Question

Please I need this in 15 min so please could u send it asap​

Answer 1

11. a) P = 27t³/8

b) 27

c) t =
`\sqrt[3]{(64)/(81) }`

12. a) V = 2x³

c) A = 10x²

Explanation:

P = a * t³

1 = a * (2/3)³

a = 27/8

P = 27t³/8

--------

P = 27(2)³/8 = 27

--------

8/3 = 27t³/8

t =
`\sqrt[3]{(64)/(81) }`

--------

V = x * x * 2x = 2x³

--------

A = 2(x * x) + 2(x * 2x) + 2(x * 2x) = 2x² + 4x² + 4x² = 10x²
