The slope of that line is 1/3 , as y=mx+b , where m is slope
Answer:
2
Step-by-step explanation:
slope = (y2 - y1) / (x2 - x1)
(1,8)...x1 = 1 and y1 = 8
(3,12)...x2 = 3 and y2 = 12
now we sub
slope = (12 - 8) / (3 - 1) = 4/2 reduces to 2 <===
t = 5.05 sec
Solution:
Given data:
Initial height = 24 meter
Initial velocity = 22 meter
Height of the rock (h) = 10 meter
To find when will the height of the rock be 10 metres:
General formula for the height(meter) of a projectile over time:
Substitute the given data in the above formula.
This equation looks like a quadratic equation.
We can solve it by using the quadratic formula:
Here a = –4.9, b = 22, c = 14
Time cannot be indicated in negative. So neglect t = –0.56.
Therefore, t = 5.05 sec
Hence after 5.05 sec the rock will be 10 meters from ground level.
Inverse operations are pairs of mathematical manipulations in which one operation undoes the action of the other
