Answer:
Step-by-step explanation:
Given
Required
Determine the
<em>- sin</em>
<em>- cosine</em>
<em>- tangent</em>
of an angle
The given expression can be represented as follows;
Where A = 94 and B = 37
In trigonometry:
Substitute 94 for A and 37 for B
Hence, the angle is 57;
<em>Since 57 is not a special angle; I'll solve using a calculator</em>

Answer:
The principal investment required to get a total amount of $ 1,000,000.00 from compound interest at a rate of 6% per year compounded 12 times per year over 45 years is $ 67,659.17.
Step-by-step explanation:
Given
- Accrued Amount A = $1000000
- Interest rate r = 6% = 0.06
- Time period t = 45 years
- Compounded monthly n = 12
To determine:
- Principle amount P = ?
Using the formula
substituting A = 1000000, r = 0.06, t = 45, and n = 12
$
Therefore, the principal investment required to get a total amount of $ 1,000,000.00 from compound interest at a rate of 6% per year compounded 12 times per year over 45 years is $ 67,659.17.
