Aflagpole consists of a flexible, 2.57 m tall fiberglass pole planted in concrete. the bottom end of the flagpole is fixed in position, but the top end of the flagpole is free to move. what is the lowest frequency standing wave that can be formed on the flagpole if the wave propagation speed in the fiberglass is 2730 m/s?

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.

What is the slope of any line parallel to the line 8x+9y=3 in the standard (x,y) coordinate plane?
