Always true.
Horizontal line (mathmatic word definition) a line that goes from left to right along the x-axis of the coordinate plane

Always true because if u actually draw the chart u can see that the horizontal line is parallel to the x axis line

The axis of a great circle of a sphere is 24 inches. If its radius is 9 inches, how far is the plane of a section from the cente
Blababa [14]
A great circle is a section of a sphere that passes through its center. If the earth were a sphere, a great circle would be the equator and its axis would be the line connecting the geographic north and south pole. The length of the axis is then equal to the diameter of the sphere. For this problem, the radius of the sphere is 12 inches. A section is formed by slicing through the sphere and all sections of a sphere are circles. Considering the plane to be cut above and parallel with the equator (which is a great circle), the distance of the plane from the center of the sphere would then be the distance between the centers of the sphere and section. It is also given that the radius of the section is 9 inches. A right triangle is formed by connecting the center of the sphere, an edge of the section, and back to the center of the sphere whose hypotenuse is 12 inches (radius of the sphere), one leg is the 9 inches (radius of the section), and another leg is the distance of the plane from the sphere's center. Thus, the distance can be calculated using the Pythagorean theorem, d = sqrt(12^2 - 9^2) = sqrt(144 - 81) = sqrt(63) = 3*sqrt(7).

In a scale drawing, a building has a length of 15 cm. The actual length of the building is 37.5 feet. Whats the scale of the dra
Feliz [49]

Answer:

\frac{15}{37.5}\ \frac{cm}{ft}

or

1.31:100

Step-by-step explanation:

we know that

The scale of the drawing is equal to divide the length of a building in the scale drawing by the actual length of a building

so

\frac{15}{37.5}\ \frac{cm}{ft}

That means

15 cm in the drawing represent 37.5 ft in the actual

Remember that

1\ ft=30.48\ cm

Convert 15 cm to ft

divide by 30.48

15\ cm=15/30.48\ ft

substitute

\frac{15}{37.5}\ \frac{cm}{ft}=\frac{(15/30.48)}{37.5}=\frac{0.0131}{1}

or

1.31:100

That means

1.31 units in the drawing represent 100 units in the actual

The equation of a circle is given below.
BARSIC [14]

<u>Given</u>:

The equation of the circle is x^2+(y+4)^2=64

We need to determine the center and radius of the circle.

<u>Center</u>:

The general form of the equation of the circle is (x-h)^2+(y-k)^2=r^2

where (h,k) is the center of the circle and r is the radius.

Let us compare the general form of the equation of the circle with the given equation x^2+(y+4)^2=64 to determine the center.

The given equation can be written as,

(x-0)^2+(y+4)^2=64

Comparing the two equations, we get;

(h,k) = (0,-4)

Therefore, the center of the circle is (0,-4)

<u>Radius:</u>

Let us compare the general form of the equation of the circle with the given equation x^2+(y+4)^2=64 to determine the radius.

Hence, the given equation can be written as,

x^2+(y+4)^2=8^2

Comparing the two equation, we get;

r^2=8^2

 r=8

Thus, the radius of the circle is 8
