On a sketch of \( y = \ln(x) \), represent the left-endpoint approximation with \( n = 2 \) approximating \( \int_1^2 \ln(x) \, dx \). Write out the terms of the sum, but do not evaluate it:

Sum = \[ \underline{\hspace{2cm}} \] + \[ \underline{\hspace{2cm}} \]

On another sketch, represent the right-endpoint approximation with \( n = 2 \) approximating \( \int_1^2 \ln(x) \, dx \). Write out the terms of the sum, but do not evaluate it:

Sum = \[ \underline{\hspace{2cm}} \] + \[ \underline{\hspace{2cm}} \]

Which sum is an overestimate?
- A. the left Riemann sum
- **B. the right Riemann sum**
- C. neither sum

Which sum is an underestimate?
- **A. the left Riemann sum**
- B. the right Riemann sum
- C. neither sum

The velocity of a car is \( f(t) = 7t \) meters/second. Use a graph of \( f(t) \) to find the exact distance traveled by the car, in meters, from \( t = 0 \) to \( t = 10 \) seconds.

[Input box for distance]

Note: Include units in your answer.
