Y is inversely proportional to the square of x.
A table of values for x and y is shown.

X 1 2 3 4
Y 4 1 4/9 1/4
a, Express y in terms of x.
b, work out the positive value of x when y = 25

Part a

y is inversely proportional to the square of x.

That means there's some proportionality constant k such that

y = k/x²

We have points (1,4), (2,1), (3,4/9), (4,1/4)

4 = k/1² = k

y = f(x) = 4/x²

We check the other points, f(2)=1, good, f(3)=4/9 good, f(4)=1/4 good

y=4/x²

Part b, y=25

25 = 4/x²

x² = 4/25

x = 2/5

 2/5

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

you forgot the options, but i found them anyways, the correct answer is "john wilson believes that words and actions based on the intellect are superior to those based on emotions".

john wilson is depicted as an extremely intelligent man. the point of the excerpt is to make a sort of distinction between emotional and rational intelligence. he happens to have both attributes, but he clearly favors his intellectual gifts. at the same time, because of his religious background, he's a little bit conflicted with this and it makes him ashamed.

hope this !
