d) The drag coefficient in aircraft industry affected by some parameters which are thespeed of plane (v), the plane length (L), the air density (p), the air dynamic viscosity(u), and speed of sound (a). By using dimensional analysis, identify two non-dimensionnumbers in which the drag coefficient is a function of them and explain how these twowill effect on drag coefficient.

The reynols number is Re Re is ration of inertia force and viscous force. Then the formula is,

By using dimensional analysis, identify two non-dimension numbers in which the drag coefficient is a function of them and explain how these two will effect on drag coefficient.

please describe by computer and mention clearly thank you. what is meant by the gradient of a function at a particular point. Does it measure the same characteristic for all functions? Why or why not?
Examine each function for relative extrema. What does relative extrema mean? (A) f(x,y)=−x^2−2y^2 (B) g(x,y)=(x−1)^2 +y^2 (C) h(x,y)= x^3/3 −xy
Variable name Variable label Person Participant number Age Age (years) Height Height (cm) preweight Weight before the diet (kg) Diet Diet weight10weeks Weight after 10 weeks (kg) From the given table determine whether these variables are eg, (nominal, ordinal, continuous)
method of converting nonparametric data to parametric data
Estimate the input value(s) where the function has a relative extreme point. Identify each relative extreme as a maximum or minimum, and indicate whether the derivative of the function at that point is zero or does not exist maximum or minimum? input value derivative Select (smallest value) Select ' -Select Select --Select --Select (largest value) y 2 0.5 3 15 2 2.5
