The quotient of the division is calculated as follows;
( x² - 3x - 40 )/ (x² + 8x - 20) ÷ (x² + 13x + 40)/(x² + 12x + 20)
Factorize each of the expressions;
x² - 3x - 40
= x² + 5x - 8x - 40
= x(x + 5) - 8(x + 5)
= (x + 5)(x - 8)
x² + 8x - 20
= x² + 2x - 10x - 20
= x(x + 2) - 10(x + 2)
= (x + 2)(x - 10)
x² + 13x + 40
= x² + 5x + 8x + 40
= x(x + 5) + 8(x + 5)
= (x + 5)(x + 8)
x² + 12x + 20
= x² + 2x + 10x + 20
= x(x + 2) + 10(x + 2)

How do you convert this equation to rectangular form? The answer given in the book is (x-1)^2+y^2=9, but I need steps to show how you arrive at this answer.
The equation r²cos²(θ) - 2rcos(θ) + r²sin²(θ) = 8 to rectangular form is (x - 1)² + y² = 9
Converting the equation to rectangular form?From the question, we have the following parameters that can be used in our computation:
r²cos²(θ) - 2rcos(θ) + r²sin²(θ) = 8
The above equation is in its polar form, where
r² = x² + y²
cos(θ) = x/r
sin(θ) = y/r
Rearrange the terms in r²cos²(θ) - 2rcos(θ) + r²sin²(θ) = 8
So, we have
r²cos²(θ) + r²sin²(θ) - 2rcos(θ) = 8
Factorize
r²(cos²(θ) + sin²(θ)) - 2rcos(θ) = 8
In trigonometry
cos²(θ) + sin²(θ) = 1
So, we have
r² - 2rcos(θ) = 8
Recall that
r² = x² + y²
cos(θ) = x/r
So, we have
x² + y² - 2r * x/r = 8
Evaluate
x² + y² - 2x = 8
Rearrange
x² - 2x + y² = 8
Express as perfect squares
(x - 1)² + y² = 8 + 1
So, we have
(x - 1)² + y² = 9
Hence, the equation to rectangular form is (x - 1)² + y² = 9

The exponential function that models the relationship between the two points is [tex]y = 41.62 (1.0824)^x.[/tex]
We have,
To write an exponential model given two points (6,85) and (7,92), we can use the general exponential function form:
y = a[tex]b^x[/tex]
where y is the dependent variable, x is the independent variable, a is the initial value (when x = 0), and b is the base of the exponential function.
To find the values of a and b, we can use the two given points as follows:
When x = 6, y = 85:
85 = a b^6
When x = 7, y = 92:
92 = a b^7
We now have a system of two equations with two unknowns (a and b).
We can solve for a by dividing the second equation by the first equation:
92/85 = (ab^7) / (ab^6)
1.0824 = b
Substitute this value of b into one of the equations to solve for a:
85 = a (1.0824)^6
a = 41.62
Therefore,

The step that indicates the addition property of equality while solving the equation -1 - 6x = x - 15 is : (b) -1 - 6x + 15 = x - 15 + 15.
The "addition-property" of equality states that if we add the same quantity to both sides of an equation, the equation remains true.
In the equation -1 - 6x = x - 15, we need to isolate the variable term 'x'.
To isolate variable "x", we are adding 15 to both sides of the equation, which is the addition property of equality. This step simplifies the equation and isolate the variable "x" on one side.

(b) Calculate h-¹(90) and interpret its meaning in the context of the problem. Show your work. Round to 1 decimal.
The formula for the inverse function h⁻¹(P) is:
The population of insects in the lab experiment is 90, then the number of days it takes for the population to reach that size is approximately 17.5 days.
To find the inverse function h⁻¹(P), we need to solve the equation P = h(t) for t in terms of P.
Starting with P = h(t) = [tex]100/1+4e^-^0^.^0^5^t[/tex]
we can first multiply both sides by [tex]1+4e^-^0^.^0^5^t[/tex] to get:
[tex]P(1+4e^-^0^.^0^5^t) = 100[/tex]
t = -20ln(4/(P-100)+1)
Therefore, the formula for the inverse function h⁻¹(P) is:
h⁻¹(P) = -20ln(4/(P-100)+1)
(b) To find h⁻¹(90)
we substitute P = 90 into the formula for h^-1(P):
h⁻¹(90) = -20ln(4/(90-100)+1)
= 17.5
This means that if the population of insects in the lab experiment is 90, then the number of days it takes for the population to reach that size is 17.5 days.

Suppose you decide to invest in an annuity that pays 5% interest, compounded annually. How much money do you need to invest semiannually to reach a savings goal of $300,000 at the end of 25 years.
If your objective is to save $300,000 over 25 years, you would need to put away around $3077.41 every six months.
To solve this problem, we can use the formula for the future value of an annuity:
[tex]FV = P *\frac{((1 + r/n)^{(n*t)} - 1)}{(r/n)}[/tex]
where FV is the future value, P is the periodic payment, r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years.
Since the interest is compounded annually, we have n = 1 and r = 0.05. To find the periodic payment P, we can rearrange the formula:
P = FV * (r/n) / ((1 + r/n)^(n*t) - 1)
Plugging in the given values, we have:
[tex]P = 300000 * (0.05/2) / ((1 + 0.05/2)^{(2*25)} - 1)[/tex]
P ≈ $3077.41

The momentum change of the rock caused by its fall will be 35.49 x [tex]10{-24[/tex] m/sec and the magnitude of the earth velocity will be 212.94 kgm/s
We have,
Mass of the rock = 18 kg
Distance traveled = 7 m
Mass of earth = 6 x [tex]10^{24[/tex] Kg
Using second equation of motion
S= ut + 1/2 at²
If the body freely falls initial velocity will be zero.

Alondra wrote the following incomplete statement. 4.3 < 4. _____ Which of the following strategies could Alondra use to help her complete the statement? Select all that apply.
A. Write any decimal value with a number greater than 3 in the tenths place
B. Write any decimal value with a number greater than 3 in the hundredths place
C. Write any decimal value greater than 30 hundredths
D. Write any decimal value with 2 digits
E. Write any decimal value with a 3 in the tenths place
The strategies that Alondra can use to complete the statement include:
A. Write any decimal value with a number greater than 3 in the tenths placeB. Write any decimal value with a number greater than 3 in the hundredths placeC. Write any decimal value greater than 30 hundredthsWhy are these strategies best ?When a decimal number is created by Alondra and possesses 4 or more in the tenths place, it will exceed 4.3, as stated to exemplify decimals including 4.31 or 4.32.
Similarly, if there are 3 units plus a greater number appended behind the second digit after the decimal point (hundredths place). Deriving an outcome extending further than 4.30 can occur for any value above that obtained from inputting the numbers 4 and 3 into their respective positions in a given sequence.

On average, 66% of the days in Seattle, Washington, are cloudy or rainy. Describe a model that you could use to simulate this situation.
Since on average, 66% of the days in Seattle, Washington, are cloudy or rainy, a model that could be used to simulate this situation is an experimental probability model of about 2/3.
How to describe a model that you could use to simulate this situation?In this scenario and exercise, you are to required to describe a model that you could be used to simulate a situation in which 66% of the days in Seattle, Washington, are cloudy or rainy on an average.
In this context, we can reasonably infer and logically deduce that the most accurate and feasible model to use would be an experimental probability model of about 2/3;
66% = 66/100 = 33/50 ≈ 2/3.
In conclusion, you should select two (2) red marbles that each represent cloudy or rainy days and one (1) blue marble that represent non-cloudy or non-rainy days, and then pick one marble randomly. Repeat several times in order to determine experimental probability that a day would either be cloudy or rainy.

Fernando also learns in math class that the rule Add 1 to the side length of a pentagon with equal sides length results the rule Add 5 to the perimeter. Write four ordered pairs that relate the side length of a pentagon to the perimeter of the pentagon.
All the four ordered pairs that relate the side length of a pentagon to the perimeter of the pentagon are,
⇒ (1, 5) (2, 10) (3, 15) (4, 20)
Given that;
Fernando also learns in math class that the rule Add 1 to the side length of a pentagon with equal sides length results the rule Add 5 to the perimeter.
Now,
Here are four ordered pairs that relate the side length of a pentagon to the perimeter of the pentagon:
⇒ (1, 5) (2, 10) (3, 15) (4, 20)
Hence, In each pair, the first number represents the side length of the pentagon, and the second number represents the perimeter of the pentagon.
And, If you add 1 to the side length in each pair, you'll see that the perimeter increases by 5, just as Fernando learned in math class.
