Pls me with the blanks and the questions c, d and needed tia

(a) no

(b) yes

(c) y = 900/x^2

(d) 400

(e) about 9.49 m

Step-by-step explanation:

(a) When x and y are inversely proportional, their product is a constant.

  1·900 ≠ 2·225, so x and y are not inversely proportional

(b) When x^2 and y are inversely proportional, their product is a constant.

  1^2·900 = 2^2·225 = 3^2·100, so x^2 and y are inversely proportional

(c) The result from (b) tells you

  x^2·y = 900

or

  y = 900/x^2

(d) For x=1.5

  y = 900/1.5^2 = 900/2.25 = 400

(e) For y = 10

  10 = 900/x^2

  x^2 = 900/10 . . . . multiply by x^2/10

  x = √90 ≈ 9.49 . . . meters

take it another

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
