Parabola
remember that
parabola equation is
4p(y-k) =(x-h)^2 for a verticl parabola
p=distance from vertex to focus and from vertex to directix
solve for p, k, h
y=0.6x^2
4p(y-0)=(x-0)^2
divide both sides by 4p
(y-0)=1/4p times (x-0)^2
y=0.6x^2
1/(4p)=0.6
find p
multiply 4p
1=2.4p
divide 2.4
1/2.4=p
h=0,k=0
vertex=0,0
opens up so go up to find focus
(0,0)
0+1/2.4=1/2.4
focus is at (0,1/2.4)
Th answer to number 1 is B. The answer to number 2 is C. The answer to number 3 is A. The answer to number 4 is the first graph {(1,80),(2,240),(3,720),(4,2160)}
Answer:
Step-by-step explanation:
given that an article in the Sacramento Bee (March 8, 1984, p. A1) reported on a study finding that "men who drank 500 ounces or more of beer a month (about 16 ounces a day) were three times more likely to develop cancer of the rectum than non-drinkers."
To support this some data collected should be given. The data should be from a sample of a large size randomly drawn from 2 groups one men who drank 500 oz or more of beer and other group not drank that much. These people medical history with cancer patients number also should have been given.
Inclusive means within and the number n, while exclusive means within and without the number n
