There are 792 ways to distribute 8 indistinguishable balls into 5 distinguishable bins. There are 9 ways to distribute 8 indistinguishable balls into 5 indistinguishable bins.
(a) When distributing 8 indistinguishable balls into 5 distinguishable bins, we can use the concept of stars and bars. We can imagine the balls as stars and the bins as bars. To separate the balls into different bins, we need to place the bars in between the stars. The number of ways to distribute the balls is equivalent to finding the number of ways to arrange the stars and bars, which is given by the formula (n + k - 1) choose (k - 1), where n is the number of balls and k is the number of bins. In this case, we have (8 + 5 - 1) choose (5 - 1) = 792 ways.
(b) When distributing 8 indistinguishable balls into 5 indistinguishable bins, we can use a technique called partitioning. We need to find all the possible ways to partition the number 8 into 5 parts. Since the bins are indistinguishable, the order of the partitions does not matter. The possible partitions are {1, 1, 1, 1, 4},

c) f(x, y, z) = xyz, (x0, y0, z0) = (1, 0, 1), d = (1, 0, −1)
a) The directional derivative of f(x, y) = xy along the unit vector d = 5i + 12j at the point (x0, y0) = (e, e) is 17e.
b) The directional derivative of f(x, y, z) = ex + yz along the unit vector d = (4, −3, 3) at the point (x0, y0, z0) = (1, 1, 1) is 1.
c) The directional derivative of f(x, y, z) = xyz along the unit vector d = (1, 0, −1) at the point (x0, y0, z0) = (1, 0, 1) is 0.
The directional derivative measures the rate at which a function changes along a specified direction. It is computed by taking the dot product of the gradient of the function with the unit vector representing the direction.
For part (a), the gradient of f(x, y) = xy is (∂f/∂x, ∂f/∂y) = (y, x), and at the point (e, e), it becomes (e, e). Taking the dot product of this gradient with the unit vector (5, 12) gives 5e + 12e = 17e.
For part (b), the gradient of f(x, y, z) = ex + yz is (∂f/∂x, ∂f/∂y, ∂f/∂z) = (e, z, y), and at the point (1, 1, 1), it becomes (e, 1, 1). Taking the dot product of this gradient with the unit vector (4, -3, 3) gives 4e - 3 + 3 = 1.
For part (c), the gradient of f(x, y, z) = xyz is (∂f/∂x, ∂f/∂y, ∂f/∂z) = (yz, xz, xy), and at the point (1, 0, 1), it becomes (0, 0, 0). Taking the dot product of this gradient with the unit vector (1, 0, -1) gives 0.

The directional derivative of the function f(x, y, z) = yz + x^4 at the point (2, 3, 1) in the direction of a vector making an angle of 2π/3 with ∇f(2, 3, 1) can be found using the dot product of the gradient vector
First, we calculate the gradient of f(x, y, z) at the point (2, 3, 1) by finding the partial derivatives with respect to x, y, and z. The gradient vector, denoted by ∇f(2, 3, 1), represents the direction of the steepest ascent at that point.
Next, we determine the unit vector in the direction specified, which is obtained by dividing the given vector by its magnitude. This unit vector will have the same direction but a magnitude of 1.
Taking the dot product of the gradient vector and the unit vector gives the directional derivative. This product measures the rate of change of the function f(x, y, z) in the specified direction. The numerical value of the directional derivative can be calculated by substituting the values of the gradient vector, unit vector, and point (2, 3, 1) into the dot product formula. This provides the rate of change of the function at the given point in the given direction.

Use the Divergence Theorem to find the flux of the vector field i = iy+ (2xy + 22) + k2yz and a unit cube at the origin + Select one: 2 3 4 None of them
w333The Divergence Theorem is a critical vector calculus result that is used to determine the flow of a vector field through a surface. A unit cube is a three-dimensional object with edges of length 1 unit. The divergence of a vector field describes how quickly the field's values are changing at a particular point in space.
It is represented by the operator div.According to the Divergence Theorem, the flux of a vector field through a surface is equal to the divergence of the field over the enclosed volume.Here's the solution to the given problem:Given that the vector field is,i = iy + (2xy + 22) + k2yzThe divergence of the vector field is:div(i) = (∂/∂x) . i + (∂/∂y) . j + (∂/∂z) . k(2xy + 22) + 0 + 2yz= 2xy + 2yz + 22Therefore, the flux of the vector field through the unit cube can be calculated as follows:flux = ∫∫S i.dS= ∫∫S i.n dSwhere S is the surface area, n is the normal unit vector, and i.n is the dot product of i and n. Since the unit cube is centered at the origin and is symmetric, the flux through each face is the same, and the sum of the flux through each face is zero. Hence, the flux through one face of the cube can be computed as follows:flux = ∫∫S i.n dS= ∫∫S i.n dS= ∫∫S i.y dxdz= ∫_0^1 ∫_0^1 y dydz= ∫_0^1 dz= 1Therefore, the flux of the vector field through the unit cube at the origin is 1.

Given the functions g(x), h(x), and y-values, we can find the x-values using the information provided. By plugging in the y-values into h(x) we get the corresponding x-values.
Once we have the x-values, we can plug them into g(x) to get the corresponding values of f(x).
Using f(x) = g(h(x)), we can find the values of f(x) for each of the x-values given. With these values, we can find the derivative of f(x) at x = 1, denoted by f'(1). This is the value we are asked to find.
To do so, we need to find the derivatives of g(x) and h(x) and then plug in the appropriate values. Once we have these values, we can use the chain rule to find the derivative of f(x) with respect to x.
The final step is to plug in x = 1 and evaluate f'(1). The expression for f'(1) will be in terms of the derivatives of g(x) and h(x), evaluated at the corresponding x-values.

In an acute-angled triangle AABC with sides AB, AC, and BC, it is possible to construct a square PQRS such that P lies on AB, Q and R lie on BC, and S lies on AC. triangle. The height is 89.33.
Let's consider triangle AABC. Since it is an acute-angled triangle, all three angles of the triangle are less than 90 degrees. To construct a square PQRS, we start by drawing a perpendicular from A to BC, meeting BC at point Q. Next, we draw a perpendicular from C to AB, meeting AB at point P. The point where these perpendiculars intersect is the fourth vertex of the square, S. Since the angles of triangle AABC are acute, the perpendiculars intersect within the triangle, ensuring that the square lies entirely within the triangle.
To determine the side length of square PQRS, we use the given side lengths of the triangle. The area of triangle AABC is given as 490√3. We know that the area of a triangle can be calculated as (base * height) / 2. In this case, the base of the triangle can be taken as BC, and the height can be taken as the distance between A and BC, which is the same as the side length of the square. By substituting the given values, we have (19 * height) / 2 = 490√3.

To find the interval(s) of continuity for the function f(x) = (x + 3)^2 + 9, we need to consider the domain of the function and check for any points where the function may be discontinuous.
The given function f(x) = (x + 3)^2 + 9 is a polynomial function, and polynomials are continuous for all real numbers. Therefore, the function f(x) is continuous for all real numbers. Since there are no restrictions or excluded values in the domain of the function, we can conclude that the interval of continuity for the function f(x) = (x + 3)^2 + 9 is (-∞, ∞), meaning it is continuous for all values of x. The function f(x) = (x + 3)^2 + 9 is a quadratic function. Let's analyze its properties. Domain: The function is defined for all real numbers since there are no restrictions or excluded values in the expression (x + 3)^2 + 9. Therefore, the domain of f(x) is (-∞, ∞). Range: The expression (x + 3)^2 + 9 represents a sum of squares and a constant. Since squares are always non-negative, the smallest possible value for (x + 3)^2 is 0 when x = -3. Adding 9 to this minimum value, the range of f(x) is [9, ∞).

2) Evaluate ſa arcsin x dx by using suitable technique of integration.
To evaluate the integral ∫√(1 - [tex]x^{2}[/tex]) dx, where -1 ≤ x ≤ 1, we can use the trigonometric substitution technique. We get the result (1/2) θ + (1/4) sin 2θ + C where C is the constant of integration.
By substituting x = sinθ, the integral can be transformed into ∫[tex]cos^2[/tex]θ dθ. The integral of [tex]cos^2[/tex]θ can then be evaluated using the half-angle formula and integration properties, resulting in the answer.
To evaluate the given integral, we can employ the trigonometric substitution technique. Let's substitute x = sinθ, where -π/2 ≤ θ ≤ π/2. This substitution helps us simplify the integral by replacing the square root term √(1 - [tex]x^{2}[/tex]) with √(1 - [tex]sin^2[/tex]θ), which simplifies to cosθ.
Next, we need to express the differential dx in terms of dθ. Differentiating both sides of x = sinθ with respect to θ gives us dx = cosθ dθ.
Substituting x = sinθ and dx = cosθ dθ into the integral, we obtain:
∫√(1 - [tex]x^2[/tex]) dx = ∫√(1 - [tex]sin^2[/tex]θ) cosθ dθ.
Simplifying the expression inside the integral gives us:
∫[tex]cos^2[/tex]θ dθ.
Now, we can use the half-angle formula for cosine, which states that [tex]cos^2[/tex]θ = (1 + cos 2θ)/2. Applying this formula, the integral becomes:
∫(1 + cos 2θ)/2 dθ.
Splitting the integral into two parts, we have:
(1/2) ∫dθ + (1/2) ∫cos 2θ dθ.
The first integral ∫dθ is simply θ, and the second integral ∫cos 2θ dθ can be evaluated to (1/2) sin 2θ using standard integration techniques.
Finally, substituting back θ = arcsin x, we get the result:
(1/2) θ + (1/4) sin 2θ + C,

The average value of the function f(x, y) = 3 over the given rectangle R = {(-15 ≤ x ≤ 54, 25 ≤ y ≤ 56)} is 3.
To find the average value of a function over a given rectangle, we need to calculate the integral of the function over the rectangle and divide it by the area of the rectangle. In this case, the function f(x, y) = 3, which means the value of the function is constant at 3 throughout the entire rectangle.
The integral of a constant function is equal to the value of the constant times the area of the region. In our case, the area of the rectangle R is (54 - (-15)) * (56 - 25) = 69 * 31 = 2139. Therefore, the integral of the function over the rectangle is 3 * 2139 = 6417.
Next, we divide the integral by the area of the rectangle to find the average value. So, the average value of the function f(x, y) = 3 over the rectangle R is 6417 / 2139 = 3.

Bernard can use the equation h = (220 - (3.5 * 40))/40 to predict how many hours they will drive in the afternoon.
In this equation, h represents the number of hours they will drive in the afternoon, 220 is the total distance to the park, 3.5 is the duration of the morning drive in hours, and 40 is the average speed in miles per hour.
In the first paragraph, we summarize that Bernard can use the equation h = (220 - (3.5 * 40))/40 to predict the number of hours they will drive in the afternoon. This equation takes into account the total distance to the park, the duration of the morning drive, and the average speed. In the second paragraph, we explain the components of the equation. The numerator, (220 - (3.5 * 40)), represents the remaining distance to be covered after the morning drive, which is 220 miles minus the distance covered in the morning (3.5 hours * 40 miles per hour). The denominator, 40, represents the average speed at which they expect to drive. By dividing the remaining distance by the average speed, Bernard can calculate the number of hours they will drive in the afternoon to complete the trip to the Gold Coast State Park.

Answer: Limit Comparison Test is inconclusive for this series.
Step-by-step explanation: To compare the given series using the Limit Comparison Test, we need to determine which series (A, B, or C) to compare them with and whether they converge or diverge. Let's analyze each series individually:
1. ∑(n=1 to ∞) (17n^2 + 4n + n^3) / (5617n^3 + 7n + 3)
To apply the Limit Comparison Test, we need to choose a series to compare it with. Let's compare it with series A.
Series A: ∑(n=1 to ∞) 1/n^2
Taking the limit of the ratio of the given series to series A as n approaches infinity:
lim (n→∞) [(17n^2 + 4n + n^3) / (5617n^3 + 7n + 3)] / (1/n^2)
lim (n→∞) [(17n^2 + 4n + n^3) / (5617n^3 + 7n + 3)] * (n^2/1)
lim (n→∞) [(17 + 4/n + 1/n^2) / (5617 + 7/n^2 + 3/n^3)]
lim (n→∞) [17/n^2 + 4/n^3 + 1/n^4] / [5617/n^3 + 7/n^4 + 3/n^5]
0 / 0 (indeterminate form)
Since we have an indeterminate form, we can simplify the expression further by dividing every term by n^5:
lim (n→∞) [17/n^7 + 4/n^8 + 1/n^9] / [5617/n^8 + 7/n^9 + 3/n^10]
0 / 0 (still an indeterminate form)
To determine the limit, we can apply L'Hôpital's Rule by taking the derivatives of the numerator and denominator successively until we obtain a determinate form:
lim (n→∞) [0 + 0 + 0] / [0 + 0 + 0]
lim (n→∞) 0 / 0 (still an indeterminate form)
Applying L'Hôpital's Rule once more:
lim (n→∞) [0 + 0 + 0] / [0 + 0 + 0]
lim (n→∞) 0 / 0 (still an indeterminate form)
After several applications of L'Hôpital's Rule, we still have an indeterminate form. This means the Limit Comparison Test is inconclusive for this series.
Therefore, we cannot determine whether the series converges or diverges by using the Limit Comparison Test with series A.

(a) To evaluate the definite integral of (tan x)/(1 + tan^2 x) with respect to x from 0 to π/4, we can make the substitution u = tan x.
When u = tan x, the differential dx can be expressed as du/(1 + u^2).
The new integral becomes ∫[0 to 1] du/(1 + u^2).
This is a standard integral of the form ∫(1/(1 + x^2)) dx, which we can evaluate by taking the inverse tangent function:
∫(1/(1 + u^2)) du = arctan(u) + C.
Evaluating the definite integral from 0 to 1, we have arctan(1) - arctan(0) = π/4 - 0 = π/4.
Therefore, the value of the definite integral is π/4.
(b) To evaluate the definite integral of √(2 - x^2) dx, we recognize that this represents the upper half of a circle with radius √2 centered at the origin.
The area of a half-circle with radius r is (1/2)πr^2. In this case, r = √2.
Thus, the area of the upper half-circle is (1/2)π(√2)^2 = (1/2)π(2) = π.

What are complex numbers?
Complex numbers provide a way to extend the number system to include solutions to equations that do not have real number solutions. They are widely used in mathematics, engineering, physics, and various other fields.
Let [tex]z = 3 + 4i$ and $w = a + bi$,[/tex] where [tex]a, b \in \mathbb{R}$.[/tex]
(a) To find the value of b such that zw is real, we multiply z and w and equate the imaginary part to zero:
[tex]\[\text{Im}(zw) = \text{Im}(z) \cdot \text{Im}(w) = 4b = 0\][/tex]
Since the imaginary part is zero, we have b = 0. Therefore, w = a.
(b) To determine [tex]\text{arg}(z - 7)$,[/tex] we subtract 7 from z and calculate the argument:
[tex]\[\text{arg}(z - 7) = \text{arg}(3 + 4i - 7) = \text{arg}(-4 + 4i)\][/tex]
The argument of a complex number can be found using the arctangent function:
[tex]\[\text{arg}(-4 + 4i) = \arctan\left(\frac{\text{Im}(-4 + 4i)}{\text{Re}(-4 + 4i)}\right) = \arctan\left(\frac{4}{-4}\right) = \arctan(-1) = -\frac{\pi}{4}\][/tex]

(8 points) Consider the vector field F (2, y, z) = (2+y)i + (32+2)j + (3y+z)k. a) Find a function f such that F= Vf and f(0,0,0) = 0. f(2, y, z) = b) Suppose C is any curve from (0,0,0) to (1,1,1). Us
h(z) = 0. Thus, the function[tex]f(x, y, z) is: f(x, y, z) = 2x + 3xy + 2y[/tex]. Now, for part (b) of your question, you mentioned C as a curve from (0,0,0) to (1,1,1).
To find the function f such that[tex]F = ∇f and f(0,0,0) = 0[/tex], we need to determine the potential function f(x, y, z) for the given vector field F.
Given: [tex]F(x, y, z) = (2+y)i + (3x+2)j + (3y+z)k[/tex]
To find f, we integrate each component of F with respect to its corresponding variable:
[tex]∂f/∂x = 2+y∂f/∂y = 3x+2∂f/∂z = 3y+z[/tex]
Integrating the first equation with respect to x while treating y and z as constants:
[tex]f(x, y, z) = 2x + xy + g(y, z)[/tex]
Here, g(y, z) is an arbitrary function of y and z that represents the constant of integration.
Taking the partial derivative of f(x, y, z) with respect to y:
[tex]∂f/∂y = x + ∂g/∂y[/tex]
Comparing this to the second equation of F, we have:
[tex]x + ∂g/∂y = 3x+2[/tex]
From this, we can deduce that ∂g/∂y = 2x+2.
Integrating the above equation with respect to y while treating z as a constant:
[tex]g(y, z) = 2xy + 2y + h(z)[/tex]
Here, h(z) is an arbitrary function of z that represents the constant of integration.
Now, substituting g(y, z) and f(x, y, z) back into the initial equation:
[tex]f(x, y, z) = 2x + xy + 2xy + 2y + h(z)[/tex]
Simplifying, we get:
[tex]f(x, y, z) = 2x + 3xy + 2y + h(z)[/tex]
Finally, since f(0,0,0) = 0, we can determine the value of[tex]h(z):f(0, 0, z) = 2(0) + 3(0)(0) + 2(0) + h(z) = 0[/tex]

find the exact values of the six trigonometric functions of angle 0, if 9.-3 is a terminal point
The exact values of the six trigonometric functions of angle 0, with a terminal point at (9, -3), are as follows: sine (sin) = -3/9 = -1/3, cosine (cos) = 9/9 = 1, tangent (tan) = -3/9 = -1/3, cosecant (csc) = -3/(-3) = 1, secant (sec) = 9/9 = 1, and cotangent (cot) = 9/-3 = -3.
To find the values of the trigonometric functions for an angle with a terminal point, we need to determine the ratios of the sides of a right triangle formed by the angle and the x and y coordinates of the terminal point. In this case, the x-coordinate is 9 and the y-coordinate is -3.
The sine (sin) of an angle is defined as the ratio of the length of the side opposite the angle to the hypotenuse. In this case, the opposite side is -3 and the hypotenuse can be calculated using the Pythagorean theorem as √(9^2 + (-3)^2) = √90. Therefore, sin(0) = -3/√90 = -1/3.
The cosine (cos) of an angle is defined as the ratio of the length of the side adjacent to the angle to the hypotenuse. In this case, the adjacent side is 9, and the hypotenuse is √90. Therefore, cos(0) = 9/√90 = 1.
The tangent (tan) of an angle is defined as the ratio of the sine of the angle to the cosine of the angle. Therefore, tan(0) = sin(0)/cos(0) = (-1/3) / 1 = -1/3.
The cosecant (csc) of an angle is the reciprocal of the sine of the angle. Therefore, csc(0) = 1/sin(0) = 1 / (-1/3) = -3.
The secant (sec) of an angle is the reciprocal of the cosine of the angle. Therefore, sec(0) = 1/cos(0) = 1/1 = 1.
The cotangent (cot) of an angle is the reciprocal of the tangent of the angle. Therefore, cot(0) = 1/tan(0) = 1 / (-1/3) = -3.
In summary, the values of the trigonometric functions for angle 0, with a terminal point at (9, -3), are sin(0) = -1/3, cos(0) = 1, tan(0) = -1/3, csc(0) = -3, sec(0) = 1, and cot(0) = -3.

find the missing terms of the sequence and determine if the sequence is arithmetic, geometric, or neither. 252,126,63,63/2, ____ , _____.
The missing terms of the sequence are 15.75 and 7.875, and the sequence is geometric.
What is sequence?
In mathematics, a sequence is an ordered list of numbers or objects in a specific pattern or order. Each individual element in the sequence is called a term or member of the sequence.
To determine the missing terms of the sequence and determine its pattern (whether arithmetic, geometric, or neither), let's examine the given sequence: 252, 126, 63, 63/2, __, __.
First, let's check if the sequence has a common difference between consecutive terms to determine if it is an arithmetic sequence. We'll calculate the differences between consecutive terms:
Difference between the 2nd and 1st terms: 126 - 252 = -126
Difference between the 3rd and 2nd terms: 63 - 126 = -63
Difference between the 4th and 3rd terms: (63/2) - 63 = -63/2
The differences are not constant, so the sequence is not arithmetic.
Next, let's check if the sequence has a common ratio between consecutive terms to determine if it is a geometric sequence. We'll calculate the ratios between consecutive terms:
Ratio between the 2nd and 1st terms: 126/252 = 1/2
Ratio between the 3rd and 2nd terms: 63/126 = 1/2
Ratio between the 4th and 3rd terms: (63/2) / 63 = 1/2
The ratios are constant (1/2), so the sequence is geometric.
Since the sequence is geometric with a common ratio of 1/2, we can use this ratio to find the missing terms.
To find the next term, we multiply the previous term by the common ratio:
(63/2) * (1/2) = 63/4 = 15.75
To find the term after that, we multiply the previous term by the common ratio again:
(63/4) * (1/2) = 63/8 = 7.875
Therefore, the missing terms of the sequence are 15.75 and 7.875.
In summary, the missing terms of the sequence are 15.75 and 7.875, and the sequence is geometric.

b) cos^(-1)(-√3/2) = 5π/6 or 150 degrees.
c) tan^(-1)(-∞) = -π/2 or -90 degrees.
To find the values of sin(2α), cos(2α), and tan(2α), we can use the double angle formulas. Given that sin(α) = -4/5 and α is in quadrant III, we can determine the values as follows: sin(2α): sin(2α) = 2sin(α)cos(α)
Since sin(α) = -4/5, we need to find cos(α).
In quadrant III, sin(α) is negative, and we can use the Pythagorean identity to find cos(α):
cos(α) = -√(1 - sin^2(α)) = -√(1 - (16/25)) = -√(9/25) = -3/5
Now, we can substitute the values: sin(2α) = 2*(-4/5)*(-3/5) = 24/25
cos(2α):
cos(2α) = cos^2(α) - sin^2(α)
Using the values we obtained earlier:
cos(2α) = (-3/5)^2 - (-4/5)^2 = 9/25 - 16/25 = -7/25
tan(2α):
tan(2α) = sin(2α)/cos(2α)
Substituting the values we found:
tan(2α) = (24/25)/(-7/25) = -24/7
Now, let's find the exact values of the given inverse trigonometric functions:
a) sin^(-1)(-1/2):
sin^(-1)(-1/2) is the angle whose sine is -1/2. It corresponds to -π/6 or -30 degrees.
b) cos^(-1)(-√3/2):
cos^(-1)(-√3/2) is the angle whose cosine is -√3/2. It corresponds to 5π/6 or 150 degrees.

Determine the equation of the tangent to the curve y=(5(square root
of x))/x at x=4
3) Determine the equation of the tangent to the curve y=0 5x at x = 4 - y = X y = 5tx Х
To determine the equation of the tangent to a curve at a specific point, we need to find the slope of the tangent at that point and use it along with the coordinates of the point to form the equation of the line. In the first case, the curve is given by y = (5√x)/x, and we find the slope of the tangent at x = 4. In the second case, the curve is y = 5tx^2, and we find the equation of the tangent at x = 4 and y = 0.
For the curve y = (5√x)/x, we need to find the slope of the tangent at x = 4. To do this, we first differentiate the equation with respect to x to obtain dy/dx. Applying the quotient rule and simplifying, we find dy/dx = (5 - 5/2x)/x^(3/2). Evaluating this derivative at x = 4, we get dy/dx = (5 - 5/8)/(4^(3/2)) = (35/8)/(4√2) = 35/(8√2). This slope represents the slope of the tangent at x = 4. Using the point-slope form of the equation of a line, y - y₁ = m(x - x₁), we substitute the coordinates (4, (5√4)/4) and the slope 35/(8√2) to obtain the equation of the tangent.
For the curve y = 5tx^2, we are given that y = 0 at x = 4. At this point, the tangent line will be horizontal (with a slope of 0) since the curve intersects the x-axis. Thus, the equation of the tangent will be y = 0, which means it is a horizontal line passing through the point (4, 0).

Suppose that 3 1 of work is needed to stretch a spring from its natural length of 34 cm to a length of 50 cm. (a) How much work is needed to stretch the spring from 38 cm to 46 cm? (Round your answer
To determine the work needed to stretch the spring from 38 cm to 46 cm, we can use the concept of elastic potential energy.
The elastic potential energy stored in a spring is given by the equation:
Potential energy = (1/2)kx^2
where k is the spring constant and x is the displacement from the equilibrium position.
Given that 31 J of work is needed to stretch the spring from 34 cm to 50 cm, we can find the spring constant (k) using the formula:
Potential energy = (1/2)kx^2
31 J = (1/2)k(50 cm - 34 cm)^2
Simplifying the equation:
31 J = (1/2)k(16 cm)^2
31 J = (1/2)k(256 cm^2)
