Ray Guy, the Oakland Raiders punter, holds the record for the longest "hang time" (the amount of time the football stays in the
air) for a punt in the National football League (NFL) at 8 seconds.
is considered a good punt if the "hang time" lasts longer than 4.5
seconds.
If a punter kicks a football with an upward velocity of 70ft/sec
and his foot meets the ball at 3 feet above the ground, the
function h(x) = -16x + 70x + 3 represents the height of the
ball h(x), in feet, after x seconds.

step-by-step explanation:

it has the same slope and a different y-intercept

hope this : )

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
