Answer:
<h2>The missing value is 3, and the coordinates are (3,3).</h2>Step-by-step explanation:
The complete question is
Complete the missing value in the solution to the equation. (3, ? )
By given, we know that , because coordinates are written like
.
Then, we replace the given coordinate to find .
Therefore, the missing value is 3, and the coordinates are (3,3).
Answer:
Step-by-step explanation:
x is the number of years. y is the population after x years.
Each year, the population decreases by 22%, since 100% - 22% = 78%, and 78% = 0.78, each year, the population is 0.78 of the previous year's population.
year zero: y = 300
year 1: y = 300 * 0.78 = 300 * (0.78)^1
year 2: y = (300 * 0.78) * 0.78 = 300 * (0.78)^2
year 3: y = ((300 * 0.78) * 0.78) * 0.78 = 300 * (0.78)^3
year x: y = 300(0.78)^x
