Answer:
14
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
f(x) - g(x)
= 3x² + 1 - (1 - x)
= 3x² + 1 - 1 + x
= 3x² + x , thus
(f - g)(2)
= 3(2)² + 2 = 3(4) + 2 = 12 + 2 = 14
Answer:
r = 6.146
Step-by-step explanation:
formula for the volume is 4/3πr³
v = 4/3πr³ <u>we adjust the equation for the r</u>
r = ∛3v/4π
r= ∛3*972/4*3.14
r = 6.146
