Nathan's monthly payment will be Php 25,496.45.

To calculate the monthly payment for Nathan's car loan, we can use the formula for the monthly payment on a loan with compound interest:

Monthly Payment = (Loan Amount * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-Total Number of Payments))

Given:

Loan Amount (Principal) = Php 1,200,000.00

Interest Rate = 10% per year

Compounding Period = Monthly

Loan Term = 5 years (60 months)

First, we need to convert the annual interest rate to a monthly interest rate:

Monthly Interest Rate = (1 + Annual Interest Rate)^(1/Number of Compounding Periods) - 1

Monthly Interest Rate = (1 + 0.10)^(1/12) - 1

Monthly Interest Rate = 0.007974

Substituting the values into the formula:

Monthly Payment = (1,200,000 * 0.007974) / (1 - (1 + 0.007974)^(-60))

Monthly Payment = 25,496.45 (rounded to two decimal places)

Therefore, Nathan's monthly payment for the car loan will be Php 25,496.45.

Proportions are mathematical statements that show the equality of two ratios. To determine if a given pair of ratios form a proportion, we need to check if the ratios are equivalent.

A proportion is formed when two ratios are equal. In other words, if we cross-multiply the fractions and the results are equal, then the fractions are in proportion.

Let's examine each option:

A. 25/10 = 5/2

To check if this is a proportion, we cross-multiply:

25 * 2 = 10 * 5

50 = 50

Since the cross-products are equal, this is a proportion.

B. 3/4 = 8/10

Cross-multiplying:

3 * 10 = 4 * 8

30 ≠ 32

The cross-products are not equal, so this is not a proportion.

C. 2/8 = 3/12

Cross-multiplying:

2 * 12 = 8 * 3

24 = 24

The cross-products are equal, so this is a proportion.

D. 3/4 = 15/20

Cross-multiplying:

3 * 20 = 4 * 15

60 = 60

The cross-products are equal, so this is a proportion.

Step-by-step explanation:

Answer:

Step-by-step explanation:

recall   the two formulas

y = mx - b            slope-intercept

y - y1 = m(x-x1)     point-slope

with these  we can get the equation .  we also need to find the slope  m

m =  y2-y1 / x2-x1

m = 3 - (-1) / 2-4

m = 3 + 1 / -2

m = 4 / -2

m = -2

now with the slope known,  plug in either point into the point-slope formula and work to the slope-intercept formula, I'll use (2,3)  as the point to plug in.

y - 3 = -2(x-2)

y - 3 = -2x +4

Complete Question:

Emily and Zach have two different polynomials to multiply: Polynomial product A: (4x2 – 4x)(x2 – 4) Polynomial product B: (x2 + x – 2)(4x2 – 8x) They are trying to determine if the products of the two polynomials are the same. But they disagree about how to solve this problem.

Answer:

\(A = B\)

Step-by-step explanation:

See comment for complete question

Given

\(A: (4x^2 - 4x)(x^2 - 4)\)

\(B: (x^2 + x - 2)(4x^2 - 8x)\)

Required

Determine how they can show if the products are the same or not

To do this, we simply factorize each polynomial

For, Polynomial A: We have:

\(A: (4x^2 - 4x)(x^2 - 4)\)

Factor out 4x

\(A: 4x(x - 1)(x^2 - 4)\)

Apply difference of two squares on x^2 - 4

\(A: 4x(x - 1)(x - 2)(x+2)\)

For, Polynomial B: We have:

\(B: (x^2 + x - 2)(4x^2 - 8x)\)

Expand x^2 + x - 2

\(B:(x^2 + 2x - x - 2)(4x^2- 8x)\)

Factorize:

\(B:(x(x + 2) -1(x + 2))(4x^2- 8x)\)

Factor out x + 2

\(B:(x -1) (x + 2)(4x^2- 8x)\)

Factor out 4x

\(B:(x -1) (x + 2)4x(x- 2)\)

Rearrange

\(B: 4x(x - 1)(x - 2)(x+2)\)

The simplified expressions are:

\(A: 4x(x - 1)(x - 2)(x+2)\) and  

\(B: 4x(x - 1)(x - 2)(x+2)\)

Hence, both polynomials are equal

\(A = B\)

As a result, the total distance traveled by Mary in her round trip is 3/2 mile + 3/2 mile = 6/2 mile = 3 mile

We can calculate the total distance traveled by a body with position function s (t) if it moves along a coordinate line without changing direction from t = a to t = b. If the body changes direction during the journey, we must integrate the body's speed |v (t)| to find the total distance traveled.

Therefore,

We know Mary spent only a third of the time coming from school as she did going because she traveled three times as fast coming from school as she did going to school (6 miles per hour versus 2 miles per hour). If x represents the time it took her to get to school, then x/3 represents the time it took her to return.

Knowing that the total trip took 1 hour, we have:

x + x/3 = 1

3x/3 + 1x/3 = 1

4x/3 = 1

x  = 3/4

So we know it took Mary 3/4 of an hour to get to school (and 1/4 of an hour to get home).

Remembering that distance = rate × time, Mary's commute to school was (2 miles per hour) × (3/4 of an hour) = 3/2 mile. Furthermore, because she returned via the same route, she must have traveled 3/2 of a mile.

As a result, the total distance traveled by Mary in her round trip is 3/2 mile + 3/2 mile = 6/2 mile = 3 mile.

To obtain the residuals from the fit in 8.4a and plot them against y and x, as well as prepare a normal plot, we need the specific details of the fit and the data used.

WE know that residuals represent the differences between the observed values and the predicted values from a statistical model or regression analysis.

Since the residuals against y and x can help identify patterns or trends in the data that may indicate issues with the model's fit.

A normal plot, known as a Q-Q plot, compares the distribution of the residuals to a theoretical normal distribution. If the residuals closely follow a straight line in the normal plot, the residuals are normally distributed, which is an assumption of many statistical models.

Interpreting these plots involves examining the patterns and deviations from expected behavior. If the residuals exhibit a consistent pattern, it might indicate that the model does not capture all the relevant information in the data.

Thus if the residuals appear randomly scattered around zero with no discernible pattern, it suggests that the model adequately explains the data. Deviations in the normal plot may indicate departures from the assumption of normality in the residuals, which could impact the reliability of statistical inferences.

the possible values of x are -18/7 and 10. However, since the length and width of a rectangle cannot be negative, the only valid solution is x = 10 and  the first rectangle has length 100 units and width 20 units, and the second rectangle has length 320 units and width 60 units. Their length to width ratios are both 5:1.

The length to width ratio of the first rectangle is \((x^2-12x+20)/(x+10),\)and the length to width ratio of the second rectangle is \((x^2+12x+20)/(5x+10).\)If both ratios are the same, then we can set them equal to each other and solve for x:

\((x^2-12x+20)/(x+10) = (x^2+12x+20)/(5x+10)\)

Multiplying both sides by (x+10)(5x+10) gives us:

\((x^2-12x+20)(5x+10) = (x^2+12x+20)(x+10)\)

Expanding both sides and simplifying gives us:

\(7x^2 - 2x - 180 = 0\)

We can factor the left-hand side to get:

(7x+18)(x-10) = 0

Therefore, the possible values of x are -18/7 and 10. However, since the length and width of a rectangle cannot be negative, the only valid solution is x = 10.
