case is:
