Answer:
Step-by-step explanation:
we know that distance d from the focus to P should be the same to the distance from P to the directrix
(x-h)^2=4p(y-k)
we need to find the y coordinate,
x is the same from focus, 3
y=(3, (4+2)/2)=(3,3)
we find p now by subtracting the y from the focus from the y that we just found
p=4-3=1
again (x-h)^2=4p(y-k), p=1
(x-3)^2=4(1)(y-3)
(x-3)^2=4(y-3), (x-3)^2=4y-12
simplify
4y=(x-3)^2+12
y=((x-3)^2)/4 + 3

Using proportions, it is found that the number of islands that each member will have to visit is given by:
c. 19 islands.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, there are 684 islands, and 36 members, hence the number of islands per member is given by:
n = 684/36 = 19.
Which means that option c is correct.

Answer:
20 years apart.
Step-by-step explanation:
Daughter is 10 years old, and mother is 3 times older. This makes mother 30 years old. There is a 20 year difference between them.
Ten years later, the daughter is 20 years old. Since the mother is 20 years older, she is now 40, which is 2 times older than the daughter.
Step-by-step explanation:
HERE,
redius of a circle (r)=14 meters.
we know that,
<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>
circle circumference=
so, the circumference of that circle is <em><u>8</u></em><em><u>8</u></em><em><u> </u></em><em><u>meters</u></em><em><u>.</u></em>
