2 cry = 1 polar equations form is
Answer:
y=(x-2)²+2
Step-by-step explanation:
y=x²-4x+6 (a=1 , b=-4 , c=4)
vertex form : y=a(x-h)²+k
h and k are the vertex coordinate :
h=-b/2a =-4/-2
h=2
find f(2) to find k in the equation :x²-4x+6
(2)²-4(2)+6
4-8+6=2 (k=2)
vertex form : y=a(x-h)²+k (a=1)
y=(x-2)²+2
Answer:
-6/5
Step-by-step explanation:
The slope is computed from ...
slope = (change in y)/(change in x)
= (-2 -4)/(3 -(-2)) = -6/5
Answer:
0= -30
Step-by-step explanation:
Answer:
.2
Step-by-step explanation:
The probability has to sum to 1
Red + yellow + green + black + white = 1
.25+ .30 + .05 + black + white = 1
.6 + black + white =1
subtract .6 from each side
.6-.6+ black + white = 1-.6
black + white = .4
They said black and white received the same number of votes, so they will have the same probability
2 black = .4
Divide by 2
2 black /2 =.4/2
black =.2
