Answer:
-4(4+2)+234-9=201
Step-by-step explanation:
a.
b. Not exactly sure how DeMoivre's theorem is relevant, since it has to do with taking powers of complex numbers... At any rate, multiplying 
and 
is as simple as multiplying the moduli and adding the arguments:
c. Similar to (b), except now you divide the moduli and subtract the arguments:
The first thing we must do is subtract both speeds.
We have then:
64.4 km / h - 64.0 km / h = 0.40 km / h
We now change units taking into account the following conversions:
1h = 3600s
1km = 3280.84 feets
We have then:
0.40 * (3280.84 / 3600) = 0.364537778 feet / s
Answer:
a zebra is faster 0.364537778 in feet per second
Answer:
-10b + 90
Step-by-step explanation:
-10 (b- 9)
-10 ×( b -9 )
-10b + 90
