The distance between the point (5,12) and the line y = 5x + 12 is 4.90 units

If a point P with the coordinates (x₁, y₁), and we need to know its distance from the line represented by ax + by + c = 0

Then the distance of a point from the line is given by the formula:

d = (ax₁ + by₁ + c) / √(a² + b²)

Given: the point (5,12) and the line y = 5x + 12. The line can be written as

5x-y+12 = 0. Thus:

x₁ = 5, y₁ = 12, a = 5, b = -1, c = 12. Substitute these into the formula:

d = (ax₁ + by₁ + c) / √(a² + b²)

d = (5×5 + (-1×12) + 12) / √(5² + (-1)²)

d = 25/√26 = 4.90 units

Therefore, the distance between the point and the line is 4.90 units. Option D is the answer

Answer:

x = 5

Step-by-step explanation:

We know that BD = 2x - 1 and BC + CD = BD.  Thus, we can set the sum of (x- 3) and 7 equal to 2x - 1 to find x:

BC + CD = BD

x - 3 + 7 = 2x - 1

x + 4 = 2x - 1

x + 5 = 2x

5 = x

Thus, x = 5

Checking the validity of our answer:

We can check that our answer is correct by plugging in 5 for x in x - 3 and 2x - 1 and checking that we get the same answer on both sides of the equation:

5 - 3 + 7 = 2(5) - 1

2 + 7 = 10 - 1

9 = 9

Thus, our answer is correct.

=(D-64)2

We move all terms to the left:

-((D-64)2)=0

We calculate terms in parentheses: -((D-64)2), so:

We multiply parentheses

2D-128

Back to the equation:

-(2D-128)

We get rid of parentheses

-2D+128=0

We move all terms containing D to the left, all other terms to the right

-2D=-128

D=-128/-2

The probability that an individual man's step length is less than 1.9 feet is approximately 0.1056 or 10.56% (rounded to 4 decimal places).

Probability is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Math to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution,

The standardized value, also known as the z-score, is given by:

\(Z = \dfrac{(\text{x} - \mu)}{\sigma}\)

Substituting the given values, we get:

\(Z = \dfrac{(1.9 - 2.4)}{0.4}\)

\(Z = -1.25\)

Now we need to find the probability that an individual man's step length is less than 1.9 feet, which is equivalent to finding the area under the standard normal distribution curve to the left of the z-score -1.25.

Using a standard normal distribution table or calculator, we can find that the area to the left of -1.25 is 0.1056.

Therefore, the probability that an individual man's step length is less than 1.9 feet is approximately 0.1056 or 10.56% (rounded to 4 decimal places).

We know that the cooking club made pies to sell, but we don't know how many pies the cooking club made. So, let the number of pies the cooking club made be x.

Now the cafeteria contributed 4 pies that were cut into 5 pieces and sold. So the cafeteria contributed

The cafeteria contributed 20 pieces.

Also we were told that a total of 60 pieces were sold. So what the club sold should be 60 pieces in total minus what the cafeteria sold.

So we have

The club sold 40 pieces.

Now remember that a pie is cut into 5 pieces, so this means that 40 pieces should make

Hence the club made 8 pies

Step-by-step explanation

If the given zeros are 4 and -2+√5, then the polynomial function of the least degree with integral coefficients that has these zeros can be obtained by using the fact that if a polynomial has a root at x=a, then it has a factor of (x-a).

Therefore, the polynomial function with these zeros can be written as:

(x - 4)(x - (-2+√5))(x - (-2-√5))

Expanding the factors using the difference of squares, we get:

(x - 4)((x + 2) - √5)((x + 2) + √5)

Simplifying the expression further, we get:

(x - 4)((x + 2)^2 - 5)

Expanding the square, we get:

(x - 4)(x^2 + 4x - 1)

Therefore, the polynomial function of the least degree with integral coefficients that has the zeros 4 and -2+√5 is:

f(x) = (x - 4)(x^2 + 4x - 1)

Expanding the factors, we get:

f(x) = x^3 + 4x^2 - x - 16

Answer: 7

Step-by-step explanation: -4(6 - b) = 4

The value of p when q is 2 is 1

Inverse variation is the relationships between variables that are represented in the form of y = k/x, where x and y are two variables and k is the constant value.

This means that has x increases y will decrease and vice versa.

If p is inversely proportional to q , then p = kq

when p = 2, q = 4

2 = k4

k = 2/4

k = 1/2

When q = 2

p = 1/2 × 2

p = 1

Therefore the value of p is 1

By answering the presented question, we may conclude that As a result, the slope of \(y_3\) = -4(x - 5) is -4.

The slope of a line indicates how steep it is. The term "gradient overflow" refers to a mathematical equation for the gradient (the change in y divided by the change in x).

The slope is defined as the ratio of the vertical change (rise) between two places to the horizontal change (run). The slope-intercept form of an equation is used to express a straight line's equation, which is written as y = mx + b.

The y-intercept is found where the slope of the line is m, b is b, and (0, b). For example, the slope and y-intercept of the equation y = 3x - 7 (0, 7). The slope of the line is m. b is b at the y-intercept, and (0, b).

The above equation is in point-slope form: y - \(y_1\)= m(x - \(x_1\)), where (\(x_1\), \(y_1\)) is a point on the line and m is the slope.

We can see by comparing the provided equation to the point-slope form that \(x_{1} ,y_1\)) = (5, 3) and m = -4.

As a result, the slope of \(y_3\) = -4(x - 5) is -4.

Answer:

z = 2√2

w = 4√2

x = 2√6

Step-by-step explanation:

ADC is a right angled triangle at D.

Then

z = 4 × sin(45)

  = 4 × sin(45)

  \(=4 \times \frac{\sqrt{2} }{2}\)

  \(=2\sqrt{2}\)

\(w = \frac{z}{\sin(30)}\)

   \(= \frac{2\sqrt{2} }{\frac{1}{2}}\)

    \(= 4\sqrt{2}\)

x = w × cos(30)

  = 4√2 × cos(30)

  \(= 4\sqrt{2} \times \frac{\sqrt{3}}{2}\)

  \(= 2 \sqrt{6}\)

The man still owes R87,726 in taxes.

To calculate the tax amount the man still owes, we need to determine his taxable income first.

Gross income: R500,000

Less: PAYE deductions (17% of gross income): R500,000 * 0.17 = R85,000

Taxable income: R500,000 - R85,000 = R415,000

Next, we can use the tax table information provided to calculate the tax owed based on the taxable income.

Tax owed: R93,135 + 36% of (taxable income - R393,200)

Tax owed: R93,135 + 0.36 * (R415,000 - R393,200)

Tax owed: R93,135 + 0.36 * R21,800

Tax owed: R93,135 + R7,848

Tax owed: R100,983

Finally, we subtract the rebate amount of R13,257 from the tax owed to find the amount the man still owes.

Tax owed - Rebate: R100,983 - R13,257 = R87,726

Therefore, the man still owes R87,726 in taxes.
