Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in the simplest form 12,7
Ivanshal [37]

Answer: common difference = -5

Step-by-step explanation:

This is an arithmetic progression. The common difference will be gotten by subtracting the 1st term from the 2nd term. This will be:

1st term = 12

2nd term = 7

3rd term = 2

Common difference = 7 - 12 or 2 - 7 = -5

It isn't an geometric progression as the ratio isn't thesame

= 2nd term / 1st term

= 7/12

= 3rd term / 2nd term

= 2/7

Therefore, it's an arithmetic progression with difference of -5

Find the base hei ght when the volume is 10,125 cubic meters.
joja [24]

Answer:

15 m

Step-by-step explanation:

cross-section area=1/2×45×x m ²

height = 30 m

volume=10125m³

we have

volume = cross-section area×height

10125 = ½×45×x×30

x=10125×2/(45×30)

x=15m
