Answer:
l1-l2 = distance
Step-by-step explanation:
It would take 21 years for the population of Boomtown to reach 1 million people.
An exponential growth is in the form:
y = abˣ;
where y, x are variables, a is the initial value of y and b is > 1
Let y represent the population of Boomtown after x years.
Given that initially there is a population of 475,000, hence a = 475000. Also, it is increasing at a rate of 3.75%, hence b = 100% + 3.75% = 1.0375
Hence:
y = 475000(1.0375)ˣ
For a population of 1000000:
1000000 =475000(1.0375)ˣ
2.1 = (1.0375)ˣ
xln(1.0375) = ln(2.1)
x = 21 years
Hence it would take 21 years for the population of Boomtown to reach 1 million people.

After 20.22 years the population exceed 1 million people, if the population of Boomtown is 475,000 and is increasing at a rate of 3.75% each year.
Step-by-step explanation:
The given is,
Population of Boomtown is 475,000
Increasing at a rate of 3.75% each year
After few years population exceed 1 million people
Step:1
Formula to calculate population with a given rate of increase,
..............................(1)
Where,
F - Population after t years
P - Population at initial
r - Rate of increase
t - No.of years
From the given values,
F = 1000000
P = 475,000
r = 3.75%
Equation (1) becomes,
Take log on both sides,
Substitute log values,
= 20.2216
t ≅ 20.222 years
Result:
After 20.22 years the population exceed 1 million people, if the population of Boomtown is 475,000 and is increasing at a rate of 3.75% each year.
Answer:
c. 40.
Step-by-step explanation:
Since the small and large triangles are similar we have the equation:
45 / 90 = 6x + 4 / 4x + 56
1 /2 = 6x + 4 / 4x + 56
2(6x + 4) = 4x + 56
12x + 8 = 4x + 56
8x = 48
x = 6
So the length of the mid segment = 6(6) + 4 = 40.
