Multiply eight and eighty-eight hundredths by two and three tenths
zimovet [89]

Answer:

20.424

Step-by-step explanation:

Given words can be written as

Eight and eighty-eight hundredths = (8+\frac{88}{100})

                                                            = \frac{800+88}{100}

                                                            = 8.88

Two and three tenth = (2+\frac{3}{10})

                                   =  \frac{20+3}{10}

                                   =  2.3

Now multiply them

i.e 8.88 × 2.3 = 20.424

So 20.424 is the Answer

Use the graph of f below. Assume the entire function is graphed below.<br> Find the domain
enot [183]

ANSWER

The domain of the function is

- 3 \leqslant x \leqslant 6

or

[-3,6]

EXPLANATION

The domain of a function refers to the values of x for which the function is defined.

From the graph, we can see that the function begins at (-3,6) and ends at (6,-4).

Therefore the function is defined for x=-3 to x=6.

Hence the domain of the function is

- 3 \leqslant x \leqslant 6

or

[-3,6]
