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
t² = 6.875
either t = 2.74 seconds ..........> accepted
or t = -2.74 seconds .........> rejected as time cannot be in negative
Hope this helps :)
It’s =X+ and that’s ru answering
EDITED:
so lets make the question more clear
lets make it like this, if were gonna make 10 = b vv (sorry I meant to say 10, but I said 6 ;-;
3(10) - 4 + 6(10-9) = 30 - 4 + 6 = 26 + 6 = 32
= THIS EQUALS 32
Now lets do 9(b-6) - 4 which will be turned into 9(10-6) - 4 = 36 - 4 = THIS EQUALS 32
MY ANSWER IS YES (DONT ASK ME WHY IM WRITING IN CAPS (((: )
