That depends if the line is vertical or horizontal. If the line is vertical, the slope (steepness) of the line is undefined (this is because the x values across the entire line are the same). If the line is horizontal, the slope of the line is 0 (this is because the y values will always subtract to equal 0 when you use the form y1 - y2/x1 - x2 to find slope).
Hope this helps.
Answer:
10 kph
Step-by-step explanation:
Find the speed of the current of the river.
20/(20 - c) + 180/(20 + c) = 8
20(20 + c) + 180(20 - c) = 8(400 - c^2)
8c^2 - 160c + 800 = 0
8(c^2 - 20c + 100) = 0
8(c - 10)^2 = 0
c = 10
The speed of the current of the river is 10 km/hour.
The removal of the lowest round will affect the median, by changing it from 92 to 93, and the mean from 90.4 to 93
Answer:
<ABC = 90 DEGREE
Step-by-step explanation:
Given that ,
Height at which kite is flying = 60 m
Let's make AB = 60 m
Also , inclination of the string with the ground = 60 degree
Hence , <ACB = 60 degree
We have to find length of sting , i.e., AC
Here , AB is perpendicular to the ground
So , <ABC = 90 degree
