How do you compare two slopes on a graph?
Two slopes can be compared on a graph by analyzing the steepness of the lines and their direction (positive or negative).
The steepness of a line on a graph is determined by its slope, which is the ratio of the change in y to the change in x (rise over run). A steep line has a large slope, meaning that for a small change in x, there is a large change in y. A shallow line has a small slope, meaning that for a small change in x, there is a small change in y. To compare two slopes, one can compare the steepness of the lines by comparing the absolute value of the slopes.
If one line has a larger absolute value than the other, it is steeper. Additionally, one can also compare the direction of the slope, which is determined by the sign of the slope. A positive slope indicates that the line is increasing and a negative slope indicates that the line is decreasing. By comparing the steepness and direction of the slopes, one can determine whether the two lines are parallel or not, and whether they are going in the same direction or not.

Answer:
31.4cm
Step-by-step explanation:
Formula for circumference of a circle:
[tex]C = 2\pi r[/tex]
The radius of a circle is half of the diameter:
10/2 = 5
Plug in the values using 3.14 for pi:
C = 2(3.14)(5)
C = 31.4cm
Answer:
D. 70.39
Step-by-step explanation:
This is not a good question, but I will show you how to get the answer I chose.
Area = (pi)(r)^2
394.38 = (3.14)(r)^2
divide both sides by 3.14
125.598726 = r^2
take the square root of both sides
r = 11.207083...
rounded is 11.21
---------------------------
Circumference = (2)(pi)(r)
C = (2)(3.14)(11.207083)
C = 70.38
----------------------------------------
Here's why it's a bad question:
If the diameter is 10, the radius is half of that, = 5
Area = (pi)(r)^2
Area = (3.14)(5)^2
A = (3.14)(25)
A = 78.5
So the question says the diameter is 10, but if that's true, the area cannot be 394.38
Also, the circumference can be calculated as (pi)(diameter), so 3.14 x 10 = 31.40, which is not an answer option.

How do you write an x-intercept as a point?
The X-intercept is the point where the line crosses the x-axis. This happens where the Y is equals to zero.
The point slope form of a line is an equation of the line that takes on the form y - y1 = m(x - x1). In this equation, m is the slope of the line, and (x1, y1) is a point on the line. The x-intercept of a line is the x-coordinate of the point where the line crosses the x-axis. This always happens at the point where y is equal to 0. Therefore, we find the x-intercept of a line in point-slope form by plugging y = 0 into the equation and then solving for x. The point-slope formula is composed of a specific point of coordinates and a slope indicating a type of change over a given variable, such as distance over time. It is said to be as the x-coordinate of a point where a line, curve, or surface intersects the x-axis.

I) if y varies directly as x and inversely as the square root of z, and y = 1/6 when x = 20 and z = 6, determine y when x = 14 and z = 5
Answer: Since y varies directly as x and inversely as the square root of z, we can write the following equation:
y = kx/(sqrt(z)), where k is a constant.
We can find the value of k by substituting the known values into the equation. We get:
1/6 = k*20/sqrt(6)
k = 1/240
Substituting this value of k into the original equation, we get:
y = (1/240)x/(sqrt(z))
Substituting the values x = 14 and z = 5 into this equation, we get:
y = (1/240)(14)/(sqrt(5)) = 7/120 sqrt(5) ≈ 0.22

How do you find the unknown part of a right triangle?
To find the unknown part of a right triangle, you can use the Pythagorean theorem or the trigonometric ratios.
A right triangle is a triangle that has one angle measuring exactly 90 degrees, this angle is called the right angle.
To find the unknown part of a right triangle, you can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (legs) is equal to the square of the length of the longest side (the hypotenuse). The formula is:
a² + b² = c²
Where c is the length of the hypotenuse and a and b are the lengths of the legs.
You can use this theorem to find the length of a missing side, if you know the length of the other two sides. For example, if you know the lengths of the two legs (a and b) and you need to find the length of the hypotenuse (c), you can use the formula:
c = √(a² + b²)
Alternatively, if you know the length of the hypotenuse (c) and one leg (a), you can use the formula to find the length of the other leg (b):
b = √(c² - a²)
Another way to find the unknown part of a right triangle is the use of trigonometric ratios. As you know, in a right triangle, there are three main ratios: sine, cosine, and tangent. These ratios are defined as follows:
Sin(A) = a/c
Cos(A) = b/c
Tan(A) = a/b
Where A is one of the acute angles of the triangle, and a,b,c are the sides of the triangle. By using the known side and the known angle you could find the unknown side.

Draw a line from E to the center of the circle. Label the center of the circle OOE and OF are both radii. They form the central angle of the ArcEFSolution
Find the value of Arc EF
The value of Arc EF = 360 - 244 = 116
The value of <FOE also = 116. (The arc and the central angle are equal.)
ΔFOE = 116 degrees See above statement
ΔFOE is isosceles Two of it's sides are radii.
The two base angles can be solved. Call each one x
2x + 116 = 180 All triangles have 180 degrees
-116 -116 Subtract 116 from both sides
2x = 64 Divide by 2
x = 32 <EFO = 32
<EFO = 90 Where the tangent meets the radius forms a 90o angle.
<EFO + GFE = 90
32 + GFE =90
GFE = 90 - 32

B.180°
C.216°
D.144°
Answer:
Step-by-step explanation:
It’s A
The measure of the arc ADC is 252°
What is an arc?The arc of a circle is defined as the part or segment of the circumference of a circle.
Given that, a circle O, with tangents AB and BC, the measure of arc AC is 108°, the measure of angle ABC is 72°, we need to find the measure of arc ADC,
According to the definition of circle,
We have,
m ∠ABC = (m arc ADC + m arc ADC) / 2
72° = (m arc ADC - 108°) / 2
144° = m arc ADC - 108°
m arc ADC = 144° + 108°
m arc ADC = 252°
Hence the measure of the arc ADC is 252°
