Answer:
4. -1
5. +_ 2/5
6. 3.5
Step-by-step explanation:
Answer:
23
Step-by-step explanation:
supplementary angles: 180-85 = 95
95 = 5x-20 ( i forgot the name of the rule, something relating to same side interior angles i think)
115 = 5x
23= x
hope that helped
If they are all 5 dollars then it will be $15
The domain is all ur x values...the range is all ur y (or f(x) values
so ur domain is : { -6,-1,0,3}....1st answer choice
(x-h)^2=4p(y-k)
we know it is this one because the directix is y=something and not x=something
(h,k) is the vertex
p is the distance from the vertex to the focus
it is 1/2 the distance from the vertex to the directix
if p is positive, the focus is above the vertex
if p is negative, the focus is below the vertex
we have
focus is (6,2) and directix is y=1
distance from (6,2) to y=1 is the distance from 2 to 1 which is 1
1/2=p
since 1<2, we see that the focus is above the vertex (when the focus is greater than the directix, then the graph opens to the right or up)
p=1/2
1/2 below (6,2) is (6,1.5)
vertex is (6,1.5)
p=1/2
(x-6)^2=4(0.5)(y-1.5)
(x-6)^2=2(y-1.5)
(x-6)^2=2y-3
2y=(x-6)^2+3
divide both sides by 2
y=1/2 times (x-6)^2+3/2
f(x)=1/2 times (x-6)^2+3/2
