A stunt motorcyclist makes a jump from one ramp 20 feet off the ground to another ramp 20 feet off the ground. The jump
between the ramps can be modeled by y = -640*+ ** +20 where x is the
horizontal distance in feet) and y is the height above the ground (in feet).

a. What is the motorcycle's height r when it lands on the ramp?
b. What is the distance d between the ramps?
c. What is the horizontal distance h the motorcycle has traveled when it
reaches its maximum height?
d. What is the motorcycle's maximum height k above the ground?

pls ask

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
