Answer:
according to me 1st option seems to be correct❤️
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
Rotation about the origin
Hope this helped! the answer is 2^7
The number is assumed to be x
x of 40% = 56
x * (40/100) = 56
x = 5600 / 40
x = 140
