A toy falls from a window 80 feet above the ground. How long does it take the toy to hit the​ ground?
andrew11 [14]

Answer:

2.24 s

Step-by-step explanation:

Given:

Δy = 80 ft

v₀ = 0 ft/s

a = 32 ft/s²

Find: t

Δy = v₀ t + ½ at²

80 ft = (0 ft/s) t + ½ (32 ft/s²) t²

t = 2.24 s

PLS HELP<br> If f(x) = x2 -1, what is the equation for f–1(x)?
Anon25 [30]

We have a function,

f(x)=x^2-1

and we are asked to find its inverse function.

An inverse function essentially gets you the original value that was dropped into a function.

For example,

If I put 5 into f(x) I will get 24. Now If I take 24 and put it into the inverse function I have to get number 5 back.

The way to determine the inverse function swap the x and the f(x), then solve for f(x),

x=f(x)^2-1

f(x)^2=x+1

f(x)=\pm\sqrt{x+1}

Of course the notation demands that the obtained function be called,

f^{-1}(x)=\pm\sqrt{x+1}

Hope this helps :)
