GIVING BRAINLIST PLEASE HELP An arrow is shot straight up from the roof of a 60-ft tall building with an initial velocity of 68 ft/sec. The height of the arrow is given by:
h(t) = -16t^2 + 68t + 60

where h(t) is the height, in feet, and t is time, in seconds. At what time or times will the arrow be 112 feet off the ground. Round your answer to the hundredths place, if necessary.

Down Below

Step-by-step explanation:

h=height =60

112ft will be at 1 second and 3.25 seconds

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
