Answer:
1. b = kt²
2. Y = k / 3√r
3. r = ktu
4. m = kn² / p
Step-by-step explanation:
1. b varies directly with the square of t
b = k * t²
b = kt²
2. Y is inversely proportional to the cubre root of r
Y = k / 3√r
3. r varies jointly as t and u
r = k * t * u
r = ktu
4. m varies directly as the square of n and inversely to p
m = (k * n²) / p
m = kn² / p
1. b = kt²
2. Y = k / 3√r
3. r = ktu
4. m = kn² / p
