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.
Did any of them feature older actors? ... Each culture has a certain set of expectations and assumptions about aging, all of ... In North America, the experience of being elderly has changed greatly over the past century.
Erosion and weathering wears down the rock
Humans affect the physical environment in numerous ways: overpopulation, contamination, burning fossil powers, and deforestation. Changes like these have triggered climate alter, soil erosion, poor air quality, and undrinkable water. These negative impacts can influence human behavior and can provoke mass migrations or battles over clean water.
Answer:
Ferrous (Fe²⁺) and magnesium cation (Mg²⁺).
Explanation:
The olivine mineral is a type of orthosilicate, which is generally yellow to yellow-green in color. It is the main component of the upper mantle of the Earth, which can be found in igneous and metamorphic rocks.
The olivine mineral exists in the form of Mg₂SiO₄, Fe₂SiO₄, or (Mg,Fe)₂SiO₄.
<u>This silicate consists of two divalent cations, ferrous (Fe²⁺) and magnesium cation (Mg²⁺).</u>
