Answer:

Step-by-step explanation:

Old monthly payment = $966

New monthly payment = $605.10

Percent increase (to nearest tenth) = -37.3%

Given that,

Jim Tree bought a home with a 10% adjustable rate mortgage for 20 years.

He paid $9.66 monthly per thousand on his original loan.

At the end of 2 years, he owes the bank $55,000.

Interest rates have risen to 12%, and the bank will not renew the mortgage at this rate.

Jim can either pay the bank $55,000 or renew the mortgage at the higher interest rate.

Jim decides to renew and will now pay $11.02 monthly per thousand on his loan.

For comparison purposes, the small amount of principal that has been paid during the 2 years can be ignored.

Based on the information provided, Jim's old monthly payment can be calculated as follows:

Calculate Jim's original loan amount. We know that he paid $9.66 monthly per thousand on his original loan,

So if we divide his monthly payment by 1000,

We get his monthly interest rate:

$9.66 ÷ 1000 = 0.00966

Use the loan formula to calculate Jim's original loan amount:

Loan amount = Payment amount ÷ (Interest rate x (1 + Interest rate[tex])^N[/tex]- 1)

Where N is the number of payment.

Using this formula, and plugging in Jim's numbers, we get:

Loan amount = $9.66 ÷ (0.00966 x [tex](1 + 0.00966)^{240}[/tex] - 1)

                      = $100,000

Now that we know Jim's original loan amount, we can calculate his old monthly payment:

Old monthly payment = Loan amount x Payment amount per thousand

                                    = $100,000 x $9.66

                                    = $966

Therefore, Jim's old monthly payment was $966.

To calculate the new monthly payment and the percent increase,

We can follow these steps:

First, we need to calculate Jim's new loan amount.

We know that he owes the bank $55,000 after 2 years,

So we can use this amount as his new loan amount:

New loan amount = $55,000

Calculate Jim's new monthly interest rate.

We know that the interest rate has increased from 10% to 12%,

So we can calculate the new monthly interest rate as follows:

New monthly interest rate = 12% ÷ 12

                                            = 0.01

Use the loan formula again to calculate Jim's new monthly payment:

New monthly payment = Loan amount x Payment amount per thousand

                                      = $55,000 x $11.02

                                      = $605.10

Therefore, Jim's new monthly payment is $605.10.

To calculate the percent increase,

we can use the following formula:

Percent increase = ((New value - Old value) ÷ Old value) x 100%

Plugging in Jim's numbers, we get:

Percent increase = ((605.10 - 966) ÷ 966) x 100% = -37.3%

Therefore, the percent increase (to the nearest tenth) is -37.3%.

However, note that this is a negative value, which means that Jim's new monthly payment is actually lower than his old monthly payment.

This is likely due to the fact that the loan amount has decreased significantly since Jim has already paid off a portion of the loan during the first 2 years.

Final Answer:

Old monthly payment = $531.30
New monthly payment = $605.10
Percent increase in monthly payment (to the nearest tenth) = 13.9%

Explanation:

Let's calculate each part step by step.
Firstly, we will calculate the old monthly payment. Jim was paying at a rate of $9.66 monthly per thousand dollars of the original loan. We'll first determine how many thousands of dollars Jim owed at the beginning:

1. Old Monthly Payment:
Since he owes $55,000 at the end of 2 years and hasn't paid much towards the principal, we assume that the original loan amount was approximately $55,000.

Now, if he paid $9.66 per thousand dollars of the loan, we will calculate the monthly payment with the following steps:
- Divide the loan amount by 1,000 to find out how many "units" of $9.66 he would have to pay.
- Multiply the number of units by $9.66 to find the monthly payment.

Doing the calculations:
[tex]\( \frac{55,000}{1,000} = 55 \) units. \\\\\( 55 \text{ units} \times $9.66 = 55 \times 9.66 = $531.30 \).[/tex]
So, the old monthly payment was $531.30.

2. New Monthly Payment:
Now that the interest rate has increased to 12%, Jim will be paying at a rate of $11.02 monthly per thousand dollars.

Using the same method as above:
- Divide the loan amount by 1,000 to get the number of units.
- Multiply the number of units by $11.02 to find the new monthly payment.

Calculations:
[tex]\( \frac{55,000}{1,000} = 55 \) units.\\\\\( 55 \text{ units} \times $11.02 = 55 \times 11.02 = $605.10 \).[/tex]
So, the new monthly payment is $605.10.

3. Percent Increase in Monthly Payment:
To find the percent increase, we'll use the formula:

[tex]\[ \text{Percent Increase} = \left( \frac{\text{New Payment} - \text{Old Payment}}{\text{Old Payment}} \right) \times 100 \][/tex]
Performing the calculation:
[tex]\[ \text{Percent Increase} = \left( \frac{605.10 - 531.30}{531.30} \right) \times 100 \\\\\[ \text{Percent Increase} = \left( \frac{73.80}{531.30} \right) \times 100 \\\\\[ \text{Percent Increase} = 0.1388 \times 100 \\\\\[ \text{Percent Increase} = 13.88\% \][/tex]

To find the nearest tenth, we'll round the percent increase to one decimal place:
13.88% rounded to the nearest tenth is 13.9%.

Now, we can write down the final answers:
Old monthly payment = $531.30
New monthly payment = $605.10
Percent increase in monthly payment (to the nearest tenth) = 13.9%

4x2 - 25b2

We can solve it by the squares so

(2x - 5b) (2x + 5b)

2) x2 - 81

The same case is here so

(x - 9) (x + 9)

The factorization of the trinomial are;

a. 4x² - 25b² = (2x + 5b)(2x - 5b)

b. x² - 81 = (x + 9)(x - 9)

To factor the trinomial 4x² - 25b², we can use the difference of squares formula, which states that a² - b² can be factored as (a + b)(a - b).

Applying this formula to 4x² - 25b², we have:

4x² - 25b² = (2x)² - (5b)²

Now, we can rewrite the trinomial as a difference of squares:

4x² - 25b² = (2x + 5b)(2x - 5b)

Therefore, the trinomial 4x² - 25b² can be factored as (2x + 5b)(2x - 5b).

To factor the trinomial x^2 - 81, we can use the difference of squares formula once again:

x² - 81 = x² - 9²

This can be written as a difference of squares:

x² - 81 = (x + 9)(x - 9)

Thus, the trinomial x² - 81 can be factored as (x + 9)(x - 9).

Step-by-step explanation:

To find the number of minutes it will take for the stew to cool to a temperature of 30°C, solve the given nonlinear equation or graph it to find the intersection point.

The given function that models the relationship between the elapsed time, m, in minutes, and the temperature of the stew, T(m), is:

T(m) = 20 + 50 - 10^(-0.0477m)

To find the number of minutes it will take for the stew to cool to a temperature of 30°C, we need to solve the equation:

30 = 20 + 50 - 10^(-0.0477m)

By isolating the unknown variable, m, we can solve for it using logarithms or graphing. However, since the equation is nonlinear, graphing is a more intuitive approach. Graph the equation and find the x-coordinate at which the graph intersects with the y-coordinate 30. This value of m will give you the number of minutes it will take for the stew to cool to 30°C.

It's impossible to determine the accurate function h(w) that approximates the height of the sunflowers after w weeks from the question alone. This would typically involve evaluating a scatter plot and applying linear regression to find the best fitting function. The approximating function would be understood as the one that best matches the given options, minimizing the distance between the data points and the line.

The function that approximates the height of the sunflowers after w weeks (h(w)) cannot be determined directly from the question as it depends on the data present in the scatter plot that was mentioned. Given a scatter plot, we would aim to find a function that best approximates the trend or pattern seen in the plot.

It's an instance of linear regression, a statistical method used to model the relationship between a dependent variable (in this case, height of the sunflowers) and one or more independent variables (in this case, number of weeks). Assuming a linear relationship between weeks and the height of the sunflowers, we want to fit a linear equation (like the given options) that represents this correlation, minimizing the distance between the data points and the line.

Final answer:

The average speed of the canoe is 1.5 mph.

Explanation:

To find the average speed of the canoe, we need to calculate the time it takes for the canoe to go both upstream and downstream. Let's start with the time it takes to go upstream:

Distance = 3 miles
Speed of canoe = Speed in still water - Speed of current = 8 mph - 1 mph = 7 mph

Time = Distance / Speed = 3 miles / 7 mph = 0.429 hours

Now, let's calculate the time it takes to go downstream:

Distance = 3 miles
Speed of canoe = Speed in still water + Speed of current = 8 mph + 1 mph = 9 mph

Time = Distance / Speed = 3 miles / 9 mph = 0.333 hours

Finally, we can find the average speed of the canoe by dividing the total distance traveled (6 miles) by the total time taken (4 hours): average speed = total distance / total time = 6 miles / 4 hours = 1.5 mph.
