Find f(27) and f(-343)
need to find cube root
On solving the provided question, we can say that - the value of the cube root is 19683 = 27
what is cube root?In mathematics, y3 = x since the cube root of a number x equals a number y. Each non-zero real integer has precisely one real cube root, one set of complex conjugate cube roots, and three different complex cube roots. When a number is multiplied three times, the result is the cube root of that number. Three cube roots, the final cube root, is the symbol for the cube root. The opposite of cubing an integer is finding the cube root of that number. Prime factorization is a fairly straightforward technique that may be used to get a number's cube root. The sign stands for a cube root.

What is true about the domain and range of the function?
O The domain is all real numbers, and the range is all
real numbers greater than or equal to -4.
O The domain is all real numbers greater than or equal
to
-4, and the range is all real numbers.
O The domain is all real numbers such that -6 ≤x≤-2,
and the range is all real numbers greater than or equal
to-4.
O The domain is all real numbers greater than or equal
to
-4, and the range is all real numbers such that -6 sx
≤-2.
The domain of a function is the set of all input values (x-values) for which the function produces a valid output (y-value). In this case, the function f(x) = (x+2)(x+6) is defined for all real numbers, so the domain is all real numbers.
What do a function example's range and domain mean?
A straightforward function, such as f(x) = x2, can have a domain (what goes in) of just the counting numbers 1, 2, 3, etc., and a range (what comes out) of the set 1, 4, 9, etc. Another function, g(x) = x2, may have an integer domain of..., -3, -2, -1, 0... 1, 2, 3, and its range is..., 1, 4, 9,...
The range of a function is the set of all possible output values (y-values) produced by the function. The function f(x) = (x+2)(x+6) is a polynomial, and all polynomials of the form (ax^2 + bx + c) with real coefficients (a,b,c) have range is all real numbers. The range of the function f(x) = (x+2)(x+6) is also all real numbers.
So the answer is
The domain is all real numbers, and the range is all
real numbers.

On Thursday, a local hamburger shop sold a combined total of 429 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the
number of hamburgers sold. How many hamburgers were sold on Thursday?
hamburgers
Let H be the number of hamburgers sold and C be the number of cheeseburgers sold.
The total number of hamburgers and cheeseburgers sold is given by the equation: H + C = 429
The number of cheeseburgers sold is given by the equation: C = 2H
Substituting the second equation into the first equation, we get: H + 2H = 429
Combining like terms, we get: 3H = 429
Dividing both sides by 3, we get: H = 143
On Thursday, 143 hamburgers were sold.
Find the 35th term for the sequence: 12, 9.5, 7, 4.5...
Answer:
-73
Step-by-step explanation:
So to begin you must find where you start on a graph. To do this you can go backwards from your first number and in this situation it would be 14.5 because the slope is -2.5x. I will use y as the answer.
y=-2.5x+14.5
From here you plug in how many terms are neeeded for the correct answer. In this situation there is 35 terms needed.
y=-2.5(35)+14.5
Solve this equation to get your answer.
y=-73
Answer:
The 35th term is - 73.----------------------------
Given sequence:
12, 9.5, 7, 4.5...This is an AP with the common difference of:
d = 4.5 - 7 = 7 - 9.5 = 9.5 - 12 = - 2.5The first term is a = 12.
Use the nth term equation to find the 35th term:
aₙ = a + (n - 1)da₃₅ = 12 + (35 - 1)(- 2.5) = 12 - 34*2.5 = 12 - 85 = - 73Simplifying algebraic expressions

Pick any two points on the line to apply the slope formula.
I'll select (-5,1) and (5,-1)
[tex](x_1,y_1) = (-5,1) \text{ and } (x_2,y_2) = (5,-1)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{\text{y}_{2} - \text{y}_{1}}{\text{x}_{2} - \text{x}_{1}}\\\\m = \frac{-1 - 1}{5 - (-5)}\\\\m = \frac{-1 - 1}{5 + 5}\\\\m = \frac{-2}{10}\\\\m = -\frac{1}{5}\\\\[/tex]
The slope as a fraction is -1/5
A slope of -1/5 means " go down 1, then to the right 5 units".
An example of this motion is when going from (-5,1) to (0,0)
Another example would be going from (0,0) to (5,-1)
----------
The "down 1, right 5" motion is because
slope = rise/run = -1/5rise = -1 = go down 1run = 5 = go to the right 5How many solutions does 5x 2 7x 4 0 have?

5-Which of the equłtions represents the circle below?
A) x2 + y² = 12
B) x2 + y2 = 36
o +vy=v12
D) Vx+vy=v6
Answer:
The equator the circle is;
x^2 + y^2 = 36
Step-by-step explanation:
The general equation of a circle is ;
(x-a)^2 + (y-b)^2 = r^2
(a,b) is the center of the circle which is the origin here
The radius is half the distance from edge to edge, passing through the center either in the vertical or horizontal direction
From the center to the edge of the positive x axis bounding the circle, we have 6 units
This would be the same for the left too
So, the diameter of the circle would be 6 + 6 = 12 units
The radius of the circle is half of this which would be 12/2 = 6 units
thus, we have the equation of the circle as;
(x-0)^2 + (y-0)^2 = 6^2
x^2 + y^2 = 36

solve the inequality and explain how
Answer:
B. (see attached)
Step-by-step explanation:
You want the solution and graph of the inequality |x+3| > 2.
SolutionThe inequality resolves to two inequalities with different domain definitions:
|x +3| > 2
When the argument is negative, (x+3) < 0, this is ...
-(x +3) > 2
-x -3 > 2 . . . . . . eliminate parentheses
x +3 < -2 . . . . . . multiply by -1
x < -5 . . . . . . . . . subtract 3; consistent with the domain definition
When the argument is positive, (x+3) > 0, this is ...
x +3 > 2
x > -1 . . . . . . . . subtract 3
-1 < x . . . . . . . . same thing using the < symbol
These differing solution sets do not overlap, but elements of either set are solutions to the inequality. The appropriate conjunction is "OR":
solution: x < -5 or -1 < x
The graph is attached.
__
Additional comment
We like to use the < or ≤ symbols when expressing the solution to an inequality. That way, the relation of the variable to the boundary value is the same as its relation on a number line. Solution values are left of -5 or right of -1:
x < -5 or -1 < x
It helps provide a check that the graph is properly drawn.
The inequality can be rewritten as ...
|x -(-3)| > 2
which can be interpreted as saying the positive distance from x to -3 is more than 2. This tells you the graph will have two disjoint branches, and the appropriate conjunction is OR.
If the problem were different, and the inequality were ...
|x -(-3)| < 2
it would be telling you the solution values have a distance less than 2 from -3. They will be in one continuous band from -5 to -1, so the appropriate conjunction is AND. The solution in this case is usually written as a compound inequality with no conjunction: -5 < x < -1. (Note the use of < symbols puts the variable value in the middle, between the boundary values, as in graph D.)
In a survey 1500 people , 775 of them like nepal idol , 975 like comedy chapion and 450 people like both the showes how many people didnot like both the show
Answer:
Step-by-step explanation:
Hope this helps u!!
There will be 800 people who did not like either show.
What is a survey?To find out how many people did not like either show, we need to subtract the number of people who liked both shows from the total number of people surveyed.
Let A be the number of people who liked Nepal Idol, B be the number of people who liked Comedy Champion, and C be the number of people who liked both shows.
According to the problem, we have:
A = 775
B = 975
C = 450
To find the number of people who did not like either show, we can use the formula:
Total number surveyed - (A + B - C)
Substituting the values given in the problem, we get:
1500 - (775 + 975 - 450) = 800
Therefore, 800 people did not like either show.
