The two are perpendicular to each other because the two slopes are negative reciprocals
(Y2 - Y1) / (X2 - X1)
First slope:
( 1 - (-1)) / (-11 - (-6))
2/-5
Second slope:
(-13 - (-8)) / (-5 - (-3))
-5/-2 or 5/2
You know when two aliens are perpendicular when you multiply the two slopes and get -1 as the product
-2/5 X 5/2 = -1
Thus the two lines are perpendicular to each other.
Answer:
k x 1/2
Step-by-step explanation:
because k x 1/2 = k/2
Answer:
5 Degrees
Step-by-step explanation:
In order to find the median, you must put the temperatures in ascending order. The median is the number in the middle.
This week
65 71 73 73 73 74 75
Last Week
51 62 66 68 72 72 85
The median of This week is 73 while the median last week is 68.
73-68=5 degrees
Step-by-step explanation:
3.38 × 
is the scientific notation of 3,380,000
Multiply the numerator by the numerator (top number).
Multiply the denominator by the denominator (bottom number).
So 3 x 6 = 18
And 5 x 7 = 35
= 18/35
