Answer:
-12x^2+42x-6
Step-by-step explanation:
Answer:
V = 4000 cm^3
Step-by-step explanation:
The volume of the sphere is given by
V = 4/3 pi r^3
We are given the radius of 10 and are to use 3 for pi
V = 4/3 (3) * (10)^3
V = 4/3 *3 * 1000
V = 4000 cm^3
Hence, the percentage increment is 33.25%
Answer and Step-by-step explanation:

Decreased by 20%
Answer: Answer is $21
Step-by-step explanation:
Using the equation C = P + (P)(T)
where P= $20
T= 5%; 5/100 = 0.05
Substitute the figures in the equation,
$20 + $20 (0.05)
Apply BODMAS and open bracket first
$20 + $1
= $21
