The distance from point (x, y) to the line ax+by+c=0 is given by ...
d = |ax +by +c|/√(a²+b²)
In general for, the equation of the line is ...
y = x/3 - 4
i.e. x -3y -12 = 0
so the distance formula is ...
d = |x -y -12|/√(1² +(-3)²) = |x -y - 12|/√10
For the given point, the distance is ...
d = |-6 -4 -12|/√10
= 22/√10
d = 22/√10 . . . .

Answer:
1. 2430 feet
2. 1.8 m/s^2
Step-by-step explanation:
See the attached worksheet.
A time versus speed graph contains a small treasure of mathematical rewards. The area under the graph is equal to the distance travelled. The slope of the line segments represents acceleration.
For total distance: If we break the graph into three sections (2 triangles and a rectangle) we can calculate the areas for each. Each area is the distance travelled for that segment. As shown on the workseet, the total area is 2430 miles, the distance travelled by the train for this question.
The slope of the line in the first 10 seconds is 1.8 meters/sec^2, the acceleration of the train over that period.
3) a) Prove that the following functions are harmonic and find for each function its harmonic conjugate i 2e* cosy i) x² + 2x - 4² b) Prove: Ifuis harmonic conjugate of vin a domain v and is harmoni
a)
i) The function is not harmonic.
ii). The function is harmonic.
b) v is also harmonic in D
a) A function is harmonic if it satisfies the Laplace equation:
∂²u/∂x² + ∂²u/∂y² = 0
i) For the function u = x² + 2x - 4², we can take the partial derivatives with respect to x and y:
∂u/∂x = 2x + 2
∂u/∂y = 0
∂²u/∂x² = 2
∂²u/∂y² = 0
Plugging these into the Laplace equation, we get:
2 + 0 = 0
This is not true, so the function is not harmonic.
ii) For the function u = 2e* cos(y), we can take the partial derivatives with respect to x and y:
∂u/∂x = 0
∂u/∂y = -2e* sin(y)
∂²u/∂x² = 0
∂²u/∂y² = -2e* cos(y)
Plugging these into the Laplace equation, we get:
0 + (-2e* cos(y)) = 0
-2e* cos(y) = 0
This is true for all values of y, so the function is harmonic.
The harmonic conjugate of a function u(x,y) is a function v(x,y) such that f(z) = u(x,y) + i*v(x,y) is analytic. To find the harmonic conjugate of u = 2e* cos(y), we can use the Cauchy-Riemann equations:
∂u/∂x = ∂v/∂y
∂u/∂y = -∂v/∂x
Plugging in the partial derivatives of u, we get:
0 = ∂v/∂y
-2e* sin(y) = -∂v/∂x
Integrating both equations with respect to x and y, we get:
v = C₁
v = 2e* cos(y) + C₂
Setting these equal to each other and solving for v, we get:
v = 2e* cos(y) + C
So the harmonic conjugate of u = 2e* cos(y) is v = 2e* cos(y) + C, where C is a constant.
b) If u is the harmonic conjugate of v in a domain D, then f(z) = u(x,y) + i*v(x,y) is analytic in D. This means that f(z) satisfies the Cauchy-Riemann equations:
∂u/∂x = ∂v/∂y
∂u/∂y = -∂v/∂x
If we take the partial derivatives of these equations with respect to x and y, we get:
∂²u/∂x² = ∂²v/∂x∂y
∂²u/∂x∂y = -∂²v/∂x²
∂²u/∂y∂x = -∂²v/∂y²
∂²u/∂y² = ∂²v/∂y∂x
Adding the first and last equations, we get:
∂²u/∂x² + ∂²u/∂y² = ∂²v/∂x∂y + ∂²v/∂y∂x
Since the mixed partial derivatives are equal, this simplifies to:
∂²u/∂x² + ∂²u/∂y² = 0
So u is harmonic in D. Similarly, we can add the second and third equations to get:
∂²v/∂x² + ∂²v/∂y² = 0
So v is also harmonic in D. Therefore, if u is the harmonic conjugate of v in a domain D, then both u and v are harmonic in D.

How do we solve this?In the exponential sequence given by a, b, c, d, ..., where a and b are the first two numbers. We know that the third number is given by b * c/a, and the fourth number is given by c * d/b.
the third number = 100
the fourth number = 500,
So b * c/a = 100
c * d/b = 500
rearranging the first equation :
c = 100a/b

There are two solutions to the equation 1/(1 - x²) = -|3x - 2| + 5.
What is Equation?An equation is a statement that shows that two mathematical expressions are equal to each other. It typically consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, and exponents.
We can start by considering the case where the expression inside the absolute value is non-negative, i.e., 3x - 2 ≥ 0, which implies x ≥ 2/3. In this case, the equation becomes:
1/(1 - x²) = 3x - 2 + 5
1/(1 - x) = 3x + 3
Multiplying both sides by 1 - x², we get:
1 = (3x + 3)(1 - x²)
3x³ + x² - 3x - 2 = 0
This equation has one real root.
The root is approximately x = 0.727.
Next, we consider the case where the expression inside the absolute value is negative, i.e., 3x - 2 < 0, which implies x < 2/3. In this case, the equation becomes:
1/(1 - x²) = -(3x - 2) + 5
Simplifying this equation, we get:
1/(1 - x) = -3x + 3
1 = (-3x + 3)(1 - x²)
3x³ - x² - 3x + 2 = 0
This equation also has one real root, which we can find using the same methods as before. The root is approximately x = -0.727. \
Therefore, there are two solutions to the equation 1/(1 - x²) = -|3x - 2| + 5.

The probability that X is greater than 1 is less than or equal to 0.5, making the correct answer (C) 0.5.
Markov's inequality states that for a non-negative random variable X and a positive number a, the probability that X is greater than a is less than or equal to the expected value of X divided by a. In mathematical terms, this can be written as:
P(X > a) ≤ E(X) / a

What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
To describe the possible solution sets of the inequality ax + b < cx + d, we need to isolate the variable x on one side of the inequality and simplify.
ax + b < cx + d
ax - cx < d - b
x(a-c) < d - b
x < (d - b)/(a-c)

Other fractions could represent the part of the beads on the bracelet that will be green are : 1/3, 2/6, 3/9, 4/12.
What is fraction?A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.
here, we have,
The maximum number of beads the bracelet can have = 12 beads
The fraction of green beads in the bracelet = 1/3
⇒ 1 bead in every 3 bead is GREEN.
⇒The minimum number of total beads = Number of (green+ Other) bead = 2 + 1 = 3
Now, the possible number of total beads the bracelet can have is
3, 4, 5 , 6, 7, 8, 9 ,10, 11 and 12.
If there are total 3 beads, the fraction representing the green bead = 1/3
If there are total 6( =3 +3) beads, the fraction representing the green bead
= 1 green bead in first 3 beads + 1 green bead in next 3 beads
= 2 green beads in total 6 beads
= 2/6
If there are total 9( = 3 +3 +3) beads, the fraction representing the green bead = 3/9
If there are total 12( = 3 + 3 +3 +3) beads, the fraction representing the green bead = 4/12

Q has y-coordinate of -4 => the distance from origin to y-coordinate is 4 units, which is one leg of the right triangle
Pythagorean theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
c^2 = a^2 + b^2
with c = 5, a = 4
5^2 = 4^2 + b^2
b^2 = 25 - 16 = 9
b = √9 = 3
so Q has coordinates (3,-4)

Knowledge Check Question 13 Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator. 3.5cm:1.4cm
The ratio 3.5cm:1.4cm can be written as the fraction 5/2 in simplest form, with whole numbers in the numerator and denominator.
To write the ratio as a fraction in simplest form, we will follow the steps below:
Step 1: Write the ratio as a fraction. In this case, we have 3.5cm:1.4cm, which can be written as 3.5cm/1.4cm.
Step 2: Simplify the fraction by dividing both the numerator and denominator by the greatest common factor (GCF). In this case, the GCF of 3.5 and 1.4 is 0.7. So we will divide both the numerator and denominator by 0.7 to get:
(3.5cm/0.7) / (1.4cm/0.7) = 5/2
Step 3: Convert the fraction to simplest form with whole numbers in the numerator and denominator. In this case, we can multiply both the numerator and denominator by 10 to get:
(5*10)/(2*10) = 50/20
Step 4: Simplify the fraction by dividing both the numerator and denominator by the GCF. In this case, the GCF of 50 and 20 is 10. So we will divide both the numerator and denominator by 10 to get:
(50/10)/(20/10) = 5/2
Therefore, the ratio 3.5cm:1.4cm can be written as the fraction 5/2 in simplest form, with whole numbers in the numerator and denominator.

The estimated height of the child at delivery is represented by the y-intercept, which is 72.66.
What is an equation to model the relationship between the height, in centimeters, and the age, in years, of this child?We may use linear regression to construct an equation that represents the link between this child's height and age. The line of best fit for the supplied data is determined by linear regression, which can be written as:
Age (years) + b * m * Height (cm)
where m denotes the line's slope and b its y-intercept.
The equation that most closely matches the above data can be determined using a calculator or spreadsheet software as follows:
Age (years) + 72.66 Height (cm) = 6.087
Thus, the height of the youngster increases by roughly 6.087 centimetres for every year that their age rises. The estimated height of the infant at delivery is represented by the y-intercept, which is 72.66.
