Answer:

112 degrees

Step-by-step explanation:

The other 2 interior angles are (180-44)/2 which is 68.

180 (straight line) -68 = 112

15 posts plus 2 corner posts = 17 posts. With 17 posts there would be 16 spaces each side.

The space between each is 8 1/8 feet.

The length of one side is the number of spaces multiplied by the distance between each space.

Total length of one side = 16 spaces x 8 1/8 feet = 130 feet

Area = length x width.

It’s a square shape so area = 130 x 130 = 16,900 square feet

Perimeter is the distance around the square, this would be the length of one side x the number of sides.

Perimeter = 130 x 4 = 520 feet

Answer:

Step-by-step explanation:

a)  The x-intercepts of the graph of f(x) are x = 2.5 and x = -1.

b) The coordinates of the vertex are (0.75, -5.125).

c) By using the x-intercepts and vertex obtained in Parts A and B, we can accurately depict the shape and positioning of the parabolic graph of f(x).

Part A: To find the x-intercepts of the graph of f(x), we set f(x) equal to zero and solve for x.

Setting f(x) = 0:

\(2x^2 - 3x - 5 = 0\)

To solve this quadratic equation, we can either factor it or use the quadratic formula. In this case, factoring is not straightforward, so let's use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

For our equation, a = 2, b = -3, and c = -5. Substituting these values into the quadratic formula:

x = (-(-3) ± √((-3)^2 - 4(2)(-5))) / (2(2))

x = (3 ± √(9 + 40)) / 4

x = (3 ± √49) / 4

x = (3 ± 7) / 4

This gives us two possible solutions:

x1 = (3 + 7) / 4 = 10/4 = 2.5

x2 = (3 - 7) / 4 = -4/4 = -1

Therefore, the x-intercepts of the graph of f(x) are x = 2.5 and x = -1.

Part B: To determine whether the vertex of the graph of f(x) is a maximum or minimum, we need to consider the coefficient of the x^2 term in the function f(x). In this case, the coefficient is positive (2), which means the parabola opens upward and the vertex represents a minimum point.

To find the coordinates of the vertex, we can use the formula x = -b / (2a). In our equation, a = 2 and b = -3:

x = -(-3) / (2(2))

x = 3 / 4

x = 0.75

To find the corresponding y-coordinate, we substitute x = 0.75 into the function f(x):

f(0.75) = 2(0.75)^2 - 3(0.75) - 5

f(0.75) = 2(0.5625) - 2.25 - 5

f(0.75) = 1.125 - 2.25 - 5

f(0.75) = -5.125

Therefore, the coordinates of the vertex are (0.75, -5.125).

Part C: To graph the function f(x), we can follow these steps:

Plot the x-intercepts obtained in Part A: (2.5, 0) and (-1, 0).

Plot the vertex obtained in Part B: (0.75, -5.125).

Determine if the parabola opens upward (as determined in Part B) and draw a smooth curve passing through the points.

Extend the curve to the left and right of the vertex, ensuring symmetry.

Label the axes and any other relevant points or features.

By using the x-intercepts and vertex obtained in Parts A and B, we can accurately depict the shape and positioning of the parabolic graph of f(x).

The x-intercepts help determine where the graph intersects the x-axis, and the vertex helps establish the lowest point (minimum) of the parabola. The resulting graph should show a U-shaped curve opening upward with the vertex at (0.75, -5.125) and the x-intercepts at (2.5, 0) and (-1, 0).

The first five nonzero terms of the Taylor series for\(f(x) = \frac{7 \cdot \arctan(x)}{\frac{\pi}{24}}\) about the point a = 1 are \(7 + \frac{84}{\pi}(x - 1) - \frac{84}{\pi}(x - 1)^2 + 0 + 0\)

The first five nonzero terms of the Taylor series generated by the function \(f(x) = \frac{7 \cdot \arctan(x)}{\frac{\pi}{24}}\) about the point a = 1 can be found using the definition of the Taylor series.

The general form of the Taylor series expansion is given by:

\(f(x) = f(a) + f'(a)(x - a) + (f''(a)(x - a)^2)/2! + (f'''(a)(x - a)^3)/3! + (f''''(a)(x - a)^4)/4! + ...\)

To find the first five nonzero terms, we need to evaluate the function f(x) and its derivatives up to the fourth derivative at the point a = 1.

First, let's find the function and its derivatives:

\(f(x) = \frac{7 \cdot \arctan(x)}{\frac{\pi}{24}}\)

\(f'(x) = \frac{7}{\frac{\pi}{24} \cdot (1 + x^2)}\)

\(f''(x) = \frac{-7 \cdot (2x)}{\frac{\pi}{24} \cdot (1 + x^2)^2}\)

\(f'''(x) = \frac{-7 \cdot (2 \cdot (1 + x^2) - 4x^2)}{\frac{\pi}{24} \cdot (1 + x^2)^3}\)

\(f''''(x) = \frac{-7 \cdot (8x - 12x^3)}{\frac{\pi}{24} \cdot (1 + x^2)^4}\)

Now, let's substitute the value of a = 1 into these expressions and simplify:

\(f(1) = \frac{7 \cdot \arctan(1)}{\frac{\pi}{24}} = 7\)

\(f'(1) = \frac{7}{\frac{\pi}{24} \cdot (1 + 1^2)} = \frac{84}{\pi}\)

\(f''(1) = \frac{-7 \cdot (2 \cdot 1)}{\frac{\pi}{24} \cdot (1 + 1^2)^2} = \frac{-84}{\pi}\)

\(f'''(1) = \frac{-7 \cdot (2 \cdot (1 + 1^2) - 4 \cdot 1^2)}{\frac{\pi}{24} \cdot (1 + 1^2)^3} = 0\)

\(f''''(1) = \frac{-7 \cdot (8 \cdot 1 - 12 \cdot 1^3)}{\frac{\pi}{24} \cdot (1 + 1^2)^4} = 0\)

Now we can write the first five nonzero terms of the Taylor series:

\(f(x) = 7 + \frac{84}{\pi}(x - 1) - \frac{84}{\pi}(x - 1)^2 + \dots\)

These terms provide an approximation of the function f(x) near the point a = 1, with increasing accuracy as more terms are added to the series.

Step-by-step explanation:

The answer is (001). This is because B (001) has h and k as non-zero integers, which does not match the criteria for the {100} family.

The question is asking which of the planes (A), (B), (C), and (D) is not part of the {100} family for a tetragonal crystal.A tetragonal crystal is a three-dimensional structure made up of four faces that intersect at right angles, forming a unit cell. Each face of the unit cell is defined by a Miller index. A Miller index is a set of three integers written in the form {hkl}, which describes the orientation of the face relative to the crystal lattice. In a tetragonal crystal, the {100} family is the set of faces described by {hkl} such that h = k = 0 and l ≠ 0.

Therefore, A (010), C (110), and E (all of these planes are in the {100} family) are all part of the {100} family for a tetragonal crystal, while B (001) is not.  because B (001) has h and k as non-zero integers, which does not match the criteria for the {100} family.

the line through the shape line means that they are equivalent meaning the side that is empty not making the trapezoid would be 9 as well. moving the 3 over since it is right next to it. 3 times 9 equal 27cm^2. later we are gonna use this number to subtract

then make a different equation with 3+9 to the the full height of the trapezoid pretending it is not missing anything. 3+9=12

then use the formula to find the area of the trapezoid which is 1/2(h)(b1+b2)

add the 2 bases together to get 35. how did i get 35. 12+14=26 yes then include the 9 to get 35.

To estimate the number of new users that would be added during time period 7, we can use the Bass diffusion model, which is commonly used to model the adoption of new products or technologies.

The Bass diffusion model is given by the formula:

\(\[N(t) = \frac{{p \cdot q}}{{q + (p/q) \cdot e^{-((p+q) \cdot t)}}}\]\)

where:

- N(t) represents the cumulative number of adopters at time \(t\).

- p is the innovation parameter, representing the coefficient of innovation.

- q is the imitation parameter, representing the coefficient of imitation.

- e is the base of the natural logarithm.

Given a population size of 67 million, an innovation parameter of 0.005, and an imitation parameter of 0.84 for Color TV, we can substitute these values into the Bass diffusion model and calculate the number of new users added during time period 7.

\(\[N(7) - N(6) = \frac{{p \cdot q}}{{q + (p/q) \cdot e^{-((p+q) \cdot 7)}}} - \frac{{p \cdot q}}{{q + (p/q) \cdot e^{-((p+q) \cdot 6)}}}\]\)

Substituting the given values into the equation:

\(\[N(7) - N(6) = \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 7)}}} - \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 6)}}}\]\)

Evaluating the expression will give us the estimated number of new users added during time period 7.

In LaTeX, the solution can be represented as:

\(\[N(7) - N(6) = \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 7)}}} - \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 6)}}}\]\)

The value of \($\tan A$\) in its simplest radical form is \(8/3$.\)

What is radical form?

Radical form refers to a mathematical expression that includes radicals, which are symbols that indicate a root of a number.

To find the value of \($\tan A$\), we first need to determine the value of \(\cos A$.\)

Using the Pythagorean identity, we have:

\($$\sin^2 A + \cos^2 A = 1$$\)

Substituting the given value of \($\sin A$\), we get:

\($$\left(\frac{8}{\sqrt{73}}\right)^2 + \cos^2 A = 1$$\)

Simplifying the left-hand side, we get:

\($\frac{64}{73} + \cos^2 A = 1$$$$\cos^2 A = \frac{9}{73}$$$$\cos A = \frac{3}{\sqrt{73}}$$\)

Since angle \($A$\) is in the first quadrant, both \($\sin A$\) and \($\cos A$\) are positive.

Therefore, we have:

\($$\tan A = \frac{\sin A}{\cos A} = \frac{8/\sqrt{73}}{3/\sqrt{73}} = \frac{8}{3}$$\)

So the value of \($\tan A$\) in its simplest form is \(8/3$.\)

If the  box has the least possible surface area, then the dimension of box is a square base of 2 meters by 2 meters, and a height of 4 meters.

Let's call the side length of the square bottom "x" and the height of the box "h". Since the box has an open top, we don't need to worry about the surface area of the top. Therefore, we only need to consider the surface area of the bottom and sides.

The volume of the box is given as 32 cubic meters, so we can set up an equation:

Volume = x²h = 32

We want to minimize the surface area, which consists of the area of the bottom and the four sides. The area of the bottom is x², and the area of each side is xh. So, the total surface area is:

Surface Area = x² + 4xh

We can use the equation for the volume to solve for h in terms of x:

h = 32/x²

Substituting this expression for h into the equation for surface area gives:

Surface Area = x² + 4x(32/x²) = x² + 128/x

To minimize the surface area, we can take the derivative of this expression with respect to x and set it equal to zero:

d(Surface Area)/dx = 2x - 128/x² = 0

Solving for x, we get:

2x = 128/x²

x⁵ = 64

x = 2 meters

Substituting this value of x back into the equation for h gives:

h = 32/x² = 4 meters

Therefore, the dimensions of the box with the least possible surface area are:

Length = Width = x = 2 meters

Height = h = 4 meters
