Answer:

632.83mm²

Step-by-step explanation:

Applying Pythagorean theorem to triangle SOH

SH² = SO² + OH²

SH = \(\sqrt{(15.4)^2+(7.2)^2}=17mm\)

Since the base of the pyramid is a regular pentagon, angle OAH
is 108°/2 = 54°.

AH = 7.2/tan 54° = 5.23mm

So AB = 2AH = 10.46mm

The area of triangle SAB is:

A1 = 1/2 × SH × AB = 1/2 × 17 × 10.46 = 88.91mm²

The area of all triangles is

A2 = 5 × A1 = 5 × 88.91 = 444.55mm²

The area of the base is:

A3 = (perimeter × apothem)/2 = (5 × 10.46 × 7.2)/2 = 188.28mm²

The surface area of the pyramid is:

A2 + A3 = 444.55 + 188.28 = 632.83mm²

Step-by-step explanation:

the surface area is the sum of the base area (pentagon) and the 5 side triangles (we only need to calculate one and then multiply by 5, as they are all equal).

these side triangles are isoceles triangles (the legs are equally long).

the usual area formula for a pentagon is

1/2 × perimeter × apothem

the apothem is the minimum distance from the center of the pentagon to each of its sides.

in our case this is 7.2 mm.

how to get the perimeter or the length of an individual side of the pentagon ?

if the apothem of a pentagon is given, the side length can be calculated with the formula

side length = 2 × apothem length × tan(180/n)

where 'n' is the number of sides (5 in our case). After getting the side length, the perimeter of the pentagon can be calculated with the formula

perimeter = 5 × side length.

so, in our case

side length = 2 × 7.2 × tan(180/5) = 14.4 × tan(36) =

= 10.4622124... mm

perimeter = 5 × 10.4622124... = 52.31106202... mm

area of the pentagon = 1/2 × perimeter × apothem =

= 1/2 × 52.31106202... × 7.2 = 188.3198233... mm²

now for the side triangles.

the area of such a triangle is

1/2 × baseline × height

baseline = pentagon side length

height we get via Pythagoras from the inner pyramid height and the apothem :

height² = 7.2² + 15.4² = 51.84 + 273.16 = 289

height = 17 mm

area of one side triangle =

1/2 × 10.4622124... × 17 = 88.92880543... mm²

all 5 side triangles are then

444.6440271... mm²

and the total surface area is then

444.6440271... + 188.3198233... = 632.9638504... mm²

≈ 632.96 mm²

The coordinates at which the tangent line to f(x) = (x-6/x)^8 is horizontal are (√6, f(√6)) and (-√6, f(-√6)), where f(x) is the given function.

To find the coordinates at which the tangent line to the function f(x) = (x-6/x)^8 is horizontal, we need to find the critical points of the function where the derivative is zero or undefined.

First, let's find the derivative of the function:

f(x) = (x-6/x)^8

f'(x) = 8(x-6/x)^7 * (1 - (-6/x^2))

Simplifying the second term, we get:

f'(x) = 8(x-6/x)^7 * (x^2+6)/x^2

Now we need to set the derivative equal to zero and solve for x:

8(x-6/x)^7 * (x^2+6)/x^2 = 0

(x^2+6) cannot be zero, so we can ignore that factor.

8(x-6/x)^7 = 0

(x-6/x) = 0

x^2 - 6 = 0

x = ±√6

So we have two critical points at x = √6 and x = -√6.

Now we need to determine whether these critical points correspond to a maximum, minimum, or inflection point. To do this, we can use the second derivative test.

Taking the derivative of the first derivative, we get:

f''(x) = 8(x-6/x)^6 * (56/x^3 + 7)

Evaluating the second derivative at x = √6, we get:

f''(√6) = 8(√6-6/√6)^6 * (56/√6^3 + 7)

f''(√6) > 0, so the function has a local minimum at x = √6.

Evaluating the second derivative at x = -√6, we get:

f''(-√6) = 8(-√6-6/-√6)^6 * (56/-√6^3 + 7)

f''(-√6) < 0, so the function has a local maximum at x = -√6.

Therefore, the coordinates at which the tangent line to f(x) = (x-6/x)^8 is horizontal are (√6, f(√6)) and (-√6, f(-√6)), where f(x) is the given function.

The snow that will be gotten daily of the line plot is redistributed equally will be 1/2.

A line plot, also known as a line graph, is a type of graph that displays information as a series of data points connected by straight lines. Line plots are often used to show how a particular variable changes over time or to compare two or more variables.

To create a line plot, you typically need to have a set of data points that represent the variable you want to graph. You then plot each data point on a graph, with the x-axis representing time or some other variable, and the y-axis representing the value of the variable you're graphing.

The snow that will be gotten daily of the line plot is redistributed equally will be:

Step-by-step explanation:

The general form of a quadratic function is given by:f(x) = ax^2 + bx + cwhere a, b, and c are constants.To find the specific equation of a quadratic function with a given vertex and a point on the graph, we can use the vertex form of the quadratic function:f(x) = a(x - h)^2 + kwhere (h, k) is the vertex.Using the given vertex (0, 3), we have:f(x) = a(x - 0)^2 + 3Simplifying, we get:f(x) = ax^2 + 3Now we can use the given point (2, 7) to find the value of a.Substituting x = 2 and y = 7 into the equation above, we get:7 = a(2)^2 + 3Simplifying, we get:7 = 4a + 34a = 4a = 1Therefore, the general form of the quadratic function is:f(x) = x^2 + 3

Answer:

? = 9.2

Step-by-step explanation:

The angle between a tangent and radius at the point of contact is 90°

Then the triangle shown is right with legs ? , 6.9 and hypotenuse = (6.9 + 4.2) = 11.5

Using Pythagoras' identity in the right triangle

?² + 6.9² = 11.5²

?² + 47.61 = 132.25 ( subtract 47.61 from both sides )

?² = 84.64 ( take the square root of both sides )

? = \(\sqrt{84.64}\) = 9.2

Answer:

Solution given:

BC=BD=6.9 units

AD=4.6units

Now

AB=4.6+6.9=11.5units.

we have

<C=90°[the line from the tangent is perpendicular to the radius of circle]

we know that ∆ABC is a right angled triangle.

hypotenuse [h]=AB=11.5units

base[b]=BC=6.9 units

perpendicular [p]=x units

By using Pythagoras law

h²=p² +b²

11.5²=x²+6.9²

x²=11.5²-6.9²

x²=84.64

x=\( \sqrt{86.64} \)=9.2

Answer: 172 ounces

Step-by-step explanation:

We are given 10 pounds and 12 ounces to convert to ounces.

There are 16 ounces in 1 pound.

We can create a proportion to find out how much ounces 10 pounds is.

10 pounds / x ounces = 1 pound / 16 ounces

We need to solve for x by isolating the variable x.

10/x = 1/16

10 = x/16

10 * 16 = x

160 ounces = x

so 10 pounds is equivalent to 160 ounces. But we are not done yet.

We were asked to convert 10 pounds and 12 ounces.

So add together the ounces to find the total ounces:

160 ounces + 12 ounces = 172 ounces.

Answer: It is not possible for me to draw a slope triangle or dilate it along the graph without more information about Sara's monthly savings.

To determine whether the amount Sara saves each month is constant, you can choose any two points on the graph and use them to calculate the slope of the line connecting them. If the slope is constant for all pairs of points, then the amount Sara saves each month is constant. If the slope is not constant, then the amount Sara saves each month is not constant.

To calculate the slope of the line connecting two points, you can use the following formula:

slope = (y2 - y1)/(x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

You can then use the slope triangle to visualize the slope of the line connecting the two points. If you dilate the slope triangle along the graph and the slope remains constant, then the amount Sara saves each month is also constant.

A rotation 90° clockwise about the origin is the transformation that would accomplish the transformation from Figure U to Figure V.

Rotation is a type of motion where an object turns around its own axis. This motion is usually done in a circular or ellipse path and is used in many everyday activities such as spinning a top, riding a merry-go-round, or throwing a frisbee. It is also used in physics to describe the orbits of planets and other celestial bodies. Rotation is an important concept in physics, as it helps scientists explain the behavior of objects in the universe, such as the behavior of planets in orbit around the sun. Rotation also helps to explain the movement of air around the Earth, which affects weather patterns.

A rotation about the origin is a transformation where the figure is rotated around a fixed point, in this case the origin. Since Figure V is a 90° clockwise rotation of Figure U, this transformation is the one that would accomplish the transformation.

When a figure is rotated about the origin, the coordinates of each point in the figure are changed in relation to the origin. The distance from each point to the origin stays the same, but the angle the point makes with the origin is changed. In a clockwise rotation, the angle of the point increases by 90°, while in a counter clockwise rotation, the angle of the point decreases by 90°. In this case, rotating Figure U 90° clockwise about the origin will result in Figure V.
