Answer:
after 2 seconds
Step-by-step explanation:
We want to find t such that h = 0.
0 = -16t² +8t +48
0 = 2t² -t -6 . . . . . . . divide by -8
0 = (t -2)(2t +3) . . . . factor
The only positive solution is t = 2, which makes the first factor zero.
Stella will land in the water at t = 2 seconds.
Seven Hundred Twenty is the correct answer.
Answer:
Step-by-step explanation:
18y -30 -7y =25
solution
18y -30 -7y =25
so we take like terms that is unknown to unknown whole number to whole number or you can put it this way to remember(brothers go to brothers are the ones with an alphabet , sisters go to sisters they are the ones without an alphabet numbers)......okay lets continue
18y -7y=25+30
when a negative is crossing an equal sign it turns positive and vice versa
so lets solve
11y=55
the one with the unknown will divide
11y/11=y
you cant say 1y its wrong in maths you can say in another subject but not maths....okay...so we say y the 1 is invisible but you can say 2y ,3y etc
Then 55/11=5
so y=5
Thats the correct answer....
