Answer:
Step-by-step explanation:
(x+1)(x−3)(x−4)
=((x+1)(x−3))(x+−4)
=((x+1)(x−3))(x)+((x+1)(x−3))(−4)
=x3−2x2−3x−4x2+8x+12
=x3−6x2+5x+12
Answer:
The answer is (C.
Step-by-step explanation:
Answer:
48π
Step-by-step explanation:
Given that,
The radius of the sphere is increasing at a rate of 3cm/minute,
The volume of a sphere is given by :
Differentiating both sides wrt t.
Put r = 2 cm and dr/dt = 3 cm/minute
So,
Hence, the correct option is (a) "48π".
Answer:
2008
Step-by-step explanation:
p=282t+644 (subtract 644 from both sides)
p - 644 = 282t (rearrange)
282t = p - 644 (divide both sides by 282)
t = (p - 644) / 282
find t when p = $1320.80
t = (p - 644) / 282
t = (1320.80 - 644) / 282
t = (676.8) / 282
= 2.4 years
since t is measured in years since 2005,
2.4 years after 2005 will put us in 2005 + 2.4 = 2007.4 ( or inside of 2008)
