Answer:

The correct option is 4.

Step-by-step explanation:

Domain is the set of all possible inputs for which the given function is defined.

The given function is

y=x^2-6x+1

It is a second degree polynomial. These type of polynomial are defined for all real values of x. So, the domain of the given function is all real numbers.

Domian=\{x:x\in R\}

Domian=R

Therefore the correct option is 4.

Match each power of a power expression with its simplified expression.
VARVARA [1.3K]

Answer:

> (4^6)^{-3} = \frac{1}{4 ^ {18}}

> (4^{-3})^{-3} = 4 ^ 9

> (4^0)^{-9} = 4 ^0

> (-4^{-9})^2 = (-4) ^ {-18}

Step-by-step explanation:

We have to expand the powers of each of them:

> (4^6)^{-3} = 4^{(6 * -3)}

          = 4 ^ {-18}

(4^6)^{-3} = \frac{1}{4 ^ {18}}

> (4^{-3})^{-3} = 4 ^ {(-3 * -3)}

  (4^{-3})^{-3} = 4 ^ 9

> (4^0)^{-9} = 4 ^ {(0 * -9)}

  (4^0)^{-9} = 4 ^0

> (-4^{-9})^2 = -4 ^ {( -9 * 2)}

  (-4^{-9})^2 = -4 ^ {-18}

Since the order of selection does not matter, we will use combinations to solve this problem.

We are to form the combination of 30 objects taken 6 at a time. This can be expressed as 30C6.

30C6= \frac{30!}{6!*24!}  \\  \\ 
= 593775

This means the six teachers can be selected in 593775 ways.

So the correct answer is option A
