Answer and explanation:

A center chord in a circle is the diameter of that circle. Therefore a center chord of a circle is different from other chords that touch two points on the circle but not in the center of the circle. A diameter of a circle is the chord that runs the length of the center of the circle touching two points at the edge of the circle. A diameter is twice the radius of the circle. So if the diameter of the circle is 12cm then the radius of the circle is 6cm

The unknown angles of the rhombus are as follows:

A rhombus is a 2-D shape with four sides hence termed as a quadrilateral. The sides are equal and diagonals intersect each other at 90 degrees.

The properties of a rhombus are as follows:

Therefore,  the angles m∠ 2 and m∠3 can be calculated as follows:

m ∠ 1 = m ∠2 = 140 degrees

The triangles formed at the two halves of the rhombus are isosceles triangle.

Therefore,

2(∠3) = 180 - 140

2(∠3)  = 40

∠3 = 40 / 2

Therefore,

∠3 = 20 degrees

Step-by-step explanation:

Volume of a cylinder

\(\sf V=\pi r^2 h \quad\textsf{(where r is the radius and h is the height)}\)

Given:

Use the Volume of a Cylinder formula and the given values to find the radius of the cylinder:

\(\implies \sf 1715=\pi r^2 (18)\)

\(\implies \sf r^2=\dfrac{1715}{18 \pi}\)

\(\implies \sf r=\sqrt{\dfrac{1715}{18 \pi}\)

Surface Area of a Cylinder

\(\sf SA=2 \pi r^2 + 2 \pi r h \quad\textsf{(where r is the radius and h is the height)}\)

Substitute the given value of h and the found value of r into the formula and solve for SA:

\(\implies \sf SA=2 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)^2 + 2 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)(18)\)

\(\implies \sf SA=2 \pi \left(\dfrac{1715}{18 \pi} \right) + 36 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)\)

\(\implies \sf SA=\dfrac{1715}{9} + 36 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)\)

\(\implies \sf SA=813.3908956...\)

Therefore, the surface area of the cylinder is 813.4 cm² (nearest tenth)

Yes the graph of the function represents a linear piecewise function of x.

From the graph we can see that the function can be broken down into 3 distinct parts.

Let us take the first part of the graph which represents the function:

For values of x ranging from negative infinity to 0, the value of y is 2 .

So the function is of the form y = 2.

Now for the second slanting part of the function.

The function passes through the points (0,2) and (2,-2)

Slope of the line = (-2-2)/(2-0) = -2

Equation of the line :

y-2 = -2(x)

or, y + 2x = 2.

Now for the third part of the function is y = -2 for all x>2

Hence the piecewise function can be represented as for the domain of x:

     {2 , x < -2 }

y = {2-2x , -2 ≤ x ≤ 2}

     {-2 , x > 2}

Hence all parts are linear so the function is linear in nature.

The graph of the function y = \(x^{2}\) intersects the horizontal line y = 0 at the origin.

What is a function?

A function is a mathematical expression, rule, or law that explains how one independent variable and one dependent variable interact.

In the question, we are provided a function as y = \(x^{2}\) and the horizontal line is y = 0.

We know that the function y = \(x^{2}\) will pass through the origin and will always lie in the first and the second quadrant as y will always be positive.

Also, the given line will lie on the x - axis which means that it will pass through the origin.

So, the two will intersect at the origin.

A graph has been attached below which depicts the relationship between the two.

Hence, the graph of the function y = \(x^{2}\) intersects the horizontal line y = 0 at the origin.

Answer:

6/7

Step-by-step explanation:

Your first step will be to find the slope of Line C. Using the slope formula of \(\frac{y_{2}-y_1 }{x_2-x_1}\), the slope of Line C is \(\frac{7-14}{7-1} = \frac{-7}{6}\).

If Line D is perpendicular to C, that means the slope is the negative reciprocal of Line C. So, that means the slope is 6/7.

\(w {}^{ - 6} \)

Using the product of power rule,

\( {x}^{a } \times x {}^{e} = x {}^{a + e} \)

Precession is a phenomenon that refers to the gradual and continuous change in the orientation of the Earth's rotational axis over long periods of time.

This shift in the orientation of the axis of rotation results in changes in the position of the celestial pole with respect to the stars, which causes a shift in the apparent position of stars over time. The precession of the Earth's axis is caused by the gravitational forces of the Sun, Moon, and other planets in the solar system.
Precession is characterized by changes in the magnitude of the angle of tilt, which causes changes in the rate of the Earth's spin. As the axis of rotation moves, it causes the length of the day to change over time. Additionally, deviations in the circularity of the orbit also affect the precession of the Earth's axis.
Precession is a significant phenomenon in astronomy and has been observed for thousands of years. It has important implications for studies of astronomy, geology, and climate change. For instance, precession affects the timing of the seasons and has a significant impact on the Earth's climate. It also affects the orientation of the Earth's magnetic field, which has important implications for navigation and communication systems.
In conclusion, precession is the gradual change in the orientation of the Earth's rotational axis, caused by the gravitational forces of the Sun, Moon, and other planets. It results in changes in the magnitude of the angle of tilt, changes in the rate of Earth's spin, and deviations in the circularity of the orbit. Precession has significant implications for various fields of study, including astronomy, geology, and climate change.

Probability simply means the likelihood of the occurence of an event.

When there is a 3 percent chance or finding something special in a box,the number of boxes that will be opened will be illustrated thus:

Let the number of boxes be 100.

Answer:

There were 60 kids in class.

Step-by-step explanation:

Since the kids had two choices and the ratio between them was for every 3 children that selected "Shin Chan" only 1 selected "Tom and Jerry", then in order to calculate the number of children in the class if 45 kids selected "Shin Chan", we first need to calculate the number of children that selected the other option. To do that we divide the number by 3. We have:

children(Tom and Jerry) = children(Shin Chan)/3

children(Tom and Jerry) = 45/3 = 15

Therefore the number of children in the class is:

children(class) = children(Tom and Jerry) + children(Shin Chan)

children(class) = 15 + 45 = 60

There were 60 kids in class.

Answer:

She will ride 13 miles in one hour

Step-by-step explanation:

(8 2/3) / (2/3) = x / 1....8 2/3 miles to 2/3 hr = x miles to 1 hr

cross multiply

(2/3)(x) = (8 2/3)(1)

2/3x = 26/3

x = 26/3 * 3/2

x = 26/2...which equals 13....she will ride 13 miles in 1 hr

Answer:

Domain is All Real x.

Range is f(x) ≥ 2.

Step-by-step explanation:

The vertical lines about the x - 1 means the Absolute value ( always positive).

|x - 1| will always be positive or 0 and it's graph is  shaped like a V with the vertex at (1, 0)

The + 2 will move the graph up 2 units so the vertex becomes (1, 2).

The vector position of the projectile after 2 seconds is approximately 7.2 meters upwards from the initial position. After 10 seconds, the vector position is approximately 20.0 meters downwards from the initial position.

To find the vector position of the projectile at a given time, we can use the position function s(t) = -4.9t^2 + V0t + s0, where t represents time, V0 represents the initial velocity, and s0 represents the initial position. In this case, the initial velocity V0 is 3 meters per second, and the initial position s0 is 0 (since the projectile is shot from the surface of the Earth).

For t = 2 seconds, substituting the values into the position function gives s(2) = -4.9(2)^2 + 3(2) + 0 = 7.2 meters. This means that after 2 seconds, the projectile is 7.2 meters upwards from the initial position.

Similarly, for t = 10 seconds, substituting the values into the position function gives s(10) = -4.9(10)^2 + 3(10) + 0 = -196 + 30 = -166 meters. Since the result is negative, it indicates that after 10 seconds, the projectile is 166 meters downwards from the initial position. The vector position of the projectile after 2 seconds is approximately 7.2 meters upwards, and after 10 seconds, it is approximately 20.0 meters downwards from the initial position.
