The main cable of a suspension bridge forms a parabola modeled by the equation y = a(x – H)2 + k where y is the height in feet of the cable above the road, x is the horizontal distance in feet from the right bridge support, a is a
constant, and (h, k) is the parabola's vertex. What is the maximum and minimum height of the bridge modeled by the
equation y = 0.005(x - 60)2 + 8?
O maximum height = 100 feet and minimum height = 26 feet
O maximum height = 100 feet and minimum height = 8 feet
O maximum height = 60 feet and minimum height = 26 feet
O maximum height = 26 feet and minimum height = 8 feet

D) maximum height = 26 feet and minimum height = 8 feet

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
