Does a parallelogram have four parallel sides?
NO!!!
The opposite sides are Parallel.
If it was four parallel sides it would be four parallel lines, with no intersections nor angles.
Definitely a parallelogram is a quadrilateral. It has its opposite sides to be parallel, and there are no right-angles.
The adjacent sides are NOT parallel, but angled.
What is the function of unpicker?
An unpicker, also known as a seam ripper, is a sewing tool designed to remove stitches. It typically features a pointed end that can easily slide under stitches and a small blade to cut them. It is especially useful for correcting mistakes or altering garments without damaging the fabric. This tool is essential for any sewing project where adjustments or repairs are needed.
What is the ordinate of a point lies on x -axis?
The ordinate of a point refers to its y-coordinate in a Cartesian coordinate system. For any point that lies on the x-axis, the y-coordinate is always zero. Therefore, the ordinate of a point on the x-axis is 0.
What statement best describe the transverse asix of a hyperbola?
The transverse axis of a hyperbola is the line segment that connects the two vertices of the hyperbola and lies along the central axis between them. It is oriented horizontally for a hyperbola that opens left and right, and vertically for one that opens up and down. The length of the transverse axis is equal to twice the distance from the center of the hyperbola to each vertex. This axis is crucial for defining the shape and orientation of the hyperbola.
Which direction would the graph of y equals -x plus 9 open?
Since 'x' and 'y' both appear to the first power, this is a linear equation.
That means that the graph is a straight line, and it doesn't 'open'.
The line has a slope of -1, and it cuts the y-axis at y=9.
Which way does a parabola open when the coefficent of its x2-term a is negative?
It opens DOWNWARD , like an 'umbrella'.
How do you solve 1.75 equals 0.2 g?
To solve the equation (1.75 = 0.2g), you need to isolate (g). This can be done by dividing both sides of the equation by (0.2):
[ g = \frac{1.75}{0.2} ]
Calculating that gives (g = 8.75). Thus, the solution is (g = 8.75).
What is the meaning of complement in Boolean Algebra?
In Boolean algebra, the complement of a variable is the opposite value of that variable. For a given variable ( A ), its complement is denoted as ( A' ) or ( \overline{A} ), and it takes the value 1 when ( A ) is 0, and vice versa. The complement operation is fundamental in Boolean expressions and is used to express the logical negation of a statement. This concept is essential for simplifying expressions and designing digital circuits.
What is the difference between a well defined set and not a well defined set?
A well-defined set has clear and unambiguous criteria for its membership, meaning that it is possible to determine whether any given element belongs to the set. For example, the set of all even numbers is well-defined because it follows a specific rule. In contrast, a not well-defined set lacks clear criteria, making it difficult to determine which elements belong to it; for instance, a set described as "all interesting things" is subjective and varies from person to person.
How do you factorise x squared - 81?
To factorize (x^2 - 81), recognize that it is a difference of squares. It can be expressed as ((x - 9)(x + 9)) because (81) is (9^2). Therefore, the factorization of (x^2 - 81) is ((x - 9)(x + 9)).
What is the gradient of the x axis?
The gradient of the x-axis is zero. This is because the x-axis is a horizontal line, and there is no change in the y-coordinate as the x-coordinate varies. Mathematically, the gradient (or slope) is defined as the change in y divided by the change in x. Since the change in y is zero along the x-axis, the gradient remains zero.
The point-slope form of a line is given by the equation ( y - y_1 = m(x - x_1) ), where ( m ) is the slope and ( (x_1, y_1) ) is a point on the line. Given the point (-2, -6) and a slope of 13, the equation becomes ( y - (-6) = 13(x - (-2)) ). Simplifying this, we get ( y + 6 = 13(x + 2) ).
How may degrees between hour 12 and hour 3?
On the analogue clock it is 90 degrees.
Astronomically, The Sun moves 45 degrees.
What is (2x - 5) (5x 9) simplified?
To simplify the expression ((2x - 5)(5x + 9)), apply the distributive property (also known as the FOIL method for binomials).
Now, combine the like terms: (18x - 25x = -7x).
Thus, the simplified expression is (10x^2 - 7x - 45).
Is 1 foot bigger or is 1 yard bigger?
1 yard is longer than 1 foot. (NOT bigger).
NB
Here is the Table of Imperial Linear Measure.
12 inches = 1 foot
3 feet = 1 yard ( The answer to your question).
22 yards = 1 chain (THe length of a cricket pitch)
10 chains = 1 furlong (furlong ; old English for furrows length ; ploughing a field).
8 furlongs = 1 mile.
What are easy ways to find out LCM and GCF?
Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
Select the highest amount of each factor.
2 x 3 x 5 x 7 = 210, the LCM
Check it.
30 x 42 = 1260
210 x 6 = 1260
It checks.
What is the area of a circle with radius 5.2cm?
Remember and commit to memory ' Area of a circle equals 'pi' multiplied to radius squared.
Algebraically
A = pi r^(2)
For learning purposes pi always equals '3.14'.
Hence
A = 3.14 X (5.2 cm)^(2)
A = 3.14 X 27.04 cm^(2)
A = 84.9056 cm^(2).
What is the radius of A equals 121 pi cm squared?
Remember the Area of a Circle equal 'pi' multiplied to radius squared.
Algebraically.
A = pi r^(2)
Hence
r^(2) = A/pi
r = sqrt(A/pi)
Substituting
r = sqrt( 121 pi / pi )
Cancel down by 'pi'
r = sqrt(121)
r = 11 cm
What polygons has the larger exterior angle?
A polygon with any number of sides can have an exterior angle that is larger than the corresponding interior angle. However, a triangle is the only regular polygon where the exterior angle is larger.
How do you get the number of sides of a regular polygon with a given exterior angle?
No. of sides = 360 / Exterior Angle.
e.g.
No. of sides for an exterior angle of 30 degrees.
No.(sides) = 360 / 30
No. of sides = 12. ( A Dodecagon.
What to the third power equals 6128?
To find what number to the third power equals 6128, you need to calculate the cube root of 6128. The cube root of 6128 is approximately 18.5. Therefore, around 18.5 to the third power is equal to 6128.
How many yards are in 127 feet?
Remember 3feet - 1 yard.
So 127 feet = 127/3 = 42 1/3 yards. or 42.333.... yards.
