Answer:
Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume. Ecologists estimate the size and density of populations using quadrats and the mark-recapture method.
Explanation:
Answer:
We know that the Great Plains are older than the Rocky Mountains because the Great Plains are more eroded than the Rocky Mountains.
Answer:
In a zone of divergence on the surface, lower atmosphere, would have dry weather.
Explanation:
Air flowing down and diverging at the surface is a high-pressure system. The air is moving to the warmer surface and will not condensate or form clouds. This will lead to a lack of precipitation. In hot desert regions, there is little precipitation and the temperatures hot. In the Arctic and Antarctic, there are areas of divergent surface winds as cold air is rushing down to lower latitudes to heat up. This means that is it also dry but cold.
Answer:
(4, 3)
Explanation:
<u>Short answer</u>: when the coordinates are on horizontal and vertical lines, as these are, each coordinate value is used twice. Already, x=0 is used twice, as is y=0, so the missing coordinate is x=4, y=3.
The fourth vertex is (4, 3).
_____
<u>Longer answer</u>: The midpoints of the diagonals are the same point, so for rectangle ABCD, we have ...
(A+C)/2 = (B+D)/2
Solving for D, we find ...
D = A +C -B
In clockwise order, the points given are ...
A = (4, 0), B = (0, 0), C = (0, 3)
so we have ...
D = (4, 0) +(0, 3) -(0, 0) = (4+0-0, 0+3-0)
D = (4, 3) . . . . the coordinates of the fourth vertex.
