Question

for a function that is strictly decreasing, a right hand riemann sum is which of the following: overestimate, underestimate, exact solution, unable to determine

Explanation:

A right-hand Riemann Sum uses the right endpoint of each subinterval to determine the height of the rectangles. For a strictly decreasing function, the right endpoint of each subinterval is the smallest value of the function on that interval. This means the area of each rectangle is smaller than the actual area under the curve over that subinterval, so the total sum will be smaller than the true integral value.

Answer:

Overestimate
