Population growth the population of knoxville is 500,000 and is increasing at the rate of 3.75% each year. approximately when wi

Shalnov [3]

Current population = 500,000
Populaton is
500,000 * (1.0375) after 1 year
500,000 * (1.0375)² after 2 years
...
500,000 * (1.0375)ˣ after x years

Therefore when the population reaches a million,
500,000 * (1.0375)ˣ = 1,000,000
1.0375ˣ = 2
x ln(1.0375) = ln(2)
x = ln(2) / ln(1.0375) = 18.83 years

Answer: 18.8 years, or approximately 19 years.

The variables y and x have a proportional relationship, and y = 15 when x = 3. What is the value of x when y = 4?

Akimi4 [234]

Answer:

$x=\frac{4}{5}=0.8$

Step-by-step explanation:

We have been given that the variables y and x have a proportional relationship, therefore, we can represent the relationship between x and y as: $y=kx$ , where k is proportionality constant.

Let us substitute x=3 and y=15 in above equation to find the value of k.

$15=k*3$

$k=\frac{15}{3}$

$k=5$

Now let us substitute k=5 and y=4 in our proportionality equation to find the corresponding value of x.

$4=5x$

$x=\frac{4}{5}$

$x=0.8$

Therefore, the value of x will be 0.8, when y equals to 4.
