Answer:
$455
Step-by-step explanation:
The computation of the principal is shown below:
As we know that
Amount = Simple interest + Principal
Let us assume the principal be X
So,
Amount = $500
Simple interest = Principal × rate of interest × time period
= X × 5% × 2 years
= X × 0.1
So, the principal is
$500 = X × 0.1 + X
$500 = 1.1 × X
So, the X is $455 i.e principal
Answer:
1` 17/18 PI
Step-by-step explanation:
FORMULA: pi radius squared times height
So from this that one solution is 3+4i so from this result that the other solution may be 3-4i because these are complex number roots
