Answer:

Samuel needs 23 pieces of wood.  Theresa needs 46 pieces of wood.  

Step-by-step explanation:

Samuel:

\frac{346 feet}{15 feet} = 23.06 = 23 pieces of wood

Theresa:

If Theresa needs twice as much wood as Samuel needs, and Samuel needs 23 pieces of wood, then she needs 46 pieces of wood, since 23 x 2 = 46.

determine if the sequence is geometric or arithmetic and find the ratio or difference. -1, 6, -36, 216
andrew-mc [135]
The sequence is an geometric progression;
Nth=a₁r^(n-1)
a₁ is the first term=-1
r=ratio=a₂/a₁=6/-1=-6

Nth=-1(-6^(n-1)

NTh=an

a
₁=-1(-6⁰)=-1
a₂=-1(-6¹)=6
a₃=-1(-6²)=-36
a₄=-1(-6³)=216

therefore this serie is rising at an increasing fast speed, it is an geometric progression.
