Answer: y = (5x)^2

Step-by-step explanation: You're finding the inverse.

  • f(x) = \sqrt{x}/5 --> y = \sqrt{x}/5 (they mean the same thing)
  • x = \sqrt{y}/5 (switch x and y)
  • 5x = \sqrt{y} (multiple both sides by 5)
  • (5x)^2 = y (square both sides) --> the first answer choice

6^2r=800 round it to the nearest hundreth

Question: solve for r: 6 ^ (2r) = 800


Answer: 1.87


Step-by-step explanation:

6 ^ (2r) = 800

log(6 ^ (2r)) = log(800)

2r log(6) = log(800)

r = log(800) / (2 log(6))

r = 1.86537641979

round

r = 1.87

log can be any logarithm function.


6^(2×1.86) = 784.734328546

6^(2×1.87) = 813.365367336
