A quarterback throws an incomplete pass. The height of the football at time t is modeled by the equation h(t) = â€"16t2 40t 7. Rounded to the nearest tenth, the solutions to the equation when h(t) = 0 feet are â€"0. 2 s and 2. 7 s. Which solution can be eliminated and why? The solution â€"0. 2 s can be eliminated because time cannot be a negative value. The solution â€"0. 2 s can be eliminated because the pass was not thrown backward. The solution 2. 7 s can be eliminated because the pass was thrown backward. The solution 2. 7 s can be eliminated because a ball cannot be in the air for that long due to gravity.

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
