The distance formula is: d = sqrt( (x2 - x1)2 + (y2 - y1)2 )
For this problem, let (-5, -4) be the "first" point, so x1 = -5 and y2 = -4
and let (-6, 4) be the "second" point, so x2 = -6 and y2 = 4.
Then: d = sqrt( (-6 - -5)2 + (4 - -4)2 ) = sqrt( (-1)2 + (8)2 ) = sqrt( 1 + 64 ) = sqrt( 65)
The distance formula is just the Pythagorean Theorem applied to an x-y graph.
You would get the same final answer if you let (-5, -4) be the second point and (-6, 4) be the first point.
Answer: The number of ways would be 36,036.
Step-by-step explanation:
Since we have given that
Number of white light bulbs = 5
Number of orange light bulbs = 6
Number of blue light bulbs = 2
Total number of light bulbs = 13
So, the number of distinct orders of light bulbs if two bulbs of the same color are considered identical.
Hence, the number of ways would be 36,036.
Answer:
Y=7 and
X=9
Step-by-step explanation:
X+Y=16
X=2+Y
2+Y+Y=16
2+2Y=16
2Y=16-2
2Y=14
2Y/2=14/2
Y=7
X =2+Y
So X=9
Answer: 3
Step-by-step explanation: Hope I helped
By definition we have that the perimeter of a rectangle is given by:
P = 2b + 2h
Where,
b: base
h: height
Also, as a data of the problem we have:
base is two times the height:
b = 2h
Substituting we have:
P = 2 (2h) + 2h
Clearing h:
6h = P
h = P / 6
h = (80x) / 6
h = (40/3) x
The base will be
b = 2h
b = (80/3) x
Answer:
the dimensions of the rectangle are
b = (80/3) x
h = (40/3) x
b. h = 13.3x; b = 26.6x
