Water is released into a tank at the rate r(t) = 5 + √ t ft3/min at time t (in minutes). at time t = 1, there is 12 ft3 of water in the tank.

(a) evaluate z 6 1 r(t) dt, rounding your answer to two decimal places.

(b) in the context given above, what does the value in part (a) tell us?

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

what is the original number? you forgot to add it.
