THIRD TIME I ASKED n object was shot up into the air with an initial vertical speed of 544 feet per second. Its height as time passes can be modeled by the quadratic equation y = -16t^2+ 544+. Here t represents the number of seconds since the object's release, and y represents the objects height in feet a. After (blank), this object reached its maximum height of (blank)

b. This object flew for (blank) before it landed on the ground.

c. This object was (blank) in the air 22 s after its release.

d. This object was 3600 ft high at two times: once (blank) after it's release, and again later (blank) after it's release. ​

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
