Appears the correct answer is not up there:
The perimeter of the curve portion is 3.14*6/4=10.7
Then you have to add 3+3 for the other 2 sides
So the answer is actually 16.7

What is the 6th term of the geometric sequence where a1 = 1,024 and a4 = −16? 1 −0.25 −1 0.25
VLD [36.1K]

The n-th term is given by

a_n=a_1\cdot r^{(n-1)}\qquad\text{where r is the common ratio}

Then we can find the common ratio from the given terms.

\dfrac{a_4}{a_1}=\dfrac{a_1\cdot r^{(4-1)}}{a_1}=r^3=\dfrac{-16}{1024}=\left(\dfrac{-1}{4}\right)^3\\\\r=\dfrac{-1}{4}\\\\a_6=1024\left(\dfrac{-1}{4}\right)^5=-1

The appropriate choice is -1.

forsale [732]

Answeryou'll be able to ride 14 miles.

Step-by-step explanation:

Your price is 29.50. if the first mile is 3.50 you'll subtract that from the 29.50 you originally had. Now you're left with 26.00. If you divide that by the two dollars you pay for every next mile you'll have 13 miles. Now add that first mile and you have 14. Hopefully  this made sense!
