Answer:
The section of a parabola that shows a falling curve with decrease in the y values of the graph is known as the decreasing interval of the quadratic function
Step-by-step explanation:
So first six sided polygon is called hexagon.
and the sum of all interior angles in a hexagon is 720°
so if you divide that by six. since it has six interior angles,
the angle of each interior angle will be 120°
as of exterior angle.
*note: the sum of the interior angle and its corresponding angle is always 180°
so if you subtract 120° from 180°
you have 60°
so all exterior angles are 60°
Answer: 165 ways
Step-by-step explanation:
The process of selection is done by using the combination formula for selection. If given "n" items and we are to choose "r" items from this given "n", the formula to use is denoted by:
nCr. = n! /(n-r)! × r!
Where
n! = n * (n-1) * (n-2)... *3*2*1.
In this case the number of items given = 11
And the number of items to be chosen = 3,
Hence the number of ways to do this = 11C3= 11!/(11-3)! × 3!
=165 ways.
Answer:
Angle DOC
Step-by-step explanation:
Since angle AOC and angle DOC are ajacent angles that form a straight line, they are supplementary to each other.
By the definition of supplementary angles, you can determine that angle AOC + angle DOC = 180.
Also notice that angle DOC is a right angle (90 degrees), so you can also determine that angle AOC is also a right angle since they are supplementary.
