Answers:
a. 0.5 people
b. 10 spring rolls will serve 5 people, 16 spring rolls will serve 8 people, 25 spring rolls will serve 12.5 people
c. n/2 or 1/2 of n
Step-by-step explanation:
if 6=3p, p representing each person, then we find that 2 spring rolls serve 1 person, so 1 spring roll serves 0.5 people!
if 1=0.5p, then p is 1/2 of the amount of spring rolls.
Divide each of the amount of spring rolls by 2.
10=5p
16=8p
25=12.5p
n=n/2
The variable p is important, as to show that it's the amount of people.
Hope this helps!

Answer:
table C
Step-by-step explanation:
The constant of proportionality k= y/x
table C shows constant proportionality :
90/9=140/14=240/24=10
The standard equation of a circle is expressed as
(x - h)^2 + (y - k)^2 = r^2
where
h is the x coordinate of the center of the circle
k is the y coordinate of the center of the circle
r is the radius of the circle(the distance from the center of the circle to the circumference
From the graph,
h = - 1
y = 4
r = 5
By substituting these values into the equation, we have
(x - - 1)^2 + (y - 4)^2 = 5^2
(x + 1)^2 + (y - 4)^2 = 25
Thus, the equation of the circle is
(x + 1)^2 + (y - 4)^2 = 25

Answer:
y = - 
(x - 1)² + 2
Step-by-step explanation:
Any point (x, y) on the parabola is equidistant from the focus and the directrix.
Using the distance formula
= | y - 6 |
Square both sides
(x - 1)² + (y + 2)² = (y - 6)² ( expand the factors in y )
(x - 1)² + y² + 4y + 4 = y² - 12y + 36 ( subtract y² - 12y from both sides )
(x - 1)² + 16y + 4 = 36 ( subtract 4 from both sides )
(x - 1)² + 16y = 32 ← subtract (x - 1)² from both sides )
16y = - (x - 1)² + 32 ( divide all terms by 16 )
y = - (x - 1)² + 2
