How to determine the straight-line distance?In order to determine the straight-line distance from your starting point, we would apply Pythagorean's theorem. Mathematically, Pythagorean's theorem is given by this mathematical expression:
c² = a² + b²
Where:
a, b, and c represents the side lengths of a right-angled triangle.
c² = 12² + 2²
c² = 144 + 4
c = √148
c = 12.17 miles.
In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).
Midpoint = [(x₁ + x₂)/2, (y₁ + y₂)/2]
Midpoint = [(6 + 2)/2, (4 + 2)/2]
Midpoint = [8/2, 6/2]
Midpoint = [4, 3]
Midpoint = [(x₁ + x₂)/2, (y₁ + y₂)/2]
Midpoint = [(2 + 4)/2, (3 + 1)/2]
Midpoint = [6/2, 4/2]
Midpoint = [3, 2]
By applying the midpoint formula, the sales for 1997 can be calculated as follows;
Sales = (1996 sales + 1998 sales)/Number of years
Sales = ($500,000 + $720,000)/2 years
Sales = $1,220,000/2
Sales = $610,000.

prove that if if events a and b are independent, then they are also independent conditioned onevent c.
If events A and B are independent, then they remain independent when conditioned on event C.
To prove that if events A and B are independent, then they are also independent conditioned on event C, we can use the definition of conditional probability.
Recall that two events A and B are independent if and only if P(A and B) = P(A) * P(B). And the conditional probability of A given B can be calculated as P(A | B) = P(A and B) / P(B).
It follows that P(A and B) = P(A) * P(B) if occurrences A and B are independent. Substituting this into the expression for conditional probability, we get:
[tex]P(A | B) = P(A) * P(B) / P(B) = P(A)[/tex]
Similarly, we can prove that P(B | A) = P(B). This means that the probability of A and B given event C are equal to the probabilities of A and B, respectively, given that A and B are independent. Hence, events A and B are also independent conditioned on event C

Wendy will have new carpet installed on her rectangular bedroom floor. The floor is 15 feet in length and 12 feet in width. The carpet costs $27.50 per square yard, and installation costs $4.15 per square yard. Which statement about the total cost of the carpet and installation is true?
a. The total cost is $379.80 since $31.65×12 = $379.80.
b. The total cost is $633.00 since $31.65×20 = $633.00.
c. The total cost is $474.75 since $31.65×15 = $474.75.
d. The total cost is $4,950.00 since $27.50×180 = $4,950.00
The statement that is true about the total cost of the carpet and installation is: The total cost of the carpet and installation is $633.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
To determine the total cost of the carpet and installation, we first need to calculate the area of Wendy's bedroom floor, which is:
Area = Length x Width
Area = 15 ft x 12 ft
Area = 180 square feet
We can then convert the area to square yards by dividing by 9:
Area in square yards = 180 sq ft / 9
Area in square yards = 20 sq yd
The cost of the carpet is $27.50 per square yard, so the cost of the carpet alone is:
Carpet cost = 20 sq yd x $27.50/sq yd
Carpet cost = $550
The installation cost is $4.15 per square yard, so the cost of the installation alone is:
Installation cost = 20 sq yd x $4.15/sq yd
Installation cost = $83
To find the total cost, we need to add the cost of the carpet and the installation
Total cost = Carpet cost + Installation cost
Total cost = $550 + $83
Total cost = $633
Therefore, the statement that is true about the total cost of the carpet and installation is: The total cost of the carpet and installation is $633.

The parametric equation of a line segment joining two points (x1, y1) and (x2, y2) is given by [tex]x = x1 + t(x2 - x1) and y = y1 + t(y2 - y1)[/tex]. Here, t is a real variable and its value lies between 0 and 1. This is because when t = 0, the equation gives the coordinates of the first point (x1, y1) and when t = 1, the equation gives the coordinates of the second point (x2, y2). For example, if the two points are (3, 4) and (7, 8), then the parametric equation of the line segment joining them can be obtained as [tex]x = 3 + t(7 - 3) = 3 + 4t and y = 4 + t(8 - 4) = 4 + 4t[/tex].

A Ferris wheel is 24 meters in diameter and is boarded from a platform that is 1 meter above the ground. The six o'clock position on the Ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 16 minutes. The function h (t) gives a person's height in meters above the ground t minutes after the wheel begins to turn.
a. Find the amplitude, midline, and period of h (t).
b. Assume that a person has just boarded the Ferris wheel from the platform and that the Ferris wheel starts spinning at time t=0. Find a furmula for the height function h(t).
c. If the Ferris whell continues to turn, how high off the ground is a person after 52 minutes?
a. The amplitude is 12m, the midline is 13m, and the period of h (t) is 16 minutes.
How to solve these?a. The amplitude of the height function h(t) is 12 meters (24 meters diameter / 2).
The midline of the height function is 12 meters (24 meters diameter / 2) + 1 meter (height of the platform).
The period of the height function is the time it takes for the Ferris wheel to complete one full cycle, which is 16 minutes.
b. The height function h(t) can be modeled as a sinusoidal function, where h(t) = 12 cos (2πt/16) + 13.
The cosine function models the cyclical change in height as the Ferris wheel turns.
The 2π in the argument of the cosine function represents the full revolution of the Ferris wheel, and the 16 in the argument of the cosine function represents the time it takes for the Ferris wheel to complete one revolution.
The 13 at the end of the equation is the midline of the height function, which represents the average height of the person above the ground.
c. To find the height of a person after 52 minutes, we substitute t = 52 into the height function h(t) = 12 cos (2πt/16) + 13:
h(52) = 12 cos (2π x 52/16) + 13
h(52) = 12 cos (13π) + 13
h(52) = 12(-1) + 13
h(52) = 1 meter
So, a person would be 1 meter above the ground after 52 minutes.

Given that an investment into a college fund is represented by A=12,000e^(0.023*12) , match each value to the correct description of the value in the context of the question. 12,000 The amount of money in the account at the end of the time given. e
The initial amount of money invested into the college fund 0.023
The interest rate.
The interest is compounded continuously.
The amount of years the money is invested.
As per compound interest, the account balance at the end of 12 years is approximately $17,217.
Compound interest is an important concept in finance and investing, and it plays a critical role in understanding how your money can grow over time. When you invest money, your initial investment earns interest, and over time, that interest can also earn interest, resulting in exponential growth.
In the context of this question, the investment into a college fund is represented by the equation
=> [tex]A = 12,000e^{0.023*12}[/tex]
where A is the amount of money in the account at the end of the time given. Let's break down the different components of this equation and see how they relate to compound interest.
First, we have the initial investment, which is not explicitly given in the equation, but we can infer that it is 12,000. This is the amount of money that is initially invested into the college fund.
Next, we have the interest rate, which is 0.023.
Finally, we have the amount of time that the money is invested, which is 12 years in this case. The longer the money is invested, the more time there is for compound interest to work its magic and grow the account balance.
Putting all of these components together, we can use the equation
=> [tex]A = 12,000e^{0.023*12}[/tex]
to calculate the amount of money in the college fund at the end of 12 years.
By plugging in the values for the initial investment, interest rate, and time, we can see that the account balance at the end of 12 years is approximately $17,217.
This represents the power of compound interest and how it can turn a modest initial investment into a substantial sum over time.

(c) Revolving about the line x=3, the volume of the solid is 0
(d) Revolving about the line x=6, the volume of the solid will be 32/3 Pi
The region bounded by y=x, y=0, and x=3 is a triangle in the first quadrant.
To find the volume of the solid generated by revolving this region about an axis, we can use the disk or washer method.
(a) Revolving about the x-axis:
Each cross-section of the solid perpendicular to the x-axis is a disk with radius x and thickness dx.
The volume of each disk is [tex]\pi x^2 dx[/tex].
The limits of integration are 0 and 3, the x-coordinates of the intersection points of the two curves.
Hence, the volume of the solid is
[tex]V &= \int_0^3 \pi x^2 dx\\\\\&= \left[\frac{\pi}{3}x^3\right]_0^3\\\\\&= \frac{9\pi}{3}\\\\\&= 3\pi.[/tex]
(b) Revolving about the y-axis:
Each cross-section of the solid perpendicular to the y-axis is a washer with outer radius 3 and inner radius x, and thickness dx.
The volume of each washer is [tex]\pi(3^2-x^2)dx.[/tex]
The limits of integration are 0 and 3.
Hence, the volume of the solid is
[tex]V &= \int_0^3 \pi(3^2-x^2)dx\\\\\&= \left[\pi(9x-\frac{x^3}{3})\right]_0^3\\\\\&= \pi(27-\frac{27}{3})\\\\\&= 18\pi.[/tex]
(c) Revolving about the line x=3:
Each cross-section of the solid perpendicular to the line x=3 is a washer with outer radius 3-x and inner radius 3-x-|x|, and thickness dx.
The volume of each washer is[tex]\pi((3-x)^2-(3-x-|x|)^2)dx[/tex].
The limits of integration are -3 and 3.
Hence, the volume of the solid is
[tex]V &= \int_{-3}^3 \pi((3-x)^2-(3-x-|x|)^2)dx\\\\\&= \left[8\pi\int_0^3 (3-x-|x|)dx\right]\\\\\&= 8\pi\int_0^3 (3-2x)dx\\\\\&= 8\pi\left[3x-x^2\right]_0^3\\\\\&= 8\pi(9-9)\\\\\&= 0.\\\\[/tex]
(d) Revolving about the line x=6:
Each cross-section of the solid perpendicular to the line x=6 is a washer with outer radius |3-x| and inner radius |x-6|, and thickness dx.
The volume of each washer is[tex]\pi(|3-x|^2-|x-6|^2)dx.[/tex]
The limits of integration are 0 and 3.
Hence, the volume of the solid is

As a result of this development, the planners have estimated that Glen Clove's population (in thousands) t yr from now will be given by the following function.P(t) = 35t^2 + 125t + 200/t^2 + 4t + 40(a) What is the current population of Glen Cove? (b) What will be the population in the long run?
The current population of Glen Cove is 5,000 people and in the long-run, the population of Glen Cove will approach 35,000 people.
Corporation:A corporation may be a corporate entity whose shareholders elect a board of directors to supervise its operations. the dissimilarity between the business and an organization is that an organization may be a sort of business that's suitable for smaller businesses and organizations, whereas a corporation may be a kind of business that's appropriate for larger enterprises and entities.
The population in Glen Clove's population that is t years from now will be
P(t) = [tex]\frac{35t^2 + 125t + 200}{t^2 + 4t + 40}[/tex]
The current population can be calculated by substituting t = 0 in P(t).
So,
P(0) = [tex]\frac{35(0)^2 + 125(0) + 200}{(0)^2 + 4(0) + 40}[/tex]
P(0) = 5
Thus, the current population of Glen Clove is 5 thousand.
(b)For the long run, t tends to infinity. So, evaluate the infinite limit for the given function as follows:
[tex]\lim_{t \to \infty} P(t)= \lim_{t \to \infty}P(t)\frac{35t^2 + 125t + 200}{t^2 + 4t + 40}[/tex]
=[tex]\lim_{t \to \infty}\frac{t^2(35+\frac{125}{t} +\frac{200}{t} )}{t^2(1+\frac{4}{t} +\frac{40}{t^2} )}[/tex]
= [tex]\lim_{t \to \infty}\frac{(35+\frac{125}{t} +\frac{200}{t} )}{1+(\frac{4}{t} +\frac{40}{t^2} )}[/tex]
Now, solve further by putting the limits as follows:
As t approaches infinity, the terms in the numerator approach 0, while the terms in the denominator approach 1, so the limit of P(t) as t approaches infinity is:
lim t -> infinity P(t) = 35 / 1 = 35
So, in the long-run, the population of Glen Cove will approach 35,000 people.

S A black bear was tracked across Central Florida logging approximately 120 miles in 30 days.
For 24 miles of M34’s journey, he was tracked walking along the Kissimmee River.
How many days was he traveling along the Kissimmee River?
Answer: 6 days
120 miles divided into 30 days is 4 miles per day.
24 miles divided by 4 miles is 6 , which means the bear spent 6 days walking along Kissimmee River.

We determined that the unconditional probability distribution for Y, the number of defects per yard in a certain fabric, is P(y) = - (1/2)^y+1 y = 0, 1, 2, .... Find the expected number of defects per yard.
The expected number of defects per yard is 1.
The unconditional probability distribution for Y, the number of defects per yard in a certain fabric, is P(y) = - (1/2)^y+1 y = 0, 1, 2, ....
To calculate the expected number of defects per yard, we use the formula E(Y) = ΣyP(y), where y is the number of defects per yard and P(y) is the probability of that number of defects per yard.
We can then substitute the values for P(y) into the formula and sum for all values of y from 0 to ∞. This yields E(Y) = Σy(-(1/2)^y+1) = 1. Thus, the expected number of defects per yard is 1.
