B= 5,3
c=4,-1
a=2,1
this is the answer to part c
3/4 as you are paying for what is not discounted
<span>P=34</span> inches<span>
a= left side=6 inches</span>
b= top side
P=2a+2b<span>
<span>P=34=2*6+2b
34=12+2b
b=11</span></span>
the length of the top side is 11 inches
A+2b=3000
90a+60b=150000
-90a-180b=-127000
90a+60b=150000
-120b=-120000
b=1000
a+2000=3000
a=1000
crop a=1000
crop b=1000
Answer:
0.03125
Step-by-step explanation:
Note that -32 is obtained by multiplying 128 by -1/4, and that 8 is obtained in the same way. Thus, the common ratio is -1/4, and the formula for the nth term of this sequence is
a(n) = 128(-1/4)^(n-1).
Then the 7th term is a(7) = 128(-1/4)^(7-1) = 128(-1/4)^6, or 0.03125.
