I believe it would be the first option.
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
-33/8 or -4 1/8
Hope this helps!
The answer is A because that information they gave to you
Answer:
Putting the value of x of coordinate point (12,-2)
where x= 12
y= 5×12/6 -12
= 5(2)-12
=10-12 = -2
option D
