We can simply add the expression to simplify the expression. So,
(7+3i)+(-8+9i) =7 +3i -8+9i Get rid of paranthesis.
=(7-8)+(3i+9i) Group the like terms.
= -1 + 12i
For this case we have the following expression:
h (t) = -16t ^ 2 + 64t + 80
For t = 0 we have:
h (0) = -16 (0) ^ 2 + 64 (0) + 80
h (0) = -0 + 0 + 80
h (0) = 80 feet
Therefore the number 80 represents the initial height of the rocket
Answer:
the 80 in the expression represented:
the initial height of the rocket
