Find F'(x): F(x) = Sx 3 t^1/3 dt
The derivative of F(x) is \(F'(x) = x^{(1/3)\).
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
To find the derivative of the given function F(x), we will apply the fundamental theorem of calculus and differentiate the integral with respect to x.
Let's compute F'(x):
F(x) = ∫[0 to x] \(t^{(1/3)} dt\)
To differentiate the integral with respect to x, we'll use the Leibniz integral rule:
F'(x) = d/dx ∫[0 to x] \(t^{(1/3)} dt\)
According to the Leibniz integral rule, we have to apply the chain rule to the upper limit of the integral.
\(F'(x) = x^{(1/3)} d(x)/dx - 0^{(1/3)} d(0)/dx\) [applying the chain rule to the upper limit]
Since the upper limit of the integral is x, the derivative of x with respect to x is 1, and the derivative of 0 with respect to x is 0.
\(F'(x) = x^{(1/3)} (1) - 0^{(1/3)} (0)\)
\(F'(x) = x^{(1/3)\)
Therefore, the derivative of F(x) is \(F'(x) = x^{(1/3)\).

Shellac O'Lean, a freshman on your school's football team, is 6 ft tall and weighs 140 lb. Since he would rather play basketball, he plans to grow to 7 ft 1 in., the same height as Shaquille O'Neal, his idol. If Shellac scales geometrically as he grows, how much can he expect to weigh? (O'Neal weighs 325 lb. Round your answer to the nearest whole number.)
Answer:
At 7 ft. 1 in., Shellac can expect to weigh approximately 165 lb
Step-by-step explanation:
The relationship between the heights and the weights of the freshman are presented as follows;
The weight of the freshman at 6 ft. = 140 lb
The height to which he plans to grow = 7 ft. 1 in.
Given that Shellac scales geometrically as he grows, then the height to weight ratio is constant
Let 'y' represent Shellac's weight when his height is 75 ft. 1 in., we have;
\(\dfrac{6 \, ft.}{140 \ lb} = \dfrac{7 \, ft. \ 1 \, in. }{y}\)
6 ft. = 72 in.
7 ft. 1 in. = 85 in.
Therefore, we get;
\(\dfrac{72 \ in.}{140 \ lb} = \dfrac{85 \ in. }{y}\)
\(y ={85 \ in. }\times \dfrac{140 \, lb}{72 \ in.} = 165.2 \overline 7 \, lbs\)
Shellac's expected weight given to the nearest whole number when his height is 7 ft. 1 in. ≈ 165 lb.

How to solve the given equation?In order to open the bracket and isolate the variable x, we would first of all multiply both sides by 5/2 as follows:
2/5(5 + x) = 8
Multiplying both sides by 5/2, we have:
5/2 × 2/5(5 + x) = 8 × 5/2
5 + x = 40/2
5 + x = 20
Subtracting 5 from both sides, we have:
5 + x - 5 = 20 - 5
x = 15
Method 2.In order to open the bracket and isolate the variable x, we would first of all multiply both sides by 1/2 and then 5 as follows:
2/5(5 + x) = 8
Multiplying both sides by 1/2, we have:
1/2 × 2/5(5 + x) = 8 × 1/2
1/5(5 + x) = 4
Multiplying both sides by 5, we have:
5 × 1/5(5 + x) = 4 × 5
5 + x = 20
Subtracting 5 from both sides, we have:
5 + x - 5 = 20 - 5
x = 15
Method 3.In order to open the bracket and isolate the variable x, we would apply the distributive property of multiplication:
2/5(5 + x) = 8
2/5 × 5 + 2/5 × x = 8
2 + 2x/5 = 8
Subtracting 2 from both sides, we have:
2 - 2 + 2x/5 = 8 - 2
2x/5 = 6
Multiplying both sides by 5/2, we have:
5/2 × 2x/5 = 5/2 × 6
x = 30/2
x = 15.

For the linear equations provided by the coordinates in the table;
The first equation of this system is y = -2x.
The second equation of this system is y = x - 3.
The solution to the system is (1, -2).
How do we solve for the system of linear equation?We have four points (-5,10), (-1,2), (0,0), and (11,-22) for first equation, and four points (-8,-11), (-2,-5), (1,-2), and (7,4) the second equation.
The slope (m) is given by the formula (y2 - y1) / (x2 - x1).
For the first line, we can use the points (-5,10) and (-1,2)
m1 = (2 - 10) / (-1 - (-5)) = -8/4 = -2.
the first equation is y = -2x
the second line, we can use the points (-8,-11) and (-2,-5)
m2 = (-5 - -11) / (-2 - -8) = 6/6 = 1.
the second line has a slope of 1,
the equation should have the form y = x + c.
To find c, we can use one of the points, for instance (-2,-5):
-5 = -2 + c => c = -5 + 2 = -3.
So, the second equation is y = x - 3.
the solution to the system, we need to find where the two lines intersect.
y = -2x
y = x - 3
Setting both equation equally
-2x = x - 3
=> 3x = 3
=> x = 1.
Substituting x = 1 into the first equation
y = -2(1) = -2.
the solution to the system of linear equation would be (1, -2).

Ema substituted the measurements of her cone into the formula to find the surface area. Her work is shown below. SA = π(142) + π(14)(29) What can be concluded from Ema's equation? Check all that apply. The slant height of the cone is 14 units. The diameter of the cone is 28 units. The base area of the cone is 196Piunits2. The lateral area is the product of pi, the radius, and the slant height. The surface area is 434Pi units2.
Answer:
B, C and D
Step-by-step explanation:
Ema found the surface area of a cone as:
\(S.A = \pi(14^2) + \pi(14)(29)\)
Surface Area of a Cone \(S.A.=\pi r^2+\pi rl\)
Therefore:
Radius, r =14 units
Slant Height, l = 29 Units
(B)The diameter of the cone is 28 units.
SInce Diameter =Radius X 2
Diameter = 14 X 2= 28 Units
(C)The base area of the cone is \(196\pi$ units^2.\)
Base Area of a Cone \(=\pi r^2\)
Since r=14 Units
Base Area = \(=\pi 14^2=196\pi $ square units\)
(D)The lateral area is the product of pi, the radius(r), and the slant height(l).

Answer:
The similarity postulate theorem is;

The following cone has a slant height of 17

cm.
What is the volume of the cone?
Responses
480π
320π
544π
The formula for the volume of a cone is:
V = (1/3)πr²h
where r is the radius of the base, h is the height of the cone, and π is pi.
In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:
h² = s² - r²
h² = 17² - 8²
h² = 225
h = 15
Now that we have the height, we can plug in the values for r and h into the formula for the volume:
V = (1/3)π(8²)(15)
V = (1/3)π(64)(15)
V = (1/3)(960π)
V = 320π
Therefore, the volume of the cone is 320π cubic cm. Answer: 320π.

D.They do not, just calculate them with the data the same as all the other data. PLEASE HELPPP!!!!!!
Answer:
A.They may significantly affect the mean of the data.
Step-by-step explanation:
The outliers may significantly affect the mean of the data.
What is outlier?The extreme values in the data are called outliers.
Example: For a data set containing 2, 19, 25, 32, 36, 38, 31, 42, 57, 45, and 84.
In the above number line, we can observe the numbers 2 and 84 are at the extremes and are thus the outliers.
The outliers are a part of the group but are far away from the other members of the group.
For example:
Consider the data: 70, 73, 77, 71, 7, 73, 72, and 78
Let's calculate the mean to understand how the outlier affects the results.
Here, the datapoint 7, is an outlier.
Mean (with outlier)
=70+73+77+71+7+73+72+78/8
=521/8
=65.1
Mean (without an outlier) = 70+73+77+71+73+72+78/7 = 514/ 7 =73.4.
the outlier creates a variation in the mean value of the data.
As, from the example discussed above we have seen that outliers depends on mean of the data.
Hence, outliers may significantly affect the mean of the data.

SNNNDNDNND==========================================================
Explanation:
Question 1
27x^6 = (3x^2)^3 which is one cube and y^3 is another cube
Therefore 27x^6+y^3 is a sum of two cubes.
It might help to think of it like A^3+B^3 where in this case A = 3x^2 and B = y.
----------------------------------------
Question 2
81 isn't a perfect cube since 81^(1/3) = 4.3267 approximately, which isn't a whole number. We need 81^(1/3) to be a whole number if we wanted 81 to be a perfect cube.
We don't even need to check b^15 since 81 being a non-perfect cube means the entire expression cannot be a sum of two cubes, nor a difference of cubes.
----------------------------------------
Question 3
64x^3 = (4x)^3 is a perfect cube
but 9z^9 is not a perfect cube
We can see this if we computed 9^(1/3) and the result is a non-whole number.
The answer here is the same as the previous question.
----------------------------------------
Question 4
36^(1/3) is not a whole number, so 36 isn't a perfect cube. By extension 36m^12 isn't a perfect cube either. The answer is the same as questions 2 and 3.
----------------------------------------
Question 5
1 is a perfect cube since 1 = 1^3
d^12 is a perfect cube because d^12 = (d^4)^3
Therefore, we have a difference of two cubes.
----------------------------------------
Question 6
729^(1/3) = 9 which rearranges to 9^3 = 729, showing 729 is a perfect cube.
However y^29 is not a perfect cube since the exponent 29 is not a multiple of 3.
The overall expression is "neither".
----------------------------------------
Question 7
343^(1/3) = 7 rearranges to 7^3 = 343, showing 343 is a perfect cube
y^6 is a perfect cube since (y^2)^3, i.e. the exponent 6 is a multiple of 3.
We have a difference of cubes.
----------------------------------------
Question 8
4 isn't a perfect cube since 4^(1/3) results in some decimal value that isn't a whole number. The entire expression is neither a sum nor difference of cubes.
----------------------------------------
Question 9
144^(1/3) isn't a whole number, so we get a similar result to problem 8.
----------------------------------------
Question 10
64j^6 = (4j^3)^3 is one cube
k^9 = (k^3)^3 is another cube
We have a difference of cubes

The triangle is scalene: A scalene triangle is a triangle with three unequal side lengths. Since no information is provided about the side lengths of triangle LMN, determine if it is scalene. Thus, it cannot be confirmed as true.
The triangle is equilateral: An equilateral triangle is a triangle with three equal side lengths. Without any information about the side lengths of triangle LMN, determine if it is equilateral. Thus, it cannot be confirmed as true.
The triangle is isosceles: An isosceles triangle is a triangle with at least two equal side lengths. Without any information about the side lengths of triangle LMN, determine if it is isosceles. Thus, it cannot be confirmed as true.
The triangle is a right triangle: A right triangle is a triangle with one right angle (90 degrees). No information is given about the angles of triangle LMN, so determine if it has a right angle. Thus, it cannot be confirmed as true.

Solve the system of equations. 2y + 77 = -5 5y – 7x = 12 72
Answer:
\(y=-41,\:x=-211\)
Step-by-step explanation:
\(\begin{bmatrix}2y+77=-5\\ 5y-7x=1272\end{bmatrix}\)
Isolate y for 2y+77=-5:
\(y=-41\)
\(\mathrm{Substitute\:}y=-41\)
\(\begin{bmatrix}5\left(-41\right)-7x=1272\end{bmatrix}\)
\(Simplify\)
\(\begin{bmatrix}-205-7x=1272\end{bmatrix}\)
Isolate x for -205-7x=1272
\(x=-211\)
\(\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}\)
\(y=-41,\:x=-211\)
