For this case we have the following equation:
Where,
t: time
v: initial speed
s: initial height
Substituting values we have:
By the time the ball hits the ground we have:
From here, we clear the value of time:
Using the quadratic equation we have:
Doing the calculations we have:
Discarding the negative root, we have that the time is:
Answer:
it takes the ball to hit the floor about:
1.15 seconds

Solution ↓
The question is asking you turn this mathematical explanation to standard form.
Eight more: + 8
Three times a number: (3 * n)
Equals: =
Four less than a number: n - 4
---------------------------------------------------
Final Answer ↓
(3 * n) + 8 = n - 4

Hope this helped! Good Luck!
Answer:
y = 3^x is the answer as the others are quadratic or cubic functions.
Quadratic graphs are always pointing upwards or downwards, while cubic graphs have 1 end up and 1 end down.
-1
You put -1,5 on top of 6,-2 then u subtract so basically-1-6=-7 and 5- -2=7 so -7 over 7 you divide both by 7 to make it in simple form so it’s -1
