Answer:
Option 3.
Step-by-step explanation:
The given function is

where, h(t) is the height of a small rock falling from the top of a 124-ft-tall building and t is the time in seconds.
It is a downward parabola.
Equate the function equal to 0, to find the time at which the rock touch the ground.

If
, the according to the quadratic formula

Using quadratic formula, we get



Time cannot be negative. So, the rock remain in the air in the interval 0 < t < 2.
Therefore, the correct option is 3.
No. Age function has nothing to do with height. A five foot man could be ninety three, or a five year old boy could be four feet tall. Age and height have nothing to do with each other.
Answer:

Applying cross multiplication:



The exchange rate for Dollars to Euros is of 1.33.
Answer:
m = -52
Step-by-step explanation:
Multiply by 4 on both sides:
m/4 = -13
4(m/4) = (-13)4
m = -52
A triangle's angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the third angle to make a 180 angle
