Step-by-step explanation:
Using De Moivre's theorem
Given
[ 4(cos15° + isin15° ) ]³, then
= 4³ [ cos(3 × 15°) + isin(3 × 15°) ]
= 64 (cos45° + isin45° )
= 64 (

i )
= 64 (
(1 + i) )
= 32
(1 + i)
= 32
+ 32

Step-by-step explanation:
The question is incomplete. I will assume the function is:

Required
Determine the rate of decay
In an exponential function
,
The decay rate of the function is calculated as:

By comparison:

So, the equation becomes:

Make r the subject


<em>The rate of decay is 0.14</em>
Answer:
Box A's volume is bigger by 864 cubic inches
Step-by-step explanation:
12 × 18 × 24 = 5184
12 × 12 × 30 = 4320
Then we subtract. 5184 - 4320 = 864
