Answer:
Disadvantages of mathematicsl models are given.
Step-by-step explanation:
Disadvances of mathematicsl models are the model is a limited or bounded cases which taken from huge number of situations by ignoring many unknown facts of the real problem and does not include all important parameters or trivial parameters for accuricy of the result of system dynamics which gives a better result of the problem. The model may also only work in certain major state variables and parameters which may effect largly on the whole system.
D because of the distribution property
Answer:
23 and 25
Step-by-step explanation:
x and x+2
x+3(x+2)=98
x+3x+6=98
4x=92
x=23
x+2=25
∴
=2796202.5
Step-by-step explanation:
First term(a) = 
common ratio(r) =
=4
n= 12
=2796202.5
∴ =2796202.5
Multiply by 2 which will get you a diameter and then multiply it by pi which is 3.14.
