What are the minimum and maximum values of x, for which x3 + x2 – 6x ≥ 0? minimum = –3, maximum = 0 minimum = 0, maximum = 2 minimum = –3, no maximum minimum = 2, no maximum Please answer quickly
Answer: Option C.
Step-by-step explanation:
The given inequality is
[tex]x^3+x^2-6x\geq 0[/tex]
Taking x common, we get
[tex]x(x^2+x-6)\geq 0[/tex]
Splitting the middle term, we get
[tex]x(x^2+3x-2x-6)\geq 0[/tex]
[tex]x(x(x+3)-2(x+3))\geq 0[/tex]
[tex]x(x+3)(x-2)\geq 0[/tex]
Related equation is
[tex]x(x+3)(x-2)=0[/tex]
[tex]x=-3,0,2[/tex]
These three points divide the number line in 4 parts.
Interval Sign of [tex]x(x+3)(x-2)\geq 0[/tex] Statement
(-∞,-3) [tex](-)(-)(-)=(-)[/tex] False
(-3,0) [tex](-)(+)(-)=(+)[/tex] True
(0,2) [tex](+)(+)(-)=(-)[/tex] False
(2,∞) [tex](+)(+)(+)=(+)[/tex] True
So, the solution set is (-3,0) ∪ (2,∞).
Thus, minimum value is –3 and no maximum value.
Therefore, the correct option is C.
Answer:
minimum = –3, no maximum

Ben drank 1/5 pitcher of lemonade. Tonya drank 1/2 of the lemonade. How much lemonade did they drink together?
Answer:
7/10ths of the picture has been digested.
Step-by-step explanation:
Let's divide this into tenths.
One fifth out of ten is equal to two, since 10/5 = 2. A half of ten is five, because 10/2 = 5. Adding five and two together gives us 7/10ths, which can not be reduced to a smaller amount.

Answer: a=56/15
Step-by-step explanation:
For this problems, it is important ot know how to read ratios. They can be read as fractions. Knowing this, we would use proportions to solve.
[tex]\frac{3a}{7} =\frac{8}{5}[/tex] [cross multiply]
[tex]15a=56[/tex] [divide both sides by 15]
[tex]a=\frac{56}{15}[/tex]
Now, we know that a=56/15.
Answer:

what is the value of x in the equation as a fraction 2(5x+4)=17
Answer:
x= 9/10
Step-by-step explanation:
2(5x+4)=17
Distribute
10x +8 = 17
Subtract 8 from each side
10x+8-8=17-8
10x = 9
Divid by 10
10x/10 = 9/10
x= 9/10
Divide both sides by 2:
5x + 4 = 8.5
Subtract both sides by 4:
5x = 8.5 - 4 = 4.5
Divide both sides by 5:
x = 4.5 / 5 = 0.9 or 9/10

I need to find the measurement of AEB please help me!
Triangle BEC is an isosceles triangle.
The angles opposite the congruent sides are equal
x = measure of missing angle
180 = 54 + 2x
Subtract 54 from both sides
126 = 2x
Divide both sides by 2
63 = x
angle EBC and angle C = 63 degrees
Angle EBC and angle EBA are supplementary.
This means they add up to 180 degrees
180 = 63 + EBA
Subtract 63 from both sides
117 = EBA
the measure of a triangle = 180
Therefore,
The measure of angle AEB = 180 - (40 + 117) = 23 degrees

quotient of twice a number and 6 is 42
Answer:
[tex]n = 126[/tex]
Step-by-step explanation:
First let's model this into an equation.
Twice a number is [tex]2n[/tex], and that divided by 6 is [tex]\frac{2n}{6}[/tex]. That's equal to 42, so we have [tex]\frac{2n}{6} = 42[/tex].
Now we can simplify this equation by isolating n on one side of the equation.
Multiply both sides by 6:
[tex]\frac{2n}{6} \cdot 6 = 42\cdot 6\\\\2n = 252[/tex]
Divide both sides by 2:
[tex]2n \div 2 = 252\div 2\\\\n = 126[/tex]

LaVilla is a village in the Italian Alps. Given its enormous popularity among Swiss, German, Austrian, and Italian skiers, all of its beds are always booked in the winter season, and there are, on average, 1465 skiers in the village. On average, skiers stay in LaVilla for 11 days. How many new skiers are arriving - on average - in LaVilla every day
Answer:
There are approximately 133 new skiers arriving every day
Step-by-step explanation:
Total number of skiers = 1465
time of stay for skiers = 11 days
How many new skiers are arriving on average = ???
To keep the average number of skiers available at each time constant, the number of skiers coming in and going out are fairly constant, and this is gotten by using the flow rate formula.
flow rate = amount available ÷ flow time
flow rate = 1465 ÷ 11
flow rate = 133.18
flow rate = 133
∴ There are approximately 133 new skiers arriving every day
Suppose there are 11 freshman, 7 sophomores, 13 juniors, and 15 seniors running for the offices of president, vice president, and secretary. If no person can hold more than one office, in how many different ways could these people be elected to these positions if the president must be a senior and the secretary must be a freshman
Answer:
7,260 ways
Step-by-step explanation:
Here, we are told that the president must be a senior and the secretary must be a freshman.
Now for the post of President, we have 15 choices to pick from
For the post of secretary, we have 11 choices to pick from
Now the last position, the vice president
Firstly , we have 14 seniors( 1 already president), 10 freshmen(1 already secretary) , 6 sophomores and 13 juniors
So the total number of choices will be;
14 + 10 + 7 + 13 = 44
So the number of ways will be;
44 * 15 * 11 = 7,260 ways

Step-by-step explanation:
given;
Planet Earth has an approximate diameter of 1.2742 x 10¹⁰ millimeters.
The sun has a diameter of 1.391 x 10⁶ kilometers.
find:
Part I:
Given that for every one kilometer there are 1,000,000 millimeters, which unit of measurement should be used to best represent the lengths of the sun and Earth's diameters?
Part II:
Approximate how many times greater the sun's diameter is than planet Earth's.
-------------------------------------------------------------------------------------------------------
part I:
the best measurement to represent the lengths of the sun and Earth's diameters is kilometers.
= planet dia. = 1.2742 x 10¹⁰ mm x 1 km = 12,742 km
1,000,000 mm
= sun dia. = 1.391 x 10⁶ km = 1,391 x 10³ km = 1,391,000 km
part II:
the approximate scale dia ratio of earth to sun is = sun dia. over earth's dia.
= 1,391,000 km
12,742 km
= 109.17 times
therefore,
109.17 times greater the sun's diameter is than planet Earth's.

What are arithmetic operators?Arithmetic operations are a set of four basic operations to be performed to add, subtract, multiply or divide two or more quantities. These are also known as mathematical operations.
Addition
The addition is a basic mathematical skill of finding or calculating the total of two or more numbers, or we can say in simple words adding things together. It is denoted by the symbol ‘+’.
Subtraction
The subtraction arithmetic operation shows the difference between two numbers. It is denoted by the symbol ‘-‘. Subtraction is mostly used to find out what is left when things are taken away.
Multiplication
The repeated addition is known as multiplication. It is represented by the symbol ‘×’. Multiplication as an arithmetic operation helps us to find out the total when a number is repeating itself a number of times.
Division
The division is an act of dividing something into equal parts or groups. It is one of the four basic arithmetic operations which gives a fair result of equal sharing.
Option A :
Given
A bird flies 25 feet up in the air. It then flies 25 feet across to its
nest.
So, total distance flown by bird = 25 + 25 = 50 feet
Which do not combine to 0.
Option C :
A player in a game earns 4 points for getting an answer right. She
then earns 4 points for making it around the board.
Hence, total points earned = 4 + 4 = 8
Which do not combine to 0.
Option D :
A car is filled with 10 gallons of gas, Half of the 10 gallons are
then used on a day's drive.
= 10 - [tex]\frac{1}{2}[/tex] × 10
= 10 - 5
= 5
Which do not combine to 0.
Option B :
Veronica receives $21 for babysitting. She then spends $21 on a
new shirt.
So net amount left with Veronica = 21 - 21 = 0
Hence, it combines to zero.

Select the two characteristics that apply.a. Integrated Communicationsb. Establishment and Transfer of Commandc. Chain of Command and Unity of Commandd. Accountabilitye. Dispatch/Deploymentf. Information and Intelligence Management
Answer: Chain of Command and Unity of Command ; Information and Intelligence Management
Step-by-step explanation:
Chain of Command typically loooks into an organization's hierarchical structure while unity of commands simply has to do with the reporting to ones designated supervisor.
Also, because maps are being produced, there'll be with the gathering, assessing, analyzing, sharing, and managing intelligence.
Therefore, the NIMS Management Characteristics that'll be supported are Chain of Command and Unity of Command ; Information and Intelligence Management.
The NIMS management characteristics that are mostly supported are:
A chain of Command is a unity of command.information and intelligence management.The chain of command and unity of command is an overall hierarchy of the orpganization, while the unity of command says that the entire chain is always reporting to the similarly designated supervisor.
The information and intelligent management help the owner to take according to decisions forward premises of the information system.
As per the GIS when the maps have the process for the information would be gathering the information, assessing it, analyzing it, sharing the information to the delegated conducting the field, and then managing the intelligence of the information.
Thus, the NIS characteristics are chain and unity of command, and information and intelligence management.
