Answer:
It depends on what you are asked to do. See explanation.
Step-by-step explanation:
The height, h metres, of a particle at time, t seconds is given by the function:
h=(14-t)(t-2).
This means that after a given time, we can use this function to find the height of the particle.
For instance after 3 seconds, the height of the particle will be:
This implies that:
So after 3 seconds the height of the particle is 11 meters.
Answer:
Only option C: The shortest side can equal 7 cm.
Step-by-step explanation:
Let the length of the shortest side be x cm, then the length of the longest side is 4x cm. Let the length of the middle side be y cm. Note that
The perimeter is
A. The value x cannot be 40 cm, because then y is negative
B. If the longest side is 30 cm long, then
But
This means that such triangle does not exist
C. If x=7 cm, then 4x=28 cm,
Since,
such triangle exists and this option is possible
D. If x=25 cm, then y is negative
E. If x=5 cm, then 4x=20 cm and
But this triangle does not exist, because
