The height of a toy rocket during a 2.35 second flight is predicted by the function h(t) = –4t 3 + 6t 2 + 8t, where h is the height in meters and t is the time in seconds. This model is an example of a polynomial function. Find the height of the toy rocket 1.25 seconds into the flight

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

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)
