(1 point) Sequences of Partial Sums. Part 1. Compute the first four terms of the sequence of partial sums for the series: ∑n=1[infinity](12)n−1 S1= S2= S3= S4= Note: answers should be simplified and should not contain decimals. Part 2. Find a formula for the nth partial sum, Sn, that depends only on n. Sn= Part 3. Evaluate the following limit to determine whether the given series converges or diverges. limn→[infinity]Sn= Therefore, the series . Note: type either 'converges' or 'diverges' in the last blank.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16
