18. Determine the common difference, the fifth term, and the sum of the first 100 terms of the following sequence:
Ksenya-84 [330]

a_1=1,\ a_2=2.5,\ a_3=4,\ a_4=5.5,\ ...\\\\a_2-a_1=2.5-1=1.5\\a_3-a_2=4-2.5=1.5\\a_4-a_3=5.5-4=1.5\\a_{n+1}-a_n=1.5=constans\\\\\text{It's an arithmetic sequence with}\\a_1=1,\ \boxed{d=1.5}\\\\a_n=a_1+(n-1)d\to a_n=1+(n-1)(1.5)=1+1.5n-1.5\\\\a_n=1.5n-0.5\\\\a_5=1.5(5)-0.5=7.5-0.5=7\\\boxed{a_5=7}\\\\\text{The formula of a Sum of the First n Terms of an Arithmetric Sequence:}\\\\S_n=\dfrac{2a_1+(n-1)d}{2}\cdot n\\\\\text{We have:}\\a_1=1,\ d=1.5,\ n=100\\\\\text{Substitute}

S_{100}=\dfrac{(2)(1)+(100-1)(1.5)}{2}\cdot100=\dfrac{2+(99)(1.5)}{1}\cdot50\\\\=(2+148.5)\cdot50=150.5\cdot50=7,525\\\\\boxed{S_{100}=7,525}\\\\Answer:\\the\ common\ difference:\ d=1.5\\the\ fifth\ term:\ a_5=7\\the\ sum\ of\ first\ 100\ terms:\ S_{100}=7,525

What is the volume of the cylinder below?
Diano4ka-milaya [45]

Answer:

Volume = 252π units³

Step-by-step explanation:

We have been given an obliques cylinder (a cylinder having its bases parallel to each other but are not aligned).

The volume of an oblique cylinder can be found similarly to that of a regular cylinder, with using the formula:

Volume = Base · Height

Where the height in the regular cylinder is taken as the distance from one base to another base, but for oblique cylinder, the height is taken as the perpendicular distance from one base to another base, which in the given diagram, is shown as 7

So, for the given cylinder:

Height = 7

Radius = 6

Volume = Base · Height

Volume = πr² · h

Volume = π(6)² · 7

Volume = 252π units³
