-7/12=y/-36
times both sides by -36 (-36=12*-3)
-3*-7=y
21=y
y=-21
Answer:
A = 846 in²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = 
× d₁ × d₂ ( d₁ and d₂ are the diagonals ) , then
A = × 36 × 47 = 18 × 47 = 846 in²
For the answer to the question above,
a1 = 40
<span>a2 = 20 </span>
<span>a3 = 10 </span>
<span>.. </span>
<span>aN = (1/2^N-1) a1 { in general aN= (r^N-1) A1 </span>
<span>a5 = (1/2^4) 40 = 40/16 = 2.5
</span>
So the answer to your question is 2.5
