Answer:
-2b
Step-by-step explanation:
since
|x| = x if x>0
and
|x| = -x if x<0
then it is -2b
The given modulus function at (b < 0) is written as (f(b) = -2b) and this can be determined by using the properties of the modulus function.
Given :
Expression -- |2b| where b < 0
The following steps can be used in order to rewrite the given expression:
Step 1 - The generalized modulus function is given by:
f(x) = |x|
Step 2 - When x > 0 the above function becomes:
f(x) = x
Step 3 - When x < 0 the above function becomes:
f(x) = -x
Step 4 - So, the given expression is also a modulus function. The given modulus function at (b < 0) is written as:
f(b) = -2b

In this problem, we will look into the geometric design of the three-petal motif seen in a medieval rose window shown in the picture.
The three major arcs seen in the construction image 1 are congruent. The direct distance between E and J (Chord length EJ) is 193 cm and the depth of each arc (length of LK shown in construction image 2) is 147 cm.
what is the total area?
The total area of the three-petal motif is [tex]93937cm^2[/tex]
The three petal motif has the structure shown in the accompanying image. the dark gray area is the equilateral triangle. The light gray areas are the major segments of each of the circles.
The area of the three-petal motif, then, is the sum of the area of the equilateral triangle and the three major segments (all of which have the same area)
From the second image
Area of equilateral triangle = [tex]16129cm^2[/tex]
Area of each major segment = [tex]25936cm^2[/tex]
Therefore,
Area of three-petal motif = [tex]16129cm^2+3(25936cm^2)=93937cm^2[/tex]

At which values of x does the function F(x) have a vertical asymptote? Check all that apply.
You get vertical asymptotes because the x-value causes you to try to divide by 0.
If you look at the denominator, the x-values of 0, 1, and -5 all will make the denominator equal to 0, making the whole function explode.
You find these by solving 3x(x-1)(x+5)=0.
That's your answer: 0, 1, and -5

for an inverse variation, y=5 when x=9. The value of the constant of variation is
Answer:
45
Step-by-step explanation:
In an inverse variation situation, we have mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
So in this case: x*y is a constant
since x=9 and y=5 so
xy = 45
the constant of variation is 45
For inverse function, we usually write it as [tex]y = \dfrac{45}{x}[/tex]
The required solution of the value of the constant of variation is 45.
What is Inverse variation?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. It states if the value of one quantity increases, then the value of the other quantity decreases.
Given:
for an Inverse variation, y=5 when x=9
According to given question we have
Relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
x×y =constant
x×y =k
Where k is a constant.
By put the value of
y=5 when x=9.
k= 9×5
k=45
Therefore, the required solution of the value of the constant of variation is 45.

A coat check service charges $2 for the first hour and $1 for each addition hour or fraction of an hour. Which point is not included in the graph of this step function.
A: (2.5,3)
B: (2.0, 3)
C: (3.0, 4)
D: (3.5, 5)
The points not included in the graph are A: (2.5,3), B: (2.0, 3), C: (3.0, 4) and D: (3.5, 5)
How to determine the point is not included in the graphFrom the question, we have the following parameters that can be used in our computation:
Initial service charge = $2
Additional charges = $1 per hour
This means that the charges after x hours is
f(x) = Initial service charge + Additional charges * x
Substitute the known values in the above equation, so, we have the following representation
f(x) = 2 + x
Using the given points, we have
f(2.5) = 2 + 2.5 = 4.25
f(2.0) = 2 + 2.0 = 4.0
f(3.0) = 2 + 3.0 = 5.0
f(3.5) = 2 + 3.5 = 5.5
This means that all of the points are not in the graph

Write a polynomial P in lowest degree given the following roots: 4, -3, 4i
The polynomial P in lowest degree given the following roots: 4, -3, 4i is x^3 - (4i+1)x^2+4(i-3)x + 48i
Given the roots of a polynomial such as 4, -3, 4i. The equivalent factors of the polynomial will be x-4, x+3 and x-4i
Taking the product of the factors
P(x) = (x-4)(x+3)(x-4i)
P(x) = (x^2+3x-4x-12)(x-4i)
P(x) = (x^2 - x - 12)(x-4i)
P(x) = x^3-4x^2i-x^2+4xi-12x+48i
P(x) = x^3 - (4i+1)x^2+4(i-3)x + 48i
Hence the polynomial P in lowest degree given the following roots: 4, -3, 4i is x^3 - (4i+1)x^2+4(i-3)x + 48i

Marisa was tracking the diving speed of a bird. The average speed was 108 miles per hour. That means in one hour, the bird would travel 108 miles at that speed. However, these dives last far less than an hour, so Marisa needs to convert this to feet per second
By a change of units, we will get that 108 mi/h = 158.4 ft/s
Here we want to transform 108 mi/h to feet per second.
Then we will use two relations:
1 mi = 5,280 ft1 h = 3,600 sThen we can just transform as:
108mi/h = (108*5,280 ft)/h = 570,240 ft/h
570,240 ft/h = 570,240 ft/(3,600 s) = 158.4 ft/s
So we have:
108 mi/h = 158.4 ft/s
