f(x) = 2x - 7 This should be the answer!!
Yes I worked it in my brain hahahahahah
Answer:
2 secs after
Step-by-step explanation:
Given the height of the object modeled by the eqaution;
H(t) = 32T - 16T² where;
T is the time in seconds
The object hits the ground when h(t)= 0
Substitute H = 0 into the equation and get t as shown;
0 = 32T - 16T²
0-32T = -16T²
-32T = -16T²
32T = 16T²
32 = 16T
T = 32/16
T = 2secs
Hence the object hits the ground after 2 secs
It depends on how it's used.
For example if it's angles it could be because of Vertical Angles.
If it's Triangles it could be Definition of Congruent Triangles.
