Use the table below to fill in missing values.
aliina [53]

Step-by-step explanation:

We can observe from the table that the value of independent variable and then the values of function on that variable are given.

So,

<u>f(5) = 6</u>

As the value of function at x=5 is 6

<u>If f(x) = 4 then x = 7</u>

The value of function is 4 only on x=7 so the answer is x = 7

When the inverse is taken, the inputs become output and the outputs become inputs

f^{-1}(6) = 5

The value of inverse will be 5 because in original function 5 is input and 6 is output when this will be reversed for inverse, the output will be 5 for 6

Now,

Lastly

if\ f^{-1}(x) = 7,\ then \x = 4

The reverse rule of input and output will be used. The reverse function will generate 7 at input 4.

Simplify the expression shown. You must show your work to receive credit.
ZanzabumX [31]

ANSWER

12 \sqrt{5}

EXPLANATION

The given expression is

\sqrt{2}  \times  \sqrt{72}  \times  \sqrt{5}

The middle radical contains a perfect square.

\sqrt{2}  \times  \sqrt{36 \times 2}  \times  \sqrt{5}

\sqrt{2}  \times  \sqrt{36}   \times  \sqrt{2} \times  \sqrt{5}

6\sqrt{2}  \times  \sqrt{2} \times  \sqrt{5}

Note that:

\sqrt{a}  \times  \sqrt{a}  = a

6\times 2 \sqrt{5}  = 12 \sqrt{5}

Which answer describes the type of sequence? 3,4,5,6,...
In-s [12.5K]

Answer:

Arithmetic Sequence

Step-by-step explanation:

we know that

In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant, and this constant is called the common difference

we have

3,4,5,6,...

Let

a_1=3\\a_2=4\\a_3=5\\a_4=6

a_2-a_1=4-3=1

a_3-a_2=5-4=1

a_4-a_3=6-5=1

so

the difference between one term and the next is a constant

The common difference is equal to 1

This is an Arithmetic Sequence
