Answer 14

Lauren, what is the question that you are trying to answer?

Answer 15

she wanted to know which one of those fractions were equal. 3/4=15/20=75/100

Answer 16

to each other

Answer 17

duuuuuuuuuuuuuuuuuuuuuhhhhhhhhh

Answer 18

oh, so the 75/100 would be equal to 15/20?

Answer 19

YEEEEEEEEEEEEESSSSSSSSSSSS

Answer 20

K, sorry

Answer 21

lmaao , its ard girl(:

Answer 22

any more

Answer 23

do you think you could help me out with one of my word problems?

Answer 24

me ?

Answer 25

sure

Answer 26

yeah what

Answer 27

born ready !

Answer 28

ok, are you ready?

Lauren dove into a swimming pool from a 15-foot-high diving board with an initial upward velocity of 8 feet per second. Find the time t in seconds it took lauren to enter thh water. Use the model for vertical motion given by the equation:
h=-16t^2+vt+s, where h is height in feet, t is time in seconds, v is the initial upward velocity i feet per second, and s is the initial height in feet. (HInt: let h=0 represent the surface of the pool.)

Answer 29

oh my jesus . what grade are you in ?

Answer 30

im a freshman in high school. Algebra 1. Is this too hard for you?

Answer 31

haha . naah .

Answer 32

k, I learned how to do this last year because i was in algebra last year, but i failed. Anyway i have never remembered how to answer these type of questions

Answer 33

well , first think what exactly are they trying to ask you ? whats important in the problem and whats just gravy?

Answer 34

ok

Answer 35

Use the model for velocity motion given by the equation h=16t^2+vt+s, where
h is height in feet , t is seconds, v is the initial upward velocity in feet
per second, and s is the initial height in feet.
:
I think the equation should be h = -16t^2 + vt + s (-16t^2 is the downward force of gravity)
:
When the diver strikes the water, h = 0, therefore


-16t^2 + 8t + 15 = 0
Multiply by -1 and try to factor this
16t^2 - 8t - 15 = 0
(4t - 5)(4t + 3) = 0
Positive solution
4t = 5
t =
t = 1.25 seconds to hit the water

Answer 36

break it down.

Answer 37

so I need to know the height of the board and the upward velocity of 8 feet per second and i don't know what else

Answer 38

i kinda showed you up there right?

Answer 39

Oh my gosh, THank you so much

Answer 40

Yo kerianne23 I gave you a hint for that locker pellet if it helps. If you;re still there, and haven't solved it yet, check that out. If It doesn't help, get back to me!
