If a varies directly as the cube root of b and if a=3 and b=64.find the formula connecting the variables hence find b when a=15/
Liono4ka [1.6K]

Answer:

b = 125

Step-by-step explanation:

Given a varies directly as \sqrt[3]{b} then the equation relating them is

a = k\sqrt[3]{b} ← k is the constant of variation

To find k use the condition a = 3 , b = 64 , then

3 = k\sqrt[3]{64} = 4k ( divide both sides by 4 )

\frac{3}{4} = k

a = \frac{3}{4} \sqrt[3]{b} ← equation of variation

When a = \frac{15}{4} , then

\frac{15}{4} = \frac{3}{4} \sqrt[3]{b} ( multiply both sides by 4 to clear the fractions )

15 = 3\sqrt[3]{b} ( divide both sides by 3 )

5 = \sqrt[3]{b} , then

b = 5³ = 125
