10 to the power of 3, because it equals 1,000, which exceeds 972. I'm in elementary school, so I am not too sure if this is what you are asking. Hope it helps.
Yuto is correct because he isolated the variable correctly and reversed the inequality symbol.
x < 3
Split up the interval [2, 5] into
equally spaced subintervals, then consider the value of
at the right endpoint of each subinterval.
The length of the interval is
, so the length of each subinterval would be
. This means the first rectangle's height would be taken to be
when
, so that the height is
, and its base would have length
. So the area under
over the first subinterval is
.
Continuing in this fashion, the area under
over the
th subinterval is approximated by
, and so the Riemann approximation to the definite integral is
and its value is given exactly by taking
. So the answer is D (and the value of the integral is exactly 39).
