Which ordered pair represent a function

sweet [91]

Answer:

The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates. The second example is not a function, because it contains the ordered pairs (1,2) and (1,5).

Hope this helps you with your question.

Find the reciprocal of 3/5

Kisachek [45]

The reciprocal of 3/5 is 5/3.

To get the reciprocal of a fraction, just turn it upside down.

A fraction has a numerator, top number, and a denominator, bottom number.
To get the reciprocal of a fraction, just swap over the numerator and denominator.

If whole numbers, to get the reciprocal of whole number, just divide the whole number by 1 to make it into a fraction, then get the reciprocal of that fraction.

Can u help with these two

Artemon [7]

The volume of a rectangular prism can be given by the form
$V= b*h*w$

you know Volume, base, and height but you dont know width

so divide b and h to both sides
$\frac{V}{b*h} = w$
and you cna solve for width

now for 6.
dividing by a number is the same as multiplying by its reciprocal

$n \div 6 = n * \frac{1}{6}$

Explain how to write 1.25 times 10 to the negative third power in standard form

OleMash [197]

This is called "Scientific Notation"

$1.25 \times {10}^{ - 3}$
So you will always see the 10... Don't worry about it but worry if it is negative or positive because the sign will determine how to move the decimal point.

So, since it is negative then we will be moving the decimal point to the left. And, if it was a positive 3 then we'd move the decimal point to the right!

We will be moving it to the left "3" times because it says - 3 not - 5, etc...
$1.25 \times {10}^{ - 3} = 0.00125$
So just move the decimal 3 times in this case and there you go, your standard form. I forgot what the other form is but I can still solve for it...

I hope this helped if you have any questions then feel free to ask!!
