Inversely proportional to the square root of x+4 with k=6 find y when x=77

To solve this problem, we can use the formula for inverse variation:

y = k / √(x + 4)

Given that k = 6 and x = 77, we can substitute these values into the formula:

y = 6 / √(77 + 4)

y = 6 / √81

y = 6 / 9

y = 2/3

Therefore, when x = 77, y is equal to 2/3.
