Answer:
1.5
Step-by-step explanation:
6/4=3/2
3/2=1 1/2
or
1.5
It’s 7 1/2 because 4x3 gives you the length of the bigger rectangle so, you multiply 2 1/2x3 and get 7 1/2 :)
I think the answer is B and C
Answer:
−0.989010989010
Step-by-step explanation:
what is the 45th term of a sequence generated by the formula tn=(-1)^n * (2n/2n+1)?
When n= 45
tn=(-1)^n*(2n/2n+1)
tn = (-1)^45 * ( 2(45) / 2(45) + 1
= -1 * 90 / (90+1)
= -90 / 91
= −0.989010989010
The 45th term of the sequence generated by the formula tn=(-1)^n*(2n/2n+1) is −0.989010989010
