The height in feet of an object projected upward as a function of the elapsed time in seconds since it was launched can be represented by the formula shown below. h(t) = –16t2 + v0t + h0 In the formula h(t) is height in feet; t is time in seconds; v0 is the initial velocity; and h0 is the initial height. An object is projected upward with an initial velocity of 50 feet per second from a starting height of 9 feet. When will the object hit the ground?

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

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.
