Answer: x = \sqrt{320}, or 17.8885438

Step-by-step explanation:

According to the pythagorean theorem, a^2 + b^2 = c^2.

As such, 4^2 + x^2 = (4sqrt5)^2

16 + x^2 = 80

x^2 = 64

x = 8.

Thus, the dashed line in the center is 8.

Simply plug this into the pythagorean theorem as well.

8^2+16^2=p^2

p^2 = 320

p = 17.8885438, or sqrt 320

Answer please? ___ feet per second
Oksanka [162]

Answer: 30 feet per second

========================================

x = diameter, y = speed of water

y varies inversely with respect to x, so, y = k/x for some constant k

If x = 0.6 and y = 5 pair up, then y = k/x turns into 5 = k/0.6 which solves to k = 3 when you multiply both sides by 0.6

So the equation y = k/x turns into y = 3/x

Now plug in the diameter x = 0.1 to find the speed to be...

y = 3/x

y = 3/0.1

y = 30 feet per second
