Answer:
The correct answer is v(t) = (principal × time × 0.02) if calculated simply and v(t) = Principal × where v(t) is the interest after t years .
Step-by-step explanation:
Principal amount invested by Shota is $2000.
Interest is earned at 2% per year.
Time for which the principal is invested is t years.
Therefore let the total interest be v(t) dollars in t years.
Case 1: Simple Interest.
v(t) = (principal × time × ) = (2000 × t × 0.02) = 40t
Case 2: Compound Interest.
v(t) = Principal × - Principal = 2000 ×
- 2000.
Answer:
A The solution is a point in the coordinate plane.
Step-by-step explanation:
The slope of each of these lines is the coefficient of x. The slopes are different, so the lines must intersect in one point. That point is not on either of the x- or y-axes.
The solution set is a point in the coordinate plane.
__
Since these are equations, the solution set is not a region. It would be a region if these were inequalities.
