The rockets rate of change in miles per second is:
(5 - 1)/(2.5*60 - 30) = 1/30 miler per second or 0.033
the rockets rate of change in miles per minute is:
(5 - 1)/(2.5 - 30/60) = 2 miles per minute
Answer:
38 + 37i
Step-by-step explanation:
(9 − 4i)(2 + 5i)
FOIL
first: 9*2 = 18
Outer: 9*5i = 45i
inner: -4i * 2 = -8i
last : -4i * 5i = -20i^2 = -20(-1) = 20
Combine together
18+45i-8i +20
38 + 37i
