Answer:

±16

The principle value is 16

Step-by-step explanation:

sqrt(8) * sqrt(32)

We know that sqrt(a) sqrt(b) = sqrt(ab)

sqrt(8*32)

sqrt(256)

sqrt(16*16)

±16

The principle value is 16

17st - 16s + t =<br><br> I NEED HELP

Arisa [49]

It has to be in alphabetical order so, -16s + 17st + t I believe. If it’s incorrect, that’s because we’re barely learning it, sorry.

frozen [14]

Area, A = Width, W* Height, H

Therefore,
W = A/H

Options:
At H = 4 ft, W = 60/4 = 15 ft
At H = 5 ft, W = 60/5 = 12 ft
At H = 6 ft, W = 60/6 = 10 ft

What is the inverse of function f? F(X) = square root of x +7

katrin2010 [14]

Answer: $f^{-1} (x)=x^{2} -7$

Step-by-step explanation:

To find the inverse of a function replace f(x) with x and the original x with y

$f(x)=\sqrt{x+7} \\x=\sqrt{y+7}$

Now we can solve for y

Square both sides so we can cancel out the root

$x=\sqrt{y+7}\\x^{2} =\sqrt{y+7}^{2} \\x^{2} =y+7$

Now subtract 7 from both sides

$x^{2} =y+7\\x^{2} -7=y+7-7\\x^{2} -7=y$

Now replace y with the inverse of f(x), $f^{-1} (x)$
