[tex]f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}[/tex]
[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]

[tex]f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}[/tex]
Given function:
[tex]r(x) = |x - 2| - 1[/tex]
The parent function of the given function is: [tex]f(x) = |x|[/tex]
Translated 2 units to the right: [tex]f(x-2)=|x-2|[/tex]
Translated 1 unit down: [tex]f(x-2)-1=|x-2|-1[/tex]
Graph of Modulus function
Line y = x where x ≥ 0
Line y = -x where x ≤ 0
Vertex at (0, 0)
Therefore, the graph of the given function is the graph of the modulus function translated 2 units to the right and 1 unit down. So, its vertex is at (2, -1).

Keiko+has+a+health+insurance+premium+of+$3298+annually. +if+her+employer+pays+90%+of+the+premium,+how+much+does+she+pay+annually?
Answer: $329.8
[tex]3298-(\frac{90}{100} *3298)\\= 3298 - 2968.2\\= 329.8[/tex]
The amount Keiko pays annually is $329.8
To answer the question, we need to know the amount Keiko pays annually
How to calculate how much Keiko pays annually.Since Keiko health insurance premium annually is $3298 and if his employer pays 90% of the premium, we want to know how much Keiko pays.
Since the employer pays 90% of the premium, the employer pays x = 90% of $3298
= 0.9 × 3298
= $2968.2
So, the amount Keiko pays annually is y = premium - amount employer pays, x
= $3298 - $2968.2
= $329.8
So, the amount Keiko pays annually is $329.8

none of the above
Answer:
a) 19 cm
Step-by-step explanation:
Area of a parallelogram: b • h
Given values:
A = 228 cm²b = ? cmh = 12 cmSubstitute these values into the formula:
⇒ A = b • h
⇒ 228 = b • 12 [multiply]
⇒ 228 = 12b [divide both sides by 12]
⇒ 228 ÷ 12 = 12b ÷ 12
⇒ 19 = b
Therefore, the base of the parallelogram is 19 cm.

tan205
Answer:
cos65 = sin25 = p
tan205 = tan25 = p/√(1-√p)
Step-by-step explanation:
trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (cosec)
some Trigonometric identities used in the question:
cos(90-θ) = sinθsin²θ + cos²θ = 1tan(π±θ) = tanθtanθ = sinθ/cosθin the question it is given,
sin25 = p
using above mentioned identity:-
cos 65 = cos(90-25) = sin25 = p
hence value of cos65 is p.
for, tan205 we have to first find the cos25
so to find cos25 we use above mentioned identity,
cos²25 + sin²25 = 1
cos²25 + √p = 1
cos²25 = 1-√p
cos25 = √(1-√p)
now to find out tan205 use third identity mentioned above,
tan205 = tan(π+25) = tan25
tan25 = sin25/cos25
tan25 = p/√(1-√p)

%
Answer:
fraction:4/10 or 2/5
decimal: 0.4
percent: 40%
Step-by-step explanation:
The rectangle is divided into 10 parts, this is a total number that goes on the bottom of a fraction. 4 parts are shaded, that number goes on the top of the fraction.
4/10 is shown in the image. But 4/10 can be reduced. You should always simplify a fraction when it is possible.
4/10 = 2/5
As for the decimal, 4/10 spoken, "four tenths" tells you the decimal 0.4 (we all say "point four", but this is properly called "four-tenths" also) You can divide, because a fraction bar is a division symbol:
4÷10 OR 2÷5 and you will get the decimal 0.4
To change the decimal to a percent, multiply by 100.
0.4 × 100 is 40
0.4 is 40%

Equation of a line
A line is the shortest distance between two points. The equation of a line in slope-intercept form is y = mx + b while as a standard notation is Ax+By = C
Given the coordinate points (-3, -7) and (5, 6)
Determine the slope
Slope = 6-(-7)/5-(-3)
Slope = 13/8
For the y-intercept
6 = 13/8(5) + b
6 = 65/8 + b
b = 6 - 65/8
b = -17/8
The equation in slope-intercept form is y = 13/8x -17/8
Write in standard form
Recall y = 13/8x - 17/8
Multiply through by 8
8y = 13x - 17
-13x + 8y = -17
13x -8y = 17

Answer:
c = 5√5
Step-by-step explanation:
When we have a right triangle, there is a property about its measurements that is always true, and its called the "Pythagorean Theorem"
First, let's understand the basic terms we use to describe the sides of a triangle:
we can call one leg "a", the other leg "b" and the slanted side "c"
("c" is also called the hypotenuse--and it's always opposite the 90-degree angle)
the pythagorean theorem:
a² + b² = c²
here, our "a" is 5, our "b" is 10 {and we don't know what c is}
let's try plugging these values into our formula:
a² + b² = c²
5² + 10² = c²
25 + 100 = c²
125 = c²
now, we know what c² is--but we want to know c,
so we must take the square root of both sides
√125 = √c²
√125 = c
now, while √125 is our answer, we can simplify further!
this is because 125 can be made up of 5 · 25
so, [tex]\sqrt{125} = \sqrt{5*25}[/tex]
and
[tex]\sqrt{5*25}=\sqrt{5}*\sqrt{25}[/tex]
we can take out the square root of 25 (5):
[tex]=\sqrt{5}*5[/tex]
we write this as such: [tex]5\sqrt{5}[/tex]
so, in simplest radical form, c = 5√5
(√125)
