If the given solutions y⃗ =−, y⃗ =−11]. form a fundamental set (i. e., linearly independent set) of solutions for the initial value problem y⃗ ′=−2−−21−−1+−−1−−2]y⃗ , y⃗ (3)=[927], > 0, impose the given initial condition and find the unique solution to the initial value problem for > 0. if the given solutions do not form a fundamental set, enter none in all of the answer blanks. y(t) = [t^2 - 2t 2t]+ [t - 1 1]

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

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
