Endpoints of the segment line:
H ( 6, 4 ) and K ( 2, 8 ):
x 1 = 6, x 2 = 2;
y 1 = 4, y 2 = 8:
x m = ( 6 + 2 ) / 2 = 8 / 2 = 4
y m = ( 4 + 8 ) / 2 = 12 / 2 = 6
Answer: D ) ( 4, 6 )
Answer: Second option.
Step-by-step explanation:
As you can observe in the picture given in the exercise, there are two Right triangles formed inside the rectangle: CDA and ABC.
You need to use the Pythagorean Theorem to solve this exercise. This is:
Where "a" is the hypotenuse and "b" and "c" are the legs of the Right triangle.
If you solve for one of the legs, you get the following equation:
In this case, you can identify in the figure that:
Finally, you must substitute these known values into the equation and then evaluate in order to find the value of "x". You get that this is:
The multiplicative identity anything x 1 is the anything
X = 6, representing the straight line parallel to y-axis at a distance 6 units from the axis
x = r cos
θ
.
Answer:
Associative Property
Step-by-step explanation:
When the order of operands remains the same, all operations are identical (multiplication, or addition), and only the parentheses change places, the property involved is the <em>associative property</em>.
