The answer would be 55,500.
Take a look at the function: y = 60,000 - 500x.
- 500 (x) indicates that by each year the population of the town will decrease by a total of 500 residents.
So after 9 years, 4,500 residents should no longer be residing there.
To figure this out,
Multiply 9 and 500, which as a result you should get 4,500.
Then subtract 4,500 from 60,000.
The ending result would be 55,500.
Answer:
The population of the town after 9 years would be 55,000 residents.

okey i will help you what is that
Answer:
(i) The name of the part of the circle, OQ is a radius
(ii) The radius of the sector QOR is 21 cm
Step-by-step explanation:
The given figure is a sector of the circle O
∵ Any sector of a circle formed from 2 radii and an arc
∴ OQ is a radius
(i) The name of the part of the circle, OQ is a radius
The rule of the length of an arc of a circle is L =
× 2 π r, where
- α is the angle of the sector
- r is the radius of the circle
∵ The length of the arc QR is 22 cm
∴ L = 22
∵ The measure of the angle of the arc is 60°
∴ α = 60°
∵ π = ![\frac{22}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B22%7D%7B7%7D)
→ Substitute them in the rule above
∵ 22 =
× 2 ×
× r
∴ 22 =
r
→ Divide both sides by ![\frac{22}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B22%7D%7B21%7D)
∴ 21 = r
(ii) The radius of the sector QOR is 21 cm
P = 6s
42a +18 = 6s
s = 7a + 3
s is the side of hexagon
p is the perimeter of the hexagon
