The following table shows the percentage of the U. S. Discretionary Budget allocated to education in 2003, 2005, and 2009 (t = 0 represents 2000).

Year t 3 5 9
Percentage P(t) 6.8 7 6.2
Compute and interpret the average rate of change of P(t) over the period 2003−2005 (that is, [3, 5]), and over the period [5, 9]. Be sure to state the units of measurement. HINT [See Example 1.]

(a) over the period 2003−2005 (that is, [3, 5])

The average rate of change was ---Select--- % % per day % per month % per year , which means that U. S. education expenditure ---Select--- increased decreased at an average rate of ---Select--- % % per day % per month % per year during 2003−2005.

(b) over the period [5, 9]

The average rate of change was ---Select--- % % per day % per month % per year , which means that U. S. education expenditure ---Select--- increased decreased at an average rate of ---Select--- % % per day % per month % per year during 2005−2009.

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

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
