The Mean Value Theorem can be used for a function f(x) that meets the following conditions: Continuous on the closed interval [a,b]. Differentiable on the open interval (a,b).
With these conditions met, there exists a point c on the open interval (a,b) such that:
f(b)−f(a) = f′(c)(b−a) .
The given function is f(x) = Vx x + 2x.
It is a continuous function over the closed interval [1, 4].
The derivative of the function is f′(x) = ½(x+1/x²).
We have to find a point c on the open interval (1, 4) such that:
f(4)−f(1) = f′(c)(4−1).
f(4) = V4×4 + 2×4
= 4V2+8.
f(1) = V1×1 + 2×1
= V2.
The equation becomes:
4V2+8 − 2V2 = f′(c)(3).
2V2+8 = f′(c)(3).
f′(c) = 2V2+8/3.
The function f′(x) is continuous and differentiable over the interval (1, 4).
We can apply the Intermediate Value Theorem to f′(x) on this interval.
Thus, f′(x) must take on the value 2V2+8/3 between x = 1 and x = 4.
Therefore, the point c that satisfies the conclusion of the Mean Value Theorem is in the open interval (1, 4).
The value of f′(c) must be equal to 2V2+8/3.

What is the radius of polygon JKLMN ?
Answer:
Radius of the circle is 5 units.
Step-by-step explanation:
JKLMN is a regular polygon inscribed in a circle.
Since, its a regular polygon,
JN = NM = 5.88 units
"Perpendicular drawn from the center of the circle to any chord is the bisector of the chord"
Therefore, PQ will be the perpendicular bisector of chord NM.
QM = \(\frac{1}{2}(NM)\)
QM = \(\frac{1}{2}(5.88)\)
QM = 2.94 units
By applying Pythagoras theorem in ΔPQM,
PM² = PQ² + QM²
PM² = (4.05)² + (2.94)²
PM = \(\sqrt{16.4025+8.6436}\)
PM = \(\sqrt{25.0461}\)
PM = 5 units
Therefore, radius of the circle is 5 units.

In a painting class, students learn about the mixing of colors. They need to pick out sets that show combinations of primary colors. Which ones will they pick
In a painting class, students will pick sets that show combinations of primary colors.
Primary colors are the basic colors from which all other colors can be created. In traditional color theory, the primary colors are red, blue, and yellow. When these colors are mixed together, they can produce a wide range of secondary and tertiary colors. To create a set of primary colors, students would choose combinations of red, blue, and yellow. For example, they might pick a set that includes pure red, pure blue, and pure yellow, allowing them to mix various shades and hues by combining these primary colors. By experimenting with different proportions and mixing techniques, students can create a vast array of colors using just the primary colors. Understanding the mixing of primary colors is fundamental in art, as it allows artists to achieve the desired color palette and effectively express their creative vision. By learning how primary colors interact and blend, students can develop a strong foundation in color theory and expand their artistic possibilities.

Step-by-step explanation:
We can use trigonometry to solve this problem. Let's draw a diagram:
```
A - observer (1.5 m above ground)

We want to find the height of the clock tower, which is CE. We have the angle of elevation ACD, which is 19 degrees, and the distance AB, which is 100 m. We can use tangent to find CE:
tan(ACD) = CE / AB
tan(19) = CE / 100
CE = 100 * tan(19)
CE ≈ 34.5 m (rounded to 1 decimal place)
Therefore, the height of the clock tower is approximately 34.5 m.

Martina is trying to find a factor pair for the number 62. She says that because 62 is an even number, then 2 has to be one of the factors in a factor pair.
Do you agree with Martina's reasoning? If you agree, find the missing factor. If you disagree, find another factor pair for 62. In either case, make sure you explain how you use one factor to find the other factor in the pair. Lucas says that 15 is both a prime number and a composite number.
State whether you agree or disagree with Lucas, and be sure to give a definition of either a prime or composite number to strengthen your argument.
I WILL MARK BRAINLIEST
Answer:
Look below
Step-by-step explanation:
Part A.
Martina is correct. This is because all even numbers have 2 as a factor.
We can use 2 to find the other factor. Let's use x to represent the other factor. We can set up an equation:
2x=62
Divide both sides by 2
x=31
The missing factor is 31
Part B.
Lucas is wrong. This is because a number cannot be both prime and composite.
A prime numbers' only factors are 1 and itself
A composite number has more than 2 factors.
If 15 was both prime and composite, Lucas is contradicting himself because having 2 factors and more than 2 factors at the same time is not possible.
We can also prove him wrong because...
15: 1, 3, 5, 15
Has more than 2 factors (it has 4 factors) therefore it is composite.
Martina is correct because all even numbers have 2 as a factor.
Lucas is incorrect because a number cannot be both prime and composite.
What is Prime and composite Number?A number with exactly two factors, "1" and the number itself, is referred to as a prime number.
A composite number can be divided by at least one positive integer in addition to being divisible by 1 and the number itself because it has more than two factors.
Given:
We know for even number 2 is most common factor.
Let x represent the other factor.
2x=62
x=31
So, The missing factor is 31
Now,
Lucas is incorrect . This is because a number cannot be both prime and composite.
A prime numbers only factors are 1 and itself and composite number has more than 2 factors.
Lucas would be in contradiction with himself if he claimed that 15 was both prime and composite, as it is impossible to have both two factors and more than two factors simultaneously.

Answer:
Anna will get 350 ZED
Step-by-step explanation:
since jenny is getting 3/8ths of the money, we can find how much money Jenny is getting and subtract that amount from the original total. to find this, take the original amount divided by the denominator then multiplied by the numerator.
for example: 560 / 8 = 70 × 3 = 210
560 - 210 = 350
350 is how much anna will get.
The three inside angles (A,B and C) of a right-angled triangle are in the ratio 7:18:11. Th smallest angle is 35. Work out angles A, B and C
Answer:
<A = 35degrees
<B =90degrees
<C = 55degrees
Step-by-step explanation:
Given the ratios of a triangle as 7:18:11
Total ratio = 7+18+11
Total ratio = 36
Since the smallest angle is 35degrees, hence <A = 35degrees
Get angle B;
<B = 18/36 * 180 (sum of angle in a triangle is 180degrees)
<B = 1/2 * 180
<B = 90degrees
Get angle C;
<C = 11/36 * 180
<C = 11 * 5
<C = 55degrees
Hence the value of A, B and C are 35, 90 and 55 degrees repectively
what is the mean absolute deviation of the following set 3 1 5 5 2 3 2 3 4 2
Answer:
30-3=27
Step-by-step explanation:
Finding the deviation of this is pretty simple
1) Find the mean
By finding the mean, you add the numbers together, and divide the sum by the number of numbers, in this case there are 10 numbers, so divide by 10
2) Subtract the data value, basically adding all of the numbers up, and subtracting it by 3, the mean.
the number sets:
3,1,5,5,2,3,2,3,4,2
mean=
30/10
by finding this, i added the numbers and divided it by the amount of numbers.
This would equal to 3.
Now, all you have to do is subtract 3 from the data value
The data value is 30, subtracted by 3 would be 27

On solving the provided question, we can say that - so, percentage - 400/500 X 100 = 80%
What is percentage?A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

Explanation
a ≡ b (mod n)
This means a and b have the same remainder when they are divided by n
So, to check if this question works out, we divide what is on the left hand side and what is on the right hand side by what is after the mod.
1) 67 × 73 ≡ 1 × 3 (mod 5)
4891 ≡ 3 (mod 5)
So, to check,
(4891/5) = 978 remainder 1
(3/5) = 0 remainder 3
The remainders are different.
So, this equation is wrong and does not work.
This equation is false.
2) 83¹⁴⁴ ≡ 15¹⁴⁴ (mod 17)
Noting that it is the units digit that determines the remainder
3 raised to the power of a multiple of 4 gives 81 raised to the power of a positive integer
5 raised to power of a multiple of 4 gives 625 raised to the power of a positive integer
So, using these numbers,
83¹⁴⁴ ≡ 15¹⁴⁴ (mod 17)
81 ≡ 625 (mod 17)
(81/17) = 4 remainder 13
(625/17) = 36 remainder 13
The remainders are the same.
So, this equation is correct and it works.
This equation is true.

x−m
R, where m
=n. Then____
The domain of the function is R - {m} and the range of the function is (-∞, ∞).
We are given a function f: R−{n}→R defined by f(x) = (x-n)/(x-m), where m ≠ n.
To find the domain of the function, we need to consider the values of x for which the denominator (x-m) is zero. Since m ≠ n, we have m - n ≠ 0, and therefore the function is defined for all x except x = m.
Therefore, the domain of the function is R - {m}.
To find the range of the function, we can consider the behavior of the function as x approaches infinity and negative infinity. As x approaches infinity, the numerator (x-n) grows without bound, while the denominator (x-m) also grows without bound, but at a slower rate. Therefore, the function approaches positive infinity.
Similarly, as x approaches negative infinity, the numerator (x-n) becomes very negative, while the denominator (x-m) also becomes very negative, but at a slower rate. Therefore, the function approaches negative infinity.
Thus, we can conclude that the range of the function is (-∞, ∞).
In summary, the domain of the function is R - {m} and the range of the function is (-∞, ∞).
