8n - 4
Step-by-step explanation:
The numbers here go up in 8, so you have 8n. Afterwards, use the term and the 8 times tables. Eg. 4 is the first term and the first 8 multiple is 8, so 4-8. You have to subtract 4 from 8 to get the first term. Sorry if this didn't help but yeah...
Answer:
x = - 4
Step-by-step explanation:
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:
