Answer:

  • Options 1 and 3 are direct variation

Step-by-step explanation:

<u>Direct variation is:</u>

  • y = kx

<u>Options:</u>

1.

  • y = -x, k = -1, yes

2.

  • y = 2x + 3, not a direct variation, no

3.

<u>Try the input/output to determine the direct variation:</u>

  • 4 = 3k
  • k = 4/3

<u>Verify the other pairs:</u>

  • x = 6, y = 6(4/3) = 8
  • x = 9, y = 9(4/3) = 12
  • x = 12, y = 12(4/3) = 16
  • x = 15, y = 15(4/3) = 20

This is also a direct variation

In 2015, the population of a small town in Florida is 95. If he population increases 15% every year, approximately what will the
vova2212 [387]

The population is increasing every year. so we use exponential growth function

y=a(1+r)^x

Where 'a' is the initial population

r is the rate of increase

x is the years

y is the final population

In 2015, the population of a small town in Florida is 95

Initial population a= 95

r= 15%= 0.15

x = 2023 - 2015 = 8 years

Plug in all the values and find out y

y=a(1+r)^x

y=95(1+0.15)^8

y = 290.607

The population in 2023 is 291
