V (Volume) = s^2 * h = 48 ------> h = 48s^-2
C (Cost) = (4sh)(2) + (2s^2)(1) = 2s^2 + 8sh = 2s^2 + 8s(48s^-2) = 2s^2 + 384s^-1
dC/ds = 4s - 384s^-2 = 0 ------> 4s(1 - 96s^-3) = 0
Since s can't be 0, the only possible solution is:
1 - 96s^-3 = 0
s^3 - 96 = 0
s = cube root(96) = 2 cube root(12) ~ 4.579 cm
s^2 = 4 + 2 cube root(18) = 2[2 + cube root(18)]
h = 48/s^2 = 24/[2 + cube root(18)] ~ 5.194 cm
Answer:
(b) The planet's mass =10.241032 kilograms.
Step-by-step explanation:
Here, the mass of Neptune = 1024 1032 milligrams
Also, given: 1 milligram = 0.0000001 kilograms.
or, 1 milligram = 
kilograms.
Now, to convert 1024 1032 milligrams in to kilograms, we get:
1024 1032 milligrams = 
kilograms.
Now solving , we get:
kilograms.
Hence the planet's mass =10.241032 kilograms.
The first question is 1.5
We get that by dividing the amount of coco (6) but the number of cups (4)
The second answer is 4/6 or .666666
We get that but dividing 4 by 6
D any angle no matter how many there totally degree is 360
