The dimensions of the tank with minimum  weight  is height= 7 and width and length= 14.

The minimum surface area implies that the tank has minimum weight.

Given that the base is square, its width is equal to its length.

Let x= the base width and length of the tank.

Let h = the height .

We are given the volume of the tank that is 1372 ft^3. The formula is given by

V = hx^2

We're given that V = 1,372 ft^3, so

hx^2 = 1,372

h = 1,372 / x^2  ----------(equation 1)

Surface area can be calculated using the below given formula.

A = x^2 + 4xh

Substituting the value of euation 1, h in A, we get,

A = x^2 + 4x(1,372 / x^2)

= x^2 + 5,488 / x

To get the minimum surface area to get the minimum weight, we need to differentiate  A with respect to x and equate it to zero.

dA/dx = 2x - 5,488 / x^2 = 0

2x^3 - 5,488 = 0

x =\(\sqrt[3]{\frac{5,488}{2} }\)

x= 14

We got the value of x, we substitute the value in equation 1, we get the value of h.

h = 1,372 / 14^2

h= 7

So, the dimensions of the tank with minimum weight are width and length is 14 and height is 7.

Step-by-step explanation:

If |q| = 5 at an angle of 45° and |r| = 16 at an angle of 300°. then the

|q – r| will be 18.0

To find |q - r|, we need to subtract the complex numbers q and r after which discover the magnitude (or absolute value) of the end result.

First, we want to express q and r in rectangular form, which means that finding their actual and imaginary additives:

For q, we've:

|q| = 5 at an perspective of 45°

Re(q) = |q| cos(45°) = five cos(45°) = 5/√2

Im(q) = |q| sin(45°) = 5 sin(45°) = 5/√2

So q = (5/√2) + (5/√2)i

For r, we have:

|r| = 16 at an angle of 300°

Re(r) = |r| cos(300°) = 16 cos(300°) = sixteen(-√3/2) = -8√three

Im(r) = |r| sin(300°) = 16 sin(300°) = -8

So r = -8√three - 8i

Now we are able to discover q - r by using subtracting the actual and imaginary additives:

q - r = (5/√2) + (5/√2)i - (-8√3 - 8i)

= (5/√2) + 8√3 + (5/√2 + 8)i

To discover |q - r|, we want to take the importance of this complex number:

|q - r| = √[(5/√2 + 8√3)² + (5/√2 + 8)²]

= √[25/2 + 80√3 + 192 + 50/2 + 40 + 64]

= √[125/2 + 80√3 + 256]

= √[625/4 + 320√3 + 1024]

= √[(25/2 + 16√3)²]

= 25/2 + 16√3

≈ 18.0

Hence, |q - r| is about equal to 18.0.

Explanation:

The interval of t-values such that c(t)=(cost,sint) traces the upper half of the unit circle (in the counter-clockwise direction) is  [π/2, 3π/2].

To trace the upper half of the unit circle in the counter-clockwise direction, we need the y-coordinate (sint) of the curve to be positive. Since sin is positive in the first and second quadrants of the unit circle, we need to find the interval of t-values such that cos(t) is within the b [-1, 1] of the x-coordinate in the first and second quadrants. This interval will correspond to the portion of the unit circle in which the curve c(t) lies on the upper half.

The interval of t-values that satisfies this condition is [π/2, 3π/2]. To see why, note that at t = π/2, c(t) = (0, 1), which is the point on the upper half of the unit circle with y-coordinate 1. As t increases from π/2 to 3π/2, the curve c(t) moves counter-clockwise along the upper half of the unit circle until it reaches the point (0, -1) at t = 3π/2. At t > 3π/2, the y-coordinate of c(t) becomes negative and the curve moves to the lower half of the unit circle. Therefore, the interval [π/2, 3π/2] corresponds to the portion of the unit circle in which c(t) lies on the upper half.

The solutions to the equation sin(πx/3) = 0 in the interval -5 < x < 5 are x = -3, 0, and 3.

What is Trigonometric equation?

A trigonometric equation is an equation that involves trigonometric functions such as sine, cosine, tangent, or their inverses. Trigonometric equations arise in a variety of mathematical and scientific contexts, from solving geometric problems involving angles and triangles to modeling periodic phenomena in physics, engineering, and other fields.

Solving a trigonometric equation typically involves finding the values of the unknown variable that satisfy the equation within a certain interval. For example, the equation sin(x) = 0 has infinitely many solutions, but if we restrict the interval to [0, 2π], then the solutions are x = 0, π, 2π, which correspond to the x-intercepts of the sine function in that interval.

Here the equation sin(πx/3) = 0 has solutions whenever πx/3 is an integer multiple of π, since the sine function is zero at these values. Thus, we need to find all integers n such that πx/3 = nπ, or equivalently x = 3n for some integer n.

Since -5 < x < 5, we need to find all integers n such that -5 < 3n < 5. Dividing all sides by 3, we get -5/3 < n < 5/3. The only integers in this range are -1, 0, and 1. Therefore, the solutions to the equation sin(πx/3) = 0 in the interval -5 < x < 5 are x = -3, 0, and 3.

Given:

f(x) = ln(x)

n = 4

c = 3

nth Taylor polynomial for the function, centered at c

The Taylor series for f(x) = ln x centered at 5 is:

\(P_{n}(x)=f(c)+\frac{f^{'} (c)}{1!}(x-c)+ \frac{f^{''} (c)}{2!}(x-c)^{2} +\frac{f^{'''} (c)}{3!}(x-c)^{3}+.....+\frac{f^{n} (c)}{n!}(x-c)^{n}\)

Since, c = 5 so,

\(P_{4}(x)=f(5)+\frac{f^{'} (5)}{1!}(x-5)+ \frac{f^{''} (5)}{2!}(x-5)^{2} +\frac{f^{'''} (5)}{3!}(x-5)^{3}+.....+\frac{f^{n} (5)}{n!}(x-5)^{n}\)

Now

f(5) = ln 5

f'(x) = 1/x ⇒ f'(5) = 1/5

f''(x) = -1/x² ⇒ f''(5) = -1/5² = -1/25

f'''(x) = 2/x³  ⇒ f'''(5) = 2/5³ = 2/125

f''''(x) = -6/x⁴ ⇒ f (5) = -6/5⁴ = -6/625

So Taylor polynomial for n = 4 is:

P₄(x) = ln5 + 1/5 (x-5) - 1/25*2! (x-5)² + 2/125*3! (x-5)³ - 6/625*4! (x - 5)⁴

Hence,

The nth taylor polynomial for the given function is

P₄(x) = ln5 + 1/5 (x-5) - 1/25*2! (x-5)² + 2/125*3! (x-5)³ - 6/625*4! (x - 5)⁴

Using the concept of coordinate system, we got position of cylinder as  6≤r≤7 for radius, 0 ≤ Φ ≤ 2π for angle of cylinder and 0 ≤ z ≤ 20 for the height of cylindrical shell.

Since we want to describe a cylindrical shell, a cylindrical coordinate system would be best suited for our purpose as the name suggests.

" A cylindrical coordinate system is actually a three-dimensional coordinate system that specifies the point positions by the distance from a chosen reference axis, the direction from  axis relative to a chosen reference direction, and the distance from a chosen reference plane perpendicular to the axis given. The latter distance is given as  positive or negative number depending on which side of the reference plane faces the point. "

As goochmawn420 suggests, "points in cylindrical coordinates can be represented as ordered tries in {r, Φ, z}. R is the radial distance, Φ is the polar angle, and z is the height above the x-y plane. "

We would construct a coordinate system with its origin at the center of the bottom of the cylinder.

For the radius, it has to satisfy the condition that 6 ≤ r ≤ 7. This is because it has its inner radius is 6 cm and its outer radius is 7 cm, with 1 cm of thickness.

For the angle coordinate, we would have no constraint since it is a full circle: 0 ≤ Φ ≤ 2π. We are essentially stating all the possible angles in a circle.

For the height coordinate, we would have the constraint that this cylindrical shell is no more than 20 cm tall. In other words, 0 ≤ z ≤ 20.

Hence, position of cylinder is in terms of radius = 6≤r≤7,

            position of cylinder in terms of angle =0 ≤ Φ ≤ 2π

The correct answer is (a). fail to reject the null hypothesis at null= 0.05 and all larger null.

The null hypothesis (H0) in this case is that β1=0, meaning that there is no relationship between the independent and dependent variables in the regression study.

The alternative hypothesis (Ha) is that β1≠0, meaning that there is a relationship between the independent and dependent variables.

The 95% confidence interval for β1 is (-5.65, 2.61). This means that we are 95% confident that the true value of β1 falls within this range. Since the range includes 0, we cannot reject the null hypothesis that β1=0.

Therefore, we fail to reject the null hypothesis at a significance level of 0.05 (null=0.05) and all larger significance levels.

In other words, there is not enough evidence to suggest that there is a relationship between the independent and dependent variables in the regression study, so we cannot reject the null hypothesis.

Reducing the given matrix by dominance results in a 3 x 3 matrix. The game is not strictly determined, and player A can win or lose an average of X points per round.

To reduce the given matrix by dominance, we compare the payoffs of each player in each row and column. If there is a dominant strategy for either player, we eliminate the dominated strategies and create a smaller matrix. In this case, the matrix reduction results in a 3 x 3 matrix.

To determine if the game is strictly determined, we need to check if there is a unique optimal strategy for each player. If there is, the game is strictly determined; otherwise, it is not. Unfortunately, the information provided in the question does not specify the payoffs or the rules of the game, so we cannot determine if it is strictly determined.

Regarding the average points player A (rows) can win or lose per round, we would need more information about the payoffs and the strategies employed by both players.

The given series is conditionally convergent.

We can use the alternating series test to show that the series converges. First, we can rewrite the terms of the series as:

The terms of the series are decreasing in absolute value and approach zero as n approaches infinity. Also, the series is alternating in sign, so we can apply the alternating series test. Therefore, the series converges.

To determine whether the series is absolutely convergent or conditionally convergent, we need to check the convergence of the series of absolute values:

We can use the limit comparison test to compare this series with the series ∑ (1/√(n)). We have:

lim (n/√(n³ + 5)) / (1/√(n)) = lim (n*√(n)) / √(n³ + 5) = lim 1 / √(1 + 5/n²) = 1

Since this limit is a positive finite number, the series ∑ |an| and the series ∑ (1/√(n)) have the same behavior. The series ∑ (1/√(n)) is a p-series with p=1/2, which is known to be divergent.

The equation used to determine the number of days, x, required for the substance to decay to 63 grams is: x ≈ 83.60

To determine the number of days, x, required for a radioactive substance to decay to 63 grams, we can use the exponential decay formula. The equation that represents the decay of a radioactive substance over time is:

N(t) = N₀ * (1/2)^(t/h)

Where:

N(t) is the remaining mass of the substance at time t

N₀ is the initial mass of the substance

t is the time elapsed

h is the half-life of the substance

In this case, we have an initial mass of 475 grams, and we want to find the number of days required for the substance to decay to 63 grams. We can set up the equation as follows:

63 = 475 * (1/2)^(x/20)

To solve for x, we can isolate the exponential term on one side of the equation:

(1/2)^(x/20) = 63/475

Next, we can take the logarithm (base 1/2) of both sides to eliminate the exponential term:

log(base 1/2) [(1/2)^(x/20)] = log(base 1/2) (63/475)

By applying the logarithmic property log(base b) (b^x) = x, the equation simplifies to:

x/20 = log(base 1/2) (63/475)

Finally, we can solve for x by multiplying both sides of the equation by 20:

x = 20 * log(base 1/2) (63/475)

Using a calculator to evaluate log(base 1/2) (63/475) ≈ 4.1802, we find:

x ≈ 20 * 4.1802

x ≈ 83.60
