Answer:
26,244
Step-by-step explanation:
The sequence is geometric with a common ratio of -3. The general term is ...
an = (a1)r^(n-1)
The first term is 4, so we have ...
an = 4·(-3)^(n-1)
For n=9, we find the 9th term to be ...
a9 = 4·(-3)^(9-1) = 4·3^8
a9 = 26,244

When -3 is raised to an even power, the sign of the product is positive, the same as 3 raised to that power.
Answer:
10.47 inches
Step-by-step explanation:
circumference = πD = 3.14(20) = 62.8 inches
62.8 inches/6 spaces = 10.47 inches per space
The factorization of the polynomial would be: y = (x - 5)(x - 7).
There are two x-intercepts at 5 and 7. Therefore, those are the zeros of the functions. Using those 2 values, we can write the following factors:
(x - 5) and (x - 7)
