Answer:
11. a) P = 27t³/8
b) 27
c) t = [tex]\sqrt[3]{\frac{64}{81} }[/tex]
12. a) V = 2x³
c) A = 10x²
Step-by-step 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 = [tex]\sqrt[3]{\frac{64}{81} }[/tex]
--------
V = x * x * 2x = 2x³
--------
A = 2(x * x) + 2(x * 2x) + 2(x * 2x) = 2x² + 4x² + 4x² = 10x²
