Answer:The approximate square root is 2.23
Step-by-step explanation:√ 5 = 2.23
Thus: 2.23 x 2.23 = 5
For the first one its (-4,0) and (3,0)
For the second one its (3,5) , (3,0) and (6,0)
All the points if they lay on top of eachother
if they arent on top of eachother, they can intersect at 2 points
Answer:
Step-by-step explanation:
Given the following :
Laps - - - - - - - - 5 - - - 6 - - - 7 - - - 8 - - - 9
Total time - - - 25 - - 28 - - 29 - - 30 - - 32
Using online graphing tool:
The y - axis named dependent variable represents the total time taken.
The x-axis, represents the number of laps.
The equation of the trend line attached to the plot is in the form :
y = mx + c
y = 1.6x + 17.6
Where y = total time taken
x = number of laps
m = 1.6 = gradient of the line (change in y / change in x)
C = 17.6 = intercept (whee the trndline intersects the y-axis).
