More and more businesses and homeowners are installing solar panels on their roofs to draw energy from the sun's rays. According
to the U.S. Department of Energy, the solar cell kilowatt-hour use in the United States (in millions) is projected to be S(t) = 0.73t2 + 15.8t +2.7 (0 < t < 8) in year t, with t = 0 corresponding to 2000. What was the number of projected solar cell kilowatt-hours used in the United States for 2001? For 2002?
The equation would be d - 19 = 73. So the zoologist would take the number of deer recorded and subtract it from 19 (since it said 19 fewer deer) and the answer would be 73 (because that is how many deer were recorded a year later. I hope this helps!
