If y varies inversely as the square of x, and y = 1/8 when x = 1, find y when x = 5.

Answers

y = k / x² ( y varies inversely as the square of x ) 
y = 1/8 when x = 1:
1/8 = k / 1²
8 k = 1
k = 1/8
For x = 5:
y = 1/8  / 5² = 1/8 : 25 = 1/8 · 1/25 = 1/200
Answer: A ) 1/200

I don't understand it

Answers

(a+b)(a-b) = a^2 - b^2

(1+5/6) (1-5/6) = 1^2 - (5/6)^2 = 1 - 25/36 = 36/36 - 25/36 = (36-25)/36 = 11/36

11/36 is your answer

Answers

Answer:

E. 2 1/2

E. 8.5 cm

C. 6 cm

Step-by-step explanation:

4............................

Scale factor = AE/AC = (4+6)/4 = 10/4 = 2.5

Correct option isE. 2 1/2

5............................

DE = ?

  • DE = √AD² - AE² = √15² - 10² = √125 = 5√3 ≈ 8.66
  • For measure of AD see next question (6)

Close option isE. 8.5 cm

6............................

AB = ?

  • AD/AB = 2.5 the scale factor as per question 4
  • (AB + 9)/AB = 2.5
  • 2.5*AB = AB + 9
  • 1.5*AB = 9
  • AB = 9/1.5
  • AB = 6 cm

Correct optionC. 6 cm
