Is the quotient of 3.6 divided by 9 greater or less than 1?

Kisachek [45]

Answer:

Step-by-step explanation:

The given quotient is

$\frac{3.6}{9}$

In this case, before solving the quotient, we can ensure that its result is less than 1, because the numerator is less than the denominator, this is called a "proper fraction", and those fraction always ends in a number less than 1.

$\frac{3.6}{9}=0.4$

Therefore, the answer is "less than 1".

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), $f^{-1} (x)$
