oh my god, that was the exact homework i had few days ago, but you have to have a calculator to do this. just plug in the numbers in the but ton Y=, one column you put-16t squared plus 25t plus 6 then the next column you put 0. the graph should form a parabola.
S=vt-16t2 solve for v is what I will assume you mean. first pull out the t S=t(v-16t) then devide by t S/t=v-16t Then add 16t to both sides S/t + 16t = v This can also be written as (S+16t2)/t = v
formula: h=-16t^2+vt+s H= final height T= time V= velocity S= starting height
d = -(1/2)g*t^2 v = - g*(squareroot(2(d/g))) wrong the real formula is: h=-16t^2+s h= ending height usually 0" t=time s= starting height (example) 0=-16t^2+256 -256 -256 -256=-16t^2 __________ -16 16=t^2 t=4 seconds They're both the same formula, they are just transposed. The ending height is always zero since you want the intermittent distance and time of that distance. d = -(1/2)g*t^2 =-(1/2)(32)*t^2=-16*(t^2)
If the arrow was fired in a direction making an angle x with the horizontal, and assuming that acceleration due to gravity is 32 feet per second^2 ijn the downward direction, then its height at time t iss(t) = 160*sin(x)*t - 16*t^2.

16t plus 7 equals 19t plus 10. 16t+7=19t+10. Subtract 16t and 10 from both sides. -3=3t -1=t

Yes.
100t -16t2 = 0 t4(25-4t) = 0 t = 0 or t = 25/4
16t(t + 4) is the factorization Usually it's set = to 0 16t (t+4) =0 So, either 16t = 0 or t + 4 = 0 t = 0 or t = -4
It has no solutions because the discriminant of b2-4ac is less than zero
h=-16t^2-80t+200 200=-16t^2-80t+200 200-200=-16t^2-80t+200=200 0=-16t^2-80t 0=-16t(t+5) 0=-16t OR 0=t+5 t=0 OR t=-5 put the answers back into the original equations to see which one(s) work, and next time, ask your teacher or prof. for help on your physics/calc hw.
You could divide each side by 't' to get 9t2=16 , then divide each side by 9 to get t2=16/9 , then take the square root of each side to get t=(plus or minus) 9 . That would give you two of the three solutions that you know a 3rd degree equation must have. You could look back at your original equation, scratch your chin for a moment, and realize that t=0 is also a solution.
d = 16t² t = 1 s → d = 16 × 1² = 16 × 1 = 16 ft
√ (16t) =√ 16*√ t = 4*√ t
