9y+7 + 7y-19 = 180
Y =12 degrees
If they are decreasing at 3% , net = 100% - 3% = 97%
Reduction rate = 97% = 0.97
After 1st year = 1200*0.97
After 2nd year = 1200*(0.97)*(0.97) = 1200*(0.97)²
After 3rd year = 1200*(0.97)*(0.97)*(0.97) = 1200*(0.97)³
After x years, = 1200(0.97)ˣ
Therefore, function f(x) = <span>1200(0.97)ˣ</span>
In writing numerical numbers, you should identify the three-letter groupings. The first three-letter grouping would be the hundreds, followed by thousands, by millions, by billions, by trillions, and so on and so forth. In this case, we highest would be billions. So, in word form, that would be: three billion, one hundred fifty two million, three hundred eight thousand and seven hundred twenty six.
