Answer:
- 5x² + 3x + 27
Step-by-step explanation:
To find the polynomial subtract 5x² - 3x - 9 from 18, that is
18 - (5x² - 3x - 9) ← distribute parenthesis by - 1
= 18 - 5x² + 3x + 9
= - 5x² + 3x + 27 ← required polynomial
#1 = -2 over -3. #2= y - (3.8)= 2.6(x-5.1)
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>
Don’t have a calculator but it’s 6.75 times 3
