Use strong induction to show that every positive integer n can be written as a sum of distinct powers of two, that is, as a sum of a subset of the integers 2^0 = 1.2^1 = 2. 2^2 =4. and so on. (hint: for the inductive step, separately con- sider the case where k + 1 is even and where it is odd. when it is even, note that (k + 1)/2 is an integer.]

step-by-step explanation:

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

sorry not knowing about that
