We have that the stream of water is coming out in small quantities; at most liters at a time since the stream has a width of around 10cm at most times. Hence, cubic meters per second is too large a unit to measure the small quantity of water going through the shower.
We have that we can calculate the rate if we know the surface area of the flow and the speed of the water. If one multiplies those 2 together, one gets the rate because the speed of water is pretty much how much a front of water is moving per second; if you multiply it by its surface area, you get how much a volume of water is moving.
I believe it is C but I’m not sure
Answer:
Step-by-step explanation:
by theorem :
f continu in [1 , 2]
f(1)×f(2) < 0 because : f(1) = -1 and f(2) = 15
so the equation f(x)=0 has at least one real root between x=1 and x=2
so :
Answer:
60/120/180
Step-by-step explanation:
Either of these would work because it must be an even number divisible by 2.
It must end in a zero : divisible by 5 but even.
It must be a multiple of 30 as 3 only goes into 10s at 30. And that takes care of the 6 too.
But 4 doesn't go into 30, so 60?….
Yes, 60 is divisible between 2, 3, 4, 5 and 6
But the question does not limit your answer to one solution.
I hope this helps! :)
