Coolio
alright, so the disatnce formula is
solve for y in the equation given on top
2x+y-10=0
y=10-2x
ok
so (x1,y1)=(0,0), the first point
(x2,y2)=(x,10-2x)
so subsitute to get
find the miniumum
we only need to minimize what is under the square root so
take the derivitive of 5x²-40x+100
that is 10x-40
it is 0 at x=4
when x<4, the derivitive is negative
when x>4, the derivitive is positve
goes from negative to positive
so it is a minimum
at x=4
find y
y=10-2x
y=10-2(4)
y=10-8
y=2
(4,2)
find min distance
the point, P, is (4,2) and the minimum distance is 2√5
Okay so,
A (0.2875; 5), B (10; 39)
THE SLOPE IS 3.5
If they are all a foot long then she should have 32 pieces of Chain
8 feet 4 inches is more precise and easier to use.
It would be weird to say 7 feet 16 inches, because there's 12 inches in a foot and your already using that measurement.
Hope this is helpful:)
Answer:
Alice is 34
Step-by-step explanation:
71 - 4 = 68
68 ÷ 2 = 34
