Task 4: A carnival attraction tests your strength by how far in the air

you can drive a weight with a hammer. If the weight

reaches 15 feet you win a prize! The equation

h = -1612 + 317 + 2 gives the height h of the weight t seconds

after you hit it.

A: How long is the weight moving?

B: What was the weight's maximum height?

C: Did you win a prize? How do you know?

B i think i am sorry if it is not right but i am pretty sure i am right tho

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.

answer: 1+1

step-by-step explanation: 1+1 is at least 2
