Prove graphically and algebraically that a clockwise rotation of 270° about the origin has an equivalent counterclockwise rotation. in your final answer, name the equivalent counterclockwise rotation and show all of your work. on your graph, label the following: 1. parallelogram park and the coordinates of all four of its vertices 2. parallelogram p'a'r'k' and the coordinates of all four of its vertices 3. center of rotation and its coordinate 4. the invisible circle of rotation, its radius and the length of the radius 5. use arrows to show the clockwise movement of the parallelogram

c

step-by-step explanation:

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
