(4-1/2) Please answer the questions and solve this quadratic equation which is very similar to the one we did earlier in the week: A goalkeeper threw a ball from the ground to a defender to work up the pitch. Here is the equation that models this situation: -16t2 + 32t

What does the "a" coefficient represent in this type of quadratic equation?

What does the "b" coefficient represent in this type of quadratic equation?

If the units of the equation are feet per second, what do you think the "y" axis represents? The "x" axis?

How many seconds will it take for the ball to hit the ground?

g

step-by-step explanation:

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.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

answer: what statements

step-by-step explanation if you write the statements down then i could you.
