If f(x)=13x3−4x2+12x−5 and the domain is the set of all x such that 0≤x≤9 , then the absolute maximum value of the function f occurs when x is
The correct format of the question is
If f(x)= \(\frac{1}{3}x^3 -4x^2+12x -5\) and the domain is the set of all x such that 0≤x≤9 , then the absolute maximum value of the function f occurs when x is
Answer:
The absolute maximum value of the function F(x) occurs when x is 9
Step-by-step explanation:
F'(x) = \(x^2 -8x +12= 0\)
= (x-6)(x-2) = 0
x = 2,6
so we have boundary points 0 , 9 and 2,6
The value of function at these four points
x = 0 2 6 9
F(x) = -5 17/3 -5 22
So the absolute maximum value of the given function is x = 9 and F(x) is 22.
The absolute maximum value of the function f occurs when x is 9 and this can be determined by differentiating f(x) and then equating it to zero.
Given :
\(\rm f(x)=\dfrac{1}{3}x^3-4x^2+12x-5\)The domain is the set of all x such that 0≤x≤9In order to determine the absolute maximum value of function f(x), differentiate f(x) and then equate it to zero.
\(\rm f'(x)=\dfrac{1}{3}\times(3x^2)-8x+12\)
Now, equate the above equation to zero.
\(x^2-8x+12 = 0\)
Factorize the above quadratic equation.
\(x^2-6x-2x+12=0\)
x(x - 6) - 2(x - 6) = 0
(x - 6)(x - 2) = 0
Now, determine the value of f(x) at x = 0, 2, 6, 9
f(0) = -5
f(2) = 1/3.(8) - 4(4) + 12(2) - 5
f(2) = 17/3
f(6) = 72 - 144 + 72 - 5
f(6) = -5
f(9) = 243 - 324 + 108 - 5
f(9) = 22
So, the absolute maximum value of the function f occurs when x is 9.

a person rolls a standard six-sided die 6 6 times. in how many ways can he get 3 3 fives, 2 2 sixes, and 1 1 two?
The person can get 3 fives, 2 sixes, and 1 two in 336 ways.
To find the number of ways to roll 3 fives, 2 sixes, and 1 two in 6 rolls of a standard six-sided die, we can use the formula for combinations with repetition:
\(C(n + k - 1, k) = C(6 + 3 - 1, 3) * C(3 + 2 - 1, 2) * C(1 + 1 - 1, 1)\)
where n is the number of possible outcomes (in this case, 6), k is the number of choices to make (in this case, 3 for fives, 2 for sixes, and 1 for twos), and C(n + k - 1, k) represents the number of combinations with repetition.
Using this formula, we can calculate:
\(C(8, 3) * C(4, 2) * C(1, 1) = 56 * 6 * 1 = 336\)
Therefore, there are 336 ways to roll 3 fives, 2 sixes, and 1 two in 6 rolls of a standard six-sided die.

An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.
Two triangles - ΔJKL and ΔPQR is given.
It is given that both the triangles are similar.
In ΔJKL, the ∠LJK = 35° and in ΔPQR, the ∠RPQ = 35°.
In ΔJKL, the measurement of line segment LJ is = 28 units
In ΔJKL, the measurement of line segment KJ is = x units
In ΔPQR, the measurement of line segment RP is = 42 units
In ΔPQR, the measurement of line segment QP is = 33 units
To find the value of x use the method of indirect measurement.
According to the rule of indirect measurement -
LJ/RP = KJ/33
Substituting the values into the equation -
28 / 42 = x / 33
28 × 33 = 42x
x = (28 × 33) / 42

Option 234 cm is the correct option.
The measurement equivalent to 2.34 meters is: 234 cm
To convert meters to centimeters,
you multiply the number of meters by
100.
So, 2.34 meters multiplied by 100 is equal to 234 centimeters.
An object is only identified or classified using numbers on a nominal scale, which is a measuring scale. Only non-numeric (quantitative) factors or situations where numbers have no meaning are often addressed by this assessment.
By increasing the number of metres by 100, one may convert measurements from metres to centimetres. One metre equals one hundred centimetres, or 1 m = 100 cm, as is common knowledge.
Cm is used to represent it in writing. It may also be described as the unit of length in the current metric system, the International System of Units (SI). It is equal to one hundredth of a metre.

Which value of x satisfies the inequality below?
13< x
Answer:
20
Step-by-step explanation:
since the sign is pointing to the "greater number"
any number over 13 is fine
The value of x can be 14, 15, .... and so on.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
For example, In the 12U Softball division, Olivia gets chosen. What is Olivia's age? Olivia's age is unknown to you because the word "equals" is missing. However, since you are aware that she should be under or equal to 12, you can write Olivia's Age ≤ 12. This is a real-world example of an inequality.
Given:
13< x
So, we have to choose the value which are greater than 13.
The value of x cannot be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13.
Thus, the value of x can be satisfies by 14, 15, .... and so on.

3.The simplified expression is 81y^8z^20.
4.The simplified expression is 200x^5y^18
1. (∜x^3)*(√x)
Using the property of fractional exponents, we can rewrite the expression as:
(x^(3/4)) * (x^(1/2))
Applying the law of raising powers, we can multiply the two terms:
x^((3/4) + (1/2))
Simplifying the exponents:
x^(3/4 + 2/4)
x^(5/4)
Therefore, the simplified expression is ∛x^5.
2. ∛2 ÷ ∜2
Using fractional exponents, we can express the expression as:
2^(1/3) ÷ 2^(1/4)
Applying the law of raising powers, we can subtract the exponents:
2^((1/3) - (1/4))
Simplifying the exponents:
2^((4/12) - (3/12))
2^(1/12)
Therefore, the simplified expression is ∛2^(1/12).
3. ((3y^2)z^5)^4
Using the law of raising powers, we can apply the exponent to each term inside the parentheses:
(3^4)(y^(2*4))(z^(5*4))

The carousel at an amusement park has 20 horses spaced evenly around its circumference. The horses are numbered consecutively from 1 to 20. The carousel completes one rotation about its axis every 40 seconds.
a. What is the central angle, in degrees, formed by horse #1 and horse #8?
b. What is the speed of the carousel in rotations per minute?
c. What is the speed of the carousel in radians per minute?
d. A child rides the carousel for 6 minutes. Through how many radians will the child pass in the course of the carousel ride?
The child passes through 18π radians in the course of the carousel ride.
To determine the number of radians the child passes during the 6-minute ride on the carousel, we need to know the distance traveled in terms of radians.
Since there are 20 horses spaced evenly around the carousel, each horse is separated by an angle of 360/20 = 18 degrees or π/10 radians.
Therefore, during one rotation of the carousel, the child passes through 20π/10 = 2π radians. And since the carousel completes one rotation every 40 seconds, the angular velocity is 2π/40 = π/20 radians per second.
To find the total distance traveled in radians during a 6-minute ride, we need to multiply the angular velocity by the time elapsed.
6 minutes is equal to 360 seconds,
so the child passes through π/20 x 360 = 18π radians during the ride.

Answer:
Solve using the supplement of the angles.
Step-by-step explanation:
For the first page, you should use the supplement of the angles. This means, on a straight line, you can subtract the known angle from 180 degrees to find the missing angle. The top angle, for example, will be 180 - 46 resulting in the interior angle being 134 degrees.
You can do this until you find all of the known interior angles, then using the sum of interior angles and the current known interior angles you can find the last known interior angle. If they are asking you to solve for an exterior angle, you can once again subtract the known interior angle from 180 degrees to find the exterior angle.
For the second page, you can refer to exterior angles again. Knowing that all exterior angles add to 360 degrees, and since we are given all of them, we can set the sum of the exterior angles to 360 degrees.
9x + 4x + (5x + 10) + (5x + 25) = 360
