The Slope of the line passing through the points (-2, -3) and (-4, -9) is 3.
The slope of a line, we can use the formula:
slope = (change in y) / (change in x)
Given the coordinates of two points on the line: (-2, -3) and (-4, -9), we can calculate the slope.
Let's denote the coordinates of the first point as (x₁, y₁) = (-2, -3) and the coordinates of the second point as (x₂, y₂) = (-4, -9).
The change in y is equal to y₂ - y₁, and the change in x is equal to x₂ - x₁.
change in y = -9 - (-3) = -9 + 3 = -6
change in x = -4 - (-2) = -4 + 2 = -2
Now we can substitute these values into the slope formula:
slope = (-6) / (-2)
To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 2:
slope = 6 / 2
Simplifying further:
slope = 3
Therefore, the slope of the line passing through the points (-2, -3) and (-4, -9) is 3.

Answer:

Step-by-step explanation:
Let the sides of a triangle be a, b, and c, where a < b < c. Then, we know that a + b > c. If we use this identity to solve this problem, then we can find that answer choice b does not satisfy it. Thus, b does NOT have the lengths of a triangle.
Part A
Study the two functions shown, A(t) and 12∙J(t). Based on the graph and the data, what kinds of functions are they? Choose among linear, quadratic, and exponential. Describe the features of each function that gave you clues.
15px
Space used (includes formatting): 134 / 15000
Part B
The equation A = Pert describes a bank loan that compounds continuously. The variables in the equation are described in the table:
Variable Definition
A This is the principal and interest on the loan. Principal is the amount of money borrowed. Interest is a graduated fee paid to the bank for the privilege of borrowing its money.
P This is the principal, or the amount of money borrowed. Don’t confuse P in the compounding interest equation with P in the profit equation. One is principal, the other is profit.
e This is Euler’s number, e ≈ 2.7, used in exponential functions that are continuously compounding.
r This is the interest rate expressed as a percentage.
t This is the time allotted, in years, to repay the loan. It’s also called the life of the loan.
For the sake of this activity, assume that you will collect profit from sales for a number of months and then use a portion of that profit to pay off the entire loan in one lump-sum payment once the loan terminates. Based on this assumption, what does the intersection of the 12∙J(t) curve and the A(t) curve represent? Explain using your own words.
15px
Space used (includes formatting): 0 / 15000
Part C
Take some time to gradually increase P in increments of $100,000 while keeping r and J(t) constant. What happens to the relationship between the two curves? What does this mean with respect to the bank loan? Why is this a dangerous situation with respect to the financial health of your business? Why would banks put safeguards in place to prevent this from occurring?
15px
Part A:
A(t) is a linear function, and 12∙J(t) is an exponential function. The straight line nature of A(t) indicates linear growth, while the curve of 12∙J(t) suggests exponential growth.
Part B:
The intersection of the 12∙J(t) curve and the A(t) curve represents the point where the accumulated profit from sales is sufficient to pay off the entire loan in one lump-sum payment.
Part C:
As P increases while keeping r and J(t) constant, the relationship between the two curves shifts, indicating a higher profit requirement to cover the increased loan amount. This is dangerous for business financial health and banks have safeguards to prevent excessive debt and defaults.
Part A:
From the given information, we have two functions: A(t) and 12∙J(t). Let's analyze their features to determine their types.
A(t) is a linear function:
A linear function is characterized by a constant rate of change and forms a straight line on a graph.
In the given graph, A(t) is represented by a straight line, indicating a linear relationship between the variables.
This suggests that A(t) is a linear function.
12∙J(t) is an exponential function:
An exponential function is characterized by a constant ratio or base and shows exponential growth or decay.
In the given graph, 12∙J(t) is represented by a curve that exhibits exponential growth.
The increasing rate of change as time progresses indicates an exponential relationship.
Therefore, 12∙J(t) is an exponential function.
Part B:
The intersection of the 12∙J(t) curve and the A(t) curve represents the point at which the profit generated from sales is sufficient to pay off the entire loan in one lump-sum payment. In other words, it represents the point in time when the accumulated profit matches the amount of the loan.
At this intersection point, the profit generated from sales has reached a level where it can fully cover the principal and interest owed on the loan. This indicates that the business has generated enough funds to repay the loan in its entirety.
Part C:
As the principal (P) is increased while keeping the interest rate (r) and 12∙J(t) constant, the relationship between the two curves changes. Specifically, the intersection point between the curves shifts to the right on the graph.
This change in the relationship between the curves signifies that the business needs a higher level of profit to cover the increased loan amount. It suggests that the business has taken on a larger loan, which requires a higher profit to repay.
This situation is considered dangerous for the financial health of the business because it increases the risk of not generating sufficient profit to repay the loan. If the business fails to generate enough profit to cover the loan payments, it may lead to financial instability and potential default on the loan.
To mitigate such risks, banks put safeguards in place to prevent businesses from taking on excessive debt. These safeguards include conducting thorough evaluations of the business's financial health, setting limits on loan amounts based on the business's income and creditworthiness, and assessing the repayment capacity of the borrower. These measures aim to minimize the risk of defaults and protect both the borrower and the lender.

A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 82 m long and 53m wide. What is the length of a training track running around the field? (Use the value 3.14 and do not round your answer. Be sure to include the correct unit in your answer.)
Answer:
436.42 m
Step-by-step explanation:
We are to determine the perimeter of the field
perimeter = perimeter of rectangle + perimeter of the two semicircles
Perimeter of a rectangle = 2 x (length + breadth)
2 x (82 + 53) = 270m
Perimeter of a semicircle = 1/2πD
perimeter of the 2 semicircles = 2 x (1/2 x 3.14 x 53) = 166.42
Perimeter = 270 + 166.42 = 436.42 m

Assuming you meant 3/12, 1/3 and 1/2. The answer would be 5\(\frac{1}{4\\}\).
Answer:
\(288\frac{0}{13}\)
Solution :We can use the proportional method in this question
This case is a direct proportion
What is Direct Proportion?Direct proportion is a type of proportionality relationship. For direct proportion, as one value increases, so does the other value and conversely, as one value decreases, so does the other value. The symbol ∝ represents a proportional relationship.
We put the variable as x that represents the hour
We put it into a fractional form
\(\frac{312}{13} = \frac{x}{12}\)
Cross Multiplying
\(312X12 = 13x\)
\(3744 = 13x\)
\(\frac{3744}{13} = x\)
\(288\frac{0}{13} = x\)
a student claimed that the function shown in the table is exponential. do you agree or disagree? explain
The correct statement that F: "I agree. The ratios of consecutive x-values are constant, and the y-values are increasing at a constant rate."
To determine whether the function shown in the table is exponential, we need to analyze the relationship between the x-values and y-values.
The table shows x-values that are increasing by a power of 2 (1, 2, 4, 8, 16, 32, 64) and y-values that are increasing by a constant rate of 1 (0, 1, 2, 3, 4, 5, 6).
The constant ratio between consecutive x-values indicates exponential growth or decay.
In this case, the function is growing exponentially because the y-values are increasing at a constant rate.
Based on this information, we can conclude that the function is exponential.
Therefore, we agree with statement F: "I agree. The ratios of consecutive x-values are constant, and the y-values are increasing at a constant rate."
The other statements are incorrect because they do not accurately describe the relationship between the x-values and y-values in an exponential function.

The product of two numbers is 126 . The smaller number is 5 less than the larger number. Which of the following equations can be used to solve for the larger number?
Answer:
Step-by-step explanation:
45
What is (x³-8x² + 6x +41) ÷ (x-4)
Step 1: Write the dividend and divisor:
\(\sf\:\frac{{x^3 - 8x^2 + 6x + 41}}{{x - 4}} \\ \)
Step 2: Divide the first term of the dividend by the first term of the divisor:
\(\sf\:\frac{{x^3}}{{x}} = x^2 \\ \)
Step 3: Multiply the divisor (x - 4) by the result (x^2):
\(\sf\:(x - 4) \cdot (x^2) = x^3 - 4x^2 \\ \)
Step 4: Subtract the result from the original dividend:
\(\sf\:(x^3 - 8x^2 + 6x + 41) - (x^3 - 4x^2) = -4x^2 + 6x + 41 \\ \)
Step 5: Bring down the next term from the dividend:
\(\sf\:\frac{{-4x^2 + 6x + 41}}{{x - 4}} \\ \)
Step 6: Repeat steps 2-5 with the new dividend:
\(\sf\:\frac{{-4x^2}}{{x}} = -4x \\ \)
\(\sf\:(x - 4) \cdot (-4x) = -4x^2 + 16x \\ \)
\(\sf\:(-4x^2 + 6x + 41) - (-4x^2 + 16x) = -10x + 41 \\ \)
Step 7: Bring down the next term from the dividend:
\(\sf\:\frac{{-10x + 41}}{{x - 4}} \\ \)
Step 8: Repeat steps 2-5 with the new dividend:
\(\sf\:\frac{{-10x}}{{x}} = -10 \\ \)
\(\sf\:(x - 4) \cdot (-10) = -10x + 40 \\ \)
\(\sf\:(-10x + 41) - (-10x + 40) = 1 \\ \)
Step 9: There are no more terms to bring down, so the division is complete.
Step 10: Write the final result:
The quotient is \(\sf\:x^2 - 4x - 10\\\) and the remainder is 1.
Therefore, the division of \(\sf\:(x^3 - 8x^2 + 6x + 41) by (x - 4) \\\) is:
\(\sf\:(x^3 - 8x^2 + 6x + 41) ÷ (x - 4) \\ \) \(\sf\:= x^2 - 4x - 10 + \frac{{1}}{{x - 4}} \\ \)
