Question

Write an equation for each the following

1. b varies directly with the square of t
2. Y is inversely proportional to the cubre root of r
3. r varies jointly as t and u
4. m varies directly as the square of n and inversely to p​

Answer 1

1. b = kt²

2. Y = k / 3√r

3. r = ktu

4. m = kn² / p

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
