Answer:
Solar panels
Explanation:
Solar panels produce electricity directly from the sunlight.
Solar panels use the photons. When the photons hit the panel they are absorbed by the panel’s semiconducting silicon material.
True costa rica has many conservation programs
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.
Hey There!
The Berlin Wall was built by East German troops and engineers on August 13, 1961. The wall was built to keep west Germans out, but it was built to keep eastern Germans in. Many eastern Germans were fleeing to the west because they felt that Western Germany better represented their ideals, political ideas, and culture. Hopefully this helped!
Cheers,
