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.

The reciprocal is flipping it over and making the denominator which is 5 the numerator. So just switch the top and bottom numbers to get 5/3.

Find the distance between R(-5,-3) and S(4,-2).

harina [27]

Answer:

√106

Step-by-step explanation:

to calculate the distance between two points on an xoy plane you use the formula

√(x2-x1)²+(y2-y1)²

in this case x1 is -5,x2 is 4,y1 is -3 and y2 is -2 therefore the solution will be

√(4-(-5)²+(-2-3)²

√(4+5)²+(-5)²

√(9)²+(-5)²

√81+25

√106

I hope this helps
