4 $\sqrt{3}$

Step-by-step explanation:

Use cosine to find y:

cos(60) = y/8 $\sqrt{3}$

solve for y:

y = 4√3

Hope this helps!

Use k as the constant of proportionality to write the equation expressing the relationship: y varies inversely as x.

"Inversely" generally means the relationship is proportional to the reciprocal.
y = k/x

2) 13.2607 Round the above number to th

NARA [144]

Answer:

For number two, nearest whole number is 13. nearest hundredth is 13.26. number three I don't see anything.

Step-by-step explanation:

Explanation: When rounding, u look at the right number and if

greater than 4, round up which is add one

if right number is 4 or less we take nothing. also we change all other numbers behind the left number to 0. so round to a whole number it would be 13. 2 is smaller than 5. Nearest hundredth is the same thing. we look at the hundredth place which is 6. We look to the right. it's 0. less than 5 we round down. so it would be 13.2600. Or 13.26

number 3 I don't see anything so I can't help out

Answer:

The vertex is at (-1,-7).

The answer to 2 is A.

Step-by-step explanation:

<h3>1st of all, for the vertex:</h3><h3 />

You want to make the absolute value be |0|, and you make that by assuming a x that is the opposite of the number that accompanies it.

In this case:

$|x + 1|$

Because:

$|( - 1) + 1| = 0$

Then:

$x = - 1$

And, by making the absolute value equal 0 when finding x, you're left with:

$y = - 7$

<h3>Secondly, for the domain and range question:</h3>

The easiest way is to graph, or make a table of values and see where the graph points.

I graphed it for you.

You can clearly see how the vertex, at (-1,-7) is the lowest point, telling you that the range is from that point upwards, or

$y \geqslant - 7$

Then, because you're dealing with absolute values, which never bend and make perfect 90° angles at their vertex, it is safe to assume both lines never touch and continue to opposites ends of the x-axis, or (-infinity, infinity) which is your domain.
