4.7 because if you plug it in- (2,1) and (6,6) it is 4.7 units
Answer:
-19x
Step-by-step explanation:
-6 / 2 = -3 so
x^2 - 6x + 8 is
(x - 3)^2 -9 + 8
= (x - 3)^2 - 1
the vertex is at (3,-1)
Break even is the value of t where revenue=cost or R(t)=C(t)
set equal each other
-50t^2+300t=600-50t
multiply both sides by -1
50t^2-300t=50t-600
divide both sides by 50
t^2-6t=t-12
minus t-12 from both sides
t^2-7t+12=0
factor
(t-4)(t-3)=0
set each to zero
t-4=0
t=4
t-3=0
t=3
the cost is $3 or $4
it will first break even at t=3$
Answer:
Step-by-step explanation:
D=√((-5+2)²+(-4+1)²)=√(9+9)=3√2≈4.24
