the point 3,2 lies on a circle.what is the exact length of the radius of this circle if the center is located at (-1,-4)
Crazy boy [7]
You can use the distance formula to solve this.

Distance Formula:
d = \sqrt{(X_2 -X_1)^2 + (Y_2 - Y_1)^2}

I am going to use point (3,2) as point 1 and (-1,-4) as point 2
Insert the points into the formula
d = \sqrt{(X_2 -X_1)^2 + (Y_2 - Y_1)^2}
d = \sqrt{((-1) - 3)^2 + ((-4) - 2)^2}
Solve:
d = \sqrt{((-1) - 3)^2 + ((-4) - 2)^2}
d = \sqrt{(-4)^2 + (-6)^2}
d = \sqrt{16 + 36}
d = \sqrt{52}
d = \sqrt{52} = \sqrt{4}\sqrt{13}
d = \sqrt{52} = 2 \sqrt{13}
d = 2 \sqrt{13}
radius = 2 \sqrt{13} = 7.2111

The Ray family went out to dinner The price of the meal was $38.95 The sales tax was 7% of the price of the meal. The tip was 18
Andrews [41]

Answer:

$49.18

Step-by-step explanation:

Dinner cost $38.95 before tax and tip are included.  

Directions say to ADD 7% tip first so,

38.95 multiplied by 7%= 2.7265, Round up to $2.73

ADD $38.95 and $2.73 tax= $41.68

Now, multiply $41.68 by 18% to find the tip amount

$41.68 * 18%= 7.5024, Round to $7.50

ADD $41.68 and $7.50 to get answer: $49.18
