Find the magnitude of ab with initial point a(3,-1) and terminal point b(-2, 6).

The magnitude of AB with initial point A(3,-1) and terminal point B(-2, 6) is 8.6 units.

The distance between two points A(x₁, y₁) and B(x₂, y₂) on the Cartesian plane is given by:

Given AB has initial point A(3,-1) and terminal point B(-2, 6), The magnitude of AB is:

Step-by-step explanation:

AB=√(-2-3)²+(6+1)²=√(25+49)=√(74)

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
