Transcribed Image Text:A reservoir is 80m long and its cross section is an isosceles trapezoid having
equal sides of 10m, an upper base of 17m, and a lower base of 5m. At the instant
5.
when the water is 5m deep, find the rate at which the water is leaking out if the
water level is falling at 0.1m/hr. (Volume of a trapezoidal prism
is + hl, where a and b are bases of the trapezoid, h is the height of the trapezoid,
2
and l is the length of the prism.)
