Negative 0.9 = -0.9
Negative 0.09 = -0.09
Negative 0.99 = -0.99
From least to greatest:
-0.99, -0.9, 0.09
It's the same as:
-99/100, -90/100, -9/100
The closer to zero, the greater the number is.
A ball is thrown from an initial height of 2 meters with an initial upward velocity of 9/ms
Balls height
To find all values of t for which the ball's height is 3 meters
We plug in 3 for h and solve for t
Solve for t
Solve using quadratic formula
After simplifying this,
= 0.11898
= 1.68102
the values of t for which the ball's height is 3 meters= 0.12 sec , 1.68 sec
