Answer:
time taken = 2.74 seconds
Explanation:
We are given that:
y = -16t² + 120 models the situation where:
y is the floor number
t is the time taken for the apple to hit the ground
We are also given that the floor number (y) is 10. Therefore, all we have to do is substitute with y in the above equation and solve for the time t as follows:
y = -16t² + 120
10 = -16t² + 120
120 - 10 = 16t²
110 = 16t²
t² = 110/16
t = ±√6.875
either t = 2.74 seconds ..........> accepted
or t = -2.74 seconds .........> rejected as time cannot be in negative
Hope this helps :)

Answer:
4x -2 = 3 and 4x + -2 = 3
Step-by-step explanation:
-2 + 4x = 3 ---- 4x -2 = 3 ------------ 4x + -2 = 3
+2 +2 - 2 +2
------------------ ----------------
4x = 5 4x = 5
