Answer:
6307.5
Step-by-step explanation:
Hope that helps!
<span>Since we need to convert “miles per second” to “miles per hour,” we first need to find out how many seconds there are in a hour.
We know that there are 60 seconds in a minute, and if we wanted to do an hour we would have to do 60 * 60 which is 3600 seconds, therefore,
</span>1 mi/57.1 sec = (1 mi/ 57.1 sec)(3600 sec/1 hour)
= (3600/57.1) mi/hours
<span> = 63.047 mi/hours</span>
We have to multiply given (3-2i)(3+2i)
(3-2i)(3+2i)=9-6i+6i+4i^2
9+4i^2
We know that i^2=-1, so lets substitute it
9+4*(-1)=9-4=5
:answer (x+5−4)(x+5+4)(x−4)
how i got it:
(x+5−4)(x−(−
2
2(5+4)
))(x−4)
