Find the common ratio r for the geometric sequence and user to find the next three terms. -6, 18, -54, 162, ...
The common ratio r =
The next three terms are
___,___, and

the common ratio(r): 3

-486,1458,-4374

-486,1458,-4374Step-by-step explanation:

-6×3=18

18×3=-54

54×3=162

162×3=-486

-486×3=1458

1458×3=-4374

therefore the next three terms are,-486,1458,and -4374

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

where is the gragh
