The volume of water that goes into the hose is the same as the volume of water that comes out the nozzle. This means the velocity is inversely proportional to the area. The area is proportional to the square of the diameter.

Taken together, these facts mean that if the diameter is divided by a factor of 3, the velocity is multiplied by a factor of 3^2 = 9.

Nozzle velocity = 3^2 * entering velocity
.. = 9 * (4 m/s)
Nozzle velocity = 36 m/s . . . . . . . . . corresponding to selection A

A commercial airline makes a flight each day from New York to Paris, France. The aircraft seats 524 passengers and serves 2 meal
nadya68 [22]
Start by multiplying the amount of passengers by 2 (for amount of meals)

524×2= 1,048

That will equal to 1,048, which is the amount of meals given out for a full plane in one day.

Now multiply that by 7 (for one week) and you'll get your answer!

524×2= 1, 028 × 7 = 7, 336 meals

7, 336 meals are given out in a one week time span on a fully packed plane.

Given limit of f (x) = 4 as x approaches 0. what is limit of one-fourth left-bracket f (x) right-bracket superscript 4 baseline
Otrada [13]

The limit of the given function if \lim_{x \to 0} f(x)=4 is 64

<h3>Limit of a function</h3>

Given the following limit of a function expressed as;

\lim_{x \to 0} f(x)=4

We are to determine the value of the function

\frac{1}{4}  \lim_{x \to 0} [f(x)]^4


This can also be expressed as

\frac{1}{4}  \lim_{x \to 0} [f(x)]^4\\ = \frac{1}{4}(4)^4 \\=1/4\times 256\\=64

Hence the limit of the given function if \lim_{x \to 0} f(x)=4 is 64
