The height, h, in feet, of an object dropped from the top of the Empire State Building can be estimated using the equation h= -1
Ksju [112]
To determine the height of the object after a certain time it is dropped, we simply substitute the time to the function given. We calculate as follows:

h = -16t^2 + 1454
h = -16(8^2) + 1454
h = 430 feet above the ground

Hope this answers the question. Have a nice day.

X^4-100=0 solve the equation by factoring
timurjin [86]
x^4-100=0 \\
(x^2)^2-10^2=0 \\
(x^2-10)(x^2+10)=0 \\
x^2-10=0 \ \lor \ x^2+10=0 \\
x^2=10 \ \lor \ x^2=-10 \\
x=-\sqrt{10} \ \lor \ x=\sqrt{10} \ \lor \ x=-\sqrt{-10} \ \lor \ x=\sqrt{-10} \\
\boxed{x=-\sqrt{10} \hbox{ or } x=\sqrt{10} \hbox{ or } x=-i\sqrt{10} \hbox{ or } x=i\sqrt{10}}
