If the population of a certain county was 100,000 in 1998 and 110,429 in 2008, and if the formulay = P0ehtapplies to the growth of the county's population, estimate the population of the county in 2023. (P0 is the initial population. Round your value of h to four decimal places. Round your answer to the nearest whole number.)
Answer:
126807 people
Step-by-step explanation:
Given;
P= Poe^ht
Where;
P= population at time t
Po= population at the beginning
h= growth constant
t= time
1998- 2008 is ten years.
110429= 100,000e^10h
1.1 = e^10h
ln(1.1) = lne^10h
0.095 = 10h
h= 0.0095
In 2023, t = 25 years
P= 100,000e^(0.0095 × 25)
P= 126807 people

What's the solution to -182=2(1+2x)-2
Answer: [tex]x = -\frac{91}{2}[/tex]
Step-by-step explanation:
If you have any questions, feel free to ask :)
Step 1: Add [tex]2[/tex] to both sides.
[tex]-182 + 2 = 2(1 + 2x)[/tex]
Step 2: Simplify [tex]-182 + 2[/tex] to [tex]-180[/tex].
[tex]-180 = 2(1 + 2x)[/tex]
Step 3: Divide both sides by [tex]2[/tex].
[tex]-\frac{180}{2} = 1 + 2x[/tex]
Step 4: Simplify [tex]\frac{180}{2}[/tex] to [tex]90[/tex].
[tex]-90 = 1 + 2x[/tex]
Step 5: Subtract [tex]1[/tex] from both sides.
[tex]-90 - 1 = 2x[/tex]
Step 6: Simplify [tex]-90 - 1[/tex] to [tex]-91[/tex].
[tex]-91 = 2x[/tex]
Step 7: Divide both sides by [tex]2[/tex].
[tex]-\frac{91}{2} = x[/tex]
Step 8: Switch sides.
[tex]x = -\frac{91}{2}[/tex]

3. Which expression is equivalent to 1+2(x-1)
Answer:
2x - 1
Step-by-step explanation:
Equivalent Algebraic Expressions
One algebraic expression can be written in several ways by applying known rules and theorems that modify expressions without changing its final value.
The expression:
1 + 2(x - 1)
Can be modified by applying the following operations:
Multiplying the constant by the contents in parentheses:
1 + 2x - 2
Collecting like terms:
-1 + 2x
Or, equivalently:
2x - 1

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (6, -3). What is the vertex of the function defined as
g(x) = f(-x) - 3?
Answer: (-6, - 6)
Step-by-step explanation:
Here we have two transformations, and the first step will be to explain those transformations:
Reflection over the y-axis.
For a function f(x), the reflection over the y-axis is written as:
g(x) = f(-x)
Then if we initially had a point (x, y), the transformed point will be (-x, y).
Vertical translation.
We can define a vertical translation of N units as:
g(x) = f(x) + N
if N > 0, the translation is up.
If N < 0, the translation is down.
Then if we start with a point (x, y), the transformed point will be (x, y + N)
In the case of this problem we have g(x) = f(-x) - 3
This means that N = -3
Then if we initially had the vertex at the point (6, - 3)
The transformed point will be: changing the sign of the x-component and subtracting 3 in the y-component, then the transformed vertex point is:
(-6, -3 - 3) = (-6, - 6)
The vertex of the resulting parabola will be (-6, -6)
Rule of reflectionGiven the function y= f(x), plotted on a graph and the vertex of the resulting
parabola is (6, -3), if this coordinate is reflected over the y-axis, the reflection rule will be:
[tex](x,y) \rightarrow (-x, y)[/tex]The coordinate (6, -3) under this translation will give (-6, -3)To get the corresponding function [tex]g(x) = f(x) - 3\\[/tex]
[tex]g(x) = [(-6, -3) - 3]\\g(x) = (-6, -3-3)\\g(x) =(-6, -6)[/tex]
Hence the vertex of the resulting parabola will be (-6, -6)

A plane set off to Portland at a speed of 232 mph. On the
return flight of 12 hours, the plane cruised at 204 mph.
How many hours long was the flight to Portland?
Answer:
The flight to Portland takes 10.6 hours.
Step-by-step explanation:
To find the time of flight to Portland we need to calculate the distance traveled by using the equation:
[tex] x = v*t [/tex]
Where:
v: is the speed = 204 mph (return flight)
t: is the time = 12 h (return flight)
[tex] x = v*t = 204 mi/h*12 h = 2448 mi [/tex]
Now, we can find the time of flight to Portland using v = 232 mph:
[tex]t = \frac{x}{v} = \frac{2448 mi}{232 mi/h} = 10.6 h[/tex]
Therefore, the flight to Portland takes 10.6 hours.
I hope it helps you!
