What’s is the median for this number
8,9,3,1,2,6,5,7,4,0,10
Answer:
To find the median, set the numbers in order and the median is the number in the middle. If there was an even number of number then you would the two middle numbers and average it.
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
So the median in this case would be 5
Answer: 6
Step-by-step explanation:
Median means the middle. You cross out a number from each side until you get one number and it’s 6. If there was uneven amount of numbers, and you were left with two numbers you add them and divide of how many numbers there are

Factor sum or difference of cubes
Answer:
(4x -5)(16x^2 +20x +25)
Step-by-step explanation:
The factoring of the difference of cubes is something you might want to memorize, or keep handy:
(a³ -b³) = (a -b)(a² +ab +b²)
Here, the minus sign in the middle tells you this is a difference. The power of x is a clue that this might be the difference of cubes. Your knowledge of cubes of small integers tells you ...
64 = 4³125 = 5³so you can recognize this as ...
(4x)³ - 5³ . . . . . the difference of cubes.
___
Since you are familiar with the factorization above, you can easily write down the factoring of this expression using a=4x, b=5.
(4x -5)(16x² +20x +25)
_____
For "completeness", here is the factorization of the sum of cubes:
a³ +b³ = (a +b)(a² -ab +b²)
Note the linear factor (a +b) has the same sign as the sign between the cubes. The sign of the middle 2nd-degree term (ab) is opposite that.
A flagpole stands in the middle of a flat, level field. 50 feet away from its base, a surveyor measures the angle to the top of the flagpole as 48 degrees. How tall is the flagpole? Round to the nearest hundredth of a foot
Answer:
55.53 feet.
Step-by-step explanation:
We have been given that a flagpole stands in the middle of a flat, level field. 50 feet away from its base, a surveyor measures the angle to the top of the flagpole as 48 degrees.
We can see from attached photo that flagpole, the surveyor forms a right triangle with respect to ground.
[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]
[tex]\text{tan}(48^{\circ})=\frac{h}{50}[/tex]
[tex]\text{tan}(48^{\circ})*50=\frac{h}{50}*50[/tex]
[tex]1.110612514829*50=h[/tex]
[tex]h=1.110612514829*50[/tex]
[tex]h=55.53062574[/tex]
[tex]h\approx 55.53[/tex]
Therefore, the height of the flagpole is approximately 55.53 feet.

You can treat the smaller units as a fraction of the larger unit: 23 7/12 -13 11/12. Then subtracting mixed numbers proceeds in any of the usual ways. You may even be able to use a calculator for this.You can "subtract by adding": 8 inches added to the subtrahend makes it 14 ft 7 in; then adding 9 ft makes it 23 ft 7 in.

What effect does changing the function f(x)=2sin(x/2)−1 to the function g(x)=2sin(x)−5 have on the graph of f(x)?
Changing the function f(x)=2sin(x/2)-1 to the function g(x)=2sin(x)-5 shifts the graph of f(x) downward by 4 units and changes the period from 4π to 2π.
Explanation:Changing the function f(x)=2sin(x/2)-1 to the function g(x)=2sin(x)-5 has the effect of shifting the graph of f(x) downward by 4 units and changing the period of the graph from 4π to 2π.
By comparing the two functions, we can see that the constant -1 in f(x) has changed to -5 in g(x), resulting in a downward shift of 4 units. The factor of 1/2 in the argument of the sine function in f(x) has been removed in g(x), which changes the period from 4π to 2π.
Overall, the graph of f(x) has been shifted downward and compressed horizontally to form the graph of g(x).

For a us census clock based on the 2000 census, the birth light would flash every 10 seconds, the death light every 16 seconds, the immigration light every 81 seconds, and the emigration light every 900 seconds, to indicate gains and losses in population.
A. If the birth and death lights flashed at the same time, how many seconds would pass before they flashed together again?
Show work
Answer:80
Step-by-step explanation:
Let's pretend we start a stopwatch when the birth and death light flash together. The birth light will flash at 10 seconds, 20 seconds, 30 seconds, etc. The death light will flash at 16 seconds, 32 seconds, 48 seconds, etc.
So the trick here is to find the least common multiple (LCM) of 10 and 16. To do that, we write the prime factorization of each:
10 = 2×5
16 = 2⁴
The LCM must include all these prime factors without any duplicates. So the LCM = 2⁴×5 = 80. We can check our answer by dividing:
80 / 10 = 8
80 / 16 = 5
So 80 is indeed a multiple of both 10 and 16.
By using the concept of HCF and LCM, the result obtained is
The birth and death light will flash again after 80 seconds.
What is HCF and LCM of two numbers?
HCF means Highest Common Factors. HCF of two numbers a and b is the highest number which divides both a and b
LCM means Lowest Common multiple. LCM of two numbers a and b is the lowest numbers which is divisible by both a and b
HCF and LCM can be calculated by division method and prime factorization method.
Also there is an important formula relating HCF and LCM
HCF [tex]\times[/tex] LCM = Product of two numbers
Here,
The birth light would flash every 10 seconds,
The death light every 16 seconds,
The immigration light every 81 seconds,
The emigration light every 900 seconds,
They will flash again after LCM (10, 16)
Now,
10 = [tex]2 \times 5[/tex]
16 = [tex]2 \times 2 \times 2 \times 2[/tex]
LCM of 10 and 16 = [tex]2 \times 2 \times 2 \times 2 \times 5[/tex] = 80
The birth and death light will flash again after 80 seconds.

To find the absolute maximum and minimum values of the function f(x) = x^5 - x^3 + 6, we can use both a graphical approach and a calculus approach. The graphical approach involves plotting the function and identifying the highest and lowest points on the graph. The calculus approach involves taking the derivative of the function, finding critical points, and evaluating the second derivative to determine whether the critical points are maximum or minimum values.
Explanation:Graphical approach:
To find the absolute maximum and minimum values of the function, we need to graph it within the given interval and identify the highest and lowest points. By plotting the function and examining the graph, we can see that the absolute maximum value is approximately 6.66 at x ≈ 1, and the absolute minimum value is approximately 5.33 at x ≈ -1.
To find the exact maximum and minimum values, we need to use calculus. We take the derivative of the function f(x) = x^5 - x^3 + 6, which is f'(x) = 5x^4 - 3x^2. Setting f'(x) = 0 and solving for x, we find that x = 0 is a critical point. To determine whether it is a maximum or minimum, we take the second derivative f''(x) = 20x^3 - 6x and evaluate it at x = 0. Since f''(0) > 0, x = 0 is a relative minimum. Plugging x values outside the given interval into the function, we find that f(-1) ≈ 5.33 is the exact minimum value, and f(1) ≈ 6.66 is the exact maximum value.
