Answer:
$10576.38
Step-by-step explanation:
To calculate the investment amount required to produce $23711 at an interest rate of 3.6% compounded monthly for 15 years, you can use the formula for compound interest:
A = P * (1 + r/n)^(nt)
where:
A is the amount of money you have after "t" years,
P is the initial investment amount (what you want to find),
r is the interest rate as a decimal,
n is the number of times the interest is compounded per year,
t is the number of years the investment will be compounded for.
In this case,
r = 0.036
n = 12 (because the interest is compounded monthly)
t = 15
So, we can plug in the values into the formula and solve for P:
A = P * (1 + 0.036/12)^(12 * 15)
$23711 = P * (1.003)^(180)
$23711 = P * 2.2375
Dividing both sides by 2.2375:
P = $23711 / 2.2375
P = $10576.38
So, to produce $23711 at an interest rate of 3.6% compounded monthly for 15 years, you would need to invest $10576.38. Rounded to the nearest dollar, this amount is $10576.

CJ has three more pet pigs than Jacqui has. Let’s write an expression to represent how many pigs CJ has. To do that, we follow these steps:
Identify the constants and the variables.
There is one known number or constant here: it is 3. CJ has 3 more pigs than Jacqui. That number, 3, won’t change. The variable is the number of pets Jacqui has. Let’s call that j.
Identify the operations.
The phrase “more than” tells us we need to add. There are no other operations in this expression.
Rewrite the phrase as an expression.
“Three more pet pigs than Jacqui has” is 3 + j.

Endpoints of a diameter are (−5,−11) and (−1,1) Find the standard form of the equation for the circle with the following properties.
Answer:
Standard form of the equation for the circle
(x + 3)² + (y + 5)² = 40
Step-by-step explanation:
The equation of a circle in standard form is
[tex]\boxed{(x - a)^2 + (y-b)^2= r^2}[/tex]
where (a, b) is the center of the circle and r is the radius
To find center of circle
The end points of the diameter are (-5, -11) and (-1, 1)
The center of the circle is midway between these two points
The x-coordinate of the midpoint = (-5 + -1)/2 = -6/2 = -3
The y-coordinate of the midpoint is (-11 + 1) /2 = -10/2 = -5
So the center of the circle is at (-3, -5)
To find the radius,
Calculate the distance from (-3, -5) to any of of the endpoints.
Let's take the endpoint (-1, 1) and find its distance from (-3, -5)
The distance between any two points (x₁, y₁) and (x₂, y₂) is calculated from the formula
[tex]d^2 = {(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2[/tex]
Substituting
(x₁, y₁) = (-1, 1)
(x₂, y₂) = (-3, -5)
and r for distance
we get
[tex]r^2 = {(-3 - (-1))^2 + (-5 - 1)^2[/tex]
[tex]r^2 = {(-2)^2 + (-6)^2}[/tex]
[tex]r^2 = {{4} + {36}}[/tex]
[tex]r^2 = {40}[/tex]
So the center (a, b) is (-3, -5) and r² =40
Plugging this into the circle equation:
(x - (-3))² + (y - (-5))² = 40
(x + 3)² + (y + 5)² = 40

A car travels 55 mph and passes a truck travelling 50 mph. How long will it take the car to be
more than 23 mi ahead?
Answer:you never asked for like in what minutes or hours?
Step-by-step explanation:
The car, traveling at a speed 5 mph faster than the truck, will take more than 4.6 hours to be more than 23 miles ahead.
Explanation:This question pertains to relative speed. When the car is traveling at 55 mph and the truck at 50 mph, the car is effectively moving away from the truck at (55 mph - 50 mph) = 5 mph. To calculate the time it will take for the car to be more than 23 miles ahead, we can use the formula: Time = Distance/Speed. So the time it would take is Time = 23 miles / 5 mph = 4.6 hours. Therefore, it will take the car more than 4.6 hours to be more than 23 miles ahead.

The function operation (f/g)(x) in the functions f(x) = √( x² - 1 ) and g(x) = √( x - 1 ) is √( x + 1).
What is the function operation (f/g)(x) in the function?A function is simply a relationship that maps one input to one output.
Given the functions in the question;
f(x) = √( x² - 1 )g(x) = √( x - 1 )(f/g)(x) = ?To evaluate (f/g), replace the function designators in f/g with the actual functions.
(f/g)(x) = f(x) / g(x)
(f/g)(x) = ( √( x² - 1 ) ) / ( √( x - 1 ) )
Now, rewrite 1 as 1²
(f/g)(x) = ( √( x² - 1² ) ) / ( √( x - 1 ) )
Factor using difference of square
(f/g)(x) = ( √( (x - 1)(x + 1 ) ) / ( √( x - 1 ) )
Combine into a single radical
(f/g)(x) = √( ( (x - 1)(x + 1) ) / ( x - 1 ) )
Now, cancel out the common factors (x-1)
(f/g)(x) = √( (x + 1) / 1 )
(f/g)(x) = √( x + 1)
Therefore, the function operation (f/g)(x) is √( x + 1).
Option A) √( x + 1) is the correct answer.

One cubic foot holds 7.48 gallons of water, and 1 gallon of water weighs 8.33 pounds. How much does 4.4 cubic feet of water weigh in pounds? In tons?
Answer:
4.4 cubic feet of water weighs approximately 273.5016 pounds or 0.13676 tons.
Step-by-step explanation:
To find the weight of 4.4 cubic feet of water in pounds, we need to find the number of gallons it contains and then multiply it by the weight of one gallon of water.
1 cubic foot = 7.48 gallons
So, 4.4 cubic feet = 4.4 * 7.48 = 32.912 gallons
And the weight of 32.912 gallons of water in pounds is:
32.912 gallons * 8.33 pounds/gallon = 273.5016 pounds
To convert this weight to tons, we divide the weight in pounds by 2000:
273.5016 pounds / 2000 = 0.13676 tons
So, 4.4 cubic feet of water weighs approximately 273.5016 pounds or 0.13676 tons.

The reasons for (1) and (2) are added below
Why it is reasonable to use a linear functionOne reason why it might be reasonable to model the relationship between time and height of the candle with a linear function is that the rate of change of the candle's height appears to be constant over time.
Why it is unreasonableOne reason why it might NOT be reasonable to model this relationship with a linear function is that the candle's height cannot continue to decrease indefinitely.

Use the dropdowns to complete the statements.
In the equation, the number 5,000 represents the ________ of the motorcycle. The value of the motorcycle is __________ at a rate of ________ per year.
In the equation, the number 5,000 represents the initial value of the motorcycle. The value of the motorcycle is increasing at a rate of 3% per year.
What are Exponential Functions?Exponential functions are functions where the independent variable, x is in the exponent.
The given exponential equation is,
V = 5,000 (1.03)^t
Here V represents the value of the motorcycle in t years.
When t = 0,
V = 5000 (1.03)⁰ = 5000
So 5000 represents the initial value of the motorcycle.
V = 5,000 (1 + 0.03)^t
At t = 0, V = 5000
At t = 1, V = 5000 (1.03)¹ = 5150
At t = 2, V = 5000 (1.03)² = 5304.5
So the value of the motorcycle is increasing.
The rate is 0.03 or 3%.
Hence, 5,000 represents the initial value of the motorcycle and the value of the motorcycle is increasing at a rate of 3% per year.

The equations of the parabolas are y = x² - 6x - 7 and y = x² - 7
How to determine the equation of the parabolasParabola 1
Given that

The equation is represented as
y = ax² + bx + c
So, we have
a - b + c = 0
49a + 7b + c = 0
9a + 3b + c = -16
Make c the subject in a - b + c = 0
c = b - a
So, we have
49a + 7b + b - a = 0
9a + 3b + b - a = -16
48a + 8b = 0
8a + 4b = -16
Multiply 8a + 4b = -16 by 2
48a + 8b = 0
16a + 8b = -32
Subtract
32a = 32
So, we have
a = 1
Recall that 48a + 8b = 0
So, we have
48 + 8b = 0
This gives
8b = -48
Divide
b = -6
Also, we have
c = b - a
This gives
c = -6 - 1
c = -7
So, the equation is

Parabola 2
Given that
The points (-4,9), (-3, 2) and (0,-7) and (4,9)
The equation is represented as
y = ax² + bx + c
So, we have

9a - 3b + c = 2
c = -7
16a + 4b + c = 9
The equations become
16a - 4b = 16
9a - 3b = 9
16a + 4b = 16
Add (1) and (3)
32a = 32
So, we have
