Answer:
d. 76(cos(3π/16) +i·sin(3π/16))
Step-by-step explanation:
To form the product of 38cis(π/8) and 2cis(π/16), multiply the magnitudes and add the angles:
38cis(π/8) × 2cis(π/16) = (38×2)cis(π/8 +π/16) = 76cis(3π/16)
___
In this context, a·cis(b) ≡ a(cos(b) +i·sin(b))
Answer:


Step-by-step explanation:
Given

Represent using an inequality and solve
Let the number of dollars be represented by n
<em>If 1 withdrawal is $20 bill</em>
<em>n withdrawals would be $20n bills</em>
The total withdrawal and the minimum balance must be less than or equal to the available balance.
So, this gives

Substitute values for each of these

Solving for n


Divide through by 20

But n can not be decimal because it represents number of dollar bills , which must always be an integer.
So, we round down the value of n

The volume is multiplied by 8. For example if you have a 1x1x1 cube the volume is 1. If you have a 2x2x2 cube the volume is 8. If you have a 4x4x4 the volume is 64.
