Identify h (x) = [x] + 4
A. Constant function
B. Greatest integer function
C. Direct Variation function
D. Absolute value function
PLEASE HELP ILL MARK BRIANLIEST
Answer:
C
Step-by-step explanation:
The given function h (x) = [x] + 4 as the greatest integer function which is the correct answer would be option (B).
What is the greatest integer function?The greatest integer function takes the greatest integer that is less than or equal to a specified value. The biggest integer less than or equal to a number x is expressed as ⌊x⌋. It will round off the input number to the nearest integer that is less than or equal to the number itself.
Mathematically, the greatest integer function ⌊x⌋ can be defined as follows:
⌊x⌋ = n, where n ≤ x < n + 1 and 'n' is an integer.
According to the given question,
The function is below as
⇒ h (x) = [x] + 4
Here ⌊x⌋ = 4, where 4 ≤ x < 4 + 1 and '4' is an integer.
The given function as the greatest integer function takes the greatest integer that is less than or equal to a value of 4.
Hence, the correct answer would be an option (B).

Answer:
x = 45
Step-by-step explanation:
180-136 = 44
x - 1 = 44
x = 44 + 1
x = 45
x = 45°
Step-by-step explanation:
The two angles are supplementary so
[tex]136° + (x-1) = 180°[/tex]
[tex]\Rightarrow x - 1 = 44°[/tex]
or

1 * w^3
how do you multiply these together
9514 1404 393
Answer:
w^3
Step-by-step explanation:
The multiplicative identity element is 1. That means 1 times anything is just that thing.
1 × w^3 = w^3
_____
Additional comment
That is one of the reasons why a coefficient of 1 is (almost) never shown.
In algebra, multiplication can be indicated a number of ways.
ab . . . . placing values next to each other (sometimes with a small space)
(a)(b) . . . . placing values next to each other with either or both in parentheses
a·b . . . . . using a multiplication symbol between the values.
There are several different multiplication symbols in common use:
* — asterisk
· or • — centered dot
× — centered "x" multiplication symbol
x — the lower-case letter x (when it cannot be confused with a variable)
. — a period (when it cannot be confused with a decimal point). This is uncommon in the US, but is seen occasionally when some of the other symbols are not available. It is more common outside the US.
_____
The multiplication of a constant and a variable expression cannot actually be accomplished. It can only be "indicated." If you wanted to multiply 2*w^3, that product would be indicated in any of the ways described above. Perhaps the simplest and least-confusing to most people is ...
2w^3
Multiplying 1*w^3 can be indicated the same way: 1*w^3. In view of the special treatment given to a coefficient of 1, we would not simplify this to
1w^3
Rather, we would simplify it to ...
w^3
The number of children at the library was 3 times the number adults. The total number of people at the library was 48. How many children were at the library
A 12
B 24
C 32
D 36
Answer:
D 36
Step-by-step explanation:
Write the information algebraically
c = 3a
c + a = 48
c = children, a = adults
In the second sentence (in bold), we can replace c with 3a
c + a = 48 → 3a + a = 48
Simplify
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
We can then substitute or plug in a = 12 into the original equation:
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)
There are 36 childrenLength of rectangle is 4 m less than 3 times its breadth. If the perimeter of rectangle is 32 m. Find its length and breadth B=12
Answer:
Length = 11m and the Breath = 4m
Step-by-step explanation:
L = 3B - 4
p = 32m
2( L + B ) = 32
L + B = 32/2
L + B = 16
(3B - 4) + B = 16
3B - 4 + B = 16
4B - 4 = 16
4B = 16 + 4
4B = 20
B = 20/4 = 5m
B = 5m
L = 3B - 4
L = 3(5) - 4
L = 15 - 4
L = 11m

Answer:
400 minutes
Step-by-step explanation:
The cost of the first plan is ...
A = 14 + 0.15m . . . . . . . . where m is the number of minutes used
The cost of the second plan is ...
B = 30 + 0.11m
The costs will be equal when ...
14 +0.15m = 30 +0.11m
0.04m = 16 . . . . . . . . . . . . . subtract 14+0.11m from both sides
m = 400 . . . . . . . . . . . . . . . divide by 0.04
The plans will have the same cost for 400 minutes of calls.

researchers in New York city did a study on ice cream sales and murder rates in the city. this graph was included in the results
after seeing this graph as a picture with the headline "ice cream sales causes murder rates to increase" shared on social media by her best friend's second cousin, the president of a prominent HOA in the Hamptons decided to petition to ban the sale of ice cream so that people would stop being murdered .
this is the question - compare and contrast what you see on the graph.
second part to the question - was the HOA president right for doing so ? what other factors could have contributed to both the rise in ice cream sales and murders? is this an example of correlation or causation?
The presence of a correlation between statistical variables is an indication
of the existence of a relationship variables, it however, does not imply
direct causation.
Part one:
The similarities of the graphs are;
The rate of change in the sale ice cream and rate of murder are almost equal.The peak of ice cream sales and murder rate occur at the same time of the year.The rate of decrease in the sale of ice cream and murder rate are equal between the months of July and December.The differences are;
The shape of the ice cream sale graph is more bell shapes than the graph of murder rates.The murder rates occur over a slightly more longer period than than the sale of ice cream.There is a sharp decrease in the murder rate in the month of February while the ice cream sales increases steadily from January to July.Second part;
The HOA president's petition is in line with the social media post based on the graph.
The graph shows a strong correlation between murder rates and ice cream sales, however, selling ice cream, and murder are unrelated events.
The correlation between the sale of ice cream and murder is an indication of the existence of a common third factor.
Based on the time of the year dependence of the two variables, which corresponds to hot and cold weather, there is a correlation of both the murder rate and ice cream sales with temperature.
Therefore, the HOA president is not right for doing so

You deposit $200 in a savings
account that pays a simple
interest rate of 3.25% per year.
How much interest will you earn
after 5 years?
Answer:
$32.50
Step-by-step explanation:
The equation for simple interest is
Simple Interest=P×r×n
where:
P=Principal amount
r=Annual interest rate
n=Term of loan, in years
so
P=200
r=0.0325
n=5
so 200*0.0325*5=32.5

Can Pi be written as a fraction?
Answer:
no
Step-by-step explanation:
1. Pi is an irrational number, and irrational numbers CANNOT be written as a fraction. Pi is a non-repeating, non-terminating decimal number.
2. While 22/7 and 3.14 is often used as a value for pi, these are just approximations, so they're not completely exact.

Answer:
[tex] x = -2 [/tex] or [tex] x= -3 [/tex]
The solution is real.
Step-by-step explanation:
x^2 + 5x + 6 = 0
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] x = \dfrac{-5 \pm \sqrt{5^2 - 4(1)(6)}}{2(1)} [/tex]
[tex] x = \dfrac{-5 \pm \sqrt{25 - 24}}{2} [/tex]
[tex] x = \dfrac{-5 \pm \sqrt{1}}{2} [/tex]
[tex] x = \dfrac{-4}{2} [/tex] or [tex] x = \dfrac{-6}{2} [/tex]
[tex] x = -2 [/tex] or [tex] x= -3 [/tex]
