Biologists have concluded that primates were invaded millions of years ago by some of the endogenous retroviruses.
OK.
But before that, where did those retroviruses come from. Did they originate in some other non primate animal. If they were from some other non primate animal, does that mean they caught it from yet some other animal.
Was there some animal that had it on its own without catching it from other animals.

Given:

z= 2((cos 3pi/4) + i sin (3pi/4))

w = 3((cos pi/2) + i sin (pi/2))

I have to calculate the following & leave in polar form:

a) z *w

which I got: 6((cos 3pi/4 + pi/2) + i sin (3pi/4 + pi/2))

b) z/w

which I got: 2/3 ((cos 3pi/4 - pi/2) + i sin (3pi/4 - pi/2))

c) z^4

I need help with these one

please help and explain step by step so i can follow, thanks

ALSO ARE THE OTHER TWO RIGHT???

an 85 g wooden block is set up against a spring. The block rests on a smooth surface. The block is pushed into the spring, compressing it a distance of 2.0 cm and then released. The spring constant is k=78 N/m. What is the speed of the block when it reaches its initial position ( where the spring was not compressed)?
