Suppose y varies inversely with x, and y = 25 when x = 1/5. What is the value of y when x = 5 ?
34kurt

Answer:

y = 1

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition y = 25 when x = \frac{1}{5} , then

25 = \frac{k}{\frac{1}{5} } = 5k ( divide both sides by 5 )

5 = k

y = \frac{5}{x} ← equation of variation

When x = 5, then

y = \frac{5}{5} = 1

They met 480 meters from the house.

<h3><u>Calculus</u></h3>

Given that Noah and his grandfather were returning home from a walk, and when they were 800 m away from the house, the grandfather said that he was thirsty, so Noah immediately ran home, got a bottle of water, and ran back to meet his grandfather who never stopped walking at a steady pace, to determine how many meters from the house did they meet if noah ran four times as fast as his grandfather walked, the following calculation must be made:

  • 200 x 4 = 800 - 200 = 600
  • 300 x 4 = 1200 - 800 - (800 - 300) = 100
  • 325 x 4 = 1300 - 800 - (800 - 325) = -25
  • 320 x 4 = 1280 - 800 - (800 - 320) = 480 - 480 = 0

Therefore, they met 480 meters from the house.
