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
Answer:
± 5
Step-by-step explanation:
2x/-5 = -10/x
2x^2 = 50
x^2 = 25
x = ± 5
Answer:

Step-by-step explanation:
<u>Solution 1:</u>
Notice the
coordinate of both points are equal, meaning both points are on a vertical line. The distance between two points on a vertical line is the absolute difference of their y-coordinates. The absolute difference between
and
is
.
<u>Solution 2:</u>
The distance between two points
and
is:

Plugging in given values, we have:
.
Answer:
28, 29, 31, 32
Step-by-step explanation:
the number of workers he normally has + the number of extra workers he hires for harvesting = total number of employees
so 26+b=c
