3:2 because they all are dividable by 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.
Answer:
Student 1.
Step-by-step explanation:
Okay, for this one, for it to be linear, the x has to be adding or subtracting the same amount each time (same goes for y). You have to remember that the x and y do not correspond, only the sides themselves. As you can tell, Student 1 goes up by 1 on the x side each time, and on the y side, it goes up by 5 each time. The other graphs don't have linear equations. I hope this helped, if you need me to evaluate more, just ask!
