A line is characterized by its length exceeding its width and the path it takes. Its qualities can express emotions and control the viewer's attention, with variations such as curved or angular, smooth or staccato, and different thicknesses. Lines play a crucial role in defining shapes and in expressive forms of writing such as calligraphy.
The characteristics of a line in design are defined by its length being greater than its width and by the paths it takes. A line is essentially a point in motion and is characterized by how it is used in art to determine motion, direction, and energy. When speaking of the qualities of a line, we refer to its character which can animate a surface. Lines can be curved or angular, and can progress smoothly or with a staccato rhythm, and they can be thick or thin, pale or bold.<\/p>
Lines have an emotional and expressive content that is understood both rationally and emotionally; they can control the viewer's attention and direction. Different types of lines like outline or contour line define shapes. Moreover, lines are integral to objects and writing symbols, where they denote meaning and can be expressive in themselves, illustrating their significance in calligraphy and other forms of art.<\/p>
Gestures are also related to lines, where a line produced by the artist's movement can be interpreted in various ways, like conveying calm with evenly drawn horizontal lines or rigidity with straight lines, which can be impactful depending on the context.<\/p>

If (x-4) is a factor of x^2-x-w=0, then the value of w is
Step-by-step explanation:
If x-4 is factor, then one value of x is 4
4²-4-w=0
12-w=0
w=12
➷ You have to find a value that, when added to -4, gives -1
This value is +3
The factored form would be (x - 4)(x + 3)
Expand this out:
x^2 + 3x - 4x - 12
==> x^2 -x -12 = 0
w = -12

What is the length of AB⎯⎯⎯⎯⎯ ? Enter your answer in the box. Round only your final answer to the nearest whole number. cm Triangle A B C has angle A labeled 80.4 degrees with its opposite side labeled 17 and angle C labeled 48.9 degrees with its opposite side labeled c.
Answer:
AB = 12.99
Step-by-step explanation:
To answer this problem, use the breast theorem.
[tex]\frac{sinA}{a} = \frac{sinC}{c}[/tex]
The side opposite angle C is denoted by the letter c. It is also denoted as AB side
We know that:
A = 80.4°
a = 17
C = 48.9
Then we have that:
[tex]\frac{sin(80.4\°)}{17} = \frac{sin(48.9\°)}{c}[/tex]
Now clear the variable c from the equation
[tex]c = \frac{sin(48.9\°)}{\frac{sin(80.4\°)}{17}}[/tex]
[tex]c = 12.99[/tex]

a teacher is holding tryouts for a school play. there are 15 students trying out for 7 parts in the play each student can play each part. in how many ways can the teacher select the students?
Answer:
6,435
Step-by-step explanation:
To find the number of ways the teacher can select the students, we can use the combination formula.
[tex]_{n}C_{k}=\dfrac{n!}{k!(n-k)!}[/tex]
n = 15
k = 7
Now let's plug it in.
[tex]_{n}C_{k}=\dfrac{n!}{k!(n-k)!}[/tex]
[tex]_{15}C_{7}=\dfrac{15!}{7!(15-7)!}[/tex]
[tex]_{15}C_{7}=\dfrac{15!}{7!8!}[/tex]
[tex]_{15}C_{7}=6,435[/tex]
So there are 6,435 ways that the teacher can select the students.

The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
here [ a, b ] = [ 0, 2 ] and from the graph
f(b) = f(2) = 0

The cross-section of a ramp is a triangle with side lengths of 9 inches, 40 inches, and 41 inches. Is this a right triangle?
Answer: True.
Step-by-step explanation: For this to be true, then:
[tex]9^2+40^2(=?)41^2[/tex]
[tex]81+1600 (=?) 1681[/tex]
[tex]1681=1681[/tex]
Yes, the ramp is indeed a right triangle.
Final answer:
The triangle with sides of 9 inches, 40 inches, and 41 inches is a right triangle, as it satisfies the Pythagorean theorem (9² + 40² = 41²).
Explanation:
A student asked if a ramp with a triangular cross-section and side lengths of 9 inches, 40 inches, and 41 inches is a right triangle. To determine this, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
For the triangle in question, if we square each of the side lengths and add the squares of the shorter sides, we should get the square of the longest side if it is indeed a right triangle:
9² = 8140² = 160041² = 1681Then add the squares of the two shorter sides:
81 + 1600 = 1681
Since 1681 equals 41², the triangle with sides of 9 inches, 40 inches, and 41 inches satisfies the Pythagorean theorem, confirming it is a right triangle.

Point A(-7, -2) is rotated 270° counterclockwise and then shifted down 3 units. What are to coordinates of K’?
A. (2,4)
B. (-2, -7)
C. (-2, 4)
D. (7, -5)
Answer:
C. (-2, 4)
Step-by-step explanation:
First we are going to rotate the point 270°; then we are going to shift it down 3 units.
Remember that the rule to rotate a point 270° counterclockwise about the origin is:
[tex]R_{270}(y,-x)[/tex]
In other words, we just need to switch the coordinates and change the sign of the second coordinate. Let's apply the rule to our point:
[tex]A = (-7, -2)[/tex]
[tex]A'=(y,-x)=(-2,--7)=(-2,7)[/tex]
Now we know that the coordinates of our point after the rotation are A' = (-2, 7)
The only thing left is shift that point 3 units down; to do it, we just need to subtract 3 from the y-coordinate:
[tex](x,y)-->(x,y-3)[/tex]
[tex]A'=(-2,7)[/tex]
[tex]K'=(-2,7-3)[/tex]
[tex]K'=(-2,4)[/tex]
We can conclude that after a rotation of 270° and a translation 3 units down, the coordinates of point K' are (-2, 4).

Answer:
2/3
Step-by-step explanation:
Given in the question two points
(84,80) and (74,65)
Here
x1 = 84
x2 = 74
y1 = 80
y2 = 65
Slope of line means gradient of line and formula to calculate gradient of line is
gradient = [tex]\frac{x2-x1}{y2-y1}[/tex]
plug values in the formula
[tex]\frac{74-84}{65-80}[/tex]
[tex]\frac{-10}{-15}[/tex]
cancel - sign

Tell if the slope is positive, negative , zero , or no slope
Answer:
No slope
Step-by-step explanation:
The slope of a line or segment in the Cartesian plane is zero if from left to right the value on the y-axis increases, and negative if from left to right the value on the y-axis decreases. So in this case the line is neither positive nor negative.
A slope is zero if the line is horizontal, and because the line in the figure is vertical, its slope is not zero.
For vertical lines in the plane it is said that they have no slope or that it is undefined.
Find the area and perimeter of the following figure
Answer:
143.79
Step-by-step explanation:
The area of the figure can be found by splitting it into two shapes - a semi circle and a trapezoid.
The area of a semi-circle is found using A = 1/2πr² where r = 4.5 since the diameter is 9. A = 1/2π(4.5)² = 31.79.
The area of the trapezoid is found using A = 1/2(a+b)h = 1/2(23 + 9)(7) = 112.
Together the area is 31.79 + 112 = 143.79.

what is the diameter of the following circle? (x-6)^2 + (y-7)^2 =25
Answer:
d = 10Step-by-step explanation:
The standard form of an equation of a circle:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
(h, k) - center
r - radius
We have the equation:

h = 6, k = 7, r = √25 = 5
The diameter d = 2r → d = 2(5) = 10
Factor 1/7 out of 1/7x+46/7. 1/7x+46/7=
Final answer:
To factor 1/7 out of 1/7x+46/7, you can factor it out of each term separately and then combine like terms.
Explanation:
To factor 1/7 out of 1/7x+46/7, you can factor it out of each term separately. So you would have:
1/7(1/7x) + 1/7(46/7)
Simplifying each term gives us:
1/49x + 1/49(46)
Finally, you can combine like terms to get the answer:

whats the sum of f and g ?

a) (f+g)(x)=5+5x
b) (f+g)(x)=5+9x
c) (f+g)(x)=15+5x
d) (f+g)(x)=15+9x
Answer:
C
Step-by-step explanation:
Basically (f+g)(x) = f(x)+g(x).
Following this rule you combine like terms.
7x-2x=5x and 10+5 = 15.
Therefore the answer is C.
f(x) = 10 - 2x
g(x) = 7x + 5
(f + g) (x) = (10 - 2x) + (7x + 5) //Adding two functions
= 10 - 2x + 7x + 5
= 15 + 5x
