You can use the distance formula
Sqroot((x2-x1)^2 + (y2-y1)^2)
(2,-1) and (5,3), use given points
Sqroot((5-2)^2 + (3-(-1))^2)
Sqroot((3)^2 + (4^2)
Sqroot(9+16) = squareroot of 25
Squareroot of 25 = 5
Solution: D. 5 units
Well 1 package=3, so if she buys 5 packages it's 5*3=15. She still has 2 left so you take 15+2=17. She will have 17 juice boxes in total.
Answer:
R: √(13)
Step-by-step explanation:
Distance formula:
r^2 = (x-h)^2 + (y-k)^2
Center: (h,k)=(-1,5)
Circle: all points of (x,y)=(-3,2)
r^2=(-3+1)^2 + (2-5)^2
r^2=(-2)^2 + (-3)^2
r^2= 4 + 9
r^2=13 ((r^2)^(1/2)) = 13^(1/2) = 3.6055
Answer:
If he is traveling over 85 miles its cheaper to use company a
Step-by-step explanation:
137-65= 72
72÷0.85= 84.7058823529= 85
So after 85 miles company A is cheaper
