arrow pointing to the left (<) is less than
so the correct answer would be e < 2000
Answer:
Yes that is reasonable
Step-by-step explanation:
As, we will take p = 12
So, the negative number = 24
So 12-24 = - 12
So therefore it's reasonable
Answer:
poop
Step-by-step explanation:
Hello,
cos θ =-1 or cos θ =-1/2
Indeed:
cos 2θ =2 cos² θ -1
cos 2θ +3 cos θ+2=0
==>2 cos² θ -1+3 cos θ+2=0
==>2 cos² θ +3 cos θ+1=0
Δ=3²-4*2=1
cos θ =(-3-1)/4=-1 or cos θ =(-3+1)/4=-1/2
We must verify:
if cos θ =-1 then 2*(-1)² -1 +3*(-1)+2=2-1-3+2=0
if cos θ =-1/2 then 2*(-1/2)² -1 +3*(-1/2)+2=2*1/4-1-3/2+2=1/2-3/2+1=0
