Answer:
The required formula is:
Step-by-step explanation:
Consider the provided information.
A city's population was 28,600 people in the year 2015 and is growing by 950 people a year.
Let t is the number of years since 2015, and the population of city is denoted by p,
Each yr population is growing by 950.
That means for t yr since 2015 population will grow 950t
In 2015 the population was 28,600

Answer:
3 times more.
Step-by-step explanation:
The odds of landing a dart in any of the circles correspond to the surface area of the circle.
Calculate the surface area of both circles:
The formula for the area of a circle is .
- inner circle:
- for the outer circle, use the formula then subtract the value of the inner circle, to find the remaining area:
Calculating greater chance:
Divide the larger area by the smaller area:
That means that the area of the outer circle is 3 times larger, making it 3 times more likely to hit the outer circle. Therefore the points for hitting the inner circle should be 3 times more.
