Answer:
The correct answer is - C) the RICE formula.
Explanation:
The first aid for a patient with a sprain or strain mainly includes the RICE formula which stands for the rest, ice, compression, and elevation. In case of a sprain or strain, one is advised to rest, use ice on the location of the sprain, compression on the part of the sprain, and elevate the body part for less pain, less swelling or reducing chances of making it worst.
The other three formulas given are used in different conditions. The FITT formula used in the exercise planning, and the ABC formula used for the first aid of the heart attack or blockage of the airway.

Answer:
<h2>0.245cm/min</h2>
Explanation:
The volume of the spherical balloon is expressed as V = 4/3πr³ where r is the radius of the spherical balloon. If the spherical balloon is inflated with gas at the rate of 500 cubic centimetres per minute then dV/dt = 500cm³.
Using chain rule to express dV/dt;
dV/dt = dV/dr*dr/dt
dr/dt is the rate at which the radius of the gallon is increasing.
From the formula, dV/dr = 3(4/3πr^3-1))
dV/dr = 4πr²
dV/dt = 4πr² *dr/dt
500 = 4πr² *dr/dt
If radius r = 40;
500 = 4π(40)² *dr/dt
500 = 6400π*dr/dt
dr/dt = 500/6400π
dr/dt = 5/64π
dr/dt = 0.245cm/min
Hence, the radius of the balloon is increasing at the rate of 0.245cm/min
