Find a point on the y-axis such that its distance from the point (8,5) is 10 units.

Given:

The point is (8,5).

To find:

A point on the y-axis such that its distance from the point (8,5) is 10 units.

Solution:

Let the required point on the y-axis be (0,k).

Distance formula:

The distance between (8,5) and (0,k) is 10 units. Using distance formula, we get

Taking square on both sides.

Taking square root on both sides.

Now,

and

and

and

Therefore, the required point is either (0,11) or (0,-1).

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
