Answer:
911,690.
Step-by-step explanation:
Please consider the complete question.
A city has a population of 390,000 people. Suppose that each year the population grows by 6.75%. What will the population be after 13 years? Round your answer the nearest whole number.
We will use exponential growth formula to solve our given problem.
, where,
y = Final value,
a = Initial value,
r = Growth rate in decimal form,
To find the population after 13 years, we will substitute 
in population growth equation as:
Upon rounding to nearest whole number, we will get:
Therefore, the population of the city after 13 years would be 911,690.
Answer:
<u>Use 2 points from he table to find the slope of f(x):</u>
<u>The slope is:</u>
The y - intercept is b = -1 according to point (0, -1).
<h3>Part A</h3>
<u>The lines are:</u>
- f(x) = 8x - 1
- g(x) = 3x - 2
The f(x) has greater slope since 8 > 3 and greater y-intercept since -1 > - 2.
<h3>Part B</h3>
See above
Answer:
the midpoint of segment is: 
Step-by-step explanation:
We need to find the midpoint of the segment (3,5) and (-6,-6)
Using the midpoint formula:
here x₁ = 3, x₂= -6, y₁=5 and y₂=-6
Putting values and finding the midpoint:
So, the midpoint of segment is:
Answer:
7 : 7 : 12 am
Step-by-step explanation:
This question pretty much requires us to obtain the lowest number that is common to all three times. The qay to obtain this is by finding the LCM of all three numbers.
This is given as;
48 = 2 × 2 × 2 × 2 × 3
72 = 2 × 2 × 2 × 3 × 3
108 = 2 × 2 × 3 × 3 × 3
The LCM is = 2 × 2 × 2 × 2 × 3 × 3 × 3 = 432 seconds.
Converting to minutes by dividing by 60, the time is = 432 ÷ 60 min = 7 min 12 sec
The next time they would change simultaneously is; 7am + 7 min 12 sec = 7 : 7 : 12 am
