yaroslaw [1]

Answer:

$d=\sqrt{13}\ units$ or $d=3.61\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-5,1)\\E(-2,3)$

substitute the values

$d=\sqrt{(3-1)^{2}+(-2+5)^{2}}$

$d=\sqrt{(2)^{2}+(3)^{2}}$

$d=\sqrt{13}\ units$

$d=3.61\ units$

Answer:

15%

Step-by-step explanation:

we call the original price 100% and to find the discount amount :

Multiply 100 by $476 then divide by $560

100 × $476 ÷ $560 = 85

$476 is 85% of the original price therefore the amount of discount as in percentage is 100 - 85 = 15%
