Answer:
4 tents
Step-by-step explanation:
22/6 = 3.66666666667
Then you round to get 4
(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
2nd option is answer
Answer:
48 fluid ounces.
Step-by-step explanation:
8 fluid ounces = 1 cup
So, we need to multiply 8 by 6.
8 x 6 = 48...That's your answer!
Answer:
∠ A = 60°
Step-by-step explanation:
Consecutive angles in a parallelogram sum to 180° , then
∠ A + ∠ B = 180° ( substitute ∠ B = 2 ∠ A )
∠ A + 2 ∠ A = 180°
3 ∠ A = 180° ( divide both sides by 3 )
∠ A = 60°
