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

Can you help with this question step by step please
A regression was done for 20 cities with the latitude (Latitude), a measurement of the distance of a location on the Earth from the equator in degrees and the average January temperatures (Temp) as the dependent variable measure in. The regression equation is a) The value of the slope is [Select ] [Select] TEMP=48.4 -0.31 x LATITUDE b) The predicted average January temperatures for the 20 cities for a latitude of 45 degrees is [Select] ✓. If in fact the [Select] average January temperature for a latitude of 45 degrees is 40° F , the residual is [Select] which is a(n) [Select] which means c) The coefficient of determination is R²: 66.2%. This value means [Select] The correlation r, is which means [Select] d) The y-intercept is [Select] the problem interprets to [Select] make sense in the context of the problem? [Select] Formulas: r = ±√R² Residual actual y - predicted y 0.7<|rl≤1 very strong 0.5
