f(x)=-3x+4 ; translation 3 units down and a reflection in the y-axis.
what is g(x)
The translated and reflected function is:
g(x) = f(-x) - 3 = 3x + 1.
How to find the equation of the transformed function?Here we want to transform a function f(x)= -3x + 4.
First, remember that a vertical translation is written as:
g(x) = f(x) + N
If N > 0, the translation is upwards.if N < 0, the translation is downwards.Then a translation of 3 units down is written as:
g(x) = f(x) - 3
Now we want to do a reflection across the y-axis, this just changes the sign of the variable, so we get:
g(x) = f(-x) - 3
Now we replace the actual function f(x) by -3x + 4, we will get:
g(x) = -3*(-x) - 3 + 4 = 3x + 1
g(x) = 3x + 1
We conclude that the transformed function is 3x + 1.

The probability that a car has two doors, given that it is red, is 0.6 . The probability that a car has two doors and is red is 0.2 . What is the probability that a car is red?
The probability that a car is red is 1/3
What is the probability that a car is red?The given parameters are
P(Car has two doors, given that it is red) = 0.6
P(car has two doors and is red) = 0.2
The probability that a car is red is
P(Red) = P(car has two doors and is red)/P(Car has two doors, given that it is red)
This gives
p(Red) = 0.2/0.6

Find the sum of each finite arithmetic series. 7+14+21+ . . . . . . +105
The sum of the given finite arithmetic series 7+14+21+ . . . . . . +105 is S(5) = 840
The formula for the nth term in an arithmetic series is given by:
a(n) = a(1) + (n-1) . d
Where:
a(1) = the first term
d = the common difference = a(n) - a(n-1)
The given arithmetic series:
7+14+21+ . . . . . . +105
We can infer that:
a(1) = 7
d = 14 - 7 = 7
Find n that lead to a(n) = 105 by substituting a(1) = 7 and d = 7 into the formula:
a(n) = a(1) + (n-1) . d
105 = 7 + (n-1) . 7
105 = 7n
n = 15
Use the sum formula for n = 15.
S(n) = n/2 [a(1) + a(n)]
S(15) = 15/2 (7 + 105)
S(15) = 15 . 56 = 840

If DA = 7.4 centimeters, what is EF ?
If DA = 7.4 centimeters, then the radius of the circle EF is 3.7 inches.
What is meant by the radius of a circle?A radius of a circle or sphere is any of the line segments from its center to its perimeter in classical geometry, and in more modern usage, it is also their length. The name is derived from the Latin radius, which means both ray and spoke of a chariot wheel.
The radius of a circle is the distance between the circle's center and any point on its circumference. It is usually represented by the letters 'R' or 'r'. This number is significant in almost all circle-related formulas. A circle's area and circumference are also measured in terms of radius.
Here, DA is a diameter and EF is the radius.
Radius of a circle = 1/2 diameter
Where, d = 7.4
Radius of a circle, r = 1/2 d
Radius of a circle = 1/2(7.4)
Radius of a circle = 3.7
Therefore, the radius of the circle is 3.7 inches.

A student walked 100 meters north, then 100 meters west. How many more meters did the student walk compared to their total displacement from their starting point?.
The student walked 58.58 meters more than the total displacement from the starting point.
Given that a student walked 100 meters north, then 100 meters west.
We are required to find the number of meters, the student travelled more as compared to the total displacement from the starting point.
We have to find the distance from the starting point to ending point. We have to apply pythagoras theorem to find that distance.
Pythagoras theorem basically says that the square of hypotenuse of right angled triangle is equal to the sum of squares of base and perpendicular.
[tex]H^{2} =P^{2} +B^{2}[/tex]
In our case P is 100 meters and B is 100 meters and we have to find H from the formula given above.
[tex]H^{2} =100^{2} +100^{2}[/tex]
H=[tex]\sqrt{10000+10000}[/tex]
H=[tex]\sqrt{20000}[/tex]
H=141.42 meters
Difference=100+100-141.42
=200-141.42
=58.58 meters
Hence the student walked 58.58 meters more than the total displacement from the starting point.

Step-by-step explanation:
b) Figure 1 is 2² = 4 (which is also 2x2=4 or if you count all the squares = 4)
Figure 2 is 3² = 9 (which is also 3x3=9 or if you count all the squares = 9 )
Figure 3 is 4² = 16 (which is also 4x4=16 or if you count all the squares = 16 )
Figure 4 is 5² =25(which is also 5x5=25 or if you count all the squares = 25)
Figure 5 is 6² = 36(which is also 6x6=36 or if you count all the squares =36)
c) Figure 1 add squares in a horizontal row which is your x-coordinate (2)
then add squares in a vertical row which is your y-coordinate (2)
so (x,y) = (2,2). Graph those points. Do the same for each and your line is a diagonal straight line traveling diagonally upward equally.

When Rachel stands next to her cousin, Rachel's shadow is 2 feet long and her cousin's shadow is 1 foot long. If Rachel is 5 feet 6 inches tall, how tall is her cousin?
When measuring height, it is necessary to represent both the vertical position and the separation between the minimum and maximum place or location. Rachel is 5 feet 6 inches tall, the tall is her cousin exists 2 feet 9 inches.
What is meant by tall?In math, tall can be defined as the vertical distance from the top to the base of the object. Tall is the distance between an object's highest and lowest points.
The measurement of an object's height from the base to the top is known as tall. It is sometimes referred to as altitude in geometry. The vertical distance between the lowest and highest point is measured. In coordinate geometry, it is often the measurement along the y-axis of an object.
Rachel/Cousin = Rachel's shadow / Cousin's shadow
5 feet 6/x = 2/1
simplifying the above equation, we get
5ft 6 = 2x
x = 5ft 6/2
x = 66in/2
x = 33 in
x = 2ft 9inch
Therefore, the value of x = 2ft 9inch.

Directrixd = y = 1.75
We define what a parabola is
What is a parabola?The parabola is a geometric shape that is formed from the intersection of a vertical plane in a cone.
The canonical equation of a parabola is given by
(x - h)² = 4p(y - k)
The parabola is a quadratic function, it is composed of a vertex, or inflection point, a focus and a directrix.
The parabola equation is:
y = x² + 8x + 18
y - 18 + 16 = x² + 8x + 16
y - 2 = x² + 2(4x) + 4²
y - 2 = (x + 4)²
This means that the vertex of this parabola is
v = (h, k)
v = (-4,2)
4p = 1p = 1/4f = (-4, 2 + 1/4)
