The equation of the line is (y - 1/12) = -4/3(x - 7/5).

What is the slope of a line?

A line's slope in mathematics is defined as the ratio of the change in the y coordinates to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are represented by y and x, respectively.

Consequently, the formula for the change in the y-coordinate with respect to the change in the x-coordinate is

m = y/x = y/x = change in y/change in x

where "m" represents a line's slope.

Additionally, the slope of the line can be depicted by

tan θ = Δy/Δx

So, the slope of a line is tan.

The given equation of a line is:

3x-4y=7

-4y = -3x + 7

y = 3/4 x - 7/4

The slope of the line is 3/4.

The slope of the line perpendicular to the given line is - 1/m = - 4/3

The point-slope of a line is y - y₁ = m(x - x₁).

The given point is (7/5,1/12)

Step-by-step explanation:

               In the photo, the quadrilateral is divided into two triangles, both having a base length of 4 feet and a height of 3 feet. Therefore, we can find the area of the entire quadrilateral by adding the areas of the two triangles together. Since the triangles have a base length of 4 feet and a height of 3 feet, their individual areas will be [tex]4*3*\frac{1}{2} =12*\frac{1}{2} = 6[/tex] square feet. As there are two triangles, we need to multiply the area of one triangle by 2 to get the total area of the quadrilateral, which would be [tex]6 * 2=12[/tex] square feet.

6,000 grams is equivalent to 6 kilograms.

The problem is solved by converting the given dimensions from grams to kilograms. The conversion is from a smaller metric unit to a larger metric unit.

A kilogram is a larger unit of measurement for mass or weight compared to a gram.

The prefix kilo in kilogram means 1000, so one kilogram is equal to 1000 grams.

Therefore, to convert from grams to kilograms, you simply divide the number of grams by 1000.

In this case, 6,000 grams divided by 1000 equals 6 kilograms.

Answer: The future value of an annuity due with a monthly payment of $300 at 6% interest compounded monthly for 10 years can be calculated using the formula:

FV = PMT * ( ( (1 + r)^n - 1) / r) * (1 + r)

where PMT = $300, r = 6%/12 = 0.05, and n = 10 years * 12 months/year = 120 months.

Substituting these values into the formula, we get:

FV = $300 * ( ( (1 + 0.05)^120 - 1) / 0.05) * (1 + 0.05)

FV = $300 * ( ( 1.05^120 - 1) / 0.05) * 1.05

FV = $300 * ( ( 2.704813829421526 - 1) / 0.05) * 1.05

FV = $300 * ( 1.704813829421526 / 0.05) * 1.05

FV = $300 * 34.09627658843153 * 1.05

FV = $52,113.63

Therefore, the future value of the annuity due is $52,113.63.

Step-by-step explanation:

The variance of the given frequency distribution is 60.92, and the standard deviation is option (b) 7.80.

To calculate the variance of a frequency distribution, we need to first find the mean or average of the data. The formula for calculating the mean is as follows:

mean (μ) = Σfx / Σf

where Σfx represents the sum of the products of each value and its corresponding frequency, and Σf is the sum of all the frequencies.

Using the given data, we can calculate the mean as follows:

μ = (43 + 85 + 119 + 175 + 204 + 243 + 32*1) / (3+5+9+5+4+3+1)

μ = 13.5

Next, we need to calculate the deviation of each data point from the mean. To do this, we subtract the mean from each value and square the result. The formula for this is:

(x - μ)²

Using this formula, we get the following deviations for each data point:

(4 - 13.5)² = 81.00

(8 - 13.5)² = 30.25

(11 - 13.5)² = 6.25

(17 - 13.5)² = 12.25

(20 - 13.5)² = 42.25

(24 - 13.5)² = 110.25

(32 - 13.5)² = 333.22

Next, we need to multiply each deviation by its corresponding frequency, and then sum up the results. The formula for this is:

Σf(x - μ)²

Using the above deviations and frequencies, we can calculate the sum of squares as follows:

Σf(x - μ)² = 381.00 + 530.25 + 96.25 + 512.25 + 442.25 + 3110.25 + 1 x 333.22

Σf(x - μ)² = 1827.48

Finally, we can calculate the variance by dividing the sum of squares by the total number of observations (Σf). The formula for variance is:

σ² = Σf(x - μ)² / Σf

Using the above values, we can calculate the variance as follows:

σ² = 1827.48 / 30

σ² = 60.92

The standard deviation is the square root of the variance. Therefore:

σ = √(60.92)

σ = 7.80

Therefore, the correction option is (b).

If the quotient of two functions f(x) and g(x) is a constant, then their derivatives are proportional to each other.

A function is an expression that shows the relationship between the independent variable and the dependent variable.  A function is usually denoted by letters such as f, g, etc.

If the quotient of two functions f(x) and g(x) is a constant k, meaning f(x)/g(x) = k for all x, then it follows that:

f(x) = k.g(x)

Taking the derivative of both sides with respect to x, we get:

f'(x) = k.g'(x) + g(x).d(k)/dx

Since the constant k is a constant and not a function of x, its derivative with respect to x is zero, so we can simplify the equation to:

f'(x) = k.g'(x)

Thus, we can see that if the quotient of two functions f(x) and g(x) is a constant, then their derivatives are proportional to each other, with the constant of proportionality equal to k.

The measure of angle R from the triangle PQR is 15.31°.

In trigonometry, the law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles.

The formula for the cosine rule is c=√(a²+b²-2ab cosC)

In the given triangle PQR, PQ=9 units, PR=12 units and RQ=20 units

PQ²=PR²+RQ² -2×12×20cosR

9²=12²+20² -2×12×20cosR

The number of monthly payments required to pay off the loan of $128,000 at 4% interest is 232.48 which is equivalent to approximately 232 payments.

To determine the number of monthly payments required to pay off a loan, you can use the formula for loan amortization: n = (-log(1 - B/A * r)) / log(1 + r)

Where: n = number of monthly payments, A = loan amount ($128,000), B = monthly payment ($611.09), r = monthly interest rate (4% / 12 months = 0.0033)

The number of monthly payments for the loan is plugged and computed as:

n = (-log(1 - $128,000/$611.09 * 0.0033)) / log(1 + 0.0033)

n = (-log(1 - 0.0208)) / log(1.0033)

n = (-log(0.9792)) / log(1.0033)

n = 21.8068 / 0.093984

Answer:

y=-2/3x-0.5

Step-by-step explanation:

y=mx+b is the equation for slopes so I used it and all I needed to find was the y-intercept, which is -0.5

Answer: The equation of the line passing through the points (1, -1, 2) and (0, 2, -3) is:       y = 3x - 4.

Step-by-step explanation:

To find the equation of a line passing through two points, we can use the point-slope form of a line. The point-slope form of a line is given by:

y - y1 = m(x - x1)

where m is the slope of the line, (x1, y1) is a point on the line, and (x, y) are the coordinates of any other point on the line.

Step 1: Find the slope of the line (m)

The slope of the line can be found using the two points:

m = (y2 - y1) / (x2 - x1)

Plug in the values of x1, x2, y1, and y2 from the two given points:

m = (2 - (-1)) / (0 - 1) = 3

Step 2: Write the equation using the point-slope form

Use the point-slope form and the slope from step 1, and one of the given points:

y - (-1) = 3(x - 1)

Step 3: Simplify the equation

y + 1 = 3x - 3

Step 4: Solve for y

y = 3x - 4

So, the equation of the line passing through the points (1, -1, 2) and (0, 2, -3) is y = 3x - 4.
