The Distance between the coordinates of two points is measured by distance formula.
Step-by-step explanation:
The Distance between the coordinates of two points P(x1,y1) and Q(x2,y2) is measured by
Distance PQ=
(x2-x1)²+(y2-y1)²
So, the distance between (-1,4 ) and (2,0) can be calculated by
Distance=
(2-(-1))²+(0-4)²
=
(3)²+(-4)²
=
9+16 =
25 as
25 = 5
Distance = 5
So the distance between the two coordinates is 5.
Answer: Final price of the coffee table is $98.9.
Step-by-step explanation:
Original price of a coffee table = $115
Discount on a coffee table = 20%
So, After discount, it becomes,

Rate of sales tax = 7.5%
So, after tax the price becomes,

Hence, final price of the coffee table is $98.9.
28/45 or as a decimal 0.62
