Answer:
x=1.666667,−1.666667
Step-by-step explanation:
9x^2−25=0
<u><em>Step 1: Add 25 to both sides.</em></u>
9x^2−25+25=0+25
9x^2=25
<em><u>Step 2: Divide both sides by 9.</u></em>
9x^2/9=259
x^2=25/9
<em><u>Step 3: Take square root.</u></em>
x=±25/9
x=1.666667,−1.666667
Answer:
Step-by-step explanation:
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The concentration of the pollutants starts at Co=5 mg/lt. We also know the pollutant reduces its concentration by 10% each hour. This gives us a value of r = 10% / 100 = 0.1
Substituting into the general equation:
Operating:
