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

Answer:
The answer to your question is there are 440 students
Step-by-step explanation:
Data
110 girls = 25% of the total students
The Total number of students = ?
Use a rule of three to solve this problem
110 girls ---------------------- 25%
x ----------------------- 100%
x = (100 x 110) / 25
x = 440 students
