A bullet is shot upwards and its trajectory can be modeled by the function h(t) = -t^4 + 15t^3 - 150t^2 + 1600t + 3000, where h(t) is measured in meters and t is the number of seconds since the bullet is shot. At what second did the bullet hit the ground?

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)
